I am a senior postdoctoral scholar at the California Institute of Technology. I study a variety of topics in theoretical and observational cosmology with a focus on using cosmological data to learn about fundamental physics. My main current interests are Inflation, which pertains to the physics of the very early Universe, and galaxy clustering surveys.
Follow the links below to read more about the topics I work on or have a look at my publications on the arXiv. The research pages are still under construction.
|  Neutrino Cosmology|
|  Galaxy Surveys|
|  Dark Energy|
|  Weak Gravitational Lensing|
I received my PhD in physics at UC Berkeley, where I studied dark energy and other topics in theoretical cosmology under the supervision of Eric Linder and Saul Perlmutter. Before this, I obtained my "Doctoraal" (equivalent to the MSc degree in the US system) from the University of Leiden in the Netherlands. For my thesis in Leiden, I worked on cosmic string interactions with Ana Achúcarro.
After leaving Berkeley, I first worked as a postdoctoral scholar in Spain at the Institut de Ciències del Cosmos at the University of Barcelona (ICCUB) and in the SOM ("Sabor y Origen de la Materia") group at the Instituto de Física Corpuscular (IFIC) in Valencia. During this period, I mainly worked with Licia Verde, Olga Mena and others on topics in large scale structure and neutrino cosmology, and was active in the BOSS (Baryon Oscillation Spectroscopic Survey) collaboration. After this, I moved to Pasadena, CA, to be a Caltech postdoctoral researcher at NASA's Jet Propulsion Lab and now a Caltech senior postdoc.
