Docent i matematik didaktik. Jobbar med estetik i matematik och bevis. Just nu jobbar med Curiosum, den nya science center i Umeå.
I started as a high school mathematics teacher in the mid 1990's at a private school outside of Boston. After a few years I started a PhD in mathematics education at UC Berkeley under the supervision of Alan Schoenfeld. Along the way I got a MA in mathematics from Berkeley and learned more about compactness than I ever knew I could. And along the way I met a Swedish philosopher and changed my life's course to live and work in Umeå, in the north of Sweden. My research interests have remained very rooted in mathematics. From studying how students and professors construct mathematical proofs, to investigating the nature of mathematical fit my work has gone from empirical to philosophical and has had a leaning, in recent years, to the historical. I am passionate about bringing good, high quality mathematics to schools, and one of the best parts of my job is to go out to schools and help young children think about difficult problems. Both my work as a teacher and researcher is driven by the belief that school mathematics should bear a resemblance to actual mathematical practice, both in its challenge and in its playfulness. I believe that if one has not conveyed the joy of mathematics to one's students, one has not upheld our basic responsibility as mathematics educators.
