Markus is an Associate Professor and an ARC Future Fellow (2021-2025). He serves on the Advisory boards for Polymer Chemistry and Macromolecular Rapid Communications. Markus is a Fellow of the Royal Australian Chemical Institute (FRACI), and the Higher Education Academy (FHEA) and was the Chair of the RACI NSW Polymer group from 2019-2022. He currently is the Associate Head of School (Research) in the School of Chemistry.

Qinqin Yang

PhD student

Qinqin received her B.Eng. in Pharmaceutical Engineering with Honors from Zhejiang University of Science and Technology in China in 2021. Subsequently, she finished a M.Sc. degree in Pharmaceutics from the University College London (UCL) in the U.K. in 2023, with elective courses in nanotechnology. In 2024, she started her PhD program at the University of Sydney in PNG group. Her research focuses on synthesising new polymer nanocomplexes for targeted CRISPR/Cas9 delivery in plant and fungal cells, contributing to the cutting-edge field of precise delivery of gene editing tools. Her research project involves close collaboration with the Jones lab in SOLES, promising a dynamic and interdisciplinary approach to her studies.

Dr Hoaxiang Zeng

Postdoctoral Researcher

Haoxiang received his B.Sc. in Polymer Materials and Engineering from Taiyuan University of Technology in 2016 and M.Sc. in Industrial Chemistry from the National University of Singapore (with Prof. Li Jun) in 2018. He then worked at the Max Planck Institute for Polymer Research as a research assistant (with Prof. Tanja Weil) in 2019. In 2024, he completed his PhD at the University of Sydney supervised by A/Prof. Müllner, studying stimuli-responsive polymer self-assemblies. He rejoined our team as a postdoc working on injectable hydrogels in 2025.

Ping Zeng

PhD student

Ping received her B.Sc. in Chemical Engineering and Industrial Biological Engineering from Dalian University of Technology in 2020. She then completed her M.Med. in Pharmacy at Shanghai Jiao Tong University in 2023 under the guidance of Prof. Shengrong Guo, focusing on developing drug delivery systems in cancer therapy. With an interest in nanobiomedicine, Ping worked as a research assistant within A/Prof. Lu Zhang’s group at the Southern University of Science and Technology, designing transformable peptides against tumor metastasis. In 2024, she commenced her Ph.D. at the University of Sydney supervised by A/Prof. Markus Müllner, studying on functional polymer nanodiscs for nanomedicine applications. Ping’s studies are supported by a postgraduate scholarship from the University of Sydney.

Chenyou Zhang

PhD student

Chenyou graduated with a combined Bachelor of Engineering (Biomedical) (Hons I) and Bachelor of Science (Chemistry) from the University of Sydney in 2021. During his Honours year, he worked under the supervision of Prof. Marcela Bilek in a collaboration with Dr. Markus Müllner, and focussed on producing an antibiofouling surface combining an ion assisted plasma polymerised coating and molecular polymer brushes. He then joined the PNG as a PhD candidate to develop molecular polymer brushes as part of advanced functional materials. Chenyou’s studies are supported by a postgraduate scholarship from the University of Sydney.

Dr Xinyi Zhang

Postdoctoral researcher

Xinyi graduated from the University of Electronic Science and Technology of China with a Bachelor of Engineering in Applied Chemistry in 2018. During her senior year she studied the synthesis and properties of polyethylene glycol-b-polybenzyl threonine polymers under the supervision of Prof. Jianyuan Hao. Having an interest in organic and polymer chemistry, she joined the PNG as a Master of Philosophy student to work on new carborane-containing polymers. Her project is in collaboration with Prof. Lou Rendina's group.
