Here is my Ph.D. thesis.

During my Masters degree, I studied a graph invariant based on the transition matrix of a discrete time quantum walk. Here is my thesis.

I am interested in the second subconstituents of strongly regular graphs. This led me to look at triply regular graphs. Here are some notes on triply regular graphs.
