Orlando Marigliano
Algebraic statistics, applied algebraic geometry at KTH Stockholm
Research
I am interested in the connections between algebraic geometry and the fields of statistics, data science, and the natural sciences. I am a postdoctoral researcher at Math Data Lab working with Kathlén Kohn. [mdl, kk]
Main topics I'm working on: Algebraic statistical models, linear spaces of symmetric matrices, the maximum likelihood degree.
Other topics I'm interested in: random geometry and topology, singular learning theory, loss landscapes, staged trees, Bayesian networks.
I am co-organizing a collaboration project on linear spaces of symmetric matrices. [link]
