Dr. Tvinnereim is an Associate Professor of Cellular and Molecular Biology and the Director of the Master of Science in Biotechnology program. She was trained as an Immunologist and Microbiologist at the Medical College of Wisconsin. Dr. Tvinnereim came to the University of Texas Health Science Center at Tyler as a postdoctoral fellow in 2002 and joined the faculty in 2007. Dr. Tvinnereim is also the Director of Core Facilities and oversees common equipment used by our faculty to perform their research.

Core Facility

Dr. Tvinnereim is responsible for the operation and management of designated core facility equipment. The core facility of UT Tyler Health Science Center supports the innovative research done at UT Tyler Health Science Center by providing specialized equipment as well as expertise and training required to optimize the data obtained from this equipment. The core facility equipment includes flow cytometers, microCT scanners, flexivent ventilators, in vivo imaging systems, and aerosol exposure systems.
