  • Expertise


    In 2015, Shahriar Shahriari was recognized for his commitment to bringing more students from underrepresented groups into the field of mathematics with what is widely considered the nation’s top prize for teaching mathematics—the Mathematical Association of America’s Deborah and Franklin Tepper Haimo Award for Distinguished Teaching in Mathematics.

    Known for classes that encourage student-driven discovery, he published the materials for his honors Calculus class as a textbook, titled Approximately Calculus, which won the American Library Association’s Choice Award for Outstanding Academic Title in 2007.

    Shahriari’s research focuses principally on chain partitions and cut-sets of Boolean Lattices and other partially ordered sets.
