People doing Physics

This month we are delighted to welcome Oleg Brandt, a Professor of Experimental Physics in the High Energy Physics group of the Cavendish. Oleg’s journey into the world of particle physics is both captivating and enlightening. From his early days inspired by a remarkable physics teacher directly followed by a rocky start at University, to a transformative experience abroad and a few more pivotal moments along the way, Oleg's insatiable curiosity for the fundamental mysteries of nature and his passion for teaching has led him to Cambridge where he now teaches the next generations of physicists while searching for dark matter, long-lived particles and other exciting new phenomena at CERN’s Large Hadron Collider and beyond. In this episode, Oleg offers a glimpse into the intricate world of particle physics through his unique perspective. Together we talk about the fulfilment and frustrations of a life in research, the importance of feeding one’s curiosity, navigating setbacks, and advice for aspiring physicists.

This episode is also available in video format on our YouTube channel - check it out! Today’s format is a little different to our usual episodes, as we’ve invited four Cavendish alumni for a panel discussion about all things physics and career development. They’ll tell us about what they learnt at the Cavendish, their natural sciences and physics background, as well as how their doctoral research in physics shaped their careers and brought them to where they are today. We’re joined by Aswathy Girija, commissioning editor at the Institute of Physics, Professor Kerstin Göpfrich, group leader at the Max Planck Institute for Medical Research, Joanne Baker, author of four popular science books and Chief Opinion Editor at Nature, and Emma Williams, professional development coach and careers expert who has a wealth of insight into not just her own journey, but those she mentors. We hope that this conversation will give you valuable insights into the many paths and opportunities for people doing physics.

Have you ever looked at the sky at night and wondered about the mysteries of the universe? When most of us are just looking at those bright stars in awe, our guest today would be searching for tiny, minuscule signals that would help unlock the mysteries of the so-called Cosmic Dawn, when the universe went from dark to bright. Eloy de Lera Acedo is an Associate Professor of Radio Cosmology and the head of the Radio Astronomy and Cosmology research group. His background in engineering and thirst of learning about the big science questions have led him to the Cavendish where he is involved in multiple international projects for new radio telescopes exploring a very, very infant universe. So, with Eloy, we talk about the universe of course and how it went from darkness to radiant, but also about childhood curiosity, choosing between technical and theoretical knowledge, and about convincing people.

Welcome back to a world of People Doing Physics! For this first episode of 2024, let us introduce you to Richard King, the Undergraduate Lab Manager at the Cavendish Laboratory. Richard oversees the practical side of the undergraduate physics course, managing the team that designs, develops, and deploys lecture demos and undergraduate experiments. A former electronic engineer, his background was in circuit design and computing before he joined the Cavendish in 2008. With Richard, we talk about how Cambridge has changed over the years, what it’s like going from fast-paced industry to the sedate world of the university, the processes involved in setting up practical work for hundreds of undergraduates, and what exactly he was doing wandering around Costa Rica with photographs of old airfields last year.

Our guest today is Emily Roe, who has recently joined us from industry to start a new role as Senior Research Laboratory Technician. Contrary to many of our previous guests, Physics is actually not her first love. What Emily was really interested in as a young mind, was geology. But it turns out field trips were not her thing, so after a degree in geology, she shifted to a lab role at the University of Durham. And shifting, she has continued to do throughout her career, jumping from one city to the next, and between University and Industry, showing off her versatility and adaptability skills in the process. She is known for her curiosity and willingness to take on new challenges, which made her accept this invitation on the podcast, but also landed her the title of “only female forklift operator” in her previous role. After nine years doing R&D in industry, she’s made yet another jump to join the Cavendish Laboratory where she now supports and assist cryostat users with their experiments and equipment. Together with Emily we talk about bridging the knowledge gap, pretty gems, culture shifts and a bit about forklifting, of course. Useful links research at HexcelITER projectCavendish website.

Long silver hair in a ponytail, a pair of Converse All Star and a Grateful Dead t-shirt… The guest sitting opposite us today in the studio is not your average Cambridge academic. But don't be fooled by his relaxed demeanour; Professor Mete Atatüre is a serious trailblazer in his field. Co-founder of the Atomic, Mesoscopic and Optical Physics Group of the Cavendish Laboratory, his ground-breaking work in quantum optics and solid-state physics has earned him accolades and respect worldwide. His experimental research group investigates light-based quantum science to enable future quantum information networks and communication, as well as new applications in sensing and magnetometry. He is an elected Fellow of the Optical Society of America, the Turkish National Science Academy, the Institute of Physics… and one of Turkish GQ Magazine’s Men of the Year 2015, amongst international actors and footballers and in recognition of his pioneering research in quantum physics! In 2018, he co-founded the successful quantum startup Nu-Quantum, and now he is looking forward to being Head of Department here at the Cavendish… His research is driven by an insatiable curiosity and motivated by a desire to see what has never been seen before, which, in the world of quantum optics, is no mean feat! Together with Mete, we talk about striking luck and grasping every opportunity, doing things outside of the clichés and the power of enthusiasm and curiosity to persevere through the times of pressure and failure.

