Sudip Bajpeyi

Sudip Bajpeyi is a researcher affiliated with the Pennington Biomedical Research Center at the Louisiana State University (LSU) System. His work focuses on lipid metabolism in skeletal muscle, insulin sensitivity, mitochondrial function, and the interplay between physical activity and metabolic health. He has collaborated with researchers from institutions such as the University of Oslo and the Translational Research Institute for Metabolism and Diabetes.

His research bridges biochemistry, endocrinology, and exercise physiology, particularly in contexts like Type 2 Diabetes Mellitus (T2DM) and the 'athlete's paradox'—a phenomenon where endurance athletes exhibit high intramyocellular lipid (IMCL) content despite being insulin-sensitive. He utilizes techniques such as immunohistochemistry, gas chromatography (GC-FID), and mass spectrometry (LC-ESI-MS/MS) to quantify lipid metabolites like ceramides and diacylglycerols.

• Key findings: Cultured myotubes from physically active donors showed higher lipid content and mitochondrial mass compared to sedentary individuals, correlating with in vivo measures like ATPmax and insulin sensitivity.
• Lipid metabolites: Ceramides and DAGs in myotubes were inversely linked to insulin sensitivity and mitochondrial function, highlighting their role in insulin resistance.
