Assoc. Prof. Hyunyi Jung, Ph.D
Texas A&M University
Her research explores mathematics education as a humanizing practice, drawing on the work of Freire (1970) to emphasize the connection between learners’ well-being and the sociohistorical contexts that shape their meaningful experiences in mathematics. She is committed to fostering a more accessible and equitable learning environment for both students and teachers, with a focus on the design, implementation, and evaluation of inclusive mathematics curricula and pedagogical approaches.A central focus of her research is the implementation of mathematical modeling, which empowers students to integrate mathematical concepts with their personal experiences to analyze real-world situations and make informed decisions. Through mathematics sessions, summer camps, and after-school programs, she provides opportunities for students, teachers, and community members to engage in equitable mathematical modeling and problem-solving.Her research methodology is grounded in multi-tiered design-based research (Lesh & Kelly, 2000), enabling her to delve into culturally sustaining practices. It also identifies theoretical perspectives related to instructional design, implementation, and discourse that emerge from the application of mathematical modeling and STEM problem-solving.
Dr. Hyunyi Jung has dedicated her efforts to creating inclusive learning environments for students and teachers, with a focus on the design, implementation, and analysis of mathematical modeling curricula and humanizing pedagogical approaches. She frequently facilitates mathematics sessions, summer camps, and after-school programs, providing students, teachers, and community members with opportunities to engage in equitable mathematical modeling and problem-solving. Her contributions and passion for teaching were recognized at the University of Florida, where she received the Diane E. Haines Teaching Excellence Award. She has also been honored with the Early Career Award from the Association of Mathematics Teacher Educators, the largest professional organization devoted to the improvement of mathematics teacher education. She has been invited to present her research on humanizing practices for mathematical modeling through a keynote at international symposia and conferences. She has collaborated with students, teachers, and community members to establish collaborative mathematical modeling learning spaces and develop free mathematics programs and resources for marginalized students and their communities.

Prof. Jein-Shan Chen, Ph.D.
Department of Mathematics, National Taiwan Normal University
He is currently a Professor at the Mathematics Department of National Taiwan Normal University, from where he received his B.Sc. and M.Sc. in 1990 and 1993, respectively. In the fall of 1997, he attended the Mathematics Department of UCLA to pursue his Ph.D. degree. He only stayed one year over there and transferred to the Mathematics Department at the University of Washington in the fall of 1998, where he spent six years studying with Prof. Paul Tseng in Optimization. His research area is mainly in continuous optimization, with side interests in nonsmooth analysis and operations research.
