Welcome

I am a theoretical physicist working at the Deutsches Elektronen-Synchrotron since April 2017. Before coming here, I held postdoctoral positions at SLAC, LAPTh Annecy (also visiting scientist at CERN), and the University of Florida. I originally got my PhD from Brown University in 2011.

More on my academic path can be found on my CV.

Research

My research focuses on Quantum Field Theory, String Theory, the relation between the two, and their fruitful interplay with contemporary mathematics. Performing explicit computations of important physical quantities at weak and strong coupling, and exploring their results to establish and exploit connections with new mathematical structures, lies at the core of my approach.

In particular, I have achieved significant contributions in the study of quantities such as anomalous dimensions, string state energies, Wilson loops, and more recently scattering amplitudes, which form a bridge between theory and experiment. To this end, I have employed and continue to further develop a wealth of complementary methods, ranging from gauge/string duality and integrability, to lattice discretization, and the exploitation of the expected analytic behavior of the relevant physical quantity.

Ultimately, my research aims towards an all-loop solution of an interacting, four-dimensional gauge theory, for the simplest example of planar, maximally supersymmetric Yang-Mills theory. It is very likely that along the way, the new insights gained and computational tools built, will also find applications to the real world of elementary particles, and their interactions.

Teaching

I greatly enjoy transferring knowledge, and during my PhD I had the chance to be a teaching assistant for many undergraduate courses ranging from Modern Physics to Classical Mechanics or Electromagnetism. The experience that shaped my teaching philosophy was my collaboration with Professor Leon Cooper on the design and teaching of an interdisciplinary course exploring the relation of physics and art.

My interest in teaching has also led me to attend the Teaching Certificate I & III programmes at Brown University's Sheridan Center for Teaching & Learning. After my PhD, I had the opportunity to give a specialized course on Amplitudes & Symbols, and also give guest lectures in graduate Quantum Mechanics I, Quantum Field Theory, II and Introduction to Supersymmetry and Supergravity.
