Office Hours
I graduated with a B.S. in Mathematics in 1999 from Sharif University of Technology, Tehran, Iran, and with a Ph.D. in Mathematics from Stony Brook University in 2005. I joined Siena College in 2011 after visiting positions at the University of Oregon (Eugene, OR) and Trinity College (Hartford, CT).

My Siena Experience
My Teaching Philosophy
The core of my teaching philosophy is problem solving. I encourage my students to improve their mathematical skills and understanding through group projects and presentations. I am also a believer in Inquiry Based Learning methodology after attending two workshops and implementing the IBL techniques in several of my classes.
What I Love About Siena
I love my students and appreciate their hard work in my classes. I value the fact that my students take my classes seriously and do their best. Siena College is a vibrant institution with many bright students and faculty.
My Favorite Courses to Teach
My favorite course to teach at Siena is Euclidean and Non Euclidean Geometry. I run this course as an inqury based learning course, where student presentations are the major part of our meetings.
