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 postdoctoral fellow at the University of Ottawa (in Canada) and an Assistant Professor at the Federal University of Catalão (in Brazil).
I am currently working on a research project and teaching two undergraduate classes at Unifesp. I am also an editor of the journal Communications in Mathematics and a technical editor of the Journal of Non-Associative Structures. 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 mainly interested in homological algebra and representation theory. But I am also interested in combinatorial optimization and operations research.
