I am a research scientist in astrophysics and cosmology at the Johns Hopkins University in Baltimore, MD. My research uses scientific computing to study the cosmic web — the largest structures in the Universe — and what it can tell us about dark matter and dark energy. I am working with the SciServer to design and test the infrastructure that will house the petabyte of Indra cosmological simulations for the community to freely access and analyze.

One of the things that fascinates me about cosmology is how dark matter and dark energy are central to our current paradigm, but we have no idea what they are, or even whether they actually are anything. Strong opinions form on the many sides of the debates, and multiverses are postulated, convincing me that cosmology could greatly benefit from closer collaboration with the philosophy of science. It is my firm belief that the scientific process would be vastly improved if more scientists knew, for example, what underdetermination means.

I was formerly a research fellow at the University of Oslo in Norway, and before that, at the University of Portsmouth in England. I received my PhD from the Johns Hopkins University in 2012.
