I am a final-year PhD student in the Department of Computer Science at Princeton University, advised by Jennifer Rexford. Before joining Princeton, I graduated summa cum laude with a B.S. in Computer Science from Saint Louis University in 2017.

As a networking researcher, I use domain-specific programming languages, efficient data structures, and optimization techniques to build practical abstractions that simplify network programming and make applications more performant by automatically resolving the tradeoff between performance and resource utilization. Currently, I'm developing a platform for identifying potential attacks on arbitary data-plane applications, as well as a platform to generate optimal configurations for data-plane algorithms.

Projects

Parasol: Automated Optimization of Parameterized Data-Plane Programs

Deploying applications on programmable data planes often requires tedious and burdensome optimization, in which a programmer must manually write an implementation, compile and test it, and then adjust their design based on their tests.

We create a framework, consisting of a sketching language and a simulation-based optimizer, that allows programmers to define general, parameterized network algorithms and automatically optimize their parameters. These parameters can represent any number of implementation decisions, and can be optimized for using arbitrary, high-level objectives.

P4All: Modular Switch Programming Under Resource Constraints

Programmable switches have very limited resources, which determine the size of data structures for a switch. Using the P4 programming languages, programmers must guess how many resources their data structures will use, and if it does not fit within the resource constraints, they must rewrite their program.

We develop a parameterized extension to P4 to allow for target-independent, generalized data structures. This platform automatically finds the optimal size of the data structure - based on a user-defined utility function - so that it compiles to any given target.

Miscellaneous

I love film photography! I shoot all of my photos on a Yashica Electro 35 GSN. You can find a selection of a few of my favorite photos here.

I also enjoy playing golf, watching Formula 1, and antiquing.
