Richard F. Hoyt, PhD

Associate Professor Emeritus, Anatomy & Neurobiology

Richard Hoyt
72 E. Concord St Instructional (L)


Dr. Hoyt is Associate Professor Emeritus of Anatomy and Neurobiology at Chobanian and Avedisian School of Medicine. Dr. Hoyt received his B.S. from Bates College and a Ph.D. in Anatomy from Harvard University and has been a member of the Department of Anatomy and Neurobiology since 1973.

He has taught and directed courses in a wide range of the biomedical sciences, including anatomy, histology, endocrinology and embryology. Dr. Hoyt has been the recipient of several teaching awards including the Stanley L. Robbins Award and Instructor of the Year in the Pre-Clinical Sciences. He is renowned for his remarkable commitment to teaching, his unique lecture style, and comprehensive knowledge of human anatomy, histology, and cellular and molecular biology.

Earlier in his career, Dr. Hoyt focused his research on the origin, development and function of endocrine cells in the lung and, with his colleagues, published over 45 research articles and chapters in the area. More recently, he has been working in collaboration with Dr. Abdul Traish overseeing a Ph.D. thesis by Monica Pessina, a graduate student in the department, on the effects of ovariectomy and steroid hormone administration on tissue morphology, hormone receptor expression and innervation in the rat vagina.
