Tiago Macedo

I am an associate professor of mathematics at the Federal University of São Paulo (Unifesp), in Brazil. In the past, I have been a post-doctoral fellow at the University of Ottawa (in Canada), an assistant professor at the Federal University of Goiás (UFG-RC), and a Ph.D. student at the State University of Campinas (Unicamp).

I am currently working on a research project and teaching an undergraduate level class at Unifesp. I am also an editor of the journal Communications in Mathematics and chair of the Graduate Program in Pure and Applied Mathematics at Unifesp. More detailed information about me can be found in my Currículo Lattes and on my Github profile.

The best way to contact me is via email at tmacedo@unifesp.br.

Research

I am interested in homological algebra, representation theory, combinatorial optimization and operations research.
