I am a Ph.D. Candidate at the University of Nebraska-Lincoln, working with Dr. Alex Zupan and Dr. Mark Brittenham. I earned my B.A. in mathematics from Willamette University, and my M.A. in mathematics from UNL.


I am interested in low-dimensional topology and geometric topology, particularly trisections of smooth 4-manifolds. You can view my CV here
