### About Me

I am a second year Ph.D. student in the Education in Mathematics, Science, and Technology program at UC-Berkeley. Prior to attending Cal, I taught for nine years at a public high school in suburban Milwaukee. I thoroughly enjoyed working with a driven student body, and a knowledgeable staff. A particular focus of my efforts was spent in developing investigatory-type activities that aimed at actively engaging students in the process of building comprehensive understanding of mathematical concepts. Also, during my final year in the classroom, I was able to use and get a glimpse at the power of using an interactive whiteboard to enrich students’ understanding of geometry. While teaching, I obtained a M.S. degree in Curriculum and Instruction (specialization: mathematics education) at the University of Wisconsin-Madison. Broadly speaking, I am interested in determining what teacher actions lead students toward deep, nuanced forms of understanding. Also, to further specify what are the attributes of this form of knowing. Additionally, I am interested in studying how a teacher’s pedagogical content knowledge develops.
