David earned his doctorate under Megan Wawro. David researches relationships between undergraduate students mathematical activity and conceptual understanding, specifically focusing on how students' engagement in proof and argumentation relates to their conceptual understanding. David is also interested in developing inquiry-oriented curricula with the IOLA (Inquiry-Oriented Linear Algebra) group and helping preservice teachers learn about more effective ways to teach. David likes geometry, algebra, complex analysis, logic, puzzles, games, and game design. He has recently learned to solve the Rubik's cube and has begun a project (@cubes_art) documenting various designs he has learned to generate on larger cubes.
