Bio

I work on classical and quantum field phenomena in Particle Physics and Cosmology. My primary focus is Baryogenesis in the Early Universe, Inflation and Preheating, Topological Defects and the development of out-of-equilibrium field theory methods. Much of my research involves High-Performance Computing, in addition to analytical calculations and model-building. 

Current research projects include: 

Real-time quantum field theory methods (Lefshez thimbles, the Classical-Statistical formalism, 2PI). In collaboration with Paul Saffin, Zonggang Mou, Peter Millington, University of Nottingham.

Quantum field effects in the very early Universe (Corrections to inflaton dynamics, curvaton models). In collaboration with Magdalena Eriksson, Jen Oluf Andersen, NTNU.

First order phase transition dynamics in the Early Universe (Bubble nucleation, bubble dynamics, baryogenesis, gravitational waves). In collaboration with Gerhard Ungersbäck.
