Vanny is a research fellow at IIT Kharagpur and is working on rational equivariant stable homotopy theory under the guidance of Prof. Samik Basu at ISI Kolkata. Apart from this, he is also a member of the Mathematical Association of Cambodia (MAC), where he has taught and helped many Cambodian students to pursue their higher studies abroad in various areas of both pure and applied mathematics.
