Dr. Garcia-Diaz initial research focused on epithelial electrophysiology, exploring the correlations between ion transport and electrical phenomena in leaky epithelia (intestine, gallbladder). Further work identified the ion channels responsible for the conductance of the basolateral membrane of frog skin, a classical model of tight epithelia, applying single channel recording techniques. Afterward, Dr. Garcia-Diaz’s research focused on the expression pattern of ion channels in the cochlear ganglion during neural development, and the role played by neurotrophins.
In the past twenty years Dr. Garcia-Diaz has been mostly engaged on the education of students from the School of Medicine, Physician Assistant Program, Graduate Medical Sciences (GMS), and the School of Dentistry. He is deeply involved in the MS in Medical Sciences (MAMS) program, as Director of the Human Physiology courses (PH 730 & PH 731) and academic advisor to these students. Students in the MAMS program take several first-year medical school classes to demonstrate their academic proficiency in a medical school curriculum. Since its inception, the program has been successful in identifying many students who have thrived in medical school and beyond. Dr. Garcia-Diaz also acted as a mentor in Physiology to students in the Early Medical School Selection Program (EMSSP), a partnership between BUSM and 14 undergraduate colleges, including ten historically black institutions, that facilitates acceptance into medical school of underrepresented minority students.
Role as Educator
Dr. Garcia-Diaz is a principal member of the teaching faculty in the following courses, encompassing the areas of cellular, neuro and physiological systems:
• MD 514 Dental Physiology Goldman School of Dental Medicine
• PH 730 & 731 Human Physiology A & B MAMS (GMS). Course Director
• PS 702 Physiology Physician Assistant Program
• FC 717 Physiology of Specialized Cells Graduate Medical Sciences
• MS 144 Medical Neurosciences BU School of Medicine
• MS 145M1 Cardiovascular System BU School of Medicine
• MS 145M2 Respiratory System BU School of Medicine
• MS 146M1 GI & Nutrition BU School of Medicine
• MS 146M2 Endo & Repro Systems BU School of Medicine
As Director, Dr Garcia-Diaz is involved in the daily management of the GMS Physiology courses, as well as in the development of handouts and other teaching material. A major component is the design of discussion problems and clinical cases that involve basic science concepts. Besides mentoring students in the MAMS program, Dr. Garcia-Diaz also serves as Thesis Reader for these students and in the Academic Policy Committee of the GMS Division. He was Director of the Graduate Program in the former Physiology Department and received the 2016 Educator of the Year Award in Graduate Medical Sciences.
