Dr. Bridges is a biologist who's research focuses on nutrient homeostasis and obesity.  His team is working on how metabolic regulation is changed with obesity and how that affects cellular metabolism.  In particular, his lab is interested in mTORC1 signaling and the connections between intracellular and extracellular signaling pathways.  Dr. Bridges did his postdoctoral training with Alan Saltiel before starting his faculty career at UTHSC in Memphis.  In 2016 he returned to Ann Arbor and the Nutritional Sciences Department in the School of Public Health.

  • BSc in Biochemistry, University of Calgary 2000
  • PhD in Biochemistry University of Calgary 2005

We are interested in the factors which cause obesity, the mechanisms by which this happens and how interventions in this pathway can alleviate obesity or its associated diseases. Our group uses a variety of model systems including cell culture, yeast, flies and mice to understand the signaling and metabolic pathways which are involved in these processes. We then use modern molecular biology, genetic and pharmacological tools to manipulate and learn more about the physiology of obesity.
