• Performed qualitative and quantitative analysis of raw material, API, finished product, stability, process validation using analytical instrumentations such as HPLC, UV/VIS spectroscopy, pH meters, analytical balances, USP dissolution apparatus.• Implemented the analytical method evaluation, method development, method validation (Linearity, Precision, Recovery, Specificity, LOD, LOQ, Forced Degradation, Robustness, etc.) and method transfer of excipient, raw material, API and finished product.• Drafted and edited method validation protocols/reports, method transfer protocols/reports, and analytical methods.• A broad conversance with chromatographic analysis such as resolution, tailing factor, peak purity, and theoretical plate count of chromatographic peak. • Experienced in method development challenges, instrumentation troubleshootings and routine LIR investigations. • Had fundamental understanding of GxP, cGMP’s/ cGLP’s and USP/NF compendial monograph.• Complied with cGMP and SOP requirements.• Maintained laboratory notebook as per the FDA regulation and cGMP’s requirements.

My research focused on the mass spectrometric studies:• Coupled liquid sample desorption electrospray ionization mass spectrometry (DESI-MS) with a cartridge column to achieve desalting and pre-concentration of trace amount of drugs, peptides, and proteins from complex matrices which largely reducing the difficulty of analysis of “dirty sample ”.• Devised magnetic graphene framework/nanoparticles for magnetic solid-phase extraction (MSPE) and to achieve high efficiency pre-concentration for drugs of abuse detection in forensic science.• Developed novel methodology for shotgun proteomics by using a homemade immobilized tryptic column coupled with DESI-MS for fast online protein digestion (within minutes).• Monitored the methanol electro-oxidation by using DESI-MS for elucidating a fuel cell reaction and screening ideal fuel cell electrode materials.• Monitored enzymatic kinetics by time-resolved DESI-MS.
