Associate Professor

Dr. Badireddy and his research group conducts interdisciplinary research on: (1) sustainable membrane processes with the focus on water & wastewater treatment, and resource recovery, (2) environmental nanotechnology with the focus on applications and implications of engineered nanomaterials, and (3) nanometrology with the focus on developing enhanced darkfield-hyperspectral imaging (ED-HSI) microscopy methods for detection and quantification of engineered nanomaterials and co-contaminants in environmental and biological matrices.

His latest projects include studies on fate and transport of per-and poly-fluoroalkyl substances (PFAS) in environmental systems, development of green nanomaterials and nano/membrane composites for PFAS remediation, innovative membrane anti-fouling strategies, bio-electrochemistry in biofilms on natural and engineered surfaces, and phosphorus removal and recovery strategies.
