Current Research Interests:

Development of every new drug product is a 10-billion-dollar pursuit. It is time-consuming, taking about 12 years to go from early drug discovery in biology and chemistry studies to late stage activities of product manufacturing and clinical trials. Sadly, most of clinical trials still end up in failure, contributing to the skyrocketing cost in developing a drug. Motivated, we have attempted multiscale, multi-physics modeling and simulation to solve problems that are traditionally difficult and/or costly to handle in drug product development. Our efforts are also driven by the fact that computing power has kept increasing at an astonishing rate over the last two decades. Equally, thanks to the exponential growth in data storage capacity and experimental data generated from decades of high throughput screening and clinical studies, it is possible to apply predicting tools and practice data mining to design new drug molecules and products.

We have currently started several projects at this front. One is to predict protein stability under hydrodynamic stress by integrating finite element, lattice Boltzmann, and discrete element methods with molecular dynamics. Another project is to predict drug transport and absorption of parenteral products with computational fluid dynamics with pharmacokinetic modeling. Moreover, we are keenly interested in applying conceptual density functional theory in studying intermolecular interaction and mining chemical structure database to discover new molecules and structures.

In addition, we continue working on developing nanocrystal-based drug delivery systems, as well as studying molecular packing in the solid state and nucleation kinetics and mechanism.
