Research Theme

Obesity, dyslipidemias and type 2 diabetes

  • Primary Research: Mitochondria
  • Secondary Research: Obesity, Diabetes

Key words

Mitochondria, Obesity, Diabetes, Cell Biology, Oxidative Stress

Research Program Overview

 Dr. Raha’s research focuses on understanding how obesity during pregnancy can affect the future health of the baby. He focuses on understanding the cellular communication between adipose tissue and the trophoblast cell, a type of stem cell that is central to the development of the placenta and growth and survival of the baby. Specifically he is interested in the role of the mitochondria, the energy factories of the cell, in this process. Currently, his research is directed at understanding how obesity in mother affects the development and function of the placenta using an animal model.

Knowledge Translation

Dr. Raha's knowledge translation activities are directed at helping kids understanding what happens in their bodies when the eat poorly or don’t exercise enough. He hopes that this type of information, delivered using a fun, interactive style will help to motivate and reinforce positive lifestyle changes.  Dr. Raha is also the co-founder of the Children and Youth University at McMaster (CY@Mac). This is a interactive lecture series organized for kids 8-14 years of age and designed to get them excited about a variety of science and social science topics.

Current Projects

  • Impact of maternal obesity on uterine stress.
  • Impact of maternal obesity on the development of cardiovascular dysfunction in the offspring.
  • Promote scientific learning in children through interactive scientific lectures and demonstrations.
