Key Highlights

 

 

 

My group is primarily interested in developing translatable technologies and products using synthetic biology approaches. We utilize latest genome editing technologies and DNA assembly methods to engineer microorganisms and human cells.

Research Projects:

  1. Developing tuneable yeast gene expression system using synthetic promoters and gene editing technology
    Distinct biotechnological applications require different promoter properties in terms of expression range and inducibility. Currently promoter discovery is largely focused on manipulating native promoters which are large DNA sequences and are regulated in a complex fashion. We are generating a library of yeast cells containing distinct promoter activities for production of high value biomolecules over a broad dynamic range in a high throughput format. To achieve this, the group is focusing on engineering novel synthetic promoters that are tuneable, programmable and orthogonal in nature. In addition, we are developing a repository of synthetic genetic parts and elements that together with the promoters will create a suite of expression cassettes for customized and enhanced expression of biomolecules.
  2. Metabolic engineering of yeast cells for biotechnological applications
    Yeast is recognized as GRAS organism and used extensively for industrial production of valuable molecules. In this project, we are generating value-added yeast strains that overexpress phytochemicals, food supplements, human metabolic enzymes and nutraceuticals. This will be achieved by rational engineering of the endogenous metabolic genes in yeast cells or transplanting genes from heterologous sources by using recombinant DNA methods. Using gene editing technologies, we also seek to modify metabolic pathways in yeast cells to generate “humanised yeast stains” for production of human therapeutic proteins and biologics.
  3. Engineering human cells for therapeutic applications
    We are establishing a robust protocol and platform for precise bespoke gene editing of human cells for various therapeutic purposes. The group will be generating human cell lines that (a) mirror disease-causing mutations for drug resistance studies and screening purposes, (b) develop gene editing strategies for gene correction and functional genomics studies, and (c) improve existing therapeutic approaches to autoimmune diseases, cancers and rare genetic disorders.
  4. Functional genomic approaches to combat vector-borne diseases
    Recently viruses belonging to the family Flaviviridae have become a major public health problem worldwide including India. Using the Aedes-Dengue virus infection model, we aim to identify and characterize key factors controlling virus multiplication in the mosquito using genome wide approaches. Subsequently we will be translating this knowledge to design effective disease transmission blocking strategies for Dengue and other viral infections.
