Research:

Staged Database Systems (click here for StageDB project page)

The StageDB project aims to redesign database management systems that exploit modern multicore hardware while exposing new opportunities for work sharing.

Modeling Environment for Software and Hardware (click here for MESH project page)

System-on-chip (SoC) designs have evolved into highly parallel and heterogeneous architectures. This trend presents new challenges when designing and modeling new systems. My masters research focused on fast and accurate modeling of asynchronous events to allow the exploration of scheduling approaches.
