I, Dr. Ramachandra is presently working as Lecturer in Chemistry Government College for Men, kadapa, India. I completed Ph.D. in Chemistry from Jawaharlal Nehru Technological University, Hyderabad, India. I pursued M.Sc., in Analytical Chemistry at S.K. University Campus, Anantapur, Andhra Pradesh. My research interests are Impurity Profiling of Drugs and Pharmaceuticals, Isolation and characterization of Impurities in drugs and Pharmaceuticals by HPLC, NMR and Mass Spectrometry, Stability studies and Degradation studies, Applications of Ionic Liquids in Chromatographic separation, Chiral shift Reagents for separation of Enantiomers by NMR Spectroscopy, and method development and validation of Drugs and Pharmaceuticals. I have published 15 research articles in international peer reviewed journals.

Area of Interest:

Molecularly Imprinted Polymers
Electrochemical Sensors
Ionic Liquids