Help us get better by taking our quick survey! Your feedback will help us understand how we can improve in the future. Thank you for your time. Here’s a question for you dear listener. What’s the link between music and physics? What is the sound of physics? Today we're diving into a fascinating world where art, science, and music intersect. Joining us in our studio are two incredible individuals who have embarked on a journey that brings together the realms of sound, physics, and human emotion. Ain Bailey is a composer and the second Cavendish Arts Science Fellow. Cavendish Arts Science creates collective encounters between art and science that explore the world, our humanity and our place in the world. Ain’s practice explores sonic autobiographies and the constellation of sounds that form individual and community identities. Her compositions are often inspired by reflections on silence and absence, feminist activism and architectural acoustics. Dr Gemma Bale is an assistant professor of Medical Therapeutics at the University of Cambridge, and the head of the Neuro Optics Lab. Sitting at the junction of engineering and physics, her team develops new, non-invasive optical devices to monitor brain metabolism in areas which traditional brain monitoring can’t. Lately, she’s been exploring the relationship between music and dementia, and it was only a matter of time before she and Ain’s worlds collided, and a conversation sparked. With Ain and Gemma, we talk about music of course, and how our brains react to it, exploring the unknown and bridging the gap between art and science.

Help us get better by taking our quick survey! Your feedback will help us understand how we can improve in the future. Thank you. This is July and the streets of Cambridge burst with sun and excitement as students let a communal sigh of relief now that the academic year is over. This is July, and the time for future students to think about what subject they might be studying when choosing to go to university. As we are welcoming hundreds of potential new students today and tomorrow for the University of Cambridge Open Days, we have invited three of our current undergraduate students to join us in the studio and talk to us, honestly and without filters, about their experience at Cambridge. Hearing directly from them may help young people thinking about studying physics in Cambridge or anywhere else, to take the leap. Misha de Fockert and Armaan Shaikh have just finished their 2nd year – here in Cambridge we call it Part IB, and Ming-Shau Liu is graduating from Cambridge after his 4th year, which, not confusingly at all, is called Part 3! All three of them, and this is just a coincidence, are students at Homerton College. With them today we talk about taking the time to reflect, imposter syndrome, building bridges and making friends for life.

On 16th June, the Cavendish Laboratory will be celebrating its 149th anniversary! To mark this occasion, we wanted to replay one of our previous episodes with one of our longest standing member of staff, Malcolm Longair. Malcolm is the memory of the Department, and his stories are fascinating, so let's jump back in with Simone, Jacob and our guest. We hope you enjoy! If you like this episode, don’t forget to rate it or leave a review on your favourite podcast app. Episode 9: With us this month is Prof. Malcolm Longair, CBE, FRS, FRSE (and Munroist). Born in Dundee, in 1941, Malcolm studied Electronic Physics at what is now the University of Dundee, but was then part of St Andrews. After this, he came down south to the Cavendish, where he completed his PhD as part of the Radio Astronomy Group, supervised by Martin Ryle. Specialising in high energy astrophysics and astrophysical cosmology, Malcolm has since been a Royal Society Exchange Visitor to the USSR; held visiting professorships at prestigious institutions around the world; been the Astronomy Royal for Scotland; Cambridge’s Jacksonian Professor of Natural Philosophy; Deputy Head and Head of the Cavendish Laboratory. He has contributed to international scientific bodies, such as NASA and ESA, and found the time to publish 22 books, over 300 scientific papers, and give hundreds of public lectures. Most recently, he has been Director of Development for the Cavendish Laboratory. In this role, he has helped modernise the Cavendish Laboratory, with the building of the Physics of Medicine building and Maxwell Centre, and the soon-to-be completed Ray Dolby Centre which will house most of the upcoming National Facility for Physics. Today, we will be talking about Malcolm’s path into Physics, what over half a century of working at the cutting edge of science has taught him, and where he sees the Cavendish laboratory going in the future.

