“Dr. Heather Johnson, professor of mathematics education at CU Denver’s School of Education & Human Development, often rises early in the morning to collaborate with colleagues. The unusual hours come with the territory of being an internationally engaged scholar. Whether she’s Zooming with a German colleague to co-edit the theory section of the forthcoming handbook, co-leading working groups on theories in mathematics education for the Congress of the European Society for Research in Mathematics Education, teaming with a group of math theorists planning the next International Congress on Mathematics Education in Sydney, Australia, or meeting with online students who live overseas, finding the perfect time to collaborate in real time usually means navigating vast time zones.”
