We INTEGRATE hydroLOGY, ecologY, and ENGINEERING TO STUDY WICKED PROBLEMS AND SOLUTIONS IN watersheds around the globe. To that end, we combine hydro-ecological observations with mathematical models, Geographical Information Systems, and remote sensing technology.

Who are we?

Based in the Department of Civil and Environmental Engineering at the University of South Florida, we are a group of engineers and scientists interested in watershed sustainability solutions

Principal Investigator

Mauricio E. Arias, PhD, PE

Growing up in the Colombian Andes, Mauricio thought he was going to be an anthropologist. Moving to Florida as a teenager opened his eyes to the world of ecology and engineering, and he has been navigating through those disciplines in his research in (sub-) tropical watersheds. After completing a BS and a ME in Environmental Engineering from Univ. of Florida, Mauricio moved to New Zealand to do his PhD in Civil Engineering at the University of Canterbury. He returned to the US in 2014 for a postdoc in Sustainability Science at Harvard, before arriving to USF in Fall of 2016.

She is currently investigating research opportunities in coral reef restoration and ecosystem – based coastal defense. Megan is a NSF-NRT STRONG Coasts Fellow.

Cody Stewart, MS (PhD in Civil Engineering expected in Spring 2024)

Cody’s work is on stormwater infrastructure, more specifically the evaluation baffle box and wet detention pond performance across the city of Tampa. He earned his M.S. in environmental horticulture with a minor in soil and water science from the University of Florida in 2018. His research at UF focused on the impact of nursery production practices on herbicide efficacy. Cody earned his B.S. in biology with a focus in ecology, conservation, and environmental biology with a minor in regional planning from the Indiana University of Pennsylvania in 2016. As a McNair Scholar, Cody conducted undergraduate research on green roofs, where he evaluated the germination and survival of native Pennsylvania plants in a green roof setting. Upon graduating with his Ph.D. in civil engineering, Cody hopes to pursue a career in academia.

Sajad Soleymani Hasani, MS (PhD Civil Engineering-Water Resources expected in 2026)

To fulfill his long-standing love for nature and inspired by the degradation of Lake Urmia – one of the biggest salt lakes in the world – due to persisting droughts caused by global climate change and unsustainable management and consumption, Sajad joined the University of South Florida to pursue his Ph.D. in Water Resources aiming to play his part in the preservation of globally threatened water resources. Sajad’s research interests are hydrology, water quality modeling, and the application of state-of-the-art artificial intelligence models in hydrology. Currently, he is a part of a research project focusing on predicting and managing harmful algal blooms in the St. Lucie Estuary and Watershed – the estuary connecting Lake Okeechobee to the Atlantic Ocean.

Sophea Rom Phy, MS (PhD in Civil Engineering - Water Resources expected in 2027)

Phearom grew up in Phnom Penh, Cambodia, where he completed his Engineer’s Degree in Water Resources Engineering at the Institute of Technology of Cambodia in 2021. He went on to earn a MS in the same major at Kyoto University, Japan. His study regions started from a local tributary of the Mekong River to the Tonle Sap Lake Basin during his respective degrees. To realize his studies on the whole Mekong River Basin, he joined USF as a PhD student in the Fall of 2023. Phearom is currently a part of a project on subseasonal-to-seasonal (S2S) flow forecasting in the Mekong River Basin. His research interests lie in watershed hydrology, flood modeling, forecasting, and AI applications in water resources.

Tione Grant ( M.S. in Environmental Engineering expected Fall 2025)

Tione’s appreciation for the land and ocean can be traced to his childhood, from his birth in St. Kitts and Nevis to moving to the US Virgin Islands. He pursued a Bachelor of Sciences in Applied Mathematics at the University of Virgin Islands. In 2020, Tione transferred to University of South Florida to pursue a bachelor’s in chemical engineering and continued his research pursuit, working with municipal wastewater treatment systems and household drinking water treatment. With each topic, his master’s research focuses on stormwater management.
