As my studies are research based (as in I want to research in future, and not like my current research is contributing highly to the society and I deserve a Nobel for that!), I decided it was best to create a separate page dedicated to my internships, experiences, talks and papers as to keep them together, which makes it easy to manage.

Research Experience
#

Indian Institute of Technology Guwahati

Summer Research Internship β€’ Summer 2025

Graph Theory Algorithms Complexity

Mentor

Prof. Partha Sarathi Mondal

Research Topic

Decontamination of Dynamic Network Models using External Agents

Overview

Worked on dynamic graph models and developed algorithms for monotone decontamination under changing network topologies. The work culminated in a paper accepted to CALDAM 2026 and published in the Springer LNCS proceedings.

National Institute of Technology Durgapur

Study Project β€’ Winter 2024

Fuzzy Graph Theory ODE Inventory Models

Mentors

Dr. Kartick Mohanta β€’ Prof. Anita Pal

Research Topic

Fuzzy Graphs and Dual Warehouse Inventory Models with Trade Credit

Overview

Worked on mathematical modelling of inventory systems using fuzzy graph theoretic techniques together with differential equation models involving trade credit policies.

The project served as my introduction to mathematical modelling and operations research.

Polymath Junior

Graph Theory Group Theory SageMath

Mentors

Prof. Puck Rombach β€’ Daniel Johnston β€’ Jeremy Quail

Research Topic

Asymmetric Vertex Colourings of Graphs

Overview

Worked collaboratively on asymmetric graph colourings, contributing theoretical ideas, computational experiments and manuscript preparation as part of the international Polymath Junior programme.

Undergraduate Directed Group Reading Programme

Indian Statistical Institute Bangalore β€’ 2023–2024

Knot Theory Combinatorics Teaching

Overview

Participated in advanced reading groups spanning Geometric Group Theory, Enumerative Combinatorics, Fourier Analysis and Measure Theory.

Co-taught an introductory course on Knot Theory together with Suryansh Shirbhate, preparing comprehensive handwritten lecture notes for the participants.

  • UDGRP Winter (Indian Statistical Institute, Bangalore)
    • Taken by sophomores at ISI to bridge learning topics outside the core syllabus.
