(Hong Kong, 2022)
An ecologist working on ecosystem dynamics, nonlinear time-series analysis, environmental DNA, and microbial community. Currently focusing on ocean ecosystem.
Announcement and Schedule
Ushio-ecolab webpage at HKUST is HERE!
We are studying ocean ecosystem dynamics at The Department of Ocean Science (OCES), The Hong Kong University of Science and Technology (HKUST). Please contact me (ong8181 [at] gmail.com) if you are interested in performing ocean research using environmental DNA analysis and statistical modeling in Hong Kong.

We published a new paper. We performed an intensive and extensive field monitoring in an experimental rice plots in 2017, and obtained eDNA-based daily time series of ecological communities. Based on time series analysis, we detected organisms influencial for rice growth under field conditions, and validated the statistical results by a field manipulation experiment in 2019. This demonstrates the potential of an ecological network-based approach for detecting organisms useful for agriculture under field conditions.
