Kevin Hwang, MD, is an internal medicine physician and professor in Houston, where he sees patients, teaches residents, and leads research and quality improvement projects. His scholarly work has appeared in leading medical journals and has been cited over 1,500 times. Dr. Hwang is board-certified in internal medicine and clinical informatics. His decades of experience in complex clinical environments have given him unique insight into both the life-saving potential and darker possibilities of modern science. Before turning to fiction, he wrote and reviewed articles on a freelance basis for general audiences. His combination of clinical expertise and writing experience led Dr. Hwang to explore fiction that examines the psychological and ethical complexities that arise when medical care meets human suffering. The Regression Strain, his debut novel, draws directly on his understanding of medicine, psychology, and what it means to face the darkest impulses of our nature.
