Mutiara (Tia) Sondjaja


I am a Clinical Assistant Professor in the Department of Mathematics at Courant Institute of Mathematical Sciences, NYU. I completed my Ph.D. at Cornell University, where I was advised by James Renegar. I obtained my undergraduate degree in mathematics in 2008 from Harvey Mudd College.

At NYU, my primary interests and responsibilities are undergraduate teaching. I maintain active research interests in continuous optimization and in mathematical problems motivated by questions in the social sciences.
