Fabian Spaeh

A picture of me

Fourth-year PhD student in computer science at Boston University advised by Alina Ene. I am broadly interested in optimization and currently working on learning-augmented algorithms for online allocation problems, submodular maximization, and opinion dynamics. Previously, I completed a bachelor’s and master’s degree in computer science at the University of Konstanz. You can contact me by email via fspaeh at bu dot edu.
