I am a master's student at New York University majoring in Scientific Computing. I received my Bachelors (with Honors) from IIIT Delhi, India majoring in Computer Science with Applied Mathematics.

Currently, I am working at the Geometric Computing Lab advised by Dr. Daniele Panozzo. I am working to optimise the Polyfem library. Previously, I was a research intern at The Mathematical Geometry Processing Lab at Freie Universit├Ąt Berlin mentored by Dr. Sunil Kumar Yadav and advised by Dr. Konrad Polthier. I worked on designing a robust and adaptive method to filter point clouds. In the summer of 2020, I was selected to be a part of the Fields Undergraduate Student Research Program 2020 (FUSRP 2020), where I worked on the problem of mechanism synthesis under the supervision of Dr. Thomas Uchida.
At IIIT Delhi, I created DECAGT, a package that provides a general, extendable software framework for discretizations of the objects and operators of exterior calculus. The concept and design of the software architecture was provided by Dr. Kaushik Kalyanaraman. I did my undergrad thesis in proposing the selfish mining attack on the multi-stage blockchain under the supervision of Dr. Donghoon Chang. I presented how the selfish mining attack can be leveraged in the multi-stage blockchain (and hence a single-stage blockchain too) and also proposed a method to modify the architecture in order to defend against the attack.

As a side project, I am currently studying and learning about the problem of surface registration using functional maps with Dr. Kaushik Kalyanaraman and Aditya Chetan.

Research Interests

My research interests particularly lie in the field of Discrete Differential Geometry and Geometry Processing.
In general, I like working with meshes and point clouds.

I am currently a member of the SIGGRAPH Research Career Development Committee. Being a part of the Professional Development team, we plan to host Conference Coffee Events at the upcoming SIGGRAPH/SIGGRAPH Asia conference each year. More details about the programme and the sign-up form is available here.
