Major Achievements:

Dr. Pak has been very active in both industrial and academic research in various nano and biotechnology areas including MEMS sensors & actuators, AFM-based nanostorage, micro fluidics-base cooling device, bioMEMS lab-on-a-chip, nanopore-based DNA sequencing, and bio implant mechanics to name a few. On the more academic side, he had done a pioneering work on the fracture mechanics of piezoelectric materials. The current research topic is on the multiscale nanomechanics of defects in electronic materials which involves stress and electric field calculations in multi quantum wells and quantum dots. To have a better understanding of how defects are formed and how they affect the optoelectronic properties, molecular dynamics (MD) simulations as well as quantum mechanical calculations are performed. With the recent commerical interest for space and interplanetary explorations, his current research efforts include space radiation effects on electronic devices. To this end, Monte Carlo and radiation damage simulations are performed along with the continuum and MD analyses for gallium nitride-based high electron mobility transistors (HEMTs).
