I am a medicinal chemist and postdoctoral research fellow at the University of Queensland, Australia, where I obtained my BSc (Hons) with a major in organic chemistry in 2011. Following this, I worked at the Institute for Future Environments and later the Centre for Tropical Crops and Biocommodities at QUT, where I gained experience in analytical chemistry, as well as molecular biology and genetics. In 2015, I returned to UQ to begin my PhD in the design and synthesis of novel antifungals targeting invasive infection under the supervision of Prof. Craig Williams and Prof. Luke Guddat, which I completed in 2019. My combined experience in synthetic chemistry - particularly in the synthesis of heterocyclic small molecules - and molecular biology has since led to my current position at UQ under the supervision of Prof. Avril Robertson, where my focus is once again on the design and synthesis of novel antifungals. Broadly, my research interests lie in the pursuit of drug design and development campaigns addressing difficult or under-researched clinical concerns, and in particular, the use of novel bioisosteric approaches to improve drugability and drug efficacy.

More recently, I have developed an interest in Australian mushroom species. Very little recorded knowledge on our endemic mushrooms species exists. My research in this space seeks to characterise the genetic and molecular features of Australian wood rot mushrooms, which are critical players in maintaining and restoring the health of our unique forests ecosystems. With this information we aim to better understand our fungal biodiversity and the ecological roles they play, and to explore their potential uses in several industries. We are also investigating the biological activity of extracts and molecules derived from these mushrooms against models of human diseases, such as Alzheimer's, cancer, and drug-resistant microbial infections.

Prof David Ascher is currently an NHMRC Investigator and Director of the Biotechnology Program at the University of Queensland. He is also Head of Computational Biology and Clinical Informatics at the Baker Institute.

David’s research focus is in modelling biological data to gain insight into fundamental biological processes. One of his primary research interests has been developing tools to unravel the link between genotype and phenotype, using computational and experimental approaches to understand the effects of mutations on protein structure and function. His group has developed a platform of over 40 widely used programs for assessing the molecular consequences of coding variants (>7 million hits/year).

Working with clinical collaborators in Australia, Brazil and UK, these methods have been translated into the clinic to guide the diagnosis, management and treatment of a number of hereditary diseases, rare cancers and drug resistant infections.

David has a B.Biotech from the University of Adelaide, majoring in Biochemistry, Biotechnology and Pharmacology and Toxicology; and a B.Sci(Hon) from the University of Queensland, majoring in Biochemistry, where he worked with Luke Guddat and Ron Duggleby on the structural and functional characterization of enzymes in the branched-chain amino acid biosynthetic pathway. David then went to St Vincent’s Institute of Medical Research to undertake a PhD at the University of Melbourne in Biochemistry. There he worked under the supervision of Michael Parker using computational, biochemical and structural tools to develop small molecules drugs to improve memory.

In 2013 David went to the University of Cambridge to work with Sir Tom Blundell on using fragment based drug development techniques to target protein-protein interactions; and subsequently on the structural characterisation of proteins involved in non-homologous DNA repair. He returned to Cambridge in 2014 to establish a research platform to characterise the molecular effects of mutations on protein structure and function- using this information to gain insight into the link between genetic changes and phenotypes. He was subsequently recruited as a lab head in the Department of Biochemistry and Molecular Biology at the University of Melbourne in 2016, before joining the Baker Institute in 2019 and the University of Queensland in 2021.

I am a Senior Research Fellow, NHMRC Emerging Leader Fellow, and Group Leader at UQ Frazer Institute. I was awarded my PhD in late 2017 by Biomedicine Discovery Institute, Monash University. Under the UQ Health Research Accelerator (HERA) program, I lead a team to investigate T and B cell responses that profoundly regulate vaccine responses, viral clearance, and anti-tumour immunity.

