Dr. Margaret "Betsy" Ott has taught various Biology courses for Tyler Junior College since she moved to Tyler in 1982. While she primarily teaches Human Anatomy and Physiology I & II (BIOL 2401 & BIOL 2402), Dr. Ott occasionally teaches Biology for Non-Science Majors I & II (BIOL 1408 & BIOL 1409). In the Fall of 2001 Dr. Ott began teaching the internet sections for Human Anatomy and Physiology I & II. She continuously updates her skills and awareness of the internet-based teaching arena, so that her online classes exemplify the best practices of distance education.
In 2004, Dr. Ott was elected President of the National Association of Biology Teachers.
Dr. Ott's teaching philosophy is to "make sure you get your money's worth!" She believes that the scope of Anatomy and Physiology, coupled with the critical nature of working in the Health Sciences, requires that students strive to meet a very high level of mastery in this subject. She does her best to help each student reach that high level.
Outside of teaching, Dr. Ott's interests include keeping up with environmental issues (biodiversity, conservation), mechanisms of evolution, and science education. She earned her doctoral degree in Forestry from Stephen F. Austin State University with a research area of biodiversity in plantation understory.
Dr. J. Gordon Betts, a native East Texan, received his bachelor’s degree from Stephen F. Austin State University in 1981. Midway through his undergraduate studies, he served four years in the U.S. Navy earning the rank of Aviation Electrician’s Mate Second Class.
He continued his studies at Texas A&M University receiving his Master’s degree in 1983 and Ph.D. in 1987 in Physiology of Reproduction. His doctoral dissertation was titled “Fenprostalene-Induced Luteal Regression” and was directed by Dr. David Forrest.
Dr. Betts spent the next two years as a post-doctoral research associate in the laboratory of Dr. L. Stephen Frawley at the Medical University of South Carolina. The thrust of the research was growth physiology.
He continued his post-doctoral research training for an additional two years in the laboratory of Dr. Peter J. Hansen at the University of Florida. Dr. Hansen’s laboratory concentration was in the area of reproductive immunology.
Dr. Betts accepted a position at Texas A&M – Commerce in 1991 as an Assistant Professor. Over the next six years, he taught eight different courses including Anatomy and Physiology, Immunology, Biochemistry, Endocrinology and Reproductive Physiology.
Following a few years in private industry, Dr. Betts joined the faculty at Tyler Junior College. In addition to Anatomy and Physiology, he has also taught Non-majors Biology, Introduction to Anatomy and Physiology and Introduction to Biotechnology. This last course was developed after a successful grant application submitted with other TJC faculty.
