Dr Saleh’s research focuses on environmental implications and applications of nanomaterials. His lab studies nanomaterial fate and transport and evaluates mechanisms of nano-bio interaction on the implication aspects, while develops novel nano-enabled technologies for water treatment applications. Recent projects include: studying fundamental aggregation and deposition behavior of carbon nanotubes, anisotropic gold-nano particles, indium tin oxide, and conjugated nanohybrids; development of nano-enabled disinfection technology that harness the power of microwave irradiation; dispersion control of nanotubes for construction materials (cement and asphalt); and nano-education. His research has produced 73 publications in refereed journals and 8 book chapters with more than 6500 citations. Dr. Saleh is one of the Editors of Journal of Hazardous Materials, one of the top environmental science and engineering journals with an impact factor of 7.65. At the undergraduate level, Saleh teaches the “Introduction to Environmental Engineering” and two newly developed courses on nanotechnology: “Designing Sustainable Nanomaterials” and “Nanotechnology Laboratory” (co-taught with Dr. Kirisits). At the graduate level, he teaches a newly developed course, titled: “Environmental Implications of Nanotechnology”.
