Diego Blas obtained his PhD in Physics in the University of Barcelona (Spain) in 2008. He was a postdoctoral researcher in the group of Prof. Shaposhnikov at the École Polytechnique Fédérale de Lausanne till 2011. After a short research period in New York University, he moved to the Theory Division of CERN as a fellow in early 2012. He became a Staff Member of the Theory Division at CERN in 2014. He joined King’s College London in February 2018 as a Senior Lecturer in the Department of Physics. . 

Research interests

Broadly: theoretical physics, gravitation and cosmology. 

My current research is in the interface of theoretical physics and astrophysics. This is interaction flows both ways: I try to use concepts from theoretical physics to better understand astrophysical phenomena (in particular in the area of large scale structure) and I am also interested in using astrophysical phenomena to constrain fundamental physics. My main directions in the last years have been: 

  • Analytical techniques to study the distribution of matter at large scales (large scale structure).
  • Development of theories of gravity without Lorentz invariance (theoretical and phenomenological aspects). These are relatively unexplored candidates for quantum gravity. 
  • Use of pulsar timing to constrain aspects of dark matter. In particular, pulsar phenomenology is affected by very low mass candidates and provides the strongest bounds for some models. 
  • Participation in the theoretical aspects of the Boltzmann code CLASS. The code is used to analyse multiple aspects of cosmology.
