PhD Advising

I am currently supervising the PhD in Business Analytics for Krystie Dickson, with expected dissertation defense some time in 2027.

Capstone supervision

During Spring 2010, I supervised Lubka Dagorova’s honors capstone project. She created a Microsoft Excel Add-in for examining arbitrage opportunities in international stock exchanges. See more here.
