About

I am currently an Assistant Teaching Professor at Northeastern University in the Khoury College of Computer Sciences. My research and teaching interests are in Computer Systems, program analysis, and graphics. I care about all things related to performance engineering.

I completed my Ph.D. at Tufts University in the Redline Research Group in 2017. My Ph.D. thesis advisor was Samuel Z. Guyer. I completed my Masters degree in Computer Science in 2013 at Tufts University, and my Bachelors in Computers Science Engineering at The Ohio State University in 2011.

News


I am serving on the PLDI 2020 Artifacts Committee

I will be presenting at EuroLLVM 2020 a tutorial on common compiler optimizations.

I have given a talk on an Introduction to Cache Oblivious Algorithms at ACCU 2019 Belfast.

I will be serving on the EuroLLVM 2020 program committee in Paris, France this year.

Research


My research interest is in analyzing the performance of real time systems. Typically applications where performance matters are in the domains of game engines, computer graphics, and intensive system applications. I perform my research by building static analysis, dynamic analysis, and software visualization tools. [Google Scholar Link]

Current Northeastern students wanting to get involved with my research can browse various Sidequests to see if there are mutually interesting projects.

Computer Systems

Research Currently I am working with several students on building program analysis tools for working with data structures. Another undergraduate student is working on building tools to monitor the performance of programs.

Program Analysis

Research Currently a graduate student and I are investigating a program analysis technique for monitoring threads in C and C++ programs.