My research program employs combinatorial methodologies of Biochemistry and Immunology to uncover new molecular mechanisms controlling T-cell-mediated immunity:

1. The action of T cells is required in antibody responses for suppressing viral infection or tumour growth and to confer protection upon vaccination. In particular, follicular helper T (Tfh) cells, a specialised subset of CD4+ T cells, essentially instruct the B cells to produce long-lived antibody protection. The knowledge of Tfh cells has fundamentally enabled vaccine development and therapy design for autoimmune diseases.

2. T-cell-derived cytokines play pivotal roles in both humoral and cellular immunity. Particularly, interleukin-21 (IL-21) is essential for supporting germinal centre (GC) reaction, where the B cell memory and long-lived antibody responses are generated. Besides, IL-21 is also the only known cytokine to maintain the functionalities of CD8+ T cells in the context of chronic infections or cancers by preventing a loss-of-function program termed 'exhaustion'.

This research program has generated multiple cutting-edge discoveries in the field, producing publications as 1st or joint 1st authors in top-tier journals including Nature Immunology, Science Immunology, and Nature Communications.

The molecular evolution of cytochrome P450 Enzymes: biological catalysts of unprecedented versatility.

Cytochrome P450 enzymes (CYPs, P450s) especially those responsible for drug metabolism in humans, are the unifying theme of the research in our lab. These fascinating enzymes are catalysts of exceptional versatility, and functional diversity. In humans they are principally responsible for the clearance of a practically unlimited variety of chemicals from the body, but are also critical in many important physiological processes. In other organisms (plants, animals, bacteria, fungi, almost everything!) they carry out an unprecedented range of functions, such as defense, chemical communication, neural development and even pigmentation. P450s are involved in the biosynthesis of an unequalled range of potent, biologically active natural products in microbes, plants and animals, including many antibiotics, plant and animal hormones, signalling molecules, toxins, flavours and fragrances. We are studying how P450s have evolved to deal with novel substrates by reconstructing ancestral precursors and evolutionary pathways, to answer such questions as how did the koala evolve to live on eucalyptus leaves, a toxic diet for most mammals.

The capabilities of P450s are only just coming to be fully recognized and structural studies on P450s should yield critical insights into how enzyme structure determines function. For example, recently we discovered that P450s are present within cells in the Fe(II) form, a finding that has led to a radical revision of the dogma concerning the P450 catalytic cycle, and has implications for the control of uncoupling of P450 activity in cells. Importantly, the biotechnological potential of P450s remains yet to be exploited. All of the specific research themes detailed below take advantage of our recognized expertise in the expression of recombinant human cytochrome P450 enzymes in bacteria. Our group is interested in finding out how P450s work and how they can be made to work better.

Artificial evolution of P450s for drug development and bioremediation: a way of exploring the sequence space and catalytic potential of P450s. The demonstrated catalytic diversity of P450 enzymes makes them the ideal starting material for engineering sophisticated chemical reagents to catalyse difficult chemical transformations. We are using artificial (or directed) evolution to engineer enzymes that are more efficient, robust and specialized than naturally occurring enzymes with the aim of selecting for properties that are commercially useful in the areas of drug discovery and development and bioremediation of pollutants in the environment. The approach we are using also allows us to explore the essential sequence and structural features that underpin all ~12000 known P450s so as to determine how they work.

Synthetic biology of enzymes for clean, green, solar-powered chemistry in drug development, bioremediation and biosensors. We have identified ancestral enzymes that are extremely thermostable compared to their modern counterparts, making them potentially very useful in industry, since they can withstand long incubations at elevated temperatures. They can be used as ‘off the shelf’ reagents to catalyse useful chemistry, such as in in drug discovery and development, fine chemicals synthesis, and cleaning up the environment. Working with drug companies, we are exploring how they can be best deployed in chemical processes and what structural features make them efficient, robust and specialized. We are also immobilizing P450s in virus-like-particles as ‘designer’ reagents that can be recovered from reactions and reused. To make such processes cheaper and more sustainable, we are using photosynthesis to power P450 reactions for clean, green biocatalysis in microalgae.
