Research Focus

drug delivery; bio-electrostatics; transport phenomena in biological systems; biomechanics; osteoarthritis


Prof. Bajpayee works on drug delivery to connective and charged tissues such as cartilage, meniscus, intervertebral disc and mucosal membranes. Her lab utilizes concepts of nanomedicine and bio-electrostatics to design polypeptides and protein-based carriers for targeted and sustained delivery of small molecule drugs, protein growth factors, antibodies and genetic materials to specific intra-tissue and intra-cellular target sites inside connective tissues. A main focus is on using charge interactions and other binding mechanisms to rationally design drug carriers that can penetrate through the dense matrix of avascular, negatively charged tissues. Her lab is also interested in understanding mechanisms leading to degenerative joint diseases (e.g., osteoarthritis) due to ageing and traumatic injuries. The group strives to combine basic science with translational research to develop biomedical technologies.
