Yuka Muto

Visiting Ph.D. student

Yuka's research focuses on the interaction between human activity and the environment within river basins. Her main research topic is the characteristics of the forestry situation such as systems and the scale of forestry operation in different regions, and how that affect the environment of river basins in Japan. She analyzes the relationship focusing mainly on the geological and topographical differences of river basins. She is also concerned with research topics such as the population trend around frequently flooded areas, and assessment of the impacts of both climate change and land use change to the water environment.

Yuka received her B.S. and M.S. in Civil Engineering from University of Tokyo, Japan, and is now a PhD student at the same department.

Spencer Lacy

Master's Student

Spencer is a master’s student in Berkeley’s environmental engineering department. With a river-centric upbringing, Spencer has been studying fluvial systems, river hydraulics, and hydrology since he could hold a paddle in his hands. His life revolves around the river; being in it, bringing it into people’s lives, protecting and restoring it, and making it accessible and enjoyable for all. Spencer’s research interests lie in human interaction with rivers and the benefits it can lead to as well as ubiquitous low-head dams and the immediate public safety hazard that they present. Before coming to Berkeley, Spencer worked in Colorado as a design engineer and project manager designing whitewater parks, river waves, in-stream and bank restoration, dam modification, and greenways that connect communities to their river corridors. Spencer is also a passionate and accomplished whitewater athlete.

Jennifer Natali (and Dom)

Jennifer Natali

Ph.D. Candidate

Jen's research explores interactions of sediment, water, and vegetation in montane meadows of California's Sierra Nevada.  Through field observation, remote sensing and numerical models, she works to improve our understanding of the geomorphic and hydrologic processes that influence the ecological function of meadows. By understanding driving factors of ecosystem resilience, we can better prioritize restoration investments and apply techniques to sustain meadow ecosystems and understand their role as hydrologic refugia with climate shifts. Jen earned a B.A. from Smith College. After working as a software engineer for ten years, Jen sought an M.L.A. from UC Berkeley and now works toward a Ph.D. that will inform management of watershed, river and ecosystem functions.

Celina Balderas Guzman

Ph.D. Candidate

Celina’s research interests focus on urban stormwater landscapes, particularly constructed wetlands. Stormwater pollutes thousands of miles of rivers and streams, along with lakes, bays, and estuaries. It also poses flooding risks. Because climate change is exacerbating the intensity of storms, greater volumes of stormwater are in our future. Celina’s research attempts to find solutions for urban stormwater by bringing together landscape design, planning, and environmental engineering. Previously, she led a two-year, funded research project at MIT that explored new forms of stormwater wetlands and ponds that merge hydrologic, ecologic, and urban functions. She has three degrees from MIT in architecture, urban planning, and urbanism.
