Simon Sirca was born on February 27, 1969, in Ljubljana, Slovenia. He studied physics at the Faculty of Mathematics and Physics, University of Ljubljana, and acquired his first research experience as a young researcher at the Jozef Stefan Institute in Ljubljana and the Institute for Nuclear Physics at the University of Mainz, Germany, concluding his PhD work with the thesis Axial form-factor of the nucleon from coincidence pion electroproduction at low Q2. He was a postdoctoral research associate at the Massachusetts Institute of Technology and the Thomas Je_erson National Accelerator Facility (Jefferson Lab) in the USA. His main research is in the field of hadronic structure and dynamics as explored by scattering of electrons on light nuclei, exploiting state-of-the-art polarized beams, polarized targets, and techniques of recoil polarimetry. He is also involved in theoretical work on quark models of hadrons, with the focus on electroweak processes like pion electroproduction in the nucleon resonance region. He is the head of the research group Structure of Hadronic Systems that has been active in the OOPS and BLAST Collaborations at MIT, Hall A Collaboration at Je_erson Lab, and the A1 Collaboration at Mainz. He is an Associate Professor at the Faculty of Mathematics and Physics, University of Ljubljana, where he has been teaching numerous courses in Mathematical Physics, Modern Physics I and II, and Mathematical Physics Practicum (Computational Physics). Martin Horvat was born on April 25, 1977, in Maribor, Slovenia. He completed his physics studies at the Faculty of Mathematics and Physics, University of Ljubljana, Slovenia, with the PhD thesis Uni-directional transport in billiard chains, and continued as a postdoctoral research associate at the Department of Mathematics, University of Bologna, Italy. His research work is devoted to classical and quantum non-linear dynamics, to transport properties in extended systems, to the quantum-classical correspondence, to theoretical and applied aspects of quantum mechanics on the classical phase space, as well as to statistical mechanics and its origin in dynamics. As a teaching assistant at the Faculty of Mathematics and Physics he has led the Physical Laboratory Course II and has taught the courses in Basic Applied Mathematics, Physics I, and Physics II.
