Jane BrachJane Brach began teaching at Tyler Junior College in 1988 as a part-time laboratory instructor, and became a full-time lecture instructor in 1993. Mrs. Brach earned her Bachelor of Science degree cum laude from the State University of New York at Albany. As an undergraduate, she became a member of Beta Beta Beta, the National Biological Honors Society. She attended the University of Miami at Coral Gables, Florida on a teaching assistantship stipend, where she earned her Master of Sciences degree. After moving to Texas, Mrs. Brach continued her studies by taking various post-graduate courses at Stephen F. Austin State University, the University of Texas at Tyler, and the University of Texas at Tyler Health Center.

Throughout her career at Tyler Junior College, Mrs. Brach has taught General Zoology, Biology for Non-Science Majors I & II, and currently teaches Introduction to Anatomy and Physiology (BIOL 2404). She received the Mabel Williams Chair for Teaching Excellence Award and was selected as an Honorary Member of Phi Theta Kappa.  Mrs. Brach is a member of the National Association of Biology Teachers and of the Texas Community College Teachers Association.

Mrs. Brach's philosophy mirrors that of Louis Pasteur, who said "Chance favors the prepared mind." She believes that as opportunities present themselves, students who are given adequate preparation will always find a way to excel.

Betsy OttDr. 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.

Dale CatesDale Cates, a John Tyler graduate, earned his Bachelor of Arts in Biology and his lifetime all-level Science Teacher Certification in 1976 from the University of Texas at Austin. In 1983 he earned his Masters of Science from the University of Texas at Tyler and completed 72 post-graduate hours at Texas A&M Commerce.

Mr. Cates has taught many different subjects in a variety of settings. He served as a Peace Corps volunteer in Liberia, West Africa from 1977—1979 where he taught math, science, and English. While in Liberia, he also served as a Community Development Specialist. He taught biology, physics, and chemistry at Gorman High School from 1980—1983 and at Whitehouse High School from 1983—1988. During this time he also taught biology as an adjunct instructor at Tyler Junior College. From 1988—2012, he was an instructor at Trinity Valley Community College where he taught Anatomy and Physiology I and II, Nutrition, and an on-line course in Introduction to Anatomy and Physiology. In 2012 Mr. Cates began teaching full-time at Tyler Junior College.

Dr. David Cox has been an instructor at TJC since 2013; however, he has over 35 year of teaching experience in a wide variety of biology courses and settings. He has taught : Microbiology at Texas Tech University (TTU), Texas College of Osteopathic Medicine (TCOM), Georgia Perimeter College (GPC) and now at Tyler Junior College (TJC); Anatomy and Physiology 1 & 2 at GPC and TJC; and Cell Biology at UT Tyler.

Dr. Cox received his B.S. degree in chemistry in 1970 from TTU. In 1975, he earned a M.S. degree in microbiology (minor: biochemistry) at TTU, and in 1979, he was awarded a Ph.D. in microbiology studying CO2/HCO3 assimilation by Neisseria gonorrhoeae. He subsequently took a post-doctoral position at Stanford Research Institution that focused  on the in vitro cultivation of the syphilis spirochete, Treponema pallidum. In 1981, his team was the first to grow the organism in tissue culture and he is the world authority on this technique.

In 1984, Dr. Cox took a position as an assistant professor at TCOM (currently, University of North Texas Health Science Center, Fort Worth, Texas) where he continued research on the disease syphilis. He has been a Principal Investigator on two research grants for the National Institutes of Health.  In 1989, he moved his projects to the Centers for Disease Control in Atlanta Georgia to become a Team Leader of a syphilis research group. In 2011, Dr. Cox became acting Chief of the Laboratory Reference and Research Branch of the Division of STD Prevention at CDC which provided reference and research programs for the STDs: syphilis, gonorrhoea, Chlamydia infections, and chancroid. Dr. Cox retired from CDC in 2012 after 23 years of service.

Dr. Cox has published over 45 scientific manuscripts, books, and reports. In addition to cultivation, notable contributions to the field of syphilis research include: 1. analysis of bacterial cultures by plow cytometry, 2. establishment of the lack of antigenicity of T. palladium as a pathogenic mechanism to evade hose immuse responses, and 3. development of a rapid, point-of-care diagnostic test for syphilis.

Outside interests include: gardening, wood crafts, guitar, and movies (especially the classics).
