International Experience:

Currently I have active collaboration with many worldwide universities: USA, United Kingdom, China, Canada, Pakistan, Saudi Arabia, Egypt, Singapore, Australia, Czech Republic, Poland, India and Denmark. I also worked as a full time Visiting Researcher with CS Department, University of Waterloo, Canada  (QS University World Ranking: 149 and QS Subject Wise Ranking 23) and Brandon University, Canada. I worked as a researcher with Military University of Technology, Poland, and my PhD from Poland's top research institute Polish Academy of Sciences, Poland  (Research Institute World Ranking 76 and Poland Ranking is 1). Currently, I am working in Post Quantum Research Group inDTU Compute, Technical University of Denmark, Denmark  (QS World Ranking 99 and Denmark Ranking 2). I have been selected by Heidelberg Laureate Forum, Germany (2019) to participate among top 100 young researchers all over the world in Computer Science.
