Dr. Lakshmi VADDADI

Senior scientist

Lakshmi Prasanna completed her Ph.D. from VIT University, Vellore. Her graduate research is “Nanocrystalline ZnO, ZnO2 and its Polymer Composites: Synthesis, Characterization and Environmental Remediation”. She joined as TAU postdoctoral fellow in 2018 in the Water research center. In 2021 she joined as a senior scientist, head of the technological unit in Water research center.

Her research interests include:

  • Fabrication of photochemical filters based on nanomaterials for disinfection and degradation of micropollutants in water.
  • Understanding degradation pathways of Persistent Organic Pollutants (POPs) by Advance Oxidation Process (AOPs) and in natural environments.
  • Nano-fabrication of carbon-based aerogel for degradation of POPs and disinfection.
  • Antimicrobial high-touch surfaces using photocatalytic transparent films (metal oxide/metal peroxide)
  • Developing AOPs for degradation of pharmaceuticals in wastewater.
  • Translating developed AOPs from lab scale to pilot scale.
