Starla Thornhill

Starla (who is shown sitting in the pilot’s seat in a model space shuttle at JSC) is studying how mixed culture, Escherichia coli and Pseudomonas aeruginosa biofilms form in microgravity. Her initial experiments are being conducted using modeled microgravity and we are planning to have an experiment on the International Space Station in the next 12-24 months.

Priscilla Pham

Priscilla is working jointly with Dhiraj Vattem and Vatsala Maitin and studying how lipid metabolism in the probiotic bacterium, Bifidobacterium longum, can control obesity using a Caenorhabditis elegans model.

Masters’ Students:

Lindsey Tristan

Lindsey is doing a course-based masters and is interested in dental school.

IMG_0080Julie Widmer

Julie just joined the lab and will be working along with Manish Kumar on genetic manipulation of Clostridium difficile and investigating the ability of this organism to live in a polymicrobial environment She just celebrated her undergraduate degree at the San Marcos River.

Undergraduate Students:

Shelbie

Shelbie Powers

Shelbie is investigating bacterial removal from biofilms. After graduating, she plans on continuing in the lab as a graduate student in the masters’ program.
