Harold W. Walker's work centers on water and wastewater treatment technologies, including membrane systems, nitrogen removal biofilters and septic systems, and methods for managing harmful algal blooms and their toxins in drinking water. He also contributes to work on advanced construction materials such as cellulose-reinforced geopolymer composites. His research combines engineering design of treatment systems with environmental chemistry and microbiology to address contaminant removal and water quality.
Publication output has fluctuated over the past decade, rising to a peak in 2020, dropping sharply in 2022-2023, then surging again in 2024, suggesting an uneven but currently active publication pace.
