My research goal is more focused on the translational research. My PhD and Postdoctoral training equipped me in the field of developing therapeutic humanized antibodies and its expression in mammalian cell system (CHO, HEK cells). To explore of my expertise, I involved in the development of therapeutic monoclonal antibodies and bispecific antibodies targeting CHI3L1 and immune-checkpoints (PD-1 or CTLA4). To understand the mechanism of therapeutic effect of developed antibodies in lung cancer.
My current research interest is contributed a new understanding on the bioactivity of CHI3L1. Using newly generated anti-phospho-specific Chi3l1 antibody targeting active motif of CHI3L1, I will able to identify, for the first time, that CHI3L1 is a highly phosphorylated glycoprotein and that phosphorylation status of CHI3L1 determines the bioactivity of CHI3L1. Thus, my expertise in antibody generation and characterization will be used to characterize the mechanism contributing to malignant phenotype changes of murine lung or cells in culture due to dysregulated expression of Chi3l1. In addition, the potential therapeutic efficacy of these antibodies will be effectively assessed with my prior experience in the development of therapeutic antibody.

Cellular signaling pathways for the efficacy evaluation of the plant expressed therapeutic antibody
Role: PI Role: ($67,000)
This grant studied about the efficacy of the plant expressed human antibodies may be affected due to the plant and mammalian various differences in endomembrane system, secretory pathway that are likely to cause changes in antibody glycosylation and other post-translational and secretary modifications. Therefore, understanding the differences between mammalian cell CHO expressed and plant expressed antibodies in interfering the cellular pathways in cancer cells are essential to predict efficacy of antibodies expressed by plants.

Molecular Characterization of mRNA transcripts tagged with H-ras in Bubalus bubalis genome.
Role: PI. ($15,000)
This grant studied about epetitive sequences are the major components of the eukaryotic genomes. The association of these repeats with transcribing sequences and their regulation in Bubalus bubalis has remained largely unresolved. This is significant because H-ras repeats owing to their shrinkage and expansion affect gene expression and are implicated in human diseases. In-depth analysis of H-ras gene is hoped to focus the search for elusive ones.
