 I am broadly interested in theoretical computer science, with a current focus on **spectral graph algorithms** and **sublinear graph algorithms**.
 My published works concentrate on efficient approximation of **PageRank** and **Personalized PageRank** values, which are celebrated node centrality and proximity measures on graphs.
-I am expanding my research to the **[Laplacian Paradigm](https://link.springer.com/chapter/10.1007/978-3-642-13562-0_2)** **[(2.0)](https://sachdevasushant.github.io/laplacian2.0/)**, property testing, streaming algorithms, and approximate counting & sampling.
