Eaton received his Ph.D. at the University of California, San Diego. He did his postdoctoral training in the Department of Physiology at the University of California, Los Angeles. In 1973, he was hired as an Assistant Professor in the Department of Physiology and Biophysics at the University of Texas Medical Branch in Galveston, TX. In 1985, Eaton became a full professor and Director of the Department of Physiology and Biophysics Program at the University of Texas Medical Branch in Galveston. In 1986, Eaton moved to the Emory University Medical School in Atlanta, GA as Professor in the Department of Physiology; in 2002 Distinguished Professor. In 1995 he became Director of Graduate Studies in Cell and Developmental Biology at the Emory University Graduate School of Arts and Sciences. In 2005, Eaton became Director of the Fellowships in Research and Science Teaching (FIRST) program. In 2008, he became Department Chair at Emory. Dr. Eaton is currently regarded as one of the leaders on ion transport across excitable and epithelial cell membranes; cellular signal transduction; cellular and molecular biology of membrane transport; and nanosensor methods applied to clinical samples. Dr. Eaton has officially mentored more than 40 trainees, ranging from undergraduate summer students and predoctoral students to post-doctoral scientists at various stages of their careers. One of Dr. Eaton’s most remarkable achievements has been his role in developing and expanding Emory’s FIRST program — Fellowships in Research and Science Teaching — supported by funding from the Division of Minority Opportunities in Research (MORE) of the NIGMS. FIRST is a three year post-doctoral program that allows trainees to combine their bench research with sound training in science education, thus preparing them for a wider variety of careers. Dr. Eaton started the program with the late Dr. Robert Gunn, then Chair of Physiology at Emory, and in 2005 Dr. Eaton took over as the program director.
