Michal Vajzer presented his PhD thesis in June. His thesis work has contributed to the study of hard processes in nuclear collisions with the ALICE experiment. He pursued his thesis under the supervision of the ALICE groups at the Czech Technical University and the Nuclear Physics Institute ASCR under the supervision of Professor Jaro Bielcik and  Professor Jana Bielcikova.

Alberto Collu from the University of Cagliari completed his PhD thesis on the “Development and characterisation of Monolithic Active Pixels Sensors prototypes for the upgrade of the ALICE Inner Tracking System” supervised by Professor Gianluca Usai. His work has contributed to the development of innovative detectors for the upgrade of ALICE.

Sandun Jayarathna worked in the study of event structure in proton-proton collisions using correlations between charged hadrons and strange neutral particles and presented his thesis: “Transverse momentum evolution of hadron-V0 correlations in proton-proton collisions at √sNN = 7 TeV” in University of Houston. Sandun was supervised by Prof. Rene Bellwied (University of Houston). During his time as a PhD student he also carried out work on on the Quality Assurance of the ALICE data, and on the support of test beams for the ALICE upgrades.

Badrajee Piyarathna also pursued his thesis in the University of Houston working with Professor Rene Bellwied on “2-d di-hadron correlations at √sNN = 2.76 TeV using the ALICE experiment”. His thesis also contributed in the study of the event structure in the case of nucleus-nucleus collsisions while he contributed in the Quality Assurance of ALICE data as ALICE prepared for the next run of the LHC.

Xitzel Sanchez’s thesis has advanced our understanding of strange particle production in nucleus-nucleus collisions. We are glad to acknowledge her work on the analysis of the test beam results for the prototypes of the pixel detectors that will be used for the ITS upgrade. We would like to take the opportunity to thank also the ALICE group at Université de Strasbourg and CNRS-IN2P3, Strasbourg, and Professor Christian Kuhn, her supervisor, for their efforts in training the next generation of scientists.

“Identified hadron distributions in p-Pb collisions at sqrt{s_{NN}} = 5.02 TeV with the Inner Tracking System of ALICE at the LHC” was the topic of Corrales Morales’ PhD thesis. Moreover, Yasser Corrales worked on the development of the new readout boards for the ALICE Silicon Drift Detectors for RUN2.  Yasser Corrales was co-supervised by Professor Elena Botta and Dr Francesco Prino (Università degli Studi di Torino).

Riccardo Russo presented his thesis on the “Measurement of D+- meson production in p–Pb collisions with the ALICE detector” pursued under the supervision of Professor Stefania Beolé (Università degli Studi di Torino). He has also worked on improving data assurance of data from the ALICE Silicon Drift Detector.

Ilaria Aimo (Politecnico di Torino) presented her thesis on the development of innovative detectors for the ALICE Upgrade. She submitted her PhD on “Studies on monolithic active pixel sensors for the inner tracking system upgrade of the AICE experiment” last February working with Professor Michelangelo Agnello (Politecnico diTorino, Dipartimento di Scienza Applicata e Tecnologia). Furthermore, Ilaria contributed to the characterization of the Mimosa and Explorer chips for ALICE upgraded detectors.

Finally, Goran Simatovic (Department of Physics, Faculty of Science, University of Zagreb) successfully submitted his thesis on “Event shape dependent pion femtoscopy of proton-proton collisions at 7 TeV centre-of-mass energy" contributing to the development of new insights into the pion femtoscopy of pp collisions by using event shape analysis and variable sphericity.  We would like to take the opportunity to thank the ALICE group at the University of Zagreb, and Prof Mirko Planinic for their efforts in training the next generation of scientists.
