Honorary Group Leader, Maleszka Group - From molecules to behaviour

Ryszard Maleszka received his MSc and a PhD from the Department of Genetics, University of Warsaw and has done postdoctoral work at the National Research Council of Canada before moving to Australia in 1987. Since 1998 he has been spearheading a research theme called ‘From Molecules to Memory’ that uses invertebrate model systems to study the genotype to phenotype link, and to understand how epigenetic modifications contribute to environmentally-driven phenotypic plasticity and the maintenance of memory. He is a member of several genomic consortia and advisor to genomic databases. He has published over 100 papers including research and popular articles, reviews and book chapters.

Research interests

  • Integration of genomic and environmental stimuli via epigenomic modifications
  • Epigenetic mechanisms controlling behavioural development and memory storage in the brain
  • How contrasting phenotypic and behavioural outputs are produced from the same genome.

Recent grants
