Bryony Sheaves
Research Fellow (Somerville); Research Clinical Psychologist (Experimental Psychology); Honorary Consultant Clinical Psychologist (Oxford Health NHS Foundation Trust)My work aims to improve psychological treatments for people experiencing severe mental health problems, with a particular focus on: i) distressing voices; and, ii) sleep disruption.
In my research, I have developed a new psychological framework for understanding why voices cause distress: listening to and believing derogatory and threatening voices. The theory was built from patient interviews and tested in 591 NHS patients who hear voices. I aim to develop this into a psychological treatment to help NHS patients who hear voices to feel less emotionally affected by them.
As part of the wider Oxford Cognitive Approaches to Psychosis team I have worked on several studies which have demonstrated that sleep disruption is one contributory cause of mental health problems, including psychotic experiences. I led a pilot trial testing a sleep intervention for psychiatric inpatient wards. The treatment was feasible to deliver. The patients who received it experienced reductions in insomnia, and there were promising reductions in the duration of inpatient admissions. I have a particular interest in nightmares, their causes and the consequences for other mental health problems. Our pilot trial demonstrated that a brief CBT intervention for nightmares showed promising reductions in nightmares, insomnia and paranoia in patients experiencing psychosis.
I am an HCPC registered Clinical Psychologist and hold an honorary clinical contract with Oxford Health NHS Foundation Trust. I completed my doctorate in clinical psychology at the Institute of Psychiatry, King’s College London, following which I joined the Oxford Cognitive Approaches to Psychosis research group as part of the Wellcome Trust funded Sleep and Circadian Neuroscience Institute. I have since been funded by an NIHR Clinical Doctoral Fellowship and a Development and Skills Enhancement Award.

Dean Sheppard
Departmental LecturerI am the Departmental Lecturer in Physical & Theoretical Chemistry.
I teach Chemistry at Somerville in addition to two other colleges, Lady Margaret Hall, and St Peter’s. Previously I held Lectureships at Magdalen, Merton and New.
I studied for my MChem degree at Magdalen College (2008-2012) before moving to New College for a DPhil in Physical and Theoretical Chemistry under the supervision of Professor Stuart Mackenzie, which I completed in 2016.
My position involves teaching all aspects of the undergraduate Physical Chemistry course, from Prelims (1st Year) to Final Honours School (3rd Year). I hold tutorials for small groups of students where we discuss the lecture course material in more detail. We also meet in larger groups for problems classes to cover the more numerical aspects of each topic, and I offer thematic revision classes to prepare each group of students for their respective exams. In the Chemistry department, I provide synoptic revision lectures to all years and examine the first year Physical Chemistry Prelims paper.
My DPhil research was concerned with the photochemical spin dynamics of proteins, suggested to be the basis of the magnetic sense in some animals. It involved the development of a range of highly sensitive optical cavity-enhanced techniques to detect very small changes in reactivity caused by an external magnetic field.

Jacqueline Siu
Wellcome Trust Early Career FellowJacqueline is a Wellcome Trust Early Career Fellow in the Coles/ Dendrou Lab at the Kennedy Institute of Rheumatology.
Jacqueline’s research focus is to understand the role of early human B cell response (extrafollicular response) which has a vital role in rapid antibody production. By integrating human challenge models, ex vivo cultures, and single-cell genomics, she aims to address a fundamental immunological question about early human B cells and their impact on long-lived antibodies. Findings may facilitate tailored nextgeneration vaccination and adjuvant strategies to enhance long-term memory responses.

Professor Smith has worked with theatre companies including the Royal Shakespeare Company, National Theatre and Donmar Warehouse. In 2023, she was the Sam Wanamaker Fellow at Shakespeare’s Globe, and she has served as a consultant for TV and film, including Josie Rourke’s Mary Queen of Scots, and the BBC series ‘Shakespeare: Rise of a Genius’ (2023).
Professor Smith’s next full-length work, The First Elizabethans, is a study on Elizabethan artistic culture from architecture to music to gardens to fashion, and will be published by Penguin in 2026.
Professor Emma Smith lives in Oxford with her partner Elizabeth. She was made an Honorary Fellow of Somerville College in June 2025.
Graeme Smith
Lecturer in PhysicsI have been a lecturer at Somerville since 2001, but I first came to Oxford in 1993 to read Physics as an undergraduate (at Oriel College).
In 1997 I started work on my DPhil under the supervision of Professor Dame Carole Jordan (who retired from teaching at Somerville several years ago), having worked with her on my fourth year undergraduate project. I started teaching at Somerville directly after completing my thesis.Most of my research, including my thesis, has concerned a long-standing problem in understanding the brightness of helium emission lines seen in the ultraviolet spectrum of the solar atmosphere. My interest in astrophysics dates back to a young age, but it was rekindled by a look at Kepler’s laws in A-level physics. It was probably that spark that inspired me to apply for my first degree (although the influence of my long time love of science fiction should not be underestimated).
