Mr Wafic Said
Foundation FellowGitalee Sarker
Fulford Junior Research Fellow; Tutor in Medicine, Lady Margaret Hall; Novo Nordisk Postdoctoral Research FellowI joined the Domingos group in the Department of Physiology, Anatomy and Genetics at the University of Oxford as a Novo Nordisk postdoctoral fellow in 2019.
My research focuses on the study of neuroimmune mechanisms underlying obesity. I use advanced molecular and genetic technologies along with computational approaches for transcriptomic profiling of sympathetic ganglia and the sympathetic neurons innervating the fat tissue. The aim is to identify the novel cellular and molecular targets that may lead to develop new tissue-specific therapies for obesity.
I completed my Ph.D. in Neuroscience at ETH Zurich in 2018. During my Ph.D., I have investigated the long-term impact of maternal overnutrition on the brain, behaviors, and metabolism. My study reveals that perinatal maternal high fat diet-induced obesogenic and addictive like phenotypes can be conserved across three generations via the paternal lineage and identifies sperm tRNA-derived small RNA as a potential epigenetic mark that partly mediates such abnormal traits to the progeny. Prior to my Ph.D., I attained an MSc in Neuroscience from the University of Bonn, Germany. I also hold a Bachelor in Medicine and Surgery (MBBS) from Dhaka Medical College, Bangladesh.

Over nine years, she has been consistently engaged in grassroots work, building community-led income generation models with rural women, smallholding farmers, and indigenous populations.
Reema’s work centers around transforming agriculture and livestock supply chains, empowering rural communities to embrace entrepreneurship through micro-enterprises. In the State of Maharashtra, she pioneered the first-ever rural women-owned food brand. This initiative not only doubled their incomes but also inspired a set of women leaders challenging the status quo regarding women’s social and economic standing in their respective villages.
Along with her efforts on the ground, Reema serves as an advisor to various non-profits and community-led organizations in India. Her role in establishing Rajasthan’s first micro camel milk dairy benefited over 3,000 camel herders, providing a sustainable source of income amidst livelihood threats due to State policies and declining camel populations. Additionally, her expertise has catalyzed the formation of Manipur’s first women-only farmer producer company (FPC), empowering over 16,000 tribal women to embrace small-scale pig farming and create value-added products from forest resources. Her responsibility in this role revolved around policy recommendations and programs aimed at enhancing technology, finance, and livelihood opportunities for women in India and Bangladesh.
She has co-authored a regional chapter on South Asia for FAO’s (The food and agriculture organization of the United Nations) report on Gender and Climate-Smart Agriculture in collaboration with the University of East Anglia (UEA, Norwich). Reema is a Presidential Award Winner in the year 2017 (awarded by the Honorable President of India and the Ministry of Woman & Child Development), recognized for bringing positive economic change for rural women in Maharashtra.
She has been featured as one of the Most powerful women in the Indian impact business in Business Today and the Forbes Magazine. Her organization, Happy Roots, has been featured as one of the successful case studies bridging gender gap in agriculture by the United Nations & The World Bank Group. Reema is also a fellow at the British Asian Trust and UnLtd India. Her passion for building more inclusive, equitable, and transformative institutions and societies, leads her to Oxford, where she seeks to deepen her inquiry through theory and practice. Reema wishes to challenge her critical thinking, both inside and outside the classroom, to solve development problems at scale. Her interest lies at the intersection of economic development, multi-dimensional equality (including gender justice and community rights) and technology. When not working, Reema indulges in the joys of traveling, exercising, and savouring a good glass of wine.

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.

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.
