Project Team


Hee-Joon Kim,Ph.D., leads the curriculum design in MPACT. She is a mathematics education researcher who designs curriculum materials and studies the mathematical knowledge essential for teaching mathematics. Formally trained as a secondary math teacher in Korea and as an education researcher in the U.S., she has engaged in designing and studying the use of innovative curriculum materials integrated with dynamic representation technology to deepen student understanding of mathematical concepts and broaden participation of underserved students in STEM+C for 10 years. For fun, she likes cooking, decorating foods, and making fun (and tasty) lunchboxes. She received her B.S. in Mathematics at Ewha Womans University in Korea and Ph.D. in Mathematics Education at the University of Texas at Austin.

Jennifer Knudsen is MPACT’s director. She is a veteran mathematics educator who works at the intersection of research and design. A former high school math and computer science teacher, she has designed and implemented innovative, technology-rich curriculum and teacher professional development, all focused on increasing the opportunity to learn high-level content for historically marginalized students. She has helped students learn through pure mathematics and through real-world based projects. Her approaches bring playfulness to professional development and the classroom. She also does watercolor and collage for the fun of it. Knudsen is a graduate of the Evergreen State College, where she came to love both mathematics and learning.

Teresa Lara-Meloy, leads MPACT’s professional development activities and is part of the curriculum design team.  As a former educator and member of a family of educators, she is committed to supporting teacher in any way she can. She has over 20 years of experience in designing experiences for students and teachers integrating curriculum, technology, and professional development. She has an Ed.M. from the Harvard Graduate School of Education (Technology in Learning). For fun, she spends lot of time with her children mathematizing and making art together. And, in another pre-pandemic life, she loved traveling.


Ken Rafanan leads MPACT’s mentoring outreach and is part of the curriculum design team. He brings over 15 years of experience as a mathematics education researcher. Ken’s work focuses on the design of learning activity systems integrating teacher professional development, curriculum, assessment, and technology aimed at enhancing learning of critical mathematics. Ken enjoys coaching baseball, cooking, and spending time with his wife, son and their two cats. He received his masters degree from the Stanford University Graduate School of Education (Learning, Design and Technology) working with Professors Shelley Goldman and Jim Greeno (now emeritus).

Harriette S. Stevens, Ed.D., is a mathematics educator with experience teaching in urban secondary schools and community colleges. For over 30 years she directed mathematics professional development programs for K-12 teachers at the University of California’s Lawrence Hall of Science, with a focus on bridging research and best practices in teaching and learning mathematics. She has collaborated with diverse urban school districts, including Oakland, San Francisco, and San Mateo. She has a B.A. in Applied Mathematics and an M.A. in education, with a concentration in mathematics from the University of Kansas; a doctorate in curriculum and instruction, from the University of San Francisco; and continuing education coursework from Columbia University, New York City. Throughout her career, she has focused on helping teachers strengthen their knowledge of mathematics in ways that encourage students to problem solve and communicate their understanding of mathematics. These experiences have fueled her passion for increasing the achievement of underrepresented students in STEM-related fields. In addition to her professional practice, Harriette enjoys reading, crocheting and cultivating her urban garden as a habitat for bees, butterflies and hummingbirds.
