Chris is a lecturer in environmental microbiology at the School of Biological Sciences at Monash University.

Chris is dedicated to understanding how bacteria can exist in extreme environments. He’s particularly interested in understanding the metabolic basis of biodiversity of soil microorganisms and persistence of pathogenic bacteria. To do so, he adopts a transdisciplinary approach to study biological processes at all levels of organisation: from enzymes to ecosystems.

Within the Centre, Chris is interested in understanding metabolic scaling relationships within and between microorganisms. He is additionally exploring the evolutionary and ecological significance of morphological changes during bacterial persistence.

Dr Michael McDonald
Monash University

Mike is a lecturer and group leader in the School of Biological Sciences at Monash University.

Mike is interested in the genetics of adaptation. His experimental approach is to grow populations of yeast (and other microbes) for 1000’s of generations in a variety of environments, observing evolution as it happens. With the tools of whole genome sequencing, statistical analysis and genetic engineering his group works towards finding rules for how new mutations and natural selection shape a better adapted organism.

Dr Matt Hall
Monash University

Matt is an Australian Research Council (ARC) Discovery Early Career Researcher Award (DECRA) DECRA fellow and group leader in the School of Biological Sciences at Monash University.

Matt’s current research investigates the evolutionary genetics of life’s big challenges: sex, death, and disease. Central to these topics is an understanding of how energy is acquired, used, or exploited throughout a host’s life. Projects include understanding why hosts differ in their capacity to be exploited by a pathogen, how differences between the sexes in their condition and energy use influence the evolution of disease, and does the energy efficiency of a host or pathogen influence its rate of spread during an invasion.

Dr Christen Mirth
Monash University

Christen is the Head of the Developmental Responses to Environmental Change Research Group in The School of Biological Sciences at Monash University.

Christen is interested in understanding the molecular mechanisms that underlie environmentally- and genetically-induced variation in body size and shape.

Alex Gangur
Monash University

Alex is a PhD candidate. He is broadly interested in how natural populations and communities respond to change using both experimental and modelling approaches, and extracting actionable insights from this work for policy.

Alex will be experimentally evolving harpacticoid copepods (Tisbe sp.) to evaluate the eco-evolutionary response to food-rich and food-poor environments. He will couple this experimental work with integral projection models to predict future population dynamics.

Emily Richardson
Monash University

Emily is a PhD student interested in understanding the ecological and evolutionary consequences of particular life history strategies. Most animal species develop via complex life cycles, passing through stages to reach maturity.

Emily’s PhD aims to investigate the evolution of complex life histories and whether ecological factors can predict when and why life history transitions occur.

George Jarvis
Monash University

George is a PhD candidate interested in the effects of larval experience on adult performance.

For animals with multiple life stages, traits that benefit larval success are not always beneficial in later stages of development.

By comparing life history strategies among animals that differ in their developmental mode, George aims to identify the evolutionary mechanisms that facilitate ontogeny throughout complex life cycles.

Sam Ginther
Monash University

Sam is a PhD candidate.

Broadly, he is interested in different life-history strategies and their effect on the evolution of biological communities.

Sam’s PhD research examines reproductive effort across taxa and the consequences it may have on the flux of energy in biological systems.

Belinda Comerford
Monash University

Belinda is a PhD candidate interested in optimising the aquaculture of micro- and macro-algae for human consumption.

The aquaculture industry is growing at a rapid rate, supplying much of the world with sources of food, feed stocks and high-value chemicals. As a relatively novel space, the aquaculture industry has immense potential for optimization.

Belinda’s PhD aims to explore experimental evolution can be used to enhance land-based aquaculture processes to produce desired traits and molecules at sustainable and productive rates.

Ashley Potter
Monash University

Ashley is a PhD candidate interested in the causes and consequences of metabolic rate in sperm.

All metazoans reproduce sexually using sperm which means that they are extremely abundant. Sperm fulfils essential roles in reproduction and offspring success meaning they are not biologically inert as once thought.

The aims of Ashley’s PhD are to take a macroevolutionary approach by looking at interspecific variation of sperm metabolism as it scales with size, and
take a microevolutionary approach by investigating selection on metabolism as it covaries with other traits in several broadcast spawners.
