David Schaad, Adjunct Assistant Professor and Assistant Chair

Dr. David Schaad has over twelve years of design and engineering experience as a consulting engineer working for various firms including: Parsons Engineering Science, Appian Consulting Engineers and Marshall Miller and Associates. He earned his B.A. from Denison University in 1990 with a double major in Physics and Mathematical Sciences and then matriculated to the University of Colorado in Boulder where he earned his M.S. in Civil Engineering in 1991. Following a number of years as a practicing engineer, he entered the graduate program at Duke University, where he earned his Ph.D. in 1998. He then returned to practicing engineering until his return to Duke University in 2003. As part of his experience, Dr. Schaad has: designed waste water treatment systems to address industrial and domestic waste streams; developed designs of storm water control structures and strategies to address water quality and quantity; designed fluid transport systems to replace water supplies impacted by anthropogenic sources; designed fuel transport and delivery systems; developed designs for commercial and residential development; prepared land use plans; developed designs to protect against potential flood hazards; designed and developed plans and specifications for fluid handling systems, waste mitigation alternatives and remedial actions for RCRA and CERCLA sites including active industrial facilities and inactive disposal sites (including NPL sites); conducted feasibility studies by evaluating and analyzing the economic and engineering considerations of multiple design alternatives; obtained extensive experience with innovative remedial techniques (including groundwater extraction and treatment, air sparging, soil vapor extraction, and bioventing). Current research focuses on water and wastewater treatment design, stormwater retention/detention and treatment design, hazardous waste remediation, urban hydrology, constructed wetland and stream restoration design, ecological stabilization, sustainable engineering in land development, water resources, water and wastewater treatment.
