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 bioenergetics. My scientific aims are centered around the identification of mechanisms that regulate adipose tissue energy expenditure. My future research will continue to focus on energy homeostasis in mammals. The primary emphasis will be directed towards understanding the relationship between mitochondrial function and the metabolic demand placed on the host in response to genetic and environmental perturbations.
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. 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.
