Manuel Rivera

I am an Assistant Professor in the Department of Mathematics at Purdue University. 

From September 2016 to August 2019 I held a joint Research Assistant Professorship between University of Miami and CINVESTAV (Mexico City). From September 2015 to August 2016 I was a postdoc at Institut de Mathématiques de Jussieu- Paris Rive Gauche.  I completed my PhD in mathematics at CUNY Graduate Center in 2015 under the supervision of Dennis Sullivan.  From 2006-2010 I was an undergraduate at MIT.  I am originally from San Juan, Puerto Rico

My research is in algebraic topology. I am interested in understanding topological and geometric structures from the lens of homotopy theory. This had led me to think about homological and homotopical algebra, category theory, geometric topology, string topology, non-commutative geometry, symplectic topology, among other topics.

I am also interested in sharing, discussing and developing initiatives and ideas that promote research and higher education, as well as general mathematical culture, in Latin America and among underrepresented groups in academia.

My research is supported by the NSF Grant DMS 210554 Algebraic structures in topology and geometry.
