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.

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.

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.
