I am a PhD research scholar at Computer Science and Engineering Department of IIT Delhi. I am currently working on topics related to Spectral Hypergraph Theory, Personalized PageRank,
Machine Learning, and Local Clustering. I am being guided by Dr. Amitabha Bagchi in my academic journey.
Research Interests
My research focuses on advanced algorithms in graph theory, with a special emphasis on:
- Spectral Hypergraph Theory: This area explores the spectral properties of hypergraphs, which generalize graphs by allowing edges (hyperedges) to connect more than two vertices. The focus is on developing algorithms to efficiently analyze the structure of hypergraphs and study their eigenvalues, eigenvectors, and their application to problems such as community detection and clustering in high-dimensional data.
- Personalized PageRank: A variation of the traditional PageRank algorithm that tailors the ranking of nodes in a hypergraph based on a user's personalized query.
- Local Clustering: Methods for finding clusters or communities in large-scale hypergraphs that are locally sensitive and computationally efficient.
Honors and Awards
- I am a Venkat Padmanabhan Doctoral Fellow.
- I have been awarded the Prof. M M Chawla Gold Medal for securing highest DGPA amongst all graduates of M.Tech. in Computer Applications at IIT Delhi in year 2015.
- I obtained all India rank 19 in Gate (Mathematics) in year 2013.
- I obtained all India rank 184 in UGC + CSIR (NET + JRF) in Mathematics (December 2009).
