PRINCIPAL INVESTIGATOR
Jason T. George, MD, PhD
Texas A&M | Orchid | Google Scholar
Dr. George is an Assistant Professor in the Department of Biomedical Engineering at Texas A&M University. His research focuses on developing mathematical models to better understand complex biological systems. His group utilizes techniques from biophysics, probability, and stochastic process theory to model the effects of randomness on system dynamical response. In immunology, he has developed random energy models of the interaction between T cells and antigens with applications directed at understanding the effects of T cell selection on the recognition of viral and tumor-associated antigens. These foundational modeling efforts have motivated a machine learning-based structural biophysical characterization of the T cell-antigen interaction, with the goal of accurate T cell specificity prediction at the level of the human immune repertoire.
His work in cancer modeling tracks the co-evolution between an evolving cancer population and recognizing T cell repertoire. Applications include the development of enhanced cancer incidence models that incorporate immune function and the prediction of optimized treatment strategies. His group has worked to pioneer a class of mathematical models that frame cancer progression as a stochastic optimal decision-process, through which the extent of ‘adaptive’ cancer evasion strategies and disease aggressiveness can be more precisely understood. The group actively emphasizes experimental and clinical collaboration for validation and model-driven identification of improved therapeutic strategies.
Dr. George earned a B.S. in Biomedical Engineering and B.A. in Mathematics at Texas A&M University. He completed his M.D. at Baylor College of Medicine and Ph.D. in Bioengineering at Rice University under Dr. Herbert Levine. He completed his postdoctoral training under Dr. José Onuchic. In the classroom, he is passionate about identifying and tackling problems in medicine and biomedical engineering via detailed application of mathematical theory.
POSTDOCTORAL FELLOWS
Pujan Shrestha, PhD
Pujan is interested in probability theory, stochastic processes and their application in understanding cancer. He has previously worked on the theory of anticipating stochastic calculus and large deviation principles. He develops stochastic control models of cancer progression, tumor-immune interaction and immune mediated cellular dormancy. His areas of interest include mathematical biology, probability theory, stochastic processes, optimization, numerical analysis, and differential equations.
Being born and raised in Nepal, Pujan loves hiking and the outdoors. He loves road trips and driving around the US. He recommends the Blue Ridge Parkway drive around late October. Since moving to Houston, Pujan has had a great time exploring the sights, sounds, and dining options that the city has to offer.
