The primary mission of the Industrial Pharmacy Program at St. John’s University is to educate and train students to address drug product development needs of pharmaceutical companies in the USA, the majority of which are located in the northeast region of the USA within 200 miles of the university. It is one of the only two such Industrial Pharmacy programs in the USA. To meet the industry needs and develop better drug products, Prof. Abu Serajuddin has built the Industrial Pharmacy Innovation Center at St. John’s University and is currently conducting research in the Center in following areas: 

  • Development of novel drug delivery systems (especially for poorly water-soluble drugs) 
  • Development advanced processing and continuous manufacturing technologies for solid dosage forms
  • 3D printing technology for personalized medications
  • Development of abuse-deterrent drug products
  • Cell culture study for evaluation of formulation safety and drug permeation

Download Industrial Pharmacy Innovation Laboratory, Facilities and Equipment, for a list of research equipment

  • In addition to Dr. Serajuddin, there are 7 professors in the Industrial Pharmacy program at St. John’s University, each having own laboratory. All eight of them share lab facilities and resources with each other, as needed.
  • The Industrial Pharmacy program is a part of the Department of Pharmaceutical Sciences, which, in addition to Industrial Pharmacy, consists of Medicinal Chemistry, Pharmacology, Toxicology and Biotechnology having 41 members in the faculty. All of these disciplines have PhD programs, except for biotechnology (MS only), and thus Prof. Serajuddin can conduct advanced and collaborative research in all areas of pharmaceutical sciences. He can also freely use any equipment and facilities in other laboratories, when needed.
  • St. John’s University is currently building an Innovation and Incubation Center for collaborative research with different industries and business ventures, including pharmaceutical and biotech industries, to bring ideas and inventions coming out of the university into marketable stage. A central 1,000-sq. ft. office facility for the Center has already been built where internal and external partners as well as other stakeholders can meet and work together. Different existing laboratories in the university are now used for research. There are plans to build new laboratories where industry partners can conduct their own research to develop products. Prof. Serajuddin is a member of the Center, and he will utilize its resources, as needed, to foster collaboration with other colleges in the university as well as with the pharmaceutical industry.