Help us get better by taking our quick survey! Your feedback will help us understand how we can improve in the future. Thank you for your time. Joining us this month is Dr Sandro Tacchella, Assistant Professor in Extragalactic Astrophysics at the Cavendish and the nearby Kavli Institute for Cosmology. Inspired by astronomy at a young age, Sandro pursued a degree in Physics and threaded a line between the “small” scale of planetary astrophysics and the statistical world of pure cosmology. He looks at the physics underpinning the formation of galaxies and black holes, hoping to understand how these cosmic structures came to be using data from some of the most advanced telescopes on, and above, Earth. His experience of using analytical and cosmological models to determine the physical properties of galaxies is being brought to bear on data from the recently activated James Webb Space Telescope’s NIRCam instrument, and he plays a key role in projects aimed at characterising the earliest galaxies. His research has taken him around the world, from Switzerland to Korea and the US, but he has still found time to start a family and maintain a healthy work-life balance. Today, we’ll talk to him about the benefits and unique problems he faces working in astrophysics, what it has been like to do cutting-edge research on three continents, and where he sees extragalactic astrophysics going in the near future.

Help us get better by taking our quick survey! Your feedback will help us understand how we can improve in the future. Thank you for your time. This is episode 13 of People Doing Physics, the podcast from the Cavendish Laboratory at the University of Cambridge. This month marks our first birthday! One year, 12 guests, each one looking into their very own journey and connection with Physics. For this special anniversary episode, we’ve asked the head of the Cavendish Laboratory, Professor Andy Parker to take us to a building site. Not any building site though. The one, just across the road from the department’s current location, where the newest home for the Cavendish Laboratory will open in 2024. A Professor of High Energy Physics, Andy joined the Cavendish as a lecturer in 1989. He served as Deputy Head of Department for 3 years before becoming Head of Department in 2013. Who better than Andy then, who has overseen this immense project for the best part of the past 10 years, to show us around and talk about what the new building means for the future of physics in Cambridge and nationally? With him we wandered and we roamed and we talked: about particle physics, ever bigger underground tunnels, and a lost spring on the carpet.

Intro We’re joined today by Prof. Sarah Bohndiek, Professor of Biomedical Physics at the Cavendish Laboratory, Group Leader at the Cancer Research UK Cambridge Institute, and Fellow of Corpus Christi College. Born in Greenwich, Sarah found an early enthusiasm for science and went on to study Natural Sciences as an undergraduate student at Cambridge University. Drawn to interdisciplinary research, she completed a PhD in Radiation Physics at UCL’s Department of Medical Physics, looking at x-ray imaging techniques for cancer detection and working alongside biologists and chemists. Following this, Sarah moved towards optics, in order to become involved in clinical trials and took up postdoctoral positions in Cambridge and Stanford. Currently, her research group, the Vision Lab, looks to understand tumours using new medical imaging techniques, and Sarah is also particularly interested in the incredibly important process of standardising complex methods and datasets between laboratories. Alongside her research, she has championed public engagement and interdisciplinary research training, and pushes for open access, practical solutions to serious medical issues. Stay with us… Please help us get better by taking our quick survey! Your feedback will help us understand how we can improve in the future. Thank you for your time. [00:34] – Guest’s intro [02:03] – Growing up in Greenwich, fascination with Astrophysics and interest in physics [03:36] – Interest in using physics for medical application [08:35] – X-ray tomography techniques and working as part of the UK-wide consortium during PhD [12:05] – Inter-disciplinary aspect of work [13:27] – Importance of Physics of medicine building and holistic medical research approach [20:01] – In the news this month we talk about how reshaping RNA to an origami identifier opens new avenues for understanding and advancing disease diagnostics. RNA or ribonucleic acid is one of the key biological molecules that bridges our genetic information (DNA) and molecular factories (proteins). RNA has a single strand in comparison to double-stranded DNA helix. Labour-intensive approach of RNA sequencing suffers enzyme biases that causes the loss of native RNA information including RNA identity and quantity. Up until now, we could not detect RNA ‘makeup’, including its chemical modifications and overall shape. The mere order of bases in RNA could not tell us how that RNA looked. Researchers have recently developed a new method - Amplification-free RNA TargEt Multiplex Isoform Sensing (ARTEMIS) that has made possible the identification of multiple RNAs in parallel.

Intro We’re joined today by a familiar voice, Dr Paolo Molignini. Paolo will be leaving us soon, so this month we thought we would give a little insight into one of the people behind the podcast. Paolo is a postdoctoral research associate in the Theory of Condensed Matter group here at the Cavendish, bringing together elements of nonequilibrium physics, topological phases of matter, quantum optics and quantum simulation. Born in Switzerland, he gained his BSc, MSc, and PhD in Physics from ETH Zurich before taking up a postdoctoral position in the Quantum Systems Engineering group at Oxford. His research involves developing several software applications for modelling quantum systems, including UNIQORN, which applies machine learning to model systems of ultra-cold atoms. On top of this, Paolo has found time to contribute to several outreach programmes; producing a series of videos on superconductors during his time at Oxford, creating a doodle video on topological insulators for the first online Cambridge Science Festival, as well as hosting a monthly podcast looking at the people behind the physics research taking place at the Cavendish. Today, we’ll talk about his experiences growing up in southern Switzerland, his path from Civil Engineer to Physicist, the work he does as a theoretician working in an experimental laboratory, and where this will take him next. Stay with us… Please help us get better by taking our quick survey! Your feedback will help us understand how we can improve in the future. Thank you for your time.

