Research Interests

Mathematical Modeling:

My principal research is part of a collaborative project that is focused on elucidating the mechanisms and kinetics of the Tissue Factor pathway leading to blood coagulation. This modeling entails close collaboration with medical researchers, and involves the development and analysis of both differential equation models and stochastic computer simulation models of the underlying physic-chemical processes. Our current work is focusing on two problems. One is to establish the kinetic role of rotational diffusion of membrane bound substrates that diffuse transitionally to an enzyme on the membrane. The other is to understand the kinetics of a flow reactor, this is an experimental analog of a blood vessel, consisting of a cylinder with enzymes attached to its surface through which a fluid carrying the substrate flows. In such systems, both connective and diffusional processes are involved in carrying the substrate to the enzyme attached on the tube wall. The mathematical analysis of this problem is difficult because of the boundary conditions. To explore the kinetics of such reactors for different enzyme density on the tube surface and for different substrate concentrations entering the system we are utilizing a simulation model that incorporates fluid flow, diffusion, and enzymatic kinetics.
