Pathophysiology and Treatment of Type 2 Diabetes

Research Description

A primary mission of the Applied Metabolism & Physiology (AMP) Laboratory is âMetabolic Performanceâ. To that extent, a chief metabolic focus of our laboratory is to understand the pathophysiology of type 2 diabetes and identify novel strategies in which exercise minimizes insulin resistance for the prevention and treatment of type-2 diabetes across the lifespan. While exercise and low-fat diets combat obesity and reduce risk for chronic diseases, the optimal prescription remains unclear. Further complicating this matter is the fact that not all children and adults respond the same way to exercise, pharmacology, or bariatric surgery. Therefore, determining how to personalize exercise and diet modification for maximal metabolic fitness benefit in individuals at risk for chronic disease, and understanding the mechanisms behind such changes provides an ideal approach to promoting long-term metabolic health.
We are currently working on:
1. Tailoring exercise prescription to prevent the progression from prediabetes to type 2
diabetes in children and adults.
2. Examining how to incorporate physical activity and dietary modification to enhance the efficacy and durability of bariatric surgery on appetite and glucose regulation.
3. Determining how lifestyle modification and bariatric surgery interacts with pharmacology to regulate body weight and cardiometabolic health.
4. Gain mechanistic understanding into energy metabolism and endocrine-related inflammation by which lifestyle modification and bariatric surgery improves metabolic fitness.

Personal Statement

Dr. Steven K. Malin is an Assistant Professor in the Department of Kinesiology within the Curry School of Education and holds joint appointments in the Division of Endocrinology & Metabolism within the School of Medicine and the Robert M. Berne Cardiovascular Research Center. Dr. Malin has expertise in exercise metabolism and human nutrition. The primary focus of his clinical translational research is to prevent/treat obesity related type 2 diabetes. To accomplish this, Dr. Malin views exercise as a âdrugâ that when prescribed in an appropriate way (i.e. intensity/duration/frequency/mode) can optimize the prevention/treatment of cardiometabolic disease risk in individuals across the lifespan. His research focuses on the interaction of exercise with nutrient intake, pharmacology, and/or bariatric surgery to maximize improvements in insulin resistance, substrate oxidation, inflammation, and vascular function. Dr. Malin is the Director of the Applied Metabolism & Physiology (AMP) Laboratory and Co-Director of the Exercise Physiology Graduate Program in the Department of Kinesiology. He currently teaches undergraduate and graduate courses in Exercise Physiology and Energy Metabolism, and is an active member of the American College of Sports Medicine, American Diabetes Association, Obesity Society, and the American Physiological Society.
