Snigdha Praharaj is a postdoctoral associate with Professor John Weidner and Professor Christopher Williams in the Department of Chemical Engineering at the University of South Carolina. Her Ph. D. dissertation, under the direction of Professor Tarasankar Pal was on the synthesis, characterization and catalytic application of metal nanoparticles. Her research interests include:

• Synthesis of semiconductor nanoparticles and their optical properties

• Surface functionalization of nanoparticles and their applications in sensors

• Optical properties of metallic nanoparticles

• Recycling and recovery of metal nanoparticles

• Catalysis by mono- & bi-metallic nanoparticles

• Photophysical properties of fluorescent probes on the surface of metal nanoparticles

• Application of metal nanoparticles in surface enhance Raman scattering (SERS) studies
