Current Members

Garrett Hellenthal

Garrett is currently a Professor of Statistical Genetics at UCL. He received a PhD in Statistics at the University of Washington, and subsequently worked as a post-doctoral researcher at the University of Oxford. He is currently developing and applying statistical methods to infer (i) the genetic structure of human populations (particularly in regions of Africa), (ii) historical periods when world-wide groups intermixed, for example due to invasions or migrations, and (iii) genetic loci facilitating humans' adaptations to new environments (including through methylation marks).


Alice Balard

Alice is currently working in the Hellenthal lab, developing statistical models to detect and characterise loci for which methylation marks likely are established in the early embryo, and can influence long term health in humans. After studying veterinary medicine (ENVA, Alfort, France), she transitioned to bioinformatics and evolutionary biology with a PhD in Biomedical Sciences in the FU Berlin, Germany, (Heitlinger group, HU molecular parasitology/IZW) during which she focused on the evolution of trade-offs between resistance and tolerance of the house mouse against the coccidia parasite Eimeria. She then joined the Eizaguirre lab (QMUL, London, UK) thanks to a EU Marie Skłodowska-Curie Individual Fellowship to work on the molecular epigenetic mechanisms of transgenerational transmission of immunity in stickleback fish. She then was a Teaching Fellow for a year at QMUL, in the School of Biology and Behavioural Sciences.


Nancy Bird

Nancy is a post-doctoral researcher in the group. She completed her PhD with Garrett in 2023, focusing on understanding the population structure and history of different groups across Africa, and linking this to cultural and historical factors. Her research interests include inferring population structure and ancestry in worldwide human populations, as well as understanding how humans have adapted to new environments.


Mengzi Chen

Mengzi is PhD student in the group, funded by a UCL Research Excellence Fellowhsip. Her research aims to identify adaptive genetic variants brought by the Anglo-Saxon migration and how they impact health in the UK today. Her research interests include population admixture, population migration, and ancient DNA.

Leo Speidel

Leo is currently a group leader at RIKEN, Japan’s national scientific research institute. He is part of the Interdisciplinary Theoretical and Mathematical Sciences Program (iTHEMS). Previosuly, he was a Sir Henry Wellcome fellow at UCL, Genetics Institute and the Francis Crick Institute working on Statistical and Population Genetics. He is interested in developing powerful statistical tools that utilise the rapidly growing numbers of genomes of modern and ancient people to reconstruct our shared genetic past. Our genomes can, for instance, inform us about past migrations, introgression with Neanderthals and other extinct hominids, and adaptation to environmental or lifestyle changes throughout human history. In particular, he is interested in understanding how evolutionary forces have shaped our genetic differences and how these may impact our health.

Ziyang Zia

Ziyang is a former MSc student supervised by Garrett. He is now a PhD student in Computational Biology at Cornell University. Prior to this, he obtained BSc Biological Sciences at Fudan University. He focused on genomic history of East Asia from ancient DNA perspective in his bachelor thesis (supervised by Dr. Shi Yan) and internship (supervised by Prof. Chuanchao Wang)


Maria Derakhshan

Maria is a former PhD student in the group. She now works as a business analyst at Lifescience Dynamics Limited.

Liam Quinn

Former PhD student. Liam is now post-doc in Computational and RNA Biology in Ida Moltke's group the Department of Biology at the University of Copenhagen

Dr Pongsakorn Wangkumhang

Former PhD student. Pongsakorn is now a researcher at the National Center For Genetic Engineering And Biotechnology in Thailand.

Dr Lucy Van Dorp

Lucy is a former PhD student in the group. Lucy is now a Lecturer in Microbial Genomics with us at UCL Genetics Institute, specialising in applying computational genomics methods to human-associated pathogens. Her website can be found here.

Dr Juan Camilo Chacon-Duque

Former PhD student, Camilo did his thesis on the genetic history and evolution of Latin American human populations. Currently, he is a researcher and a Marie Curie fellow at the Centre for Palaeogenetics in Stockholm (Sweden), developing data analysis strategies for characterising genomic variation in endangered and extinct species, integrating ancient, historical and modern DNA.


Dr Saioa Lopez

Former post-doc. Currently a Insight Research Analyst at Wellcome Trust, London.

Dr Sile Hu

Sile was a postdoc working on “Building a platform for genetic inference from the Genomics England data”. He was co-supervised by Prof. Simon Myers, Prof. Jonathan Marchini and Garrett Hellenthal. Sile is now working as a research Scientist in Novo Nordisk Research Center Oxford.


Dr Sam Morris

Sam is a former PhD student in the group. He is now a post-doc at the Nuffield Department of Population Health at the University of Oxford, working as a genetic epidemiologist on the China Kadoorie Biobank project.


Dr Louise Ormond

Louise is a former post-doc in the group.
