Current Lab Members


Sohini Ramachandran PI

Sohini Ramachandran joined the faculty of Brown University in July 2010, after 3 years as a Junior Fellow at the Harvard Society of Fellows and postdoctoral fellow in Professor John Wakeley’s group at the Harvard University Department of Organismic and Evolutionary Biology. She completed her PhD in 2007 with Professor Marcus Feldman at Stanford University’s Department of Biological Sciences. Current CV and Google Scholar citations


Julia Palacios postdoctoral fellow

Julia Palacios received her doctorate in Statistics from the University of Washington studying under Vladimir Minin, and joined the Ramachandran Lab in October 2013. She also works in the Wakeley lab at Harvard. Her primary research interest is the inference of effective population size from multilocus sequence data.


Lauren Alpert Sugden postdoctoral fellow

Lauren Alpert Sugden received her doctorate in Applied Mathematics from Brown University studying under Chip Lawrence, and joined the Ramachandran Lab in June 2014. Her primary research interest is in the inference of selective sweeps from genome-wide data.


Priya Nakka graduate student

Priya Nakka majored in Chemistry at Wellesley College and joined the Computational Biology PhD program and the Ramachandran Lab in June 2013. Priya is currently working on inferring the history of selection at risk alleles associated with leukemia across multiple human ethnicities.


Stephen Rong graduate student

Stephen Rong majored in mathematics and anthropology at Washington University in St. Louis where he studied social evolution theory under David Queller. He joined the Ramachandran Lab and the Computational Biology doctoral program in Aug 2014, and though he is currently undecided about what his first research project will be, he is excited to start applying his math bio background to human population genetics.


Katie Liu '17

Katie Liu is an undergraduate concentrating in Computer Science at Brown University. She was welcomed into the Ramachandran lab in June 2015. Her main project in the lab involves working closely with Aaron and Gracie to develop software analyzing population structure, focusing on algorithm implementation. Beyond computer science, she thoroughly enjoys religious studies, psychology, lighthearted banter, and springtime. Katie has been funded by Brown University, CCMB, and an UTRA (Summer 2016).


Tyler Dae Devlin '17

Tyler is an undergraduate studying Applied Mathematics and Computational Biology at Brown University. He began work at the Ramachandran Lab in June of 2016, where he has focused on designing visualizations of population genetic data. Tyler's work during the summer of 2016 is funded by a Summer Research Assistantship under Brown's Program in Liberal Medical Education.

Collaborators

Jun J. Yang

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.

Noah A. Rosenberg

The Rosenberg lab at Stanford University has been a longtime collaborator with our group in studies of human population structure.

Brenna M. Henn

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.

Benjamin J. Raphael

The Raphael Lab at Brown University focuses on cancer genomics. We are collaborating on methods for identifying pathways underlying common diseases using germline genetic data from cases and controls.


Joining the Ramachandran Lab

Postdoctoral Fellows

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.

Graduate Students

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

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.
