Jennifer Bay-Williams has been a professor at University of Louisville since 2006. She teaches courses related to mathematics teaching to preservice teachers and practicing teachers and is frequently working in elementary schools to support mathematics teaching. Prior to coming to the University of Louisville, she taught in a variety of other places – Kansas, Missouri, and Perú.

Dr. Bay-Williams is an internationally respected mathematics educator. She is a prolific author and popular speaker on topics related to effective mathematics teaching. Her work has focused on ways to ensure every student understands mathematics and develops a positive mathematics identity (i.e., feels they can do math!). Her most recent work has focused on fluency in mathematics, communicating that it is more than learning facts and algorithms, but is about being able to reason and choose appropriate strategies. Her books on fluency and on mathematics coaching are best sellers, as is her book Elementary and Middle School Mathematics: Teaching Developmentally.

Highlights of her service contributions over the past 20 years include serving as president of the Association of Mathematics Teacher Education (AMTE), on the Board of Directors for National Council of Teachers of Mathematics (NCTM) and TODOS: Mathematics for All, and the Education Advisory board for Teacher2Teacher Global.

She is married and has two children, one attending the University of Louisville and one in high school. Her hobbies include gardening, bird watching, traveling, horseback riding, and binging on TV shows.
