About Me

Sebastian Zajac earned his PhD in Physics at the University of Silesia in Katowice. He is currently a theoretical physicist, an assistant professor and an associate dean for infrastructure at the Faculty of Mathematics and Natural Studies, Cardinal Stefan Wyszynski University in Warsaw (Poland).
He is a American Physical Society member. The focus of his research is mathematical physics, statistics and data analysis, in particular phenomenology of neutrino physics and geometry, topology and Category Theory in Quantum Mechanics and Quantum Field Theory. His latest publications center around the flavour problem in the field of neutrino physics. With prof. Piotr Sulkowski they are trying to characterize RNA and protein structures by their topological characteristics called genus.

  • Neutrino 2018
    XXVIII International Conference on Neutrino Physics and Astrophysics
    June, 4-9, Heidelberg, Germany

    The biennial conference focuses on the current status of neutrino physics, its interplay with astronomy and cosmology and the future prospects of these fields. It is organised by the Max-Planck-Institut für Kernphysik and the Karlsruhe Institute of Technology. The programme consists of invited plenary talks and contributed poster presentations. Several satellite events take place in the days before and after the conference.

  • String-Pheno 2018
    Faculty of Physics, University of Warsaw, July 2-6, 2018.

    Phenomenological aspects of string theory have moved to the forefront of research efforts in the theoretical high energy physics community. This conference aims at bringing together top researchers in the field to present and discuss recent breakthroughs bridging fundamental theory and its implications for particle physics and cosmology. A special emphasis will be placed on innovative mathematical techniques and an effort will be made to include a number of leading mathematicians and mathematical physicists. We are particularly keen to encourage young researchers and will attempt to feature their work prominently at this conference.

  • 2018 Summer Conference on Topology and its Applications
    Hosted by Western Kentucky University,
    July 17-20, 2018, Bowling Green, KY

    Western Kentucky University will host the 33rd Summer Conference in Topology and its Applications from the morning of Tuesday, July 17, 2018 to Friday, July 20th, 2018. Western Kentucky University is in Bowling Green, Kentucky. The main meeting venue will be Snell Hall, at the northeast end of campus. In addition to the traditional areas usually represented, the conference will include two sessions on applications of topology in the physical sciences. The significance of the interplay between topology and physical sciences was highlighted in the awarding of the 2016 Nobel Prize in Physics to three researchers using topological methods. We are pleased to announce that 2016 Nobel Laureate J. Michael Kosterlitz will deliver a keynote address.

  • XII Latin American Symposium on High Energy Physics
    November, 26-30, 2018, San Mgiuel, Peru

    The Latin American Symposium of High Energy Physics (SILAFAE) congregates the Latin American particle physics community, with the aim of discussing our current knowledge and the future perspectives in particle and astroparticle physics, including topics such as gravitation and cosmology. This is achieved mainly through theoretical and experimental plenary talks, as well as parallel oral contributions and poster presentations.
