obtained a BSc in Physics, Mathematics and Electronics, and an MSc in Mathematics, from Central College, Bangalore University. He obtained a PhD in mathematics at the School of Mathematics of TIFR, Mumbai, where he worked on the dynamics of geodesic flow in negative curvature. He served as visiting faculty at the State University of New York, Binghamton, and was a faculty member at the Chennai Mathematical Institute before joining the TIFR Centre for Applicable Mathematics, where he is currently an Associate Professor. His main interests are in the geometric, topological and dynamical aspects of negative curvature. Outside of his research, he has translated The Man Who Knew Infinity, a biography of Srinivasa Ramanujan, into Kannada, and is the Chief Editor of the newly launched quarterly math magazine Bhāvanā.

Regularly repeating patterns are commonplace around us, on tile-laid pavements, on tapestry designs, on window grills, on rangolis and so on. Exploring newer and newer basic patterns to create novel designs has fascinated mankind for centuries. This talk begins by looking at the seemingly simple problem of tiling a flat floor by polygonal shapes and takes on a journey telling the story of how it leads to certain intriguing but as yet unresolved questions like finding out how many different convex pentagons are capable of tiling the plane. Along the way, one gets to hear about Penrose’s aperiodic tiling, the Honeycomb Conjecture and an interesting connection with the study of crystalline structures.

Kaapi with Kuriosity is a monthly public lecture series organised by the International Centre for Theoretical Sciences (ICTS-TIFR), in collaboration with the Jawaharlal Nehru Planetarium and the Visvesvaraya Industrial and Technological Museum, Bengaluru.
