Teaching style
My teaching style is rigorous, student-centered, and rooted in clarity and connection. I believe that every student— regardless of background or confidence in math — can develop deep mathematical understanding when given the right tools, encouragement, and structure.
I blend high expectations with high support. My classroom is a place where analytical thinking is nurtured, mistakes are viewed as stepping stones, and concepts are always tied to purpose. I strive to create lessons that are visually clear, logically sequenced, and rich with real-world connections.
Awards & shining teacher moments
My students were accepted to Brown University, Harvard University, Yale University, and Cornell University. They are successfully studying there! I am so proud of them!
My own education history
I hold a Ph.D. in Mathematics and Physics. I am the author of 45 scientific articles published on Google Scholar and ResearchGate.
