A description of my research
I do homological and homotopical algebra in the context of noncommutative geometry. Specifically I am interested in, Hopf equivariant cohomology theories, various flavors of Hochschild (co)homology, cyclic (co)homology and K-Theory. I am also interested in abstract homotopical algebra, operads, PROPs and their algebras. For the visually inclined, I have a map of my slanted view of the noncommutative geometry landscape.
Machine Learning and History
With Prof. Boğaç Ergene from University of Vermont, we have two projects. In the first project (since completed) we investigated social mobility patterns in 18th Century Ottoman Empire. For the second on-going project, using NLP tools, we are currently in the process of analyzing several Ottoman jurisprudential corpora from the 16th Century to the 20th Century. While I perform all of the computational and statistical analyses needed on the particular data sets Prof. Ergene painstakingly collected from historical sources and archives, he provides the necessary historical context and analyses of the results we obtain. We wrote six papers together with more to come in the future.
