Research Interest/Area

Diabetes, Chronic wound healing, biopolymers, Nanoparticles, PRP


Wound healing is a complex physiological process with 4 stages of healing. The stages of healing are delayed in diabetic conditions due to various factors thus hampering the wound closure. These wounds when not treated often lead to amputations imparting and huge financial burden on the patients.

My work interest lies in developing a formulation composed of nanoparticles for the delivery of various growth factors to the wound site to target the delayed healing in diabetic foot ulcers.
