Professor of Environmental Science and Technology (ENST) & Asso. Dean for Research & Asso. Director of Maryland Agricultural Experiment Station (MAES), University of Maryland College Park; Also Affiliate Faculty with Fischell Department of Bioengineering, Dept. of Civil and Enviro. Engineering, and MEES (Marine Estuarine Environmental Sciences).
Dr. Shirmohammadi has cooperative project with USDA-ARS that supports watershed scale modeling in a CEAP project (nationally funded project) in Choptank watershed, Maryland. He is also an active participant and member of a multi-state project S-1042 (Watershed Scale TMDL Modeling). In addition, he has one Ph.D. student working on the relationship between incidences of human cancer and drinking water quality on spatial coordinate system using GIS in a Super Fund site. He actively participates in writing grant proposals, presentation of his research results in scientific conferences, and publication of his research results in refereed journals. As a Co-PI, he helped secure two large competitive grants in 2012, one from US-EPA in the amount of about $700k for 3 years and the other from USDA-NIFA in the amount of $620k for 3 years. US-EPA project deals with the storm water management in urban and suburban ecosystems and the USDA-NIFA project deals with the sustainable management of agro-ecosystems. In both projects we are creating Diagnostic Decision Support Systems (DDSS) for sustainable management of landscape using community empowerment and education. Also, in both of these projects we are using watershed models to assess the hydrologic patterns.
Teaching senior and graduate level courses in the area of soil and water engineering flow through porous media, numerical modeling, advising and mentoring undergraduates with respect to scheduling, progress, and career opportunities. As the Director of the Bioengineering Undergraduate Program, Dr. Shirmohammadi coordinated undergraduate program with respect to curriculum development, course offerings, recruitment, and ABET accreditation. Research projects included experimental and theoretical evaluation of the hydrologic and water quality responses of agricultural watersheds, TMDL assessments, design of water table management systems and the impact of various agricultural management practices on water quality, overall watershed management, and ecosystem and human health.
Theoretical work has involved developing mathematical vadose zone models to predict water and contaminant transport, and applying/modifying existing models (CREAMS, GLEAMS and PRZM) for assessing the impact of agricultural management practices on surface and ground water quality. Preferential and macropore flow characterization and coupling nonpoint source pollution models with Geographic Information Systems (GIS) have been other research interests for Dr. Shirmohammadi. Evaluation of TMDL and associated uncertainties with TMDL models are outgrowth of his National Watershed Water Quality Modeling and Monitoring Project sponsored by US-EPA in last couple of years. In this regard, his group has also developed Decision Support System (DSS) to help forecast economic and environmental viability of alternate irrigation systems considering water as a purchasable commodity.
In last 5-6 years, Dr. Shirmohammadi’s research group has also been involved with modeling transport of biomolecules and pathogens in diverse porous mediums such as cells and ecosystem. His experimental research has involved laboratory, field, and watershed scale evaluations of the impact of agricultural management systems on nutrient, pathogen, and pesticide losses. Relating childhood cancer and all other cancer incidences and groundwater quality in Maryland has been another research area that Dr. Shirmohammadi has been involved. His research has graduated 14 Ph.Ds and 15 MS students since 1986, has produced more than 300 hundred refereed and conference publications, 1 reference book and several book chapters, trained multiple undergraduate students, and has attracted more than $5M in competitive and collaborative funding.

Hydrology and Water Resources Engineering Laboratory provides state-of-the-art support in simulating the natural hydrologic conditions by using a 30-ft flume, a rainfall simulator, a hydrograph tank, and a drainage/water table management tank. This lab supports both research, senior capstone, and teaching hydrologic principles. This Lab is coordinated by Dr. Adel Shirmohammadi, but he welcomes its use by other colleagues by appointment. It should be noted that this lab is also capable of performing soil particle size analysis and determination of soil hydraulic properties including soil water characteristic curve (i.e., tension curve) and soil hydraulic conductivity.
