Research and Teaching Interests
Development of analytical methodologies for speciation
of environmental pollutants using electro-analytical techniques
and spectroanalytical techniques. Modern votammetric techniques
based on diffusion control mass transfer (e.g. linear
sweep, differential and normal pulse, square wave voltammetry)
and convection controlled mass transfer (e.g. rotating
disk electrode voltammetry) are used for speciation of
analytes at sub parts per billion level concentrations.
Analysis of errors associated with calibration of analytical
instruments and investigation on extending dynamic range
of calibration curves.
Mechanistic investigation of electro-deposition process
associated with fabrication of semiconductor materials
used for manufacture of solar cells. Use of the knowledge
for fabrication of semiconductor materials based on CuInTe
and CdTe/CdS systems.
