This semester will be focused on teaching. I’m teaching calculus, applied modeling for math majors, and a graduate course on assessment for math teachers. I’m also working on some ongoing projects:
 Islander Math Circles  problem sessions for talented middle & high school math students
 DoMathTogether.com  elementary math activities for teachers and families
 STaR Fellows  a network for early career mathematics education faculty
 STPAT  teacherled reform in local middle and high school math classes
Since Fall 2010, I’ve been working in TAMUCC’s Math and Statistics Department as a tenuretrack assistant professor specializing in mathematics education. Prior to moving to Corpus Christi, my wife Melissa and I lived in Greeley, CO while I completed a Ph.D. in Educational Mathematics from the University of Northern Colorado.
