Professor Istvan Toth


Professor Istvan Toth (The University of Queensland) is a chemical engineer with a significant international reputation as a medicinal chemist. Professor Toth's research has focused on the development of versatile delivery mechanisms that can be adapted to suit a broad range of drug and vaccine candidates. His expertise lies in drug delivery, immunoadjuvants, vaccine delivery, peptides, carbohydrates, lipids, nucleosides, and nucleotides. Professor Toth has a strong track record in research commercialisation as a key founder of Alchemia (listed on the Australian Stock Exchange), Implicit Biosciences Pty. Ltd., and Neurotide Pty. Ltd. He is also a key partner in the Queensland Preclinical Drug Development Facility (TetraQ), established in 2005 as a world-class facility to provide integrated preclinical drug development services to Queensland and Australian biotechnology companies engaged in human therapeutics development.
