**Robert Q. Berry III Ph.D.** is the Samuel Braley Gray Professor of Mathematics Education, the Associate Dean
of Diversity, Equity, and Inclusion in the School of Education and Human Development at the University of
Virginia, and the immediate Past President of the National Council of Teachers of Mathematics (NCTM). Equity
issues in mathematics education are central to Berry's research efforts within four related areas: (a)
understanding Black children's mathematics experiences; (b) measuring standards-based mathematics
teaching practices; (c) unpacking equitable mathematics teaching and learning, and (d) exploring interactions
between technology and mathematics education. Berry co-edited the 2020 book *High School Mathematics
Lessons to Explore, Understand, and Respond to Social Injustice*, which focuses on teaching mathematics for
social justice.

**Carlos A. LópezLeiva** is an Associate Professor in Bilingual and Mathematics Education in the Department of
Language, Literacy, and Sociocultural Studies at the University of New Mexico. His work focuses on the
promotion of equitable teaching and learning ecologies—in relation to social interactions, language use and
ideologies, and what counts as mathematics—that mediate the learners’ participation in and meaning making
of mathematical practices. His research comprises three areas: (1) issues of equity in social interactions, (2)
out-of-school interdisciplinary Mathematics teaching and learning, and (3) in-school Interdisciplinary
Mathematics teaching and learning.

**Kanita K. DuCloux** is interim dean in the Mathematics Department at Western Kentucky University where she has been a
faculty member since 2011. Her research focuses on mathematics teacher education, specifically improving K – 12
mathematics teaching and learning; preparing prospective and practicing teachers to teach diverse student populations
and to implement equitable instructional practices; and examining mathematics teachers' reasoning, thinking, and
beliefs about students and mathematics. She is the co-author of *Catalyzing Change in High School Mathematics:
Initiating Critical Conversations*, a publication by NCTM.

**Howie Hua** is a math instructor at Fresno State who teaches math to future elementary school
teachers. He is passionate about finding ways to humanize the math classroom, listening to how students think
about math, and building mathematical confidence in students. In 2019, Howie was named Outstanding
Lecturer for the College of Science and Math at his university. Outside of school, Howie likes to play piano, go
on walks, make math memes, and make math explainer videos.
