Alekzander Malcolm

Alekzander Malcolm

Alek Malcom is Clinical Assistant Professor of Mathematics. He received his B.Sc. in Mathematics and Physics and his Master’s in Mathematics from the University of Texas at Arlington, and his Ph.D. in Mathematics from Oklahoma State University.

Malcolm's academic interests are in complex (holomorphic) maps between real hyperspaces in complex spaces. In particular, he is interested in understanding the holomorphic automorphism groups of the spheres in n-dimensional complex space, and especially those automorphisms which generate cyclic subgroups of the automorphism group. Malcolm is also interested in mathematics education, pedagogy, and the promotion of diversity, equity, and inclusion in the classroom. 

Prior to joining NYU, Alek was Instructor of Record at Oklahoma State University.
