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.
