Andreas Papaefstathiou

Assistant Professor of Physics

Andreas PapaefstathiouI study Nature at the most fundamental level, with the aim of understanding the basic building blocks of matter and energy and their interactions. This involves the study of the tiniest particles that we know of - quarks, leptons, gauge bosons and the Higgs boson.

Collider Experiments

The best way to investigate Nature at the sub-microscopic level is through experiments that rapidly smash particles together at very high energies and record the outcomes. The biggest such experiment is the CERN Large Hadron Collider in Geneva, Switzerland, colliding protons together at  99.9999991 percent the speed of light. There are plans for an even bigger machine, currently known as the "Future Circular Collider", which will be 7-8 times more powerful than the Large Hadron Collider.

I specialize in the phenomenology of particle physics. I write simulation tools and perform calculations that are crucial for the success of modern particle physics experiments. In particular, they allow us not only to predict what will be seen at experiments, but also to design future experiments and interpret their results.
