About Me:

I am a post-doctoral fellow in the Reich Laboratory at the Department of Genetics, Harvard Medical School. My research focuses on using the powerful new scientific instrument of ancient DNA — which allows us to watch humans evolve over time in a way that has never been practical before — to understand the evolution of complex and medically relevant traits. A major focus of my work is building efficient statistical and computational tools for large-scale genomic data. I completed my PhD in Mathematical Genomics and Medicine at the University of Cambridge on a Wellcome Trust fellowship where I was supervised by Richard Durbin and Chris Tyler-Smith. Prior to moving to Cambridge, I was a student at Harvard University, where I studied Biostatistics.

- This study describes the establishment and analysis of a large UK-based biobank (http://www.genesandhealth.org) to examine the impact of loss of gene function directly in humans by sequencing 3,222 individuals containing rare homozygous Loss-of-Function variants and assessing their effects on human health by combining the genetic data with lifetime electronic health records

- This study seqeunced 13 individuals from the largest and rarest of the extant great apes and examined the impact of demography on the efficacy of natural selection and in turn, its effects on the genetic mutational load.
