Background

Professor István Tóth is Chair in Biological Chemistry at The University of Queensland (UQ), Brisbane, Australia, and Affiliated Professorial Research Fellow at the Institute of Molecular Biosciences, UQ. He graduated with a degree in Chemical Engineering from the Technical University, Budapest, Hungary and was awarded his PhD for his Alkaloid Chemistry research. Professor Tóth undertook a postdoctoral fellowship at Carleton University, Ottawa Canada before returning to Hungary to work as a Research Associate, then Scientific Group Leader at the Central Research Institute for Chemistry, Hungarian Academy of Science. He joined the School of Pharmacy at the University of London in 1987 as a Senior Lecturer and Royal Society sponsored Senior Research Fellow. He became a Reader in Medicinal Organic Chemistry in 1994 and was awarded a Doctor of Science degree (DSc 1994) for his work in Drug Delivery (Hungarian Academy of Sciences), before relocating to the University of Queensland in 1998 where he has built a productive research group. Professor Tóth was a visiting professor at the School of Pharmacy, University of London (1994-2004) and at the Department of Bioengineering and Therapeutic Science, University of California, San Francisco (2011-2013). Professor Tóth’s major research interests are: drug delivery, immunoadjuvants, carbohydrates, lipids, peptides, nucleosides, and nucleotides. This research has attracted over $85 million in competitive grants, research contracts and investment funds in the past 10 years. Professor Tóth has over 500 peer-reviewed publications, 45 patents, and an excellent track record in research commercialisation. He is a one of key founders of Alchemia, Implicit Bioscience Pty Ltd, Neurotide Pty Ltd and TetraQ (the commercial arm of Centre of Integrated Preclinical Drug Development). Professor Tóth is an elected RACI Fellow and Fellow of the Queensland Academy of Arts and Sciences. and Feklloiw of the Hungarian Academy of Sciences (since 2016) In 2009 he was awarded the Adrian Albert award for sustained and outstanding research in medicinal biochemistry, and a Business/Higher Education Round Table (BHERT) Award for Outstanding Achievement in International Collaborative Research and Development he obtained the Doctor Honoris Causa degree at Semmelweis university budapest Hungary (2019). Professor Tóth was appointed as a member of the ARC College of Experts (2008-2010). He was the founding (2007) then the elected (2008-2009) President of the Australian Chapter of Controlled Release Society.
