Barak Shoshany is an Israeli–Canadian theoretical physicist. His work spans quantum gravity, general relativity, quantum mechanics, and scientific computing—including time and causality, implications of time travel and faster-than-light travel, and developing related computational tools.[2][3]
Early life and education
Shoshany completed his undergraduate studies in mathematics and physics at Tel Aviv University in Israel, spending his summers doing research at the Weizmann Institute of Science in Israel and CERN in Switzerland. He pursued graduate studies in theoretical physics in Canada, earning an MSc from the Perimeter Scholars International program at the Perimeter Institute for Theoretical Physics and a PhD from the Perimeter Institute and the University of Waterloo in 2019.[3][4] His PhD thesis, At the Corner of Space and Time, provided a rigorous framework connecting continuous and discrete spacetime geometries in loop quantum gravity.[5]
Career
Shoshany worked as a postdoctoral researcher at the Perimeter Institute for Theoretical Physics before joining the faculty at Brock University in 2020. He has also served as a sessional lecturer at the University of Toronto and the McMaster University School of Computational Science & Engineering. His research was supported by a Discovery Grant from the Natural Sciences and Engineering Research Council of Canada and by the Mitacs Globalink program.[2][3]
Research
Shoshany's research is in the area of time and causality in general relativity and quantum mechanics, investigating compatibility of time travel and faster-than-light travel with established physical theories. He has worked on on parallel timelines as a universal resolution of time travel paradoxes and exploring the relationship between wormholes, warp drives, and closed timelike curves.[6][7][8][9][10][11][12] New Scientist,[13] TVOntario's The Agenda,[14] BBC Future,[15][16][17] Infobae,[18] and Science & Vie[19] have published interviews with him. Shoshany published a popular science article about his research in The Conversation.[20]
Shoshany developed OGRe, an object-oriented Mathematica package for tensor computations in general relativity, and its Python port, OGRePy.[21][22][23][24] He also authored a popular C++ thread pool library for high-performance computing applications.[25][26][27]
