Dr Hessam Mehr

  • Research Fellow (School of Chemistry)

Biography

Hessam Mehr is a Leverhulme Early Career Research Fellow working at the interface of chemistry, robotics, and computing science.

Following completion of his undergraduate degree in Electrical Engineering (Sharif University of Technology, Tehran), he moved to Canada for a PhD in supramolecular chemistry with Prof. Mark MacLachlan (University of British Columbia, Vancouver), which he finished in 2017. He briefly left the academia to work on automated analysis of drug samples using NMR at Health Canada before coming to Glasgow to join the Cronin group as a post-doc in March 2018. He was involved in the development and validation of the XDL chemical programming language and exploration of its applications as universal code for chemical synthesis and autonomous discovery. Between February 2021 and April 2022, he oversaw the evolution of XDL from version 1.0 to 2.0, adding higher-level language constructs for expressing more complex chemical programs as well as an intuitive abstraction for executing multiple programs in parallel.

In May 2021, Dr Mehr was awarded a Leverhulme Early Career Fellowship (starting May 2022) in support of his proposal for next generation chemical discovery engines.

Research interests

  • Autonomated chemical discovery in complex systems
  • Probabilistic and logic techniques applied to discovery
