S. Kamal Jonnalagadda PhD

Associate Professor of Pharmaceutics


BPharm (Birla-India)

PhD (Nebraska)

Research Interests

The research focus in our laboratory is the design, characterization, and the modeling of polymeric biomaterials for specific pharmaceutical applications. Applications include: (1) solid dosage forms: polymorphic transitions as a function of excipient concentration, storage (or ageing), and during the different stages of drug formulation, such as mixing, granulation, drying and compression. (2) biodegradable polymeric implants for macromolecular drug delivery and tissue engineering.


Dr. Jonnalagadda earned a Ph.D. from the University of Nebraska and a B.Pharm. from BIT, in India. He studies the design, characterization and modeling of polymeric biomaterials for specific pharmaceutical applications, including solid dosage forms and biodegradable polymeric implants for macromolecular drug delivery and tissue engineering.
