Cognitive neuroscience of spatial asymmetry: behaviour, genes and brain imaging. When humans distribute their attention in space, biases or asymmetries of spatial attention exist. Healthy individuals exhibit a processing advantage favouring left space but this advantage is lost in disorders such as unilateral spatial neglect, ADHD and dyslexia. This project will develop novel electrophysiological methods to dissociate the sensory, attentional, decision-making and motoric contributions to spatial ....Cognitive neuroscience of spatial asymmetry: behaviour, genes and brain imaging. When humans distribute their attention in space, biases or asymmetries of spatial attention exist. Healthy individuals exhibit a processing advantage favouring left space but this advantage is lost in disorders such as unilateral spatial neglect, ADHD and dyslexia. This project will develop novel electrophysiological methods to dissociate the sensory, attentional, decision-making and motoric contributions to spatial asymmetries. By interfacing electrophysiology with genetic, neurochemical and brain imaging methods, this project will comprehensively map the biology of spatial asymmetry. This knowledge is vital to developing effective treatments for disorders where atypical patterns of spatial asymmetry index neurological vulnerability.Read moreRead less
Bias and allostery at the calcium sensing receptor. This project aims to provide a mechanistic and dynamic picture of the structure, function and physiology of the human calcium sensing receptor (CaSR), which is critical for vertebrate life. By responding to chemicals in the body, it acts as a universal nutrient sensor to maintain extracellular calcium homeostasis and mediate biological functions, including neurotransmission, inflammation, digestion, blood pressure and development. However, it i ....Bias and allostery at the calcium sensing receptor. This project aims to provide a mechanistic and dynamic picture of the structure, function and physiology of the human calcium sensing receptor (CaSR), which is critical for vertebrate life. By responding to chemicals in the body, it acts as a universal nutrient sensor to maintain extracellular calcium homeostasis and mediate biological functions, including neurotransmission, inflammation, digestion, blood pressure and development. However, it is not known how this single receptor controls the actions of multiple ligands to mediate numerous functions. By elucidating the roles of the CaSR and its ligands, this project aims to better understand fundamental physiological processes.Read moreRead less
Linkages between productivity and consistent behavioural traits in fish: implications for harvesting, climate impacts, and selective breeding for aquaculture. The extent to which behavior, growth and reproduction are genetically linked in fish populations is unknown, but critical for predicting the impacts of fish harvesting and climate warming, and developing fish stains for aquaculture. If strongly linked, fish harvest will always remove aggressive, large and productive fish, requiring their p ....Linkages between productivity and consistent behavioural traits in fish: implications for harvesting, climate impacts, and selective breeding for aquaculture. The extent to which behavior, growth and reproduction are genetically linked in fish populations is unknown, but critical for predicting the impacts of fish harvesting and climate warming, and developing fish stains for aquaculture. If strongly linked, fish harvest will always remove aggressive, large and productive fish, requiring their protection; in aquaculture, selecting for productive fish will also increase aggression-related injuries. If not strongly linked, we may be able to select for high productivity and low aggression in fish, or high productivity and low metabolism, thus reducing feed costs in aquaculture associated with aggressive behaviour leading to injury and infection, and reduced growth at warmer temperatures.Read moreRead less
Parameter estimation for genetic time-series data: Theory and methods. This project aims to develop a novel computational framework for solving parameter estimation problems in evolutionary modelling by leveraging genetic time-series data measured by Next-Generation Sequencing technologies. It will foster international collaboration, cutting across disciplines.

This project aims to develop a novel computational framework for solving parameter estimation problems in evolutionary modelling by leveraging genetic time-series data measured by Next-Generation Sequencing technologies. It will foster international collaboration, cutting across disciplines. By introducing new techniques from signal processing and tools from random matrix theory commonly employed for mobile wireless communications, it seeks to design scalable inference methods for resolving mutational fitness effects from genetic time-series measurements of complex evolving populations. This would enable new understanding of complex adaptive systems, such as pathogen evolution, host-immune dynamics, and acquisition of drug resistance. Read moreRead less
Investigating the role of the innate immune complement system in the abnormal development of the central nervous system. Past research has discovered a surprising link between the immune system, dietary folate deficiency and the development of the embryonic brain. This project will investigate the immune system in the developing brain, in order to understand the causes of developmental defects such as neural tube defects, and the role dietary folate plays in this process.
Cannabis and the brain: the good, the bad and the unknown. Cannabis is the most widely used illicit drug but much remains unknown about how it affects the brain. This research will examine effects on brain cells through to whole brain function in humans to determine how cannabis use may lead to impaired thinking or psychological symptoms and why cannabis might affect individuals in different ways.
Expanding the molecular tool set for structural studies of proteins and their complexes. Many applications in medical science and drug development depend on our ability to determine the 3D structures of proteins, protein assemblies and protein-ligand complexes. This project will develop novel lanthanide-binding tags and crosslinking agents that can be coupled to unnatural amino acids introduced into proteins with advanced protein chemistry techniques. These new tools will facilitate the collecti ....Expanding the molecular tool set for structural studies of proteins and their complexes. Many applications in medical science and drug development depend on our ability to determine the 3D structures of proteins, protein assemblies and protein-ligand complexes. This project will develop novel lanthanide-binding tags and crosslinking agents that can be coupled to unnatural amino acids introduced into proteins with advanced protein chemistry techniques. These new tools will facilitate the collection of structure restraints by nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR) and mass spectrometry, which are needed to generate accurate models of proteins and their complexes with other molecules. Major beneficial outcome will include an increase in the number of protein targets amenable to rational drug design and improved methods for generating new drug leads.Read moreRead less
