koldrakan

PhD student in theoretical physics at NCBJ in Warsaw, Poland. My work involved the development of cosmological models allowing for the variation of fundamental constants such as the speed of light. I also investigate phenomenological aspects of theories of quantum gravity and Lorentz Invariance violation.
