Aurora Kagawa-Viviani is currently an assistant professor at the University of Hawaiʻi Water Resources Research Center and at the UHM Department of Geography and Environment. She earned her PhD in Geography from UH Mānoa focused on ecohydrology, and holds an MS Botany (UH Mānoa) with an Ecology, Evolution, and Conservation Biology specialization and an SB Environmental Engineering (MIT). Aurora’s research applies the lens of change to study interactions and feedbacks between communities (plant and human) and hydrologic processes. Her current research themes include ecohydrology of biotic invasion and ecological restoration and community-responsive water research supported through collaborations with social scientists exploring the intersection of socio-hydrology, hydrosocial paradigms, and participatory and Indigenous research. Dr. Kagawa-Viviani is excited to engage with the aspirations of local communities to drive rigorous and novel research in the transdisciplinary space encompassing plants, water, and people.

Matthew Widlansky is the associate director of the CIMAR-UH Sea Level Center and an affiliate researcher in the Oceanography department. He received a Ph.D. from the Georgia Institute of Technology in Earth and Atmospheric Sciences, with a focus on understanding climate variability in the tropical South Pacific. Matthew currently researches sea level variability on seasonal, interannual, and longer timescales. He uses global climate models of the ocean and atmosphere to assess the limits of predicting coastal impacts from sea level extremes.

Yinphan Tsang, PhD Yinphan Tsang is an Associate Professor in Natural Resources and Environmental Management in University of Hawaiʻi at Mānoa, and currently a Visiting Erskine Fellow in Civil and Natural Resources Engineering, University of Canterbury in New Zealand. She is trained as surface hydrologist with a great interest in understanding the island hydrology and linking hydrology with ecosystems using multidisciplinary approaches. She investigates hydrological processes and their implication in fluvial ecosystems. Her lab actively investigate five focus research topics – 1) Extreme weather and flood, including trends in extreme rainfall and streamflow and their association with antecedent conditions; 2)Hydrological modeling, applying WRF-Hydro, Next-Gen National Water Model, and SWAT model to management and extreme climate; 3) Watershed Assessment, including habitat assessment, using stream monitoring data to evaluate management impacts; 4) Aquatic Biodiversity, including investigation with traditional field survey and eDNA meta-data analyses; 5) Conservation Prioritization, including aquatic landscape analysis and education outreach.
