TME is excited to announce our new co-editor: Sohei Yasuda! Sohei earned his M.S. in Mathematics at Purdue University and became interested in student cognition while working as a mathematics instructor at Virginia Tech. He is now an aspiring mathematics education researcher and doctoral student at UGA where he is studying student cognition, in particular how calculus students conceptualize surfaces.

As we welcome Sohei, we also want to thank outgoing editor Dru Horne for his service to The Mathematics Educator! His work and dedication to the journal will not soon be forgotten, and we hope that his future endeavors are as successful as his tenure at TME.
