Theresa Guise is an award-winning photographer who uses her images to promote conservation of our planet and the animals within. The marriage of marine biology and photography started in 2006 when Theresa learned scuba diving and underwater photography. Since then, this passion has taken her world-wide to experience different microenvironments beneath the sea, which parallel her study of cancer microenvironments as a physician-scientist.

She has co-authored diving articles on Fiji, Cuba, Galapagos, Maldives and other topics with Peter de Maagt in Diver UK, Duiken, Onderwater Sport and Duikenbeld. Her photographs have appeared in The Guardian, National Geographic, Cosmopolitan, Daily Express, Scuba Diving, Live Science, RealClear, SeaUnseen, Yahoo News, MSN News, Caters News and Earth Touch; including cover images for Nature Medicine, Diver UK and Onderwater Sport.

Theresa has won awards in Underwater Photographer of the Year, Ocean Geographic, Deep Indonesia, Lens Beyond Ocean and United Nations World Ocean Day international competitions and was the featured Photographer of the week in Dive Photoguide as well as Onderwater Sport. She presents lectures on shark conservation, underwater imaging and uses underwater imagery in her scientific presentations and publications. Dr. Guise is an endocrinologist and professor at The University of Texas M.D. Anderson Cancer Center where she provides health care to cancer patients with bone disease and directs a research laboratory to study how cancer grows in bone. Her research interests in the bone microenvironment parallel her study of different microenvironments in the ocean.
