Professor Aghil Alaee Khangha joined the Mathematics department at Clark University in fall 2020. Before joining Clark University, he was a Black Hole Initiative fellow at Harvard University (2019-2020); a postdoctoral fellow at the Center of Mathematical Sciences and Applications at Harvard University (2018-2019); a Natural Sciences and Engineering Research Council postdoctoral fellow at the University of Toronto (2017-2018); and a Pacific Institute for the Mathematical Sciences postdoctoral fellow at the University of Alberta (2015-2017). He received his doctorate in mathematics, with distinction, from Memorial University in December 2015.


Current Teaching and Research

Professor Alaee's research focuses on geometric analysis and mathematical relativity. He investigates conjectures in general relativity — such as existence, uniqueness, and stability — and the formation of black holes using geometric analysis, which lies at the intersection of developments in differential geometry, partial differential equations, and modern physics. He has proved several geometric inequalities involving total energy, quasi-local energy, area of horizon, angular momentum, and charges of black holes.

Professor Alaee taught a variety of undergraduate mathematics courses at Clark University, Harvard University, University of Toronto, University of Alberta, and Memorial University.
