Gail A. Cornwall

Gail A. Cornwall, Ph.D., is a Professor in the Department of Cell Biology and Biochemistry at the Texas Tech University Health Sciences Center School of Medicine. Her research bridges reproductive biology, neuroscience, and structural biochemistry, focusing on the dual roles of biological amyloids in physiological functions and disease mechanisms.

Education:

• Ph.D. in Reproductive Biology, Johns Hopkins Bloomberg School of Public Health

Dr. Cornwall's pioneering work centers on functional amyloids—protein aggregates that perform critical biological roles rather than causing pathology. Her lab investigates three interconnected research pillars: the host defense functions of amyloid matrices in the reproductive tract, the structural mechanisms of functional amyloid assembly, and the potential role of sperm amyloids as epigenetic carriers of transgenerational disease.

She discovered that the epididymal lumen contains a functional amyloid matrix that traps or kills bacteria depending on pathogen virulence, functioning as a mammalian counterpart to bacterial biofilms. Concurrently, her team explores how similar amyloid structures in the brain may regulate synaptic plasticity, and how environmental toxins induce transmissible amyloid formations in sperm that correlate with inherited disease phenotypes.

Analysis of Dr. Cornwall's 15 most recent publications (2023-2012) reveals a cohesive trajectory examining amyloid plasticity across biological systems. Her work consistently integrates structural biology (X-ray crystallography, NMR spectroscopy), transgenic models, and translational approaches to demonstrate how functional amyloids provide evolutionary advantages in host defense while maintaining the structural versatility to contribute to neurodegenerative diseases when dysregulated.

Dr. Cornwall leads a multidisciplinary laboratory employing biochemical, cell biological, and biophysical methodologies—including recombinant protein systems, gene knockout mouse models, and advanced imaging—to study amyloid dynamics. Her team maintains active collaborations with structural biologists (R. Bryan Sutton), NMR spectroscopists (Michael P. Latham, Benjamin J. Wylie), and reproductive physiologists to dissect amyloid assembly mechanisms at atomic resolution.
