About

My work is primarily focused on how teachers learn about and understand the content they teach. My work has been primarily with upper elementary and middle school teachers in the areas of mathematics and computational thinking. I got into this field because of my interest in educational technology and in school reform. My work has focused on investigating how teachers understand the content they teach, how to design effective professional development to support them, and how to assess their learning. All of this is with an eye toward how students learn and how we can build better schools to support learning. I am also a certified running coach (UESCA) and personal trainer (NASM) with a particular interest in women's physiology as it relates to running -- particularly in the menopausal and perimenopausal phases. I am interested in working on projects that are focused on improving education - particularly math education, but also education more broadly. I am also interested in projects that relate to my interest in women running.
