¨    Pulmonary circulation:  developed first analytical model to demonstrate that variations in flow and pressure transmission as a function of frequency depend critically upon the capacity of the pulmonary vessels to collapse and re-open, and much less upon radial expansion of already patent vessels.

 

¨    Fluid flow in collapsible tubes:  theoretical study of the fluid-wall interaction and mechanism of vessel opening and closing; application to controlled collapse of the veins, and to nonstationary flow phenomena occurring in coronary and pulmonary blood vessels.

¨    Dermal absorption of volatile vapors:  computational model for the solution of the diffusion equation for a highly anisotropic lipid bilayer medium.  Particular account taken of the variation in path length and permeability coefficients in the estimation of the penetration of toxic chemicals into and out of the skin, with eventual uptake of the chemical by the venous circulation draining from the skin into the systemic circulation.

  

¨    Controlled release drug delivery from implanted ceramic and polymeric capsules:

Mathematical modeling and computer simulations can be very effective in improving and optimizing the performance of the self-regulating release of therapeutic drugs into specific regions of the body.  development of a reliable computational design tool for predicting the resulting pharmacokinetic dose distributions as a function of time and space.  Of primary importance in such models are the time-varying effective permeability of the capsule to the various molecules composing the drug, the effective solubility and diffusion coefficients of the drug and its metabolites in the surrounding tissues and fluids and the uptake of the drug at the target organ.
