Ramin Takloo-Bighash (born 1974) is a mathematician who works in the field of automorphic forms and Diophantine geometry and is a professor at the University of Illinois at Chicago.
Takloo-Bighash graduated from the Sharif University of Technology, where he enrolled after winning a Silver medal at the 1992 International Mathematical Olympiad.
Takloo-Bighash computed the local factors of spinor L-function attached to generic automorphic forms on the symplectic group GSp(4).
[citation needed] He has joint works with Joseph Shalika and Yuri Tschinkel on the distribution of rational points on certain group compactifications.
[citation needed] He is a co-author, with Steven J. Miller, of An Invitation To Modern Number Theory (Princeton University Press, 2006).
