Research Interests

  • Cancer Biology Developing small molecules/peptides targeting novel oncogenes, establishing the molecular mechanism of action of new drugs - using CRISPR/Cas9 screens, studying mechanisms of therapy resistance, and developing pre-clinical models of tumor progression including xenografts (patient derived explant [PDeX] and patient derived Xenograft [PDX]) models.

  • Expertise in generating Monoclonal and Polyclonal antibodies for diagnostic applications
