Welcome to the Polyzos Research Group at the University of Melbourne
Our research programme is focussed on the discovery of catalytic reactions and the development of enabling technologies to address two frontier challenges in modern chemistry:
Firstly achieving the direct synthesis of structurally diverse and complex molecules with the enzyme-like efficiency observed in Nature, and secondly developing efficient, sustainable methods for molecular assembly.
We pursue these challenges though the development of catalytic methods to enable the direct functionalisation of C-H bonds via transition metal and photoredox catalysis. We have a profound interest developing asymmetric synthesis methods within this context. Research in our group combines these approaches with flow chemistry methods to enable precise control over reaction parameters and scalability.
Our laboratories located at the University of Melbourne and Australia’s national research agency, CSIRO, to foster deeper collaboration and industry engagement.
Dr Anastasios (Tash) Polyzos was awarded his PhD in 2005 from La Trobe University under the direction of Professor Andrew Hughes and appointed to Research Fellow at the Australian National research agency, CSIRO in the same year. In 2008 he pursued post-doctoral research at University of Cambridge under guidance of Professor Steven V. Ley FRS. In 2011 he returned to Australia and lead the flow chemistry and catalysis group at CSIRO in Australia. He began is independent career in 2015 when he was appointed to Senior Lecture at the University of Melbourne.
His group’s accomplishments have been recognised by a number of achievements including the 2018 Max O’Conner Award and Lectureship, La Trobe University (2018) the Thieme Chemistry Journals Award (2017), Visiting Professorship, ETH Zurich (Swiss Federal Institute of Technology) (2016) and the Julius Career Award, CSIRO, Australia (2013).
His research interests include the development of new methods and enabling technologies for organic synthesis, photocatalysis, C-H reaction discovery, and the development of sustainable industrial process chemistry. He currently serves as Director of the Australian Research Council Industrial Transformation Training Centre for Chemical Industries.
