I teach the hiking of algorithm basics I and II and computing I and II in iCAN project, which is a new graduate certificate program to expand the participation of computer science. It is a bridge course designed for individuals who have completed their bachelor's degree in a field other than computer and want to pursue a master's degree in computer science or a career in computer science. My research interest is computer science education, which involves expanding participation in computers and designing interventions to improve students' learning outcomes.
