Character development—focused on honesty, integrity, and kindness—forms the fabric of my teaching philosophy. I embrace an open pedagogy to enable learners in becoming creators of knowledge and critical thinkers. To advance this vision, I provide a relaxed atmosphere where every student can enjoy the journey of learning through explorations of the wonders of natural phenomena or via the richness of intellectual creations.
I started teaching in 1997 in New York City. In 1999, I became a graduate student and teaching assistant at Dartmouth College. In 2001, while still in graduate school at Columbia University, I accepted my first full-time university position at The City College of the City University of New York, where I taught graduate courses in education and began training teachers.
In 2003, I accepted a tenure-track assistant professorship at the University of Puerto Rico, Mayagüez Campus. After earning tenure (2009) and becoming a full professor (2012), I took a leave of absence in 2013 to explore reviving a small independent school in Mississippi; while it lived, we renamed it MathEcoSpirit Academy.
I returned to my position in Puerto Rico in 2014, but decided to resign in 2015 to teach at the North Carolina School of Science and Mathematics (NCSSM). There, I produced two series of short videos.
In 2016-2017, I taught at three different prisons in North Carolina, through UNC’s correctional education program.
In 2017, I moved to Georgia to teach at South Gwinnett High School, a Title I school in metro Atlanta. During this time, I also began working as an educational consultant, more prominently, as the Director of Festivals for the Julia Robinson Mathematics Festival (JRMF).
In February 2019, I received the 2018 Rosenthal Prize for Innovation and Inspiration in Math Teaching awarded by the National Museum of Mathematics (MoMath).
In May 2019, I relocated with my family to Florida, while expanding my national and international work with JRMF. In my spare time, I teach at the Alachua Learning Academy and the Bhaktivedanta Academy.
In October 2019, I was appointed Courtesy Professor with the Department of Mathematics at the University of Florida.
