Project:

My research is on non-equilibrium quantum field theories (QFT) based on the Kadanoff-Baym equation. My current project is to apply the method of QFT to phenomena in biological systems, especially memory formation of the human brain. I numerically trace non-equilibrium processes with quantum electrodynamics to describe the phenomena. My project can be also applied to the formation of quark-gluon plasma in heavy ion collisions, Bose-Einstein condensation in low temperature physics.
