Liversidge Lecture 2022

The Liversidge Lecture for 2022 has been awarded to Professor Timothy W Schmidt FRSN FRACI CChem of the School of Chemistry at UNSW Sydney. Professor Schmidt is internationally recognised as a molecular spectroscopist working on diverse problems from astrophysics to renewable energy. In the gas phase, he has recorded spectra of many hydrocarbon radicals for the first time and discovered new electronic excitations of the dicarbon molecule. In the condensed phase, his work concentrates on triplet-triplet annihilation and singlet fission for solar energy applications. His work has been recognised by a number of prizes including the Broida Prize (International Symposium on Free Radicals 2015), the Coblentz Award (2010), the RACI Physical Chemistry Lectureship and the RACI Physical Chemistry Medal (2021).Kaarin Anstey, from Neuroscience Research Australia of UNSW Sydney, is a world leader in cognitive ageing and dementia risk reduction. Her program of research has contributed greatly to the evidence base on dementia prevention through the identification and quantification of risk factors for dementia, the development of risk assessment tools, and the implementation of interventions. Moreover, her work has directly informed public policy and guidelines, both within Australia and globally, particularly in her collaboration with the World Health Organization. As a consequence, she has made an important, sustained, positive impact on the lives of tens of thousands of people in Australia and around the world.
