# nLab David Roberts

I am currently a visiting fellow at the Institute for Geometry and its Applications in the School of Mathematical Sciences at the University of Adelaide.

I work on bundle gerbes, 2-bundles, geometric stacks and internal groupoids and categories, and category theory more generally with a side interest in foundations. I have a particular interest in constructing examples in (low-dimensional) higher geometry.

I was a research associate (i.e. a postdoc) at the University of Adelaide from October 2013 to April 2015.
