​Quantum Field Theory (nonperturbative aspects)

Neutrino Physics

Black Holes

Cosmology

​

I obtained a PhD from UC Berkeley in physics, under the masters supervision of Saul Perlmutter (2011 Nobel prize for discovering the cosmological constant) and PhD supervision of Marty Halpern studying string theory and conformal field theories.  

I was a double major at Caltech, obtaining BS degrees in physics and in math, where I worked with John Preskill on quantum computers.

   

I taught string theory for 6 years at the University of Pisa and Scuola Normale di Pisa.  Now I sometimes organize on-line lecture series, for example on Coleman's QFT class.  Contact me if you want to join.

   

I have 120 papers in peer-reviewed international journals.

Recently I have mostly been interested in trying to understand the proposal that the QCD vacuum contains magnetic monopoles or center vortices, which are responsible to confinement.  To do this, our group has developed a new formalism for treating nonperturbative objects (solitons) in quantum field theory.

I am also interested in neutrinos (decoherence and experiments), dark matter (models where each dark matter particle is galaxy-sized), black holes, oscillons, baryon accoustic oscillations, etc.
