I am primarily interested in mathematical biology, asymptotic methods, and combining analytics with numerics to arrive at system solutions. Below are brief descriptions of my current and recent research. (COMING SOON--Click the headers for more details on each project.)
- Cancer Cell Lineage
My current research focuses on the development of a cancer lineage model including the effect of radiation-induced cellular de-differentiation. A coupled ODE population model is used to track stem, committed progenitor, and differentiation cells both with and without applied radiation, and the role of various internal feedbacks is under investigation.
- Glucose-Insulin Dynamics
I am also currently analyzing glucose-insulin dynamics via analytic solution to the Bergman-Cobelli minimal model. With the use of an expanded intermediary function, we have developed a constrained minimizing algorithm to fit patient-specific parameters for diabetes prediction. We are now testing this analytic-numeric approach on clinical data.
- Active Hearing
My thesis research centered around the development of a comprehensive model for the transduction mechanism of the mammalian cochlea. The fluid-solid interactions of the cochlea can be described by coupled PDEs; whereas, a micromechanical model has been developed to represent the outer hair cells' external forcing which influences the system nonlinearly.
