Education: BS, Grove City College, 2003; PhD, Rutgers the State University of New Jersey, 2014. At SPU since 2018.

John Douglass started his career in science as a 12-year-old loading thousands of pipette tips into boxes at the University of Utah. Since then, he graduated as a biochemistry major from Grove City College and subsequently worked as a research associate in an X-ray crystallography lab. As a graduate student at Rutgers University, John became interested in metabolism and pursued projects with Dr. Judith Storch that assessed the role of fat-converting enzymes in the development of obesity. In 2014, he joined Dr. Joshua Thaler’s group at the University of Washington as a postdoctoral fellow to research how inflammation in the central nervous system impacts body weight and blood sugar.

His current research seeks to establish a better understanding of the brain in metabolic health and disease. In particular, Dr. Douglass is focused on the identifying the cellular and molecular mechanisms that link the consumption of fattening diets to the accumulation of body fat and the eventual development of type 2 diabetes. This research uses both animal and cellular models, along with a range of biochemical analyses and advanced neuroscience techniques. The ultimate goal of these projects is to aid the development of more effective treatments for obesity and diabetes.

Dr. Douglass teaches classes in the biology and chemistry departments at SPU, including human physiology, cell biology, bioethics, and general chemistry courses, as well as science-focused disciplinary research and writing courses.

Why I Teach at SPU

John Douglass, Assistant Professor of Biology

“I love the direct interaction with students. With the small class sizes, we have the ability to address questions and dive into topics as they arise. This makes for lively discussions and helps students explore the exquisite complexity of the natural world. Furthermore, the excellent faculty and top-notch facilities at SPU make is easy to involve our students in meaningful research projects that equip them with both the technical skills and scientific mindset to tackle their future challenges.”
