I am Dennis Ulmer, a postdoctoral researcher in natural language processing and machine learning at the Institute for Logic, Language and Computation (ILLC) at the University of Amsterdam (UvA), where I am working with Prof. Ivan Titov.

My current research interests include uncertainty quantification and communication methods with application to NLP, better experimental design, generalization, and many more!
