Lymphatic Dysfunction in Obesity: a role for iNOS

Dr. Sonial Rehal is currently a Post-Doctoral Fellow in Dr. Gregory Steinberg’s Lab. She completed her BSc. in Physiology-Pharmacology at McGill University in 2007 and received her MSc. at the University of Calgary in 2012. Sonia earned her PhD. at the University of Calgary in 2017. Her graduate training focused on lymphatic dysfunction in Inflammatory Bowel Diseases. Her postdoctoral work at Memorial Sloan Kettering in New York further explored lymphatic disease in obesity. In the Steinberg lab, she continues to investigate obesity (NASH) and atherosclerosis and the role of key growth factors in disease outcomes. 


  1. Highlight the importance of the often-overlooked role of the lymphatic system in diseases such as obesity
  2. Discuss the role of nitrosative stress via iNOS in mediated lymphatic dysfunction during obesity

Investigating the role of AMPK in regulating GDF15

Dr. Logan Townsend is currently a Post-Doctoral Fellow in Dr. Gregory Steinberg’s Lab. After completing his Kinesiology Undergrad in Lethbridge, Alberta, he moved to Ontario to do his MSc. at Wilfrid Laurier University looking at how hormonal changes throughout the menstrual cycle affects appetite. Logan completed his PhD at the University of Guelph where he looked at the interactions between tissues, like fat and the liver, in response to different stresses, like exercise and obesity.


  1. Understand basic physiology of AMPK and GDF15.
  2. Compare differences between in vivo and in vitro experiments.
