Research Team

Arnab Chowdry
Arnab Chowdry, PhD Platform Research & Development Manager

Dr. Chowdry joined 23andMe in January, 2009 and is primarily responsible for the technology platforms used by both the consumer product and research efforts. He and his team are responsible not only for 23andMe's various next-generation sequencing projects, but also for designing and establishing the analytical validity of the 23andMe genotyping chip. Dr. Chowdry earned his Ph.D. in Biophysics from the University of California, Berkeley where he studied computational protein design and developed protein inhibitors for breast cancer metastasis with Dr. Tracy Handel. In a previous life, Dr. Chowdry received a SmileTrain grant for his work with Dr. Simeon Boyadjiev at the Johns Hopkins Children's Hospital to determine the disease-causing loci for rare genetic diseases such as oculodentodigital dysplasia.

Brian Naughton
Brian T. Naughton, PhD Founding Scientist

Dr. Naughton joined 23andMe at its founding in 2006. Since then he has drawn on his experience in bioinformatics, statistics and genetics to analyze data, develop algorithms and translate scientific research to drive the world's first personal genome service. Among other projects, he has worked on the design of the 23andMe custom chip, and the development of tools related both to risk estimation and ancestry. Brian is a graduate of the Trinity College in Ireland where he worked with Professor Kenneth Wolfe. Brian earned his Ph.D. through the Biomedical Informatics program at Stanford University, where he worked with Professors Doug Brutlag and Serafim Batzoglou. His thesis work included novel methods for the detection of transcription factor binding sites.

Cory McLean
Cory McLean, PhD Computational Biologist

Dr. McLean joined 23andMe in 2012, and has since focused on the analysis of high-throughput sequencing data, both exome and whole genome. Prior to joining 23andMe he earned B.S. and M. Eng. degrees in computer science from MIT. He subsequently earned his Ph.D. in computer science from Stanford University, where he was a Bio-X Fellow in the lab of Gill Bejerano. Dr. McLean’s graduate work examining the role of regulatory elements in mammalian evolution and development led to first author papers in Nature, Nature Biotechnology, and Genome Research. He then joined the lab of Joseph Costello as a postdoctoral researcher at the University of California, San Francisco, where he was a Damon Runyon Cancer Research Foundation Fellow. His postdoctoral research focused on tumoral evolution in low-grade glioma and glioblastoma.

Dave Hinds
Dave Hinds, PhD Principal Scientist, Statistical Genetics

Dr. Hinds joined 23andMe in 2009 following 15 years of experience in analysis of human genetic variation and the genetics of complex traits. Dr. Hinds spent 9 years at Perlegen Sciences, where he was the lead analyst for Perlegen's genome-wide polymorphism discovery projects and contributions to the International HapMap Project, as well as developing methods for analysis of genome wide association studies. Before that, he worked for four years with Neil Risch in the Department of Genetics at Stanford University, where he developed tools for analysis of family based linkage studies. He earned his Ph.D. in Structural Biology at Stanford in 1996 as a Howard Hughes Medical Institute predoctoral fellow, where he developed methods for protein structure prediction in the laboratory of Michael Levitt. He also holds an M.Phil. in biochemistry from Cambridge University, and a B.Sc. in biological chemistry from the University of Chicago.

Eoghan Harrington
Eoghan Harrington, PhD Computational Biologist

Dr. Harrington joined 23andMe early in 2011 to integrate genome sequence data into the research and development pipeline. Prior to joining 23andMe he earned a B.A. in Human Genetics and an M.Sc. in High Performance Computing from Trinity College Dublin. He then moved to the European Molecular Biology Lab in Heidelberg, Germany to carry out his doctoral research under the supervision of Dr. Peer Bork. While there he investigated the genomics of alternative splicing and worked on protein function prediction in environmental metagenomic datasets. After earning his Ph.D. he joined the lab of Prof. David Relman at Stanford University where he secured funding from both EMBO and Human Frontiers Science Program to study the human microbiome using microbial single-cell genome sequencing and metagenomics.

Eric Durand
Eric Durand, PhD Computational Biologist

Dr. Durand joined 23andMe in 2011 and contributes to the development of features related to ancestry, including 23andMe's Neanderthal Ancestry feature. His primary interests are in the inference of ancestry and the discovery of hidden familial relationships through DNA. Before joining 23andMe, Dr. Durand was a postdoctoral researcher in the laboratory of Prof. Montgomery Slatkin at the University of California, Berkeley, where he participated in the analysis of the first draft of the Neanderthal genome. He earned a Ph.D. in population genetics and Master's degrees in applied math and the modeling of biological systems from the Grenoble Institute of Technology, France.

Joanna Mountain
Joanna L. Mountain, PhD Senior Director of Research

Dr. Mountain joined 23andMe in 2007. Since then she has contributed to the development of several research projects and a broad set of ancestry and health features. Prior to joining 23andMe, Dr. Mountain served on the faculties of the Anthropological Sciences and Genetics Departments at Stanford University. She has been awarded multiple grants from the National Science Foundation and the National Institutes of Health and has published over 50 papers in the field of human genetics. She spent two years as a Peace Corps volunteer teaching at a community school near the Kenyan coast and continues to be particularly interested in the genetic diversity of Africa. Dr. Mountain earned a Ph.D. in Genetics and a B.S. in Mathematical Sciences, both from Stanford, and conducted postdoctoral research on human evolutionary genetics at the University of California, Berkeley. Her professional interests include the patterns of genetic etiology across a broad range of human traits and diseases, the prehistory underlying human genetic diversity, and the nature of the relationship between genetic diversity and categories of race and ethnicity.

Joyce Tung
Joyce Tung, PhD Director of Research

Dr. Tung joined 23andMe in 2007. She has contributed to several of 23andMe’s research publications, and currently develops and manages research projects. After graduating from Stanford University with a B.S. in biological sciences and a minor in computer science, she performed her graduate work at the University of California, San Francisco, where she was a National Science Foundation Graduate Research Fellow in the lab of Dr. Renee Reijo Pera. At the University of California, San Francisco she focused on the genetics of egg and sperm development and human fertility. After earning her Ph.D. in Genetics, Dr. Tung returned to Stanford University for postdoctoral research in the lab of Dr. Gregory Barsh, where she studied the genetics of human and mouse pigmentation.
