As Director of Research, Richard Thiessen is setting the vision for the knowledge translation happening at the AIMS Center for Mathematics and Science Education. He is also serving the role of Senior Researcher, leading a team involved in translating research related to the development of number sequences in young children. Richard is a professor emeritus at Fresno Pacific University, where he served as Director of the Graduate Math/Science Education Program for many years. During that time he was the PI and Co-PI for Eisenhower and NSF grants, respectively. For the past 14 years, Richard has been the President of the AIMS Education Foundation. Within respect to his involvement in mathematics, one of Richard’s passions has been teaching and exploring geometry, especially three-dimensional geometry. A second passion not unrelated to the first is mechanical puzzles and in particular, three-dimensional mechanical puzzles that help students make concrete connections to geometric concepts and relationships. Dr. Thiessen received a Bachelors degree in mathematics from Friends University, a Masters in mathematics, and Ph.D. in mathematics/mathematics education from the University of Oklahoma.
