About Me...
My full name is Chanaka Dilshan Mapa Mudiyanselage. I am 28 years old. I am a proud Sri Lankan.
​
I am a PhD student in mathematics at RPI, currently in my third year, under the supervision of Prof. Fabian Faulstich. I previously completed my bachelor's and master's degrees in mathematics at the University of Peradeniya and RPI, where I focused on topics in graph theory (bachelor's) and quantum many-body theory (master's and doctoral). My Ph.D. thesis will be centered on the development of computational methods in quantum chemistry, particularly within localization techniques in coupled cluster theory.
​
My current research interests lie in computational quantum many-body theory, with a focus on numerical methods for solving the Schrödinger equation, electronic structure theory, and tensor-based algorithms. I am especially fascinated by the mathematical foundations behind high-performance simulations in quantum chemistry, and I aim to contribute to both theoretical and practical advancements in the field.
​
Outside of mathematics, I enjoy playing sports, mainly cricket, swimming, tennis, basketball, badminton, and carrom. I also try to stay active through regular workouts, and I’m passionate about self-improvement and personal growth.