Whether we boil water or cook pasta, a phase transition is taking place. Matter can appear in many more different phases, some of which have an inherently quantum origin, such as superfluids or ferromagnets. While some of the classical phase transitions have been known for centuries, in recent years we have started to discover and study new exciting kinds of phase transitions at the quantum level which could be soon harnessed for incredible new technologies.

Intro Joining us this month is Dr Tiffany Harte, senior research associate in the group of Prof. Ulrich Schneider here at the Cavendish Laboratory. Tiffany is an experimental physicist who works with ultracold atomic systems. These are gases of neutral elements like Rubidium or Lithium which are cooled down to incredibly low temperatures and used to probe with extreme precision fundamental properties of quantum matter which would otherwise be inaccessible in other kinds of experiments, for instance in material science. She has done research at St. Andrews, Oxford, and now Cambridge, working on all the aspects of ultracold experiments, from devising optical traps, to performing quantum simulation of exotic lattices, to engineering the next generation of cooling and transport instruments. Her latest project is very ambitious: in a consortium of 7 UK universities, she is trying to build a new type of interferometer with the ultimate goal of detecting dark matter and gravitational waves. Tiffany is also a very passionate outreach communicator. She is interested in finding new and creative ways of presenting her research, for instance by combining it with dance or devising board games inspired by the physics she sees in the lab. Her goal is to make science fun and understandable for a range of different audiences, from children to adults. In today’s episode, we’ll talk to her about the challenges of devising experiments at the limits of zero temperature, on how to find motivation when experiments break down, and how to navigate postdoc life in and out of the pandemic.

Clean and efficient energy storage technologies are essential to establishing a renewable energy infrastructure. Lithium-ion batteries are already dominant in personal electronic devices and are promising candidates for reliable grid-level storage and electric vehicles. It is very important to improve their charging rates and usable lifetimes. To do so scientist need to understand the changes occurring inside an operating battery. Researchers at the Cavendish have now developed a low-cost lab-based optical microscopy technique to study lithium-ion batteries. The key advantages of the methodology will enable further exploration of what happens when batteries fail and how to prevent it. The technique can be applied to study almost any type of battery material, making it an important piece of the puzzle in the development of next-generation batteries.

He has contributed to international scientific bodies, such as NASA and ESA, and found the time to publish 22 books, over 300 scientific papers, and give hundreds of public lectures. Most recently, he has been Director of Development for the Cavendish Laboratory. In this role, he has helped modernise the Cavendish Laboratory, with the building of the Physics of Medicine building and Maxwell Centre, and the soon-to-be completed Ray Dolby Centre which will house most of the upcoming National Facility for Physics. Today, we will be talking about Malcolm’s path into Physics, what over half a century of working at the cutting edge of science has taught him, and where he sees the Cavendish laboratory going in the future.

Atoms are the basic building blocks of every material. Combining different types of atoms naturally leads to different materials. However, it is not just the types of atoms that determine material properties, but also their arrangement.

Intro Joining us this month is Dr Diana Fusco, lecturer in biological physics here at the Cavendish Laboratory. Diana is an amazing example of what it means to have an interdisciplinary and curiosity-driven career. Her scientific journey started at the University of Milan, where as an undergraduate, she focused mainly on theoretical and statistical physics. For her doctoral studies at Duke University, she took her first big jump and pivoted to computational work in soft matter physics and proteins. After that, she switched gears yet again and embarked on a postdoc in experimental microbiology at Berkeley. Diana then joined the Department of Physics here at the Cavendish in 2018, where her growing research group now focuses on understanding bacterial biofilms and the coevolution between bacteria and viruses, employing a wide range of tools from microscopy, to theoretical modelling, to computational simulations. In today’s episode, we’ll ask her about her unusual and adventurous journey through the disciplines, the differences and intersections between theoretical and experimental sciences, and what it’s like to not just find your path, but create it.

The University of Cambridge is one of the seven international institutions, outside of South Africa, that collaborated on the international project – HERA, Hydrogen Epoch of Reionization Array. HERA is an international astronomy infrastructure, a radio telescope dedicated to observing how the first structures formed in the very early stages of the universe, as the first stars and galaxies lit up space. As per an impact study from SARAO, the University of Cambridge has been involved with the project in multiple ways. This involvement with the project, along with that by other institutions, has made a difference to the local community as well as nationally in South Africa.
