Taras Yavorskyi

Taras Yavors'kii studied physics at and earned PhD from National University of Lviv, Ukraine, where he was developing quantitative theory of critical phenomena in phi-4 field theories with complex symmetry order parameters. He then worked as a research associate and a post-doctoral fellow at Universities in Hanover (Germany), Waterloo (Canada), Mainz (Germany) studying quantum and classical spin models on highly geometrically frustrated lattices. He was also employed as a consultant on high-performance GPU computing in molecular dynamics at the University of Waterloo. He is an author of over 20 publications in peer-reviewed international professional journals garnering over 220 references to his work, including in journals “Science” and “Nature”. In 2013, he was appointed a Lecturerer in Mathematics at Coventry University.
