Current lab members

Visiting scholars

Hugo Peyre

Hugo is a visiting scholar from Paris Diderot University (INSERM UMR 1141), France. During his PhD under the supervision of Franck Ramus at the LSCP (Cognitive Sciences and Psycholinguistics Laboratory, Paris) he examined the environmental factors influencing cognitive development during the preschool period in the French EDEN cohort. He is also consultant in child and adolescent psychiatry at the Robert Debré hospital in Paris. His current research focuses on methodological approaches using polygenic instruments within family-based designs to study the effects of prenatal environmental factors on cognitive development.

Research Associates

Tabea Schoeler

Tabea has joined the lab as a postdoctoral researcher after completing her PhD at the Institute of Psychiatry, Psychology and Neuroscience (King’s College London). During her PhD, she examined the link between cannabis use and mental health outcomes. Her current research focuses on investigating risk factors and consequences of substance use, including cannabis use. In particular, she is keen to apply more stringent statistical methods such as quasi-experimental designs and genetically informed methods to elucidate and disentangle risk effects on mental health in large epidemiological datasets.

Jessie Baldwin

Jessie is a Sir Henry Wellcome post-doctoral fellow at UCL and visiting researcher at the Social, Genetic and Developmental Psychiatry (SGDP) Centre at KCL. She completed her undergraduate degree in Psychology at the University of Warwick and master’s degree and PhD at the SGDP Centre, KCL. She then joined the CMAP Lab as a post-doctoral research associate working on an MQ-funded project on bullying victimisation and mental health. Her current research focuses on understanding the links between adverse childhood and mental health, using genetically informative designs and statistical methods to strengthen causal inference. As part of this, she is collaborating with researchers at KCL, the University of Bristol, the Karolinska Institute, and the Norwegian Institute of Public Health. She is also interested in open science and co-leads the ReproducibiliTea journal club at UCL.

Wikus Barkhuizen


Twitter: @WikusBarkhuizen

Wikus is a postdoctoral researcher at the lab. He completed his PhD at the Centre for Brain and Cognitive Development at Birkbeck on adolescent psychotic experiences such as paranoia, how these experiences overlap with mental illness, and its association with tobacco use. Wikus has a first-class BSc in Psychology from Birkbeck and an MSc from King’s College London in Early Intervention in Psychosis. He has eight years of clinical experience in the addiction sector as a practitioner and manager at substance misuse treatment services in London. He is interested in advancing our understanding of the early development of adverse mental health in the general population to ultimately improve prevention and early intervention efforts. Wikus currently uses genetically informed designs to investigate the aetiology and causal mechanisms involved in childhood ADHD and bullying victimization.

Biyao Wang

Biyao joined the lab as a post-doctoral research associate on a Nuffield-funded project. She completed her PhD in Developmental Psychopathology at University of Goettingen in Germany. During her PhD, she investigated the development relationship of general sleep problems and the transdiagnostic, general psychopathological factor of dysregulation profile. Her current research focuses on understanding the intergenerational transmission of educational achievement. By implementing data of general population samples of trios and genetically informed methods, she aims to quantify the putative causal effect of parental education on children’s educational achievement and distinguish between genetic and environmental pathways of transmission across generations.

Andrea Allegrini

Andrea joined the lab as postdoctoral researcher after completing his PhD in statistical genetics at the Social, Genetic and Developmental Psychiatry centre, King’s College London. During his PhD project Andrea focused on the application of multivariate genetic methods to better understand the (co)occurrence of complex phenotypes across child development. His research interests focus on genomic based prediction and inference, gene-environment interplay, and the developmental cooccurence of psychopathology related traits.  

He joined CMAP to investigate the intergenerational transmission of mental health problems using genetically based methods for causal inference.

Eshim joined the lab in November 2020 as a postdoctoral researcher. Prior to that, her PhD in psychiatric genetics was based at the Department of Biological Psychology at Vrije Universiteit Amsterdam. In her PhD work she used molecular genetics statistical methods to gain insight into genetic and environmental pathways of transmission of childhood mental health problems. In the CMAP lab, she will continue to investigate intergenerational transmission of mental health problems using genetically informative methods.

PhD candidates

Kai Xiang Lim 

Kai graduated from University College London (UCL) with a first class and Dean’s List award in BSc (Hons) Psychology. During his undergraduate project, his research focused on how low birth weight affects Attention-Deficit/Hyperactivity Disorder (ADHD) using twin difference designs under the supervision of Dr Jean-Baptiste Pingault and Professor Essi Viding, a paper now published in the Journal of Child Psychology and Psychiatry. He then completed an MSc in GED PP (Genes, Environment and Development in Psychiatry and Psychology) with distinction, at the SGDP (Social, Genetics and Developmental Psychiatry) centre, King’s College London. He is currently pursuing a PhD under at the same research department under the supervision of Professor Fruhling Rijsdijk and Dr. Jean-Baptiste Pingault. His PhD thesis focuses on investigating the genetic and environmental aetiologies of self-harm, particularly in the aetiological differences between suicidal and non-suicidal self-harm.

Lucy Karwatowska

Lucy received her BSc in Experimental Psychology from the University of Bristol (2012 – 2015). She collaborated with the Tobacco and Alcohol Research Group on her final-year dissertation which investigated the role of state anxiety on social evaluation learning using carbon dioxide inhalation methods. She gained a distinction for her MSc in Forensic Mental Health Research at the Institute of Psychiatry, Psychology and Neuroscience, King’s College London (2015 – 2017) and was awarded the Sheilagh Hodgins Prize for the highest dissertation mark in her cohort. She then worked at the Tavistock and Portman NHS Foundation Trust (2017 – 2018) as an Assistant Research Psychologist on an NIHR funded multi-site project investigating the effects of personalised interventions for early onset conduct problems. She started her jointly funded ESRC / BBSRC PhD Studentship in the Department of Epidemiology and Public Health, University College London in October 2018. Her current research uses causal inference designs to better understand the aetiology of conduct problems, specifically the biosocial risk factors associated with the development of antisocial behaviour. She hopes that the results from her PhD will inform future research, clinical assessments and evidence-based treatments for early-onset conduct problems.

Tracy Odigie

Tracy graduated with a Masters Distinction in MBiol Biochemistry from the University of Portsmouth (2014-2018). She underwent her masters as a placement year based at St George’s Hospital London in the Genetics Department, working on the 100,000 Genomes Project. Her masters project focused on Cancer Genomics and the Molecular Profiling of Colorectal Cancer. In September 2020, she started her jointly funded ESRC/BBSRC PhD Studentship in Biosocial Research in the Department of Epidemiology and Public Health at the University College London. Tracy is conducting a rotation project within the C-MAP laboratory, supervised by Dr Jean-Baptiste Pingault.

Emma Francis

Emma Francis is a PhD candidate carrying out a rotation project at the C-MAP lab as part of the UCL-Birkbeck MRC Doctoral Training Programme. She previously completed her undergraduate degree in Psychology at Queen’s University Belfast, and master’s degree in Psychiatric Research at the IoPPN, KCL. Emma has also previously managed the Clinical Trial Unit at South West London and St George’s NHS Trust. Her rotation project at C-MAP, supervised by Dr Jessie Baldwin and Dr Jean-Baptiste Pingault, aims to examine whether there are genetic predictors of resilience to mental health problems in the context of bullying victimisation.
