Accomplished, results-oriented professional interested in working in a bio-analytical research field. Expert in the structural characterization and quantitation of proteins, glycans, lipids and small molecules using cutting edge mass spectrometric techniques. Demonstrated experience in chromatographic method development/validation for pharmaceutical drugs, drug intermediates, raw materials under GLP/FDA regulations.

I am a highly motivated bioanalytical scientist with hands on experience in research and managing complex interdisciplinary team projects focused on proteomic methods and technology development for research in life sciences. My doctoral research involves the development of 157 nm photofragmentation technique for the first time to glycans/lipids structural characterization and also acquired special skills in purification, conjugation, immobilization, chemical modification of biomolecules. I successfully designed and conducted various analytical experiments and organic synthesis processes for the biomolecular structural characterization.

• Outstanding 6+ years track record of successful experiences in developing and applying the state-of-the-art proteomics approaches to identify, quantify and characterize proteins and their modifications (glycosylations and phosphorylations) in the biological samples (with the use of Spectrum mill, Mascot and Discoverer software¡¦s).

• As a technical expert I regularly use specialized analytical techniques (Agilent Trap, Thermo Finnigan LTQ, Triple Quad, ABI/SCIEX 4000 QTRAP and Bruker MALDI TOF/TOF ultrafleXtreme with Eksigent 1D nano LC and Agilent LC systems) for proteins, glycans and lipids structural characterization, impurities ¡Vknown/unknown identification and trouble shooting the related technical issues.

• A strong background in chromatographic method development of various biological compounds. Provided support for new LC/MS system installation, preventative maintenance, troubleshooting and minor repairs of analytical scientific equipments.

• Established and achieved quantization methods (MRM and SRM modes) for small lipid molecules and metabolites using 4000 QTRAP mass spectrometer. Additional expertise in biological sample preparation (from tissues, cell lysates and tumors), protein purification, enrichment, fractionation techniques and protein enzymatic digestion.

• Provided bio-analytical support for drug discovery, biomarker analysis and identification of proteins during antibody pull-down assay with the help of SDS-PAGE Gel and western blot techniques.

• Independently determine experimental design, data evaluation, formulation of relevant and scientifically based conclusions, and coordinate/present studies with technical groups.
