My research aims to build flexible computer networks and systems that meet the needs of the developers, operators, and users of emerging applications and networks. I take a full-stack approach, developing novel languages, compilers, algorithms, operating system designs, and hardware designs. Upcoming research topics of interest include programmable network offloads and verifiable network stack programming. I also have ongoing research on network monitoring and congestion control.

I am looking for passionate and self-motivated students with a willingness to learn. If you're interested to join my research group, please apply to the Rutgers graduate CS program and mention my name in your application. It would help if you provide a pointer to source code you have developed (e.g., a GitHub project or profile) in your application and drop me an email indicating your interest. If you're local at Rutgers, please set up a meeting slot over email.
