About Me

I am a theoretical physicist that lives in Zurich, Switzerland. My main research interest lies within the field of perturbative quantum field theory and its application to particle physics phenomenology that help us achieve precise predictions of observables measured at current and future colliders. In particular, I focus on higher order perturbative calculations for processes of prime phenomenological importance for new physics discoveries at the LHC.

Recent work includes QCD NLO corrections to triple vector boson production and top-antitop-Z production at LHC.

Studies and previous work

I studied physics at the Dept. of Physics in the University of Athens and then got an M.Sc. in elementary particles at the University of Durham. I then got my Ph.D. at IMAPP (University of Nijmegen, the Netherlands), under the supervision of R.Kleiss, for work that varied from numerical methods used in phase-space integration of differential cross sections [Monte Carlo and Quasi Monte Carlo], to recent developments in analytic results for tree level Yang-Mills amplitudes [MHV and BCFW]. Thereafter I started post-doctoral research at the university of Hawaii at Manoa where I got involved into NLO QCD calculations.

Monte-Carlo and Quasi Monte-Carlo

Here are some explanatory notes and plots relevant to my work on Monte-Carlo and Quasi Monte-Carlo integration. There is also some C++ code to generate Quasi Monte-Carlo sequences and estimate the integration error when using Quasi Monte-Carlo. This code was designed for demonstration purposes and probably suffers from portability issues. If you would like to use it but have problems with it please let me know.

Automatic Integral Reduction

This is the web page of AIR, a package of maple programs for the reduction of loop tensor integrals to master integrals via a variant of the Gauss elimination method called the ‘Laporta algorithm`.
