Barinder Singh Banwait
Hello! Thanks for visiting!
I'm a postdoctoral fellow in Number Theory at the Interdisziplinäres Zentrum für wissenschaftliches Rechnen at Ruprecht-Karls-Universität Heidelberg in Germany.
I spend much of my time these days thinking about Galois representations associated to elliptic curves and modular newforms, and how to compute them in Sage. See my list of publications for more on my mathematical interests.
I've also recently been contributing code and data to the L-functions and modular forms database. See my Github for this and various other mathematical coding projects I've been involved in.
I can also be found hanging-out on Mathoverflow:
