My name is Nikolaos Syrrakos and I am a PhD student currently working on calculating next-to-next-to-leading order (NNLO) corrections to scattering processes that are produced in high energy colliders, such as the LHC at CERN. The topic of my dissertation is the computation of two-loop Master Integrals with the method of differential equations. Following the LHC upgrade to High Luminosity-LHC, very precise theoretical predictions for scattering cross sections will be required to match the experimental accuracy, in order to determine any discrepancy between theory and experiment. A key ingredient of the required theoretical predictions is the computation of two-loop Master Integrals for the relevant scattering processes.

Dimitris Stavropoulos is a PhD student at the Institute of Nuclear and Particle Physics working for the KM3NeT underwater neutrino experiment as a member of the Astroparticle Physics Group. He has graduated from the School of Applied Mathematical and Physical Sciences at the National Technical University of Athens (2011-2017). He has also obtained the MSc "Physics and Technological Applications" degree (2017-2019) from NTUA-NCSR "Demokritos". His research interests focus mainly on the study of the quality of the data collected by the KM3NeT-ARCA detector. For his MSc thesis he has carried out a long-term study of the performance of the ARCA detector. For his Bachelor thesis he performed a study of the dependence of the detection of atmospheric muons on sea depth using the first data KM3NeT-ARCA detector. He has also been involved in the calibration and tests of KM3NeT detector components performed in the DOMLab of INPP. In addition, he is a member of the "Calibration Working Group" and "Operation & Analysis Working Group" in the KM3NeT collaboration.
Ms. Anna Sinopoulou is a PhD candidate of the National Technical University of Athens (N.T.U.A) and works in the Astroparticle Physics group of the Institute of Nuclear & Particle Physics, N.C.S.R. “Demokritos”. Anna holds an integrated Master of Engineering (MEng) degree in Applied Mathematical and Physical Sciences from the National Technical University of Athens (2011-2016) and a Master of Science (MSc) degree in Physics and Applications from the National Technical University of Athens (2016-2018). During her MSc studies, she has also worked as an intern in the Erlangen’s Center for Astroparticle Physics (E.C.A.P) of the University of Erlangen-Nurnberg in Germany. Anna has a teaching experience as a laboratory assistant of the Nuclear and Particle Physics laboratory of N.T.U.A where she teaches “The Monte Carlo method” and “General Physics”.
Her major research interests are in the field of Particle and Astroparticle Physics. Anna during her first-degree thesis, has completed a study on “the possibility of detecting very high-energy neutrinos with the original GRBNeT self-test array”. During her MSc, she became a full member of the KM3NeT collaboration and has completed an “optimization study of the KM3NeT detector for detecting high-activity neutrinos”. During her internship at E.C.A.P. she has studied the photomultiplier response of detector KM3NeT-ORCA detector from the data taken from its first deployed detection unit. Anna is currently working on the data from the first deployed detection units of the KM3NeT-ARCA detector, in order to find and optimize requirements for selecting well reconstructed events and to find selection criteria to identify neutrino event candidates.
Spyros K. Peroulis was born in Athens in 1993. He received his BSc Diploma in 2019 from the Physics Department of the NKUA. In 2021, Spyros completed his MSc studies in NTUA and he is currently a PhD candidate. His research interest is focused on theoretical nuclear physics. Spyros joined INPP’s theoretical nuclear physics group in 2017 in order to work on his BSc thesis, after a two-year collaboration with “NUSTRAP” group at NKUA. Now, he is working on the structural evolution of the atomic nucleus as a function of the numbers of its constituent protons and neutrons with special interest to the investigation of the electromagnetic quadrupole transitions in the nuclear landscape.
