I 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 policymakers 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 “wannabe” ecological modeler with a great interest in linking hydrology with ecosystems using multidisciplinary approaches. 😉

My name is Cory Yap and I am an environmental researcher at the University of Hawaiʻi at Mānoa and outreach education coordinator at ʻIolani School. My time is split into being an aquatic biologist, doing environmental outreach with K-12 students, deploying/maintaining wireless sensor networks for environmental monitoring, and web design. In my spare time, I enjoy kayak/shore-fishing, canyoneering, hiking, free-diving, photography and gardening.

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 is 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.

Derek Esibill ran operations of oceanographic research vessels for 10 years, before teaching science for the Hawaiʻi department of education where his students were engaged in research projects investigating correlations between age, bacterial infection, and age on coral tumors; and water quality in the Hamakua and Kawainui marsh systems. He is now the director of the Pacific American Foundation’s research and education program, Watershed Investigations, Research Education, and Design (WIRED). A program that engages 6th-12th grade students in current, ongoing, leading edge research investigating the impacts of land management practices on watersheds and the associated coral reefs. Derek is also PAF’s technology coordinator, network administrator, STEM coordinator, and NALU Studies science and engineering teacher. He has a love for all things ocean. Currently he is a Masters Plan C student at the University of Hawaiʻi in Natural Resources Environmental Management Hydrology Lab, directed by Yin-Phan Tsang.

Me in PH

I am a practitioner of aquatic ecology with experience in aquatic bioassessment, wetland conservation and restoration, fishing surveys and regulations as well as Environmental DNA and community ecology and composition. My current M.S. thesis is titled: Nearshore and Estuarine Biodiversity of Pearl Harbor, Comparing Traditional Sampling to Environmental DNA (eDNA). My new interests are advocating for advances in geen infrastructure (GI), stormwater management and supporting Ahupua’a management systems in Hawaii.

Aloha, I am a MEM graduate student in the Department of Natural Resources and Environmental Management at UH Mānoa. My interests are in land and water management, specifically looking at sedimentation run-off during a storm in the Ala Wai Watershed. From my research I hope to better understand how watersheds work on the island of Oahu and how to improve the water quality for the streams in the watershed.

Aloha, I am completing a Masters of Environmental Management in the Department of Natural Resources and Environmental Management at UH. I am concentrating on Land and Water Management, specifically here on the island of Oahu. I currently volunteer with the Sierra Club and helping with the Ala Wai Canal Project.

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.

Ayron M. Strauch

I am a research scientist in the Department of Natural Resources and Environmental Management at the University of Hawai‘i Manoa, where I am currently studying climate change impacts on the hydrological and ecological functioning of tropical watersheds. My research interests are focused on how spatial patterns in water resources interact with the biological, geological, and social environment. Recent projects have included modeling and monitoring stream flow, soil erosion, and carbon exports, studying land-use impacts on water quality, and identifying how climate change will impact spatial patterns in the functioning of freshwater ecosystems among the Hawaiian islands.

Past research interests have examined water resources and water use impacts on freshwater and terrestrial ecosystems in East Africa, the consequences of fire management on invasive vegetation, and marine ecosystem responses to sea-surface temperature hot-spots.
