Our Leadership Team
Catherine Harmer (she/her)

Catherine Harmer (she/her)

Director of PERL

I am an experimental psychologist who became fascinated by how antidepressants work both in terms of our brains but also our psychology. Our research looks at different treatments for depression, trying to find out what makes treatment effective, whether it is based on a medicine, a talking therapy, lifestyle change and more. By taking this approach we try to improve treatments of the future – making them more effective, faster or working for subgroups of patients that might not be helped by current treatments.

Susannah Murphy (she/her)

Susannah Murphy (she/her)

Associate Professor

Using a translational experimental medicine approach, my research assesses novel treatment approaches in humans to understand their mechanisms and predict later treatment efficacy, particularly in psychiatric treatment development. I am currently characterizing the neuropsychological effects of novel antidepressant targets and work with pharmaceutical companies to deploy this approach in drug development.

Amy Gillespie (she/her)

Amy Gillespie (she/her)

Postdoctoral Researcher

I am interested in understanding the mechanisms of psychiatric problems and their treatments. My current project investigates the effect of a novel antidepressant on cognitive processing in patients with depression, and I also coordinate a large longitudinal online study investigating emotional cognition during the pandemic.

Marieke Martens (she/her)

Marieke Martens (she/her)

Senior Postdoctoral Researcher

I started in PERL after finishing my DPhil in 2019. The main focus of my role is providing supervision and support for everything brain scanning related (MRI) in our group. I also conduct my own studies where I aim to better understand a brain area important for emotional processing called the amygdala. For this I use a brain scanner that scans with great spatial detail (7 Tesla MRI scanner). We hope these studies will help us improve our predictions of which patients may benefit from different antidepressants. More info about my current study can be found here.

Eva Periche Tomas (she/her)

Eva Periche Tomas (she/her)

Postdoctoral Researcher

I am a clinical psychologist specialising in mood and anxiety disorders. I have always been interested in how psychological and medical treatments work. My focus is on these and other mental health conditions. At PERL, I work on a multi-site study to understand how the brain controls motivation and drive. I use experimental methods to study how brain chemicals influence decision-making. I also look at how they affect the effort people put into reaching their goals.

Andreea Raslescu (she/her)

Andreea Raslescu (she/her)

Post-doctoral researcher

At PERL, I work on a Wellcome Trust-funded project exploring how the antidepressant fluoxetine (often known as Prozac) influences emotions and social interactions in young people aged 14–24. A big part of my job involves designing studies and creating tasks that help us understand emotion-related thinking and social behaviour with and without antidepressants. I work closely with a group of young advisors to make sure our methods are meaningful and easy to engage with. If you would like to know more, please feel free to contact me on my LinkedIn or email.

Riccardo De Giorgi (he/him)

Riccardo De Giorgi (he/him)

Clinical Lecturer in General Adult Psychiatry

I am interested in psychopharmacology and the evidence-based treatment of mental illness, especially mood disorders including their cognitive and physical health aspects. My research investigates biomarkers and the use of drugs with metabolic and anti-inflammatory properties to treat psychiatric disorders, integrating a variety of approaches such as experimental medicine, pharmacoepidemiology, and evidence synthesis.

I help support experimental medicine studies and carry out associated administration and project management. I very much enjoy being part of this dynamic group of researchers’ and being involved in projects that aim to better the lives of people struggling with mental health issues. I also sit on a number of Departmental People & Culture groups that are working towards achieving a more inclusive and diverse place of work.

Brennan Delattre (she/her)

Brennan Delattre (she/her)

DPhil Student

My research interests mainly sit at the intersection of social psychology and intervention science. With the SOMA study, I am presently investigating the potential benefits of cooperative, social movement-based activities (such as salsa dance!) for individuals with low mood, depression, and loneliness. We hope to translate this research to various applications within the NHS mental healthcare systems. Feel free to reach out to me on my LinkedIn or Twitter if you would like to learn more.

Ella Williams (she/her)

Ella Williams (she/her)

DPhil Student

I am interested in discovering how compounds impact various aspects of emotion and cognition, so that we might then better understand the potential mechanisms of action relevant to depression treatment. My current project is designed to assess how nitrous oxide impacts a number of psychological processes, including memory and emotional perception. Through my DPhil explorations, I hope to help inform the development of novel strategies for the treatment of depression, which may also be effective for individuals who have previously shown treatment-resistance.

Ye Wo (she/her)

Ye Wo (she/her)

DPhil Student

My research interest lies in the neurocognitive mechanism underlying the effect of SSRI treatments among young people. Currently, my study involves conducting qualitative interviews with young individuals who have encountered irritability during episodes of depression. By directly engaging with their firsthand experiences, we aim to refine our comprehension and assessment methods of irritability in depressed youth. This groundwork will lay the foundation for my future work, which further investigates the mechanisms underlying treatment effectiveness and potentially explain the differential impacts of various medications.

Aimiomode Anetor (she/her)

DPhil Student

I am currently involved in the PIPPA Study, which examines how a commercial probiotic might affect the gut microbiome, emotional processing, and cognitive functions in perimenopausal women experiencing mood and cognitive disturbances. Through my DPhil research, I aim to generate data that can inform future clinical applications of probiotics for managing perimenopausal symptoms. Before starting my DPhil, I earned my undergraduate degree in biomedical science from the University of Brighton and my Master’s degree in reproductive and developmental biology from Imperial College London.

Sagel Kundieko (she/her)

DPhil Student

I am pursuing my DPhil in Neuroscience in the Department of Psychiatry at the PERL Lab. My research explores the neural mechanisms of apathy and how they are modulated by ketamine. Using a combination of behavioural tasks and advanced neuroimaging techniques, I aim to understand how ketamine affects different domains of apathy (e.g., behavioural, cognitive, social, and emotional) and the underlying brain circuits. My previous research focused on understanding how neuroinflammation and parasitic brain infections (neurocysticercosis) affect neural excitability and network function, using electrophysiology and single-nucleus RNA sequencing techniques in mouse brain slice models.
