Bio: Dr. Annamalai earned his Doctoral degree in Chemical Sciences from CSIR- Central Electrochemical Research Institute(CECRI) and Academy of Scientific and Innovative Research (AcSIR),India in 2017. His research is focused on removal of organic and inorganic contaminants from reactive dye textile effluent-contaminated agricultural soil using the electrokinetic process. Following that, he worked as a Postdoctoral researcher in Environmental Engineering at Dong-A and Kyungpook National University (KNU), South Korea. During his time at KNU, he focused on developing colloidal activated carbon and biochar as metal-free catalysts for in-situ chemical oxidation of contaminated groundwater and soil using persulfate-based advanced oxidation process. His research interests also include exploring metal or metal-free carbonaceous materials for treating PFAS-contaminated groundwater and soil. 
Research Topic: Soil and groundwater treatment, Advanced oxidation, Wastewater treatment, Electrochemistry, Carbonaceous materials, Industrial waste management.
