Gavin Ralston
Foundation FellowProfessor Sir Venkatraman Ramakrishnan
Honorary Fellow; Nobel LaureateVenkatraman ‘Venki’ Ramakrishnan is a Nobel Prize-winning biologist whose many scientific contributions include his work on the atomic structure of the ribosome.
As the site within living cells where the genetic information is read to synthesise proteins from amino acids, improved understanding of the ribosome has yielded many fundamental biological insights.
He determined the atomic structure of the 30S ribosomal subunit followed by structures of the entire ribosome in many different states and in complexes with several antibiotics. More recently, he has been using electron microscopy to visualise ribosomes in action in higher organisms. This work has advanced our understanding of how the ribosome works and how antibiotics inhibit it. In the past he has also worked on histone and chromatin structure, which help us to understand how DNA is organised in cells.
Venki received the Nobel Prize in Chemistry for his work on ribosomal structure and was knighted in 2012. He is a Member of the US National Academy of Sciences, Leopoldina and EMBO, and a Foreign Member of the Indian National Science Academy. He was President of the Royal Society from November 2015 until November 2020.
Dame Esther Rantzen
Honorary FellowDame Esther Rantzen DBE CBE is a celebrated broadcaster and campaigner.
Dame Esther has appeared in more than 2,000 TV programmes including documentaries, talk shows, reality shows and quizzes as well as writing columns for The Times, Telegraph and Daily Mail, in addition to 5 books.
In 1986 Dame Esther launched Childline, the free confidential helpline for children and young people, which she chaired for nineteen years. The charity has now helped more than 4 million children and young people, both online and via the telephone. The Childline model has now been successfully copied in 150 countries around the world.
In 2012, Dame Esther launched a new confidential helpline for older people, The Silver Line Helpline, which provides information, friendship and advice 24 hours a day, every day of the year. The biggest single problem older people disclose is loneliness. Nationally launched in November 2013, it receives around 10,000 calls a week. Independently evaluated by the Centre for Social Justice in a Report entitled “When I get off the phone I feel like I belong to the human race” (a quote from a caller), and also by Anglia Ruskin University, it was found to target successfully the loneliest older people. Beside the Helpline, trained volunteers, The Silver Line Friends, provide a matched befriending service, and Silver Circles. She is Founder/President, and a Trustee of the charity, which merged with Age UK in December 2019.
After graduating from Somerville with an MA in English, she joined the BBC, first as a sound effects assistant, then a researcher. While training to be a producer/director in 1968, she became a researcher and reporter for Bernard Braden’s consumer programme “Braden’s Week”. When Braden returned to Canada in 1973, she became producer and presenter of its successor, “That’s Life!”. The show ran for 21 years and at its peak drew an audience of 22.5 million. It achieved fame for its talking dogs, Jobsworth Awards and campaigns on behalf of abused children, organ transplants, safe playgrounds, and to provide justice for consumers. Its most viewed episode featured Sir Nicholas Winton being introduced for the first time to the survivors he had saved from the Holocaust including Lord Alfred Dubs. She continues to appear on TV, and regularly contributes to “The One Show”, political and news programmes on many different topics especially those relating to broadcasting, growing old ungracefully, and to the abuse of children and older people.
A creative producer as well as a presenter, she invented the documentary series “The Big Time” which discovered Sheena Easton, created the “Children of Courage” segment of “Children in Need” and invented “Hearts of Gold” which ran for seven years, honouring unsung heroes and heroines.
In addition to being the first woman to receive the Dimbleby Award from BAFTA she has also received the Royal Television Society’s Special Judges Award for Journalism, the Snowdon Award for services to disabled people, 6 honorary doctorates, an honorary Fellowship from Somerville College, Oxford and a Lifetime Achievement Award from Women in Film and Television.
She received an OBE for Services to Broadcasting in 1991, in 2006 a CBE for Services to Children, and became a Dame Commander of the Order of the British Empire in 2015 for her work for children and older people, through Childline and The Silver Line.

