Areas of Expertise

Biopharmaceutics, formulation development of oral modified release systems and solid dispersions, thermal and mechanical analysis of small and large molecules including proteins and polymers.

Research mission statement

My research works towards bridging the physical and biological sciences in the field of pharmaceutics. For the effective design of oral, modified release dosage forms which behave in a reproducible manner, we need to have a clear understanding of the in vivo conditions to which they will be subjected. My current research collaborations with medical schools are enabling me to understand drug behavior in healthy individuals as well as patients. I am working on the fundamental characterization of the gastrointestinal mucosa and luminal environment and utilizing this knowledge in several different ways. First, to set up an in vitro drug release model which better simulates the dynamic and diverse nature of the gastrointestinal tract. Second, to design oral, modified release systems that have a more predictable performance in man and therefore display reduced interindividual variability.
