GREENING LAB | ABOUT US
Established in July 2016, the Greening Lab is based in the School of Biological Sciences of Monash University in Melbourne, Australia. We are an interdisciplinary team of microbiologists, biochemists, and ecologists who are working together to understand the survival strategies of environmental and pathogenic bacteria.
Group Leader: Associate Professor Chris Greening
Chris became fascinated by the versatility of bacteria since his undergraduate teachings at the University of Oxford. Following a first-class Honours research project, he undertook a doctorate down under investigating the physiological roles of the hydrogenases in Mycobacterium smegmatis. He then gained postdoctoral and lecturing experience at the University of Otago, CSIRO, and the Australian National University. In 2016, he was appointed as a group leader in Monash University and was later awarded a prestigious ARC DECRA Fellowship. Trained in the fields of biochemistry and microbiology, Chris also has experience in genetics, microbial ecology, and molecular evolution. Away from the lab, he enjoys playing piano and saxophone, trying to stay fit, and getting taken for long walks by his two dogs.
Postdoctoral Fellow: Dr Eleonora Chiri
Ele is an early-career scientist interested in soil microorganisms. Trained as environmental microbiologist, she obtained her doctoral degree at ETH Zurich on methane-oxidising bacteria in 2016, then gained postdoctoral experience at Charles Darwin University and the University of Melbourne. Since late 2017, Ele has collaborated with the Greening Lab on microbial methane and hydrogen oxidation processes in Australian termite mounds and savanna soils, among other projects. She has been awarded a postdoctoral fellowship by the Swiss National Science Foundation which will keep her busy investigating the ecological role of trace gas scavenging in oligotrophic soil ecosystems. During her spare time, she keeps busy with cooking, hiking, and practicing yoga.

Postdoctoral Fellow: Dr Rhys Grinter
Rhys is microbial biochemist and a card-carrying structural biologist, who likes to use diverse approaches to investigate bacterial form and function. His current research interests include: bacterial metabolism, membrane biogenesis and iron scavenging. He did his PhD at the University of Glasgow in Scotland, investigating antibiotic proteins produced by bacteria for intraspecies competition, a.k.a. How bugs kill bugs. In 2015, he moved to Monash University on a Wellcome Trust research fellowship on protein import in bacteria. He joined the Greening lab in 2018, where he is, among other things, investigating F420 biosynthesis. Outside of work, he enjoys cooking, travelling, scuba/free diving, fishing and riding his bike.

Postdoctoral Fellow: Dr Rachael Lappan
Rachael has come from the human microbiology field, completing her PhD in 2019 at the University of Western Australia on the microbiome of childhood ear infections. Excited to explore the universe of environmental microbiology, she joined the Greening lab in the same year to work on the RISE program. In RISE, she is using culture-independent methods to monitor the prevalence of gut pathogens in both humans and the environment during the trial of an improved water and sanitation intervention in Indonesia and Fiji. When not at work she enjoys hosting board game nights, playing video games, cross-stitching and looking at photos of other people’s dogs.
Lab Manager: Tent (Thanavit) Jirapanjawat
Tent is the full-time research assistant, lab manager, and occasional dog-sitter for the Greening Lab. A graduate of the Australian National University, he did a BSc in Biology and an Honours in Chemistry. During Honours, under Chris’ co-supervision, he studied substrate promiscuity of F420-dependent enzymes in mycobacteria, resulting in three publications. At the Greening Lab, he is currently involved in a range of projects in the ecology and physiology spaces. In his spare time, he enjoys badminton, playing acoustic guitar, and cooking.
PhD Student: Helena (Ya-Jou) Chen
Helena’s PhD centres on understanding the physiological and ecological roles of H2 metabolism in marine ecosystems. A graduate from the China Medical University in Taiwan, her Master’s thesis was titled “A comparative study of the interaction of Bartonella henselae strains with human endothelial cells”. She subsequently made the switch from medical to environmental research by working as a research assistant for three years at the National Taiwan University and National Sun Yat-sen University. In these roles, she investigated the ecophysiology of freshwater microorganisms and marine invertebrates, resulting in multiple publications.
PhD Student: Sean Bay
Sean is investigating microbial biodiversity and primary production in global desert ecosystems. After completing his Honours in Evolutionary Biology at the University of Exeter, he spent time working as an environmental field officer down under. He thereafter completed a Masters in Environmental Monitoring, Modelling and Management at King’s College London, learning computer and field based techniques to query environments undergoing change. Sean has also worked on ecological restoration and monitoring projects within the context of environmental rehabilitation and agriculture. He enjoys surfing, mountain biking and playing violin.
PhD Student: Zahra Islam
Zahra’s PhD centres on understanding the determinants of trace gas scavenging in mycobacteria. During her first-class Honours project in Microbiology at UNSW, she characterised the effects of sponge symbiont-derived eukaryotic-
PhD Student: Paul Cordero
Paul is focusing on the hydrogenases and carbon monoxide dehydrogenase in the mycobacterial respiratory chain. After earning his Master’s degree in Microbiology at the University of Santo Tomas, Philippines, he worked as a Research Associate at the Biochemistry and Molecular Biology Laboratory of the University’s Research Center for the Applied and Natural Sciences. He then joined the Microbial Biochemistry Laboratory at the University of Marburg, Germany as a Research Assistant where he continued to develop research skills in molecular biology and biochemistry. In his free time, he enjoys cooking and having slow-paced but long walks.
