Hello!
I am a Professor in the Mathematics Department at the CUNY NYC College of Technology.  I am Director of the Mathematics Education program, teach mathematics education classes,  and have the privilege of working with future NYC mathematics teachers.
I am also a Faculty Research Associate for the CUNY Computer Science Integration in Teacher Education (CITE) Research Practice Partnership, and lead the City Tech Math Education Team, which is part of the CUNY Computer Science Integration in Teacher Education (CITE) — a four-year initiative to support CUNY faculty to integrate state standards and align computing content and pedagogy with CUNY teacher education programs. I enjoy working with students and have mentored  more than 45 student teachers and 25 undergraduate student research projects. 

I am the PI on the “My Brother’s Keeper Teacher Opportunity Corps II grant” of $1.3 M from NYSED (2023-2028), which provides tuition support and professional development to teacher candidates for the next five years. The grant will help create and support a pipeline of a diverse and talented teaching force for New York City Schools. I am also the Co-PI on an NSF S-STEM grant “Engaging, Empowering, and Retaining New Scholars in Science, Technology, Engineering and Mathematics,” $999,625 (2019-2024), which supports, and helps retain and graduate academically talentedSTEM students.

I was the founding director of the New York City Men Teach (NYCMT)  at City Tech, and directed the program from 2016 to 2019. I have also been advising the International Baccalaureate (IB) program, in relation to its mathematics (standard level and high level) curriculum development, assessment,  and examiner training since 2007. From 2007 to 2012 I was the chief examiner for Mathematical Studies of the International Baccalaureate (IB) Diploma Program, and led the international examination team responsible for writing exams and overseeing examinations, and sat on the Examining Board.

My research interests are in philosophy of mathematics education, dialogic teaching, teacher professional identity and teacher professional learning. I am currently working on a book, which in 2021 was awarded the CUNY Book Completion Award— a competitive CUNY-sponsored grant for faculty in the arts, humanities and social sciences.
