tsang_yin-phanI am an ecological modeler with a great interest in linking hydrology with ecosystems using multidisciplinary approaches. I investigate surface and subsurface water processes and their implication in fluvial ecosystems. I use varied statistical and modeling techniques to combine disparate spatial and ecoinformatics datasets, validated with field measurements, to describe complex interaction patterns between biotic and abiotic processes contributing to ecosystem services. I build ecological predictive models to better address fluvial habitat degradation under anthropogenic and climate change. Knowing the interaction between ecosystems and their adjacent environments is not only a profound knowledge itself and is informative to policy makers and natural resources managers in order to conserve sustainable water resources and to preserve functional aquatic ecosystems. My ultimate goal is to advance our knowledge to achieve a balance between development and sustainable ecosystems.

I am a postdoc in the Department of Natural Resources and Environmental Management at UH. My research here focuses on the impacts of changing climate on Hawaii’s aquatic ecosystems.

My background is in wetland hydrology, biogeochemistry and ecology. My research interests focus on advancing the understanding of hydrological processes (e.g. surface water-groundwater interactions) in wetland environments, and their consequences on ecological functioning, including: the influence of differing hydrological regimes on wetland species, nutrient cycling in stream sediments and riparian zones, and the assessment of anthropogenic pressures (e.g. river engineering, climate change) on wetland health.

During my post-graduate studies and work as a research scientist I have been involved in a number of diverse multidisciplinary water research projects, ranging in scope from large arctic glacial rivers to small temperate streams. My master’s research addressed the importance of river hydrology and flooding for regulating floodplain biogeochemistry. My Ph.D. assessed the significance of enhancing surface-subsurface interactions, i.e. hydrological connectivity via river restoration (embankment removal), on floodplain functioning. I am interested in the use of physically-based hydraulic and hydrological models to simulate wetland processes and anthropogenic disturbances on floodplain ecosystem services (e.g. flood water storage, biodiversity, and water quality), which can provide a quantitative framework to guide the protection and management of water environments.

Aloha, I’m a Ph.D. student in the Department of Natural Resources and Environment Management at UH. I focus on hydrology. My research interests are how floods occur; how can we explain streamflow by modeling; what the trend is in peakflow and how it associated to rainfall trend in Hawaii. Besides I’m curious about how streamflow impact stream ecology and the relationship between atmospheric condition and low flow. I’m also a non-professional body surfer and hula dancer.

I am a M.S. student in the Department of Natural Resources and Environmental Management at the University of Hawai’I at Manoa. My research interests include a focus on watershed analysis using modeling and mapping. I would like to explore ways to use water more efficiently as a resource while minimizing contamination and preserving the environment around it.

Aloha, I am originally from the small town, Norwich in Upstate New York, but have been living in Hawai`i since 2005, so over 13 years now. I am currently aiming to get my Master’s Degree in Geology & Geophysics (newly renamed “Earth Science”) here at UH Mānoa, with a focus in Hydrology. As with my undergraduate thesis in Global Environmental Science, I am continuing my studies of groundwater contaminant transport in a small watershed in American Samoa called Faga`alu. I have been estimating pesticide and nutrient fluxes through a groundwater transport model I have built over the past few years. My main interests are of course hydrology, hydrogeology, contaminant transport, water quality, submarine groundwater discharge in coastal regions, and environmental science. I have also held an internship with Honolulu’s Stormwater Quality Branch to get some experience in more urban-focused water studies as well. I look forward to graduating and finding a position in government or industry, hopefully in the Pacific Northwest.
