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 have been a post-doctoral researcher with PERL since 2017. I am interested in understanding how new and existing treatments for depression change emotional cognition (e.g. negative biases), and work across multiple studies. Having experienced depression myself, I am particularly passionate about this area, as well as involving people with experience of depression in designing our research. I support PERL in ensuring our research is as well-designed, inclusive, carefully run and analysed, and overall successful as possible!

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.

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)

Postdoctoral 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)

I’m always happy to discuss relevant collaborations!

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.

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.
