Write-up of research and development interests/focus, past and present goals:


Protein Engineering and Evolution, Biocatalysis

R & D interests:

My group’s main area of research focus is engineering and evolution of pharmaceutically important proteins. Currently, proteins are in high demand by pharmaceutical industry as Biotherapeutics and Biocatalyst and are a multibillion dollar industry. However, Most of these proteins in development for use as biotherapeutic and biocatalyst have challenges like low expression in various cell lines, issues with protein misfolding difficult downstream processing, low stability, immunogenicity and others. My research work is to resolve the above issues by using protein engineering and evolution tools and successfully develop these molecules for use in biotherapeutics an biocatalysis.
