Dr. Swartz is a native of Clovis, NM. After completing dual B.S. degrees at Oklahoma State University in Biochemistry and Microbiology, he moved to Lubbock to pursue a Ph.D. from the Graduate School of Biomedical Sciences at Texas Tech University Health Sciences (TTUHSC). His dissertation work focused on using molecular biology and biochemistry techniques to create new tools for studying the transport mechanism of P-glycoprotein, an ABC Transporter that contributes to multidrug resistance. Upon completing his Ph.D., Dr. Swartz continued his research at TTUHSC through a postdoctoral fellowship funded by the American Heart Association. He also began teaching at LCU as an adjunct professor, and became a full time faculty member at LCU in the Fall of 2015.
At LCU, Dr. Swartz continues to pursue his research interests while mentoring undergraduate researchers in a variety of scientific areas including, structure and function of ABC transporters, effects of non-caloric sweeteners on living organisms, and interactions of treated wastewater with the environment. During graduate school, he met and married his wife, Dr. Lauren Swartz, who is currently a Texas Tech Family Medicine Resident.
