All roads seem to lead Jamie Hintlian back to Cornell
“Originally, I was thinking I might major in mechanical engineering, but then I saw how OR involved applying math, which had a lot of appeal. And I learned about modeling and simulations and game theory from Professor David Heath and it all resonated with me deeply,” Hintlian said. He declared his major and never looked back.

A life and a career spent finding the right solutions
“The kindness of Cornell has made a real difference in my life,” Kulkarni said. “They were willing to waive the application fee and then when I switched departments, Mathematics was willing to fund my second year, even though by then I was in OR. And then they made it possible for me to complete the final year of my doctoral program after I had moved to Georgia with my husband.”
