Research

current
I am currently a Post-doctoral Fellow at the Dana-Farber Cancer Institute and Department of Cell Biology, Harvard Medical School. I work in the lab of Dr. Bruce M. Spiegelman. I am investigating the regulation of adaptive thermogenesis by adipose tissue, using a combination of approaches including cell biology, biochemistry, genetics, quantitative proteomics, and computational biology. My scientific aims are centered around the identification of mechanisms that regulate adipose tissue energy expenditure. My future goal is to lead my own group in the area of energy metabolism, adipocyte biology, and mitochondrial bioenergetics.
past
I originally trained in the area of exercise and skeletal muscle physiology during my undergraduate and MSc degrees. My PhD was carried out at the University of Cambridge in the MRC Mitochondrial Biology Unit, under the supervision of Dr. Ian J. Holt (Mitochondrial Diseases). Over the course of my PhD, I used the tools of molecular biology, genetics, and biochemistry to understand the mechanisms that regulate mammalian mitochondrial DNA replication and the targeting of proteins to mitochondria via alternative translation initiation.
