About

I am a computer science PhD Candidate at Stanford University working on parallel and distributed systems, currently rotating with Fredrik Kjolstad and previously Alex Aiken. Before that, I was a software engineer at Cockroach Labs working on CockroachDB. I am fortunate to be supported by an NSF Graduate Research Fellowship.

Outside of work, you can find me lifting weights, playing tennis, cooking and (over) eating.

My resume is available here.

Research

I’m broadly interested in algorithms, computer systems, and programming languages. My recent research focuses on the intersection of these fields, in the topic of parallel computing. My research aims to present parallel algorithms for difficult problems, and to create efficient, easy to use, and scalable systems to programmers to write parallel code. I was fortunate for the opportunity to be advised by Umut Acar and to work with Sam Westrick at Carnegie Mellon on these topics. Recently, I have become interested in databases and data intensive systems, like CockroachDB.

Some projects I’ve worked on include:

  • Automatic mapping of computation and data onto heterogenous architectures
  • Memory management systems for parallel functional languages
  • Parallel algorithms for subgraph isomorphism
  • Parallel sequence data structures

Publications

  • Disentanglement in Nested-Parallel Programs, ACM SIGPLAN Symposium on Principles of Programming Languages (POPL) 2020. Sam Westrick, Rohan Yadav, Matthew Fluet, Umut A. Acar (PDF).

  • Disentanglement, Theory and Practice. Undergraduate Thesis. Rohan Yadav (PDF).

  • Brief Announcement: A Parallel Algorithm for Subgraph Isomorphism, ACM Symposium on Parallel Algorithms and Architectures (SPAA) 2019. Rohan Yadav, Umut A. Acar (PDF).

Other writings

Teaching

At Carnegie Mellon, I served as a teaching assistant for Principles of Functional Programming, and a multiple time head teaching assistant for Parallel and Sequential Algorithms and Data Structures.

Additionally, I contributed to the starting and development of the Diderot project, a new educational platform developed at Carnegie Mellon that is used by over 500 students and faculty daily. I develop and manage the cloud infrastructure for the project on an ongoing basis.
