Sohini RamachandranManning Assistant Professor of Ecology and Evolutionary Biology
I received my bachelor's degree in Mathematical and Computational Sciences at Stanford University in 2002 — applied math, computer science, and statistics are all used extensively in my research. I received my PhD from Stanford University in Biological Sciences in 2007, working with Professor Marcus Feldman on human population genetics. I was elected to the Harvard Society of Fellows in 2007 and did postdoctoral work with John Wakeley, studying coalescent theory.
Research in the Ramachandran lab addresses problems in population genetics and evolutionary theory, using humans as a study system. Our work uses mathematical modeling, applied statistics, and computer simulations to make inferences from genetic data. We try to answer questions like: can we infer sex-biased population histories from human X-chromosomal variation? does genetic variation account for different cancer treatment outcomes? do cultural traits "mutate" more quickly than genes?
Statistical Analysis of Biological Data (BIOL 0495). This is a first course in statistics, covering probability distributions, hypothesis testing, confidence intervals, correlation and regression, and nonparametric tests. Offered spring semesters.
Human Population Genomics (BIOL 1465). This is an introduction to human genomics and the evolutionary forces that shape observed genetic variation across humans today. Topics will include the relationship among humans and other primates, human population genetics and genomics, and examples of the concomitant evolution of both cultural traits and domesticated organisms. Offered in the fall, even years.
