Research Interests

Development and validation of liquid chromatography-mass spectrometry (LC-MS/MS)-based assays/methods have been a part of research activities within the Clinical Chemistry Laboratory. Outcomes of such activities, some were done in collaboration with colleagues at CDC and University at Albany, SUNY, led to 8 articles published in peer-reviewed scientific journals during 2017-early 2019 alone in the areas mainly including (1) analytical accuracy and precision assessment of IVD and assays for patient testing, (2) clinical laboratory quality performance evaluation via accuracy-based proficiency testing or external quality assessment, (3) identification of quality issues in analytical & post-analytical phases, (4) salivary hormone tests using LC-MS/MS methods and (5) their application in psychological research, where noninvasive detection of hormones is needed. My past research experience and interests included protein purification and characterization, gene mutation identification, production of mutant proteins via site-directed mutagenesis, and analysis of the impact of a gene mutation on the protein expression levels, structure, stability and functional properties.
