Lauren Sugden received her doctorate in Applied Mathematics from Brown University working with Chip Lawrence, and joined the Ramachandran Lab in June 2014. She is broadly interested in how populations evolve in response to selective forces. Her current research interests involve the development of interpretable probabilistic methods for inferring beneficial mutations and genetic pathways in the human genome.
Michael Turchin received his PhD in Human Genetics from the University of Chicago while working with Matthew Stephens. Michael joined the Ramachandran Lab in October of 2017 and his research interests include human, population, and medical genetics. His current projects include methods development in multi-ethnic GWAS and pathway-based approaches. Michael has also previously worked in the labs of Jonathan Pritchard, Joel Hirschhorn, and Chip Aquadro, and was a NIH NRSA Pre-Doctoral Fellow. For more information, see see Michael's professional website.
Katherine Brunson received her doctorate in Anthropology from UCLA in 2015. She is a zooarchaeologist specializing in Chinese archaeology who has participated in numerous archaeological fieldwork projects in China and at the Maya site of Copan, Honduras. Her research focuses on the ritual aspects of animal domestication, the origins of pastoralism in East Asia, ancient DNA, bone artifact production, archaeological collections management, and digital data publishing. She is currently investigating the origins of Chinese domestic cattle and the genetic relationship between domestic cattle and the extinct East Asian wild aurochs.
Priya Nakka majored in Chemistry at Wellesley College and joined the Computational Biology PhD program and the Ramachandran Lab in June 2013. Priya's dissertation broadly presents new methods for identifying genomic elements underlying complex phenotypes and studying the inheritance of disease markers. She is currently working on identifying cases of uniparental disomy using genomic data.
Sahar Shahamatdar graduated from Brown in 2013 with an Sc.B. in Materials Science Engineering. Sahar is an MD-PhD student at Brown's Alpert Medical School, and joined the Ramachandran lab in May 2017. She is currently working on identifying germline variants that contribute to immune infiltration in tumors.
Sam Smith majored in Ecology, Evolution, and Organismal Biology at Vanderbilt University and joined the Computational Biology PhD program, and the Ramachandran Lab, in June 2017. Sam is working on developing methods for multiethnic genome-wide association studies, and for identifying shared gene subnetworks underlying multiple complex traits.
Wei Cheng graduated from Cornell University where he studied bioinformatics in Andy Clark’s lab. He is interested in studying statistical theory, and in developing computational methods for characterizing evolutionary processes using genomic data. He is currently working on developing statistics for measuring gene effect size.
Kaileigh Ahlquist received an MS from Cornell University in Plant Breeding and Genetics, studying the evolution of the MYB transcription factor family in crop species in the lab of Walter De Jong. Prior to that, Kaileigh received a BS from Reed College in Biology. Kaileigh's current focus in the Ramachandran lab is understanding and detecting balancing selection.

Dr. Yang is on the faculty at St. Jude Children's Research Hospital, in the Department of Pharmaceutical Sciences. Our collaboration centers around characterizing the evolutionary history of mutations associated with incidence and treatment outcome in acute lymphoblastic leukemia.
The Rosenberg lab at Stanford University has been a longtime collaborator with our group in studies of human population structure.
The Henn Lab at Stony Brook University investigates patterns of human genetic diversity and evolution by pairing genomic datasets with phenotypic, linguistic, and prehistoric information. We are collaborating to generate a new dataset for studying population structure on the Japanese island of Hokkaido.
The Raphael Lab at Princeton University focuses on cancer genomics. We are collaborating on methods for identifying pathways underlying common diseases using germline genetic data from cases and controls.
There are positions available for postdoctoral fellows to join the lab. Applicants must have a background in theoretical population genetics with experience analyzing data, or a quantitative background (e.g., statistics, computer science) with a desire to do research in genetics and evolutionary biology. Programming skills and proficiency in Unix-based computing environments are very desirable. Successful candidates may develop projects related to any of the lab’s research topics, or propose new projects related to the lab's interests.
Informal inquiries as well as applications (consisting of a CV, copies of relevant publications, and contact information for at least two references) should be emailed to Sohini Ramachandran.
The Ramachandran lab is recruiting prospective PhD students interested either in Ecology and Evolutionary Biology or the Center for Compuational Molecular Biology. For information, see the doctoral program pages and email Sohini Ramachandran.
Undergraduates interested in pursuing research in the lab should ideally have taken at least one semester of programming (e.g. CS150 or CS170) at Brown; familiarity with Unix utilities, Perl, and/or R is a plus. Email Sohini Ramachandran about joining the lab, and also note that UTRA can fund undergraduate researchers for a semester or the summer.
