Dr Ryo Sekine


Dr Ryo Sekine is a Senior Lecturer in Chemistry at USC Moreton Bay, a physical chemist and an environmental spectroscopist. He has a Ph.D. in Chemistry from Monash University (2012) and has broad interests in the application of analytical and spectroscopic methods to investigate and address environmental challenges.

Prior to commencing at USC, Dr Sekine was a Research Fellow at Griffith University where he examined the geochemistry of vanadium in the marine environment using chemical and spectroscopic (XAS) methods. He also developed expertise in physical, chemical, analytical and toxicological aspects of environmental nanoscience in Australia (Research Associate, UniSA) and in the United Kingdom (Marie Skłodowska-Curie Fellow, NERC-CEH, now UKCEH), and he maintains valuable networks in both areas of research.

More recently, he has expanded his interests into understanding the impact of climate change on soil nutrients and chemistry through collaborations with colleagues in the UK and Germany.

Dr Sekine has strong interests in the application of synchrotron-based infrared and X-ray techniques in the areas of nanoscience, soil science and geochemistry. He has a unique combination of experiences that span multiple spectroscopic regimes, and his goals are to utilise these strengths to develop an advanced spectroscopy program, including synchrotron-based methods, that becomes a focal point for analytical solutions to the university and the region’s environmental and industrial challenges.

Applications of advanced spectroscopic methods towards unravelling the micro and nanoscale chemistry during enhanced weathering

Dr R Sekine (Lead), Dr B Sarkar (CI, Lancaster), Prof DJ Beerling (CI, Sheffield)

Royal Society of Chemistry, £5,000 ≈ A$9,200


Enhanced weathering (EW) is a carbon dioxide removal (CDR) strategy where soils of managed croplands are amended with crushed fast-reacting silicate rocks. There are several nanoscale mechanisms that are hypothesized to facilitate CDR ad stabilise carbon. This project investigates these mechanisms during EW with a combination of advanced spectroscopic methods.

Nanomaterial surface interactions at the molecular level and their impact on ecotoxicity

European Commission, €183,455 ≈ A$296,800


As a Marie Sklodowska-Curie Fellow, I investigated the molecular interactions occurring at the surface of engineered nanomaterials (ENMs) in environmental matrices. In addition to a spectroscopic method, a multimodal imaging method was developed multiple partners in the UK.
