Dr. Elizabeth Borda is an Associate Professor of Biology at Texas A&M University–San Antonio, where she studies the hidden biodiversity of subterranean aquatic ecosystems in Mexico’s Yucatán Peninsula. Her research focuses on the evolutionary history and population genetics of cave-dwelling shrimp in the genus Typhlatya, species that live entirely in darkness within the region’s flooded limestone aquifer. Through DNA analyses, Dr. Borda and her collaborators have uncovered evidence that these tiny shrimp traverse vast underground passages connecting cenotes—natural sinkholes that appear isolated on the surface but are linked below ground through a complex, stratified aquifer. Her work demonstrates how these tiny crustaceans can help us understand biodiversity, connectivity, and resilience in fragile environments increasingly threatened by pollution and development. Beyond her research, Dr. Borda is passionate about science communication and mentorship. She works to make hidden ecosystems—and the lessons they hold about connection and adaptation—accessible to students and the public. Her talk draws on her scientific expertise to illuminate how even in darkness and chaos, life finds ways to endure, adapt, and connect.
