Ideal Clutters, Ph.D. Dissertation.

Short bio:
I joined the Mathematics Department at LSE as an assistant professor in July 2018, and promoted to associate professor in August 2023. I obtained my PhD degree in Mathematics at the University of Waterloo under the supervision of Bertrand Guenin; the title of my dissertation was "Ideal Clutters" and the defence was in April 2018. I was a postdoctoral fellow at Carnegie Mellon University working with Gérard Cornuéjols from May 2018 to August 2019. If you need my CV, please contact me.

Short research statement:
My research expertise are broadly in Combinatorial Optimization, Integer and Linear Programming, Matroid Theory, and Graph Theory. More specifically, the focus of my research so far has been the study of Ideal Clutters, a polyhedrally defined class of objects with deep connections to the areas mentioned, and its applications. The Flowing Conjecture and the τ=2 Conjecture, and more generally the unsolved problems in the book "Combinatorial Optimization: Packing and Covering" (SIAM 2001), have shaped my research career. My research interests overlap with those of Gérard Cornuéjols and Bertrand Guenin, and the former research interests of Paul Seymour.

I have received an EPSRC New Investigator Award (2023-2026) to focus on new perspectives towards Woodall's conjecture and the generalised Berge-Fulkerson conjecture. See this page for more on the project.
