Our People

Jessica Wheeler Podnar
Director
(512) 232-5924
NMS 1.118

Jessica is a graduate of Southwest Texas State University and began her career in cell and molecular biology over 19 years ago starting at a biotech company in Reno, NV focused on telomere biology.  Her next endeavor led to the Genomic Sequencing Facility where she began as the Lab Manager in June 2010, as her role continued to grow and expand so did her responsibilities which eventually lead to the opportunity to serve as the Director. Her years of experience covers a wide range of applications, from protocol development and optimization, the many transitions in NGS platforms and preps, lab and personnel management, establishing pricing structures and policies for the facility, all the way to setting up COVID testing laboratory for the university.  She is also an active member of the Association for Biomolecular Resource Facilities, a previous member and former chair of the DNA Sequencing Research Group, and current president elect for the South Central Core Collective, SC3. 

Gabriella Huerta
Program Manager
