James M. Ntambi serves as a Professor of Biochemistry and holds the distinguished Katherine Berns Von Donk Steenbock Professorship at the University of Wisconsin-Madison in the Department of Biochemistry within the College of Agricultural and Life Sciences. His extensive research program focuses on the genetic regulation of metabolism with particular emphasis on stearoyl-CoA desaturase (SCD) enzymes and their role in metabolic diseases.
- B.Sc. and M.Sc. from Makerere University, Kampala, Uganda
- Ph.D. from Johns Hopkins University School of Medicine, Baltimore, Maryland
Dr. Ntambi's research program investigates the molecular mechanisms of lipid metabolism, particularly focusing on stearoyl-CoA desaturase (SCD) enzymes and their critical roles in obesity, insulin resistance, and associated metabolic disorders. His laboratory employs both in vitro and in vivo approaches, including genetically modified mouse models with tissue-specific SCD deficiencies, to elucidate how these enzymes regulate cellular differentiation, energy homeostasis, and disease pathogenesis. His work spans multiple systems including adipose tissue, liver, skin, and the immune system, revealing how lipid metabolism intersects with inflammation, autoimmunity, and cardiovascular function.
Analysis of Dr. Ntambi's recent publications reveals a strong focus on the role of stearoyl-CoA desaturases across multiple physiological systems. His research demonstrates how these enzymes influence metabolic health through diverse mechanisms including adipocyte differentiation, immune cell function, cardiac physiology, and neurological processes. The interdisciplinary nature of his work bridges biochemistry, molecular biology, physiology, and translational medicine, with implications for understanding and treating obesity, diabetes, cardiovascular disease, and autoimmune disorders.

Dr. Ntambi has mentored numerous graduate students and postdoctoral researchers throughout his career, including Ahmed Aljohani who completed his PhD under Ntambi's supervision. His research program has been consistently supported by competitive grants from the National Institutes of Health (NIH) and other funding agencies, enabling the development of innovative models to investigate lipid metabolism in health and disease. The Ntambi laboratory maintains active collaborations with researchers across multiple disciplines, fostering an environment of scientific discovery and training the next generation of metabolic researchers. His work has significant implications for developing therapeutic approaches targeting lipid metabolism in metabolic disorders.
Dr. Ntambi leads a vibrant research laboratory focused on metabolic biochemistry within the Department of Biochemistry at UW-Madison. His team utilizes advanced molecular, cellular, and physiological techniques to investigate the role of stearoyl-CoA desaturases in metabolic regulation. The laboratory maintains specialized mouse models with tissue-specific genetic modifications, enabling precise investigation of SCD function in different physiological contexts. Current research directions include exploring the connections between lipid metabolism and immune function, investigating the role of SCDs in neurological processes, and examining how dietary interventions affect metabolic health through SCD-mediated pathways.
