DOCTORAL and POSTDOCTORAL RESEARCH

Postdoctoral Fellow,            University of California Santa Barbara                   9/2003 – present

Ÿ         Performed research in the area of systems biology with interests in optimal experiment design, systems identification, dynamical sensitivity analysis, and discrete stochastic systems; with applications in circadian rhythm, frog egg cell cycle, genetic toggle switch, enzymatic futile cycle, and apoptosis.

Ÿ         Developed iterative experiment design procedure and optimal measurement selection for iterative model development of biological systems, applied to the identification of caspase-activated apoptosis model.

Ÿ         Developed dynamical sensitivity analysis for discrete stochastic systems, applied to gene regulatory models for circadian rhythm and genetic toggle switch.

Ÿ         Developing dynamical phase sensitivity analysis for biological oscillatory systems, applied to circadian rhythm phase resetting.

Ÿ         Developing methodologies for the design of bistable genetic switch using bifurcation analysis and explicit stochastic approach, applied to enzymatic futile cycle and synthetic gene switch.

Ÿ         Actively involved in the development of sensitivity analysis tools BioSens, as part of open-source computational biology tools Bio-SPICE funded by DARPA BioComp program.

Ÿ         Actively involved in the collaborative work (UCSB, UC Berkeley, UCLA, Walter Reed, Thomas Jefferson U, Indiana U, KGI, NYU, SRI) of modeling staphylococcal enterotoxin B-apoptosis pathway in kidney cells as part of Bio-SPICE (DARPA BioCOMP Project).

 

Research Assistant,            University of Illinois at Urbana-Champaign             8/1998 – 8/2003

Ÿ         Performed research in the area of control systems with interests in robust control, optimal control, model reduction, experiment design, model identification, and hyperbolic systems; with applications in time delay systems, batch crystallization, microelectronics processing, and particulate systems.

Ÿ         Developed model reduction and robustness analysis techniques for large-scale multivariable systems with uncertain time delays.

Ÿ         Developed and applied optimal experiment design to determine kinetic parameters for nucleation and growth in batch crystallization of potassium dihydrogen-phosphate.

Ÿ         Developed and analyzed a reaction-diffusion model for transient enhanced diffusion (TED) of boron in Si during the manufacture of ultrashallow p-n junctions for advanced CMOS.

Ÿ         Employed maximum likelihood and Bayesian parameter estimation to identify the TED kinetic parameters from literature and experimental data provided by International Sematech.

Ÿ         Designed the optimal annealing procedure that achieves the optimal p-n junction thickness.

Ÿ         Developed a worst case analysis for the manufacture of ultrashallow p-n junctions to quantify the effects of model parameter uncertainties and control implementation errors.

Ÿ         Developed high resolution methods for simulating population balance equations from batch crystallization modeling with size-independent and -dependent growth rates and aggregation.

Ÿ         Developed a software package Particle Solver based on the finite volume method for simulating general particulate system dynamics described by population balance equations.
