Virginia Tech's Computational Modeling and Data Analytics (CMDA) major

In Spring 2015, Virginia Tech launched this new undergraduate major, a collaboration between the departments of Computer Science, Mathematics, and Statistics. Faculty have developed ten new courses for the major. Other departments have designed specialized options for students seeking to exercise CMDA skills in particular applications (biology, economics, physics). The first class graduated in May 2017. As of January 2019, CMDA has produced over 100 alumni and has 475 current students pursuing the major.
