About us

We are a new research group at Single Molecule Science: the EMBL Australia node of the University of New South Wales. We are currently recruiting PhD students and postdocs. Please contact Scott if you are interested in joining or collaborating.



Scott Berry

Scott Berry

Group leader

Hi! I am Scott. After completing my undergraduate studies in Theoretical Physics and Biology at the University of Adelaide and the University of Western Australia, I moved to the UK for my PhD at the John Innes Centre. There, I worked with Caroline Dean and Martin Howard, combining theoretical and experimental biology approaches to understand mechanisms of epigenetic memory in Arabidopsis thaliana. I then moved to Switzerland as a HFSP postdoctoral fellow, working with Lucas Pelkmans at the University of Zurich. In Lucas’ group, I shifted model systems from plants to mammalian cells, and became immersed in the wonderful world of modern single-cell biology – focusing on understanding the mechanisms by which cells coordinate gene expression with cell size. Since October 2021, I have been a group leader at Single Molecule Science at the University of New South Wales.

I completed my undergraduate degree with majors in neuroscience and pharmacology. My PhD was undertaken at University of Sydney, working with Prof Macdonald Christie, during which I studied the pharmacology of opioid analgesics across in vitro assays and rodent behavioural studies. In the course of that work, I became interested in mathematical modelling of biological systems as a tool to unpick signalling mechanisms. As part of my PhD, I completed a research period at University of Nottingham, working with Prof Meritxell Canals. There, we sought to examine the kinetics of opioid receptor signalling on a population & single molecule level. As a result of this approach to receptor signalling systems, I have become increasingly interested in using similar techniques to systematically deconstruct other biological pathways.

Teddy Cheng Wei Kang

PhD student

Hello, I am Teddy. After completing my undergraduate in Resource Biotechnology at University of Malaysia, Sarawak, I continued my MSc in Molecular Medicine under Dr Oon Chern Ein at Universiti Sains Malaysia. This project involved collaborative work together with researchers at the Karolinska Institutet, aimed at determining if manic fringe protein expression can be utilized as a biomarker for therapeutics and prognosis in kidney cancer, as well as to determine its association with immune cell infiltration. Our research group also collaborated with the Weatherall Institute of Molecular Medicine to further elucidate the expression pattern of manic fringe in blood vessels of renal cancer and in tumor angiogenesis. I am currently a PhD student researching the global control of mRNA metabolism in human cells.

PhD student

Hi! My name is Bailey. I completed my undergraduate degree in Molecular Genetics and Biotechnology at Curtin University in 2021, studying honours under Ryu Takechi at Curtin’s Health Innovation and Research Institute. For my honours project I investigated the effects of Probucol on attenuating neurodegenerative changes associated with APOE4 genotype, using both in-vivo and ex-vivo analyses of transgenic mice expressing human APOE isoforms. I also worked on a murine model of traumatic brain injury where we established early neuropathological developments in the context of repetitive sub-concussion. Since beginning my studies I’ve always held a keen interest in cell biology, and I joined Scott’s group in 2023 as a PhD candidate, focusing on visualisation of transcription and mRNA processing in living cells.

We are interested in the mechanisms used by cells to regulate gene-specific and global RNA abundance – ranging from epigenetic memory and cellular decision-making to global RNA metabolism in the context of cellular physiology. We seek to generate a quantitative understanding of these processes.

Our research methodology is a combination of ’top-down’ (data-driven) and ‘bottom-up’ (hypothesis-driven) approaches. We make extensive use of high-throughput microscopy and automated image analysis, which enables detailed measurement of quantitative cellular phenotypes (for example, the abundance and localisations of specific proteins or RNAs) across large cell populations. Resulting datasets are then analysed using a variety of methods from data science. We complement these image-based approaches with functional genomics experiments, based on next-generation sequencing – providing exquisite genomic resolution, and use perturbation experiments including genome and epigenome-editing to test specific hypotheses.

Effects on gene expression of CRISPR-KO using smFISH

Projects in the lab are often underpinned by construction of minimal mathematical models at the molecular level, which we use as a tool for exploring possible explanations of experimental results and prioritising future experiments.

We believe that the best science happens in the overlap between fields. We strive to build a diverse team and foster collaborations across fields and disciplines.

Stability and plasticity of epigenetic memory

The chromatin of individual genetic loci can be set into molecular ‘states’ that control the expression of the underlying genes, and in some cases even instruct their own inheritance – acting as local epigenetic memory elements. When necessary, however, chromatin can also be reliably switched from one state to another – by processes that involve coordinated changes to the histone modifications, accessibility of regulatory sequences, and expression states of the underlying genes.

We are interested in the interplay between gene-specific diffusible regulatory factors (e.g. transcription factors), which tend to have continuous (analogue) control over gene expression, and heritable chromatin states (e.g. Polycomb-repressed chromatin), which tend to promote bi-modal (digital) stable expression states. To study these processes we use in vitro differentiation of epithelial cells from human induced pluripotent stem cells.

Integrating local and diffusible signals at chromatin Mechanistic model of self-perpetuating active and repressed chromatin states.

Global control of RNA metabolism

Mammalian cells coordinate RNA production rates with cell size to ensure RNA concentration homeostasis. We discovered that this process relies on adapting transcription rates according to nuclear mRNA concentration, so that overabundance of nuclear mRNA leads to transcriptional repression. This mechanism involves mRNA-based regulation of the activity of RNA Polymerase II, which in turn determines polymerase abundance. We are interested in further dissecting the interplay between the transcriptional machinery, nuclear RNA export and RNA degradation factors that act in concert to ensure robust mRNA concentration homeostasis.

Feedback from RNA production

High-dimensional cellular phenotyping

4i In recent years, technological advances have made it possible to visualise tens to hundreds of proteins in single cells. This has brought with it the ability to accurately quantify the high-dimensional relationships between protein abundances and their modification states, as well as the cell-to-cell variability of their subcellular localisation and co-localisation.

We use Iterative Indirect Immunofluorescence Imaging (4i) throughout our research to comprehensively evaluate changes to cellular phenotypes in the context of cellular differentiation and upon perturbation of RNA metabolism. These datasets are extraordinarily rich in information, however much of this information is not easy to interpret using existing approaches. In collaboration with Lucas Pelkmans’ and Fabian Theis’ research groups, we have developed a new computational image analysis workflow called CAMPA to facilitate analysis of these data across different perturbations, at the subcellular, cellular and population scales.

Consistent subcellular landmarks

Applying pixel-clustering approaches to highly-multiplexed 4i image data identifies subcellular structures in an unbiased manner. In this case, we focused on the nucleus: revealing organelles such as nuclear speckles, Cajal bodies, PML bodies and the nucleolus.
