Mohd Abul Kalam earned his PhD (Pharmaceutics) in 2011 from the Faculty of Pharmacy, Jamia Hamdard, New Delhi, India. He is presently working as Associate Professor (Pharmaceutics) at the College of Pharmacy, King Saud University, Riyadh, Saudi Arabia. His main focus of research encompasses the development and evaluation of ocular drug delivery systems. Nanoformulations and their physicochemical characterization using solid lipids and polymer systems are major interests. Currently he is utilizing poly (D, L-lactic-co-glycolic acid) to prepare and optimize nanoparticles for the ophthalmic use. Novel drug delivery systems such as solid lipid nanoparticles, in-situ sol-gel and surface-modified nanocarriers are his research area.
