Thomas W. White

Thomas W. White is a Professor in the Department of Physiology and Biophysics at Stony Brook University's Renaissance School of Medicine. With a Ph.D. from Harvard University (1994), he directs an active research laboratory focused on gap junction biology and connexin proteins, investigating how mutations in these proteins lead to human diseases including deafness, skin disorders, and cataracts.

Dr. White's research program centers on understanding how intercellular communication through gap junction channels contributes to tissue homeostasis, with particular emphasis on the role of connexins in lens physiology, skin integrity, and hearing. His laboratory employs a multidisciplinary approach combining molecular biology, electrophysiology, and transgenic mouse models to investigate disease mechanisms and potential therapeutic strategies. The lab has made significant contributions to understanding how connexin mutations cause disease through both loss-of-function and gain-of-function mechanisms.

Analysis of Dr. White's recent publications (2020-2025) reveals a consistent focus on connexin channel function, particularly how mutations in connexin genes (especially Cx26 and Cx50) lead to pathological conditions through altered channel permeability and hemichannel activity. His work bridges basic science with clinical applications, exploring connections between gap junction dysfunction and conditions like Keratitis-Ichthyosis-Deafness (KID) syndrome and various forms of cataracts. A notable trend is the development of therapeutic approaches targeting abnormal hemichannel activity.

Dr. White has secured substantial research funding to support his laboratory's work on connexin biology and related diseases. His research has led to important insights about how connexin mutations cause disease, with particular emphasis on increased hemichannel activity in skin disorders. He has mentored numerous students and postdoctoral fellows who have gone on to successful careers in academia and industry.

The White laboratory maintains active collaborations with researchers studying lens physiology, dermatology, and hearing disorders. They operate specialized facilities for molecular biology, electrophysiology, and transgenic mouse modeling to investigate connexin channel function in health and disease. The lab has developed several important mouse models of connexin-related disorders that have advanced understanding of disease mechanisms.
