Yvonne Lai is the Milton E. Mohr Associate Professor of Mathematics at the University of Nebraska-Lincoln. Her PhD from University of California, Davis, was in hyperbolic geometry and geometric group theory, and she held postdoctoral positions in the Department of Mathematics and subsequently the School of Education at the University of Michigan. Her current research program, in mathematics education, seeks to improve the education of secondary mathematics teachers and early mathematics majors by bridging disciplinary perspectives from mathematics and education. She has been an investigator or co-investigator on projects receiving a total of nearly $8M in funding. Her collaborators include those from The Algebra Project, the Educational Testing Service, and the Association of Public and Land-Grant Universities. Lai currently chairs the MAA’s Committee on the Mathematical Education of Teachers. She is Vice Chair of the Board of the Mathematical Foundation of America, which oversees the Canada/USA Mathcamp for high school students, where she was previously an instructor and a student in this program. She founded the SIGMAA-MKT, an organization with over 200 members, which aims to support mathematics faculty invested in teacher education. She received, with Aron Samkoff and Keith Weber, the 2012 Janet Duffin Award from the British Society for Research into Learning Mathematics.
