SUMMARY

Ph.D. in Antibody Engineering/Biotechnology, developed 13 new diagnostic and therapeutic peptide monoclonal antibodies (mAbs) from Prof. Dr. Glenn Morris’s lab. Epitope mapping of one of the mAb was done by Phage displayed peptide library. The lab produced over 450 mAbs at that time available online for commercial research purposes. Developed expertise in Fmoc peptide synthesis, purification, immunization, hybridoma screening, and determination reactivity against native and denatured proteins.

Over five years of experience from Prof. Dr. Thilo Stehle’s Biotechnology lab at Harvard University. Worked on Antiviral Drug Discovery program as a Research Fellow. Performed gene cloning, protein expression by cell, Yeast and bacterial culture techniques to produce highest quality protein for purification and crystallization using multiple strategies, including final purification by Bio-Rad laboratory FPLC system. Out of two, one protein was crystallized. Note: Prof. Stehle moved to Germany due to personal reasons.

During five years of service as a Research Scientist at Albert Eistein College of Medicine at Yeshiva University, applying Tissue Microarray (TMA) Engineering technology, developed TMA at Prof. Dr. John Mariadason’s laboratory. Forty-six patient’s biopsy sections were collected with collaboration a team of physicians and surgeons and analyzed hundreds of up and downregulated proteins causing colorectal cancer. Note: Prof. Mariadason moved to Australia due to personal reasons.

Scientist (strong scientific skills in basic medical sciences and clinical research is evident from the fact that over thirty articles were published in the Journal of Biological Sciences) with excellent communication, teaching, and training skills (earned best teacher award from seral organizations) willing to work independently and with a team.