Clare Rees-Zimmerman
Stipendiary Lecturer; Junior Research Fellow (Christchurch College)Academic Background
I am a chemical engineer by training, completing my undergraduate (integrated Masters) and PhD degrees at the University of Cambridge. For my MEng project, I modelled the patterns formed by blood spots during drying, under the supervision of Prof. Alex Routh. The project is important for developing accurate paper diagnostics using blood spots. I also undertook a number of industrial summer internships, including in R&D at Procter & Gamble. My PhD work examined how a mixture of differently sized particles self assembles in a thin film as it dries. I joined Christ Church as a Junior Research Fellow in October 2022.
Undergraduate Teaching
I enjoy teaching, having 4 years’ experience of small group teaching & demonstrating to Chemical Engineering undergraduates at the University of Cambridge.
Engineering (Thermofluids & Engineering in Society)
Research Interests
I am hosted by the Oxford Colloid group based in the Department of Chemistry. My current research addresses the need to make functional materials more sustainable, by using less of the expensive components, but still delivering the required properties. It does this using the science of colloidal hydrodynamics (the motion of small particles in fluid), deriving novel equations to model how mixtures of particles flow. In my fellowship, I am working on developing a new class of three-phase composite functional materials. The resulting coatings will have highly tuneable properties and I will explore the most promising applications, from reactor materials to tissue engineering. Regarding fundamental science, the required theoretical work will advance our understanding of multiphase colloidal hydrodynamics.

Chloe Riley
JCR Class OfficerHi guys, I’m Chloe (she/her) and I’m in my third year studying PPE.
My role as the JCR Class Officer entails ensuring that the college is a friendly and accessible place to people from a working class background (which to me includes all sorts of economic and cultural backgrounds, not just the traditional blue collar workers). However, as the role is still a fairly new one in college, and there’s not yet a strong class community resembling that of the BAME and LGBTQ+ students here, it’s also my job to try and establish this through running events and by always being there to try and help anyone experiencing class-related issues here.
Please contact me via Facebook (Chloe Riley) or Instagram (chlo.r4) if you have any questions or concerns, and keep an eye out on the JCR noticeboard and the somerville.class Instagram for any events I’m running!
Dr Peggie Rimmer
Foundation FellowDr Peggie Rimmer went from being the first person in her family to study at university to one of the leading voices of CERN’s computing revolution, heading a team including Professor Sir Tim Berners-Lee, inventor of the World Wide Web.
Born and raised in Liverpool, Dr Rimmer also began her academic career there. She gained the top degree in mathematics and physics from the University of Liverpool, followed by a first class Honours degree in physics. In 1961, she came to Oxford, matriculated at Lady Margaret Hall, and obtained a DPhil in nuclear physics. She then spent two years as a Junior Research Fellow at Somerville. In 1967, Dr Rimmer took up a two-year Fellowship at CERN and, relishing the company of 10,000 particle physicists, based her career there.
During her time at CERN, a fascination with the new computing equipment then emerging led Dr Rimmer to specialise in software for data acquisition and networking. Specifically, she led the group tasked with enabling standardised data collection for the multiple complex experiments being undertaken across the anarchic jumble of mini-computers, operating systems and programming languages then in use. In 1984, Tim Berners-Lee joined this team, conducting work that directly informed his Web prototype. Dr Rimmer subsequently led the CERN public relations group. Her last role prior to retirement was as Scientific Secretary to the Research Review Board.
In addition to her distinguished career, Dr Rimmer is a long-standing advocate for widening access to higher education. In 2012, she established the Peggie Rimmer Bursary for Women in Science at Somerville to enable more women to excel in STEM subjects. In 2023, she expanded this support through the Dr Peggie Rimmer Sanctuary Fund. This will transform the College’s ability to support its Sanctuary Scholars, providing those who have been displaced due to conflict, persecution or other serious human rights violations with a pathway to Oxford and support once they’re here.
