Biography
He did his Phd from Dalhousie and now works as Professor in UPEI, Canada. He is also the associalte Dean of the Department.
Research Interest
Dr. MacDonald works to better understand collections of matrices or operators, specifically their properties and structure. With widespread applications in all the disciplines of science, matrices are arrays of numbers and realizations of linear transformations that act on finite-dimensional spaces while operators are the infinite-dimensional analogues of matrices.
