HannaH Klawa
I am currently a Visiting Assistant Professor of Mathematics at Indiana University East. I completed my PhD in mathematics at George Mason University working under the supervision of Neil Epstein. My research is in commutative ring theory. My research has revolved around questions involving flat overrings. Most of my work falls into two categories: the preservation of properties of overrings in pullback constructions and graded analogs of domains defined in terms of properties that hold for the overrings of the domain. I have taught several undergraduate math courses in addition to working as a teaching assistant running recitations and assisting with implementing active learning activities in a graduate linear analysis course. I have also cowritten an educational research article with a group of faculty and graduate students at George Mason University.
