Short Biography

Dr. Kenneth R. Morris received a dual B.S. in Chemistry and Aquatic Biology from Eastern Michigan University in 1978 an M.S. in Pharmaceutical Chemistry from the University of Arizona (1986) and his Ph.D. from the University of Arizona in 1988. After getting his Ph.D., he joined E.R. Squibb and Sons. There he developed the Physical Characterization group and co-developed the Materials Science function. He went on to form the Pre-formulation/Physical Pharmacy group in the Bristol-Myers Products organization, which he led along with Analytical Chemistry. During his time at BMS he also served as a teaching and advising adjunct professor at Rutgers College of Pharmacy and St. Johns University. Dr. Morris then moved to the department of Industrial and Physical Pharmacy at Purdue University in the fall of 1997 where he continued his work in Pharmaceutical Materials Science and Industrial Pharmacy. He was also a professor and associate head for the department. In 2008 Dr. Morris moved to the University of Hawaii at Hilo to help establish the new College of Pharmacy and Ph.D. program in Pharmaceutical Sciences. He also served as the Department Chair from 2012-2015 and Chair of the Graduate Council for the University. In 2015 Dr. Morris moved to Long Island University as a University Professor and founding Director of the Lachman Institute for Pharmaceutical Analysis. His research and teaching interests include: analytical tools for solid state characterization; the study of the impact of processing on the physical characteristics of formulation components and on subsequent dosage form performance; pharmaceutical unit operation optimization; advanced applications of powder x-ray diffraction and dielectric analysis; the study of the association of water with pharmaceutical solids; and modeling and methods for monitoring processing unit operations. Dr. Morris is an AAPS fellow (American Association of Pharmaceutical Scientists) and was the Purdue University Site leader for the NSF Engineering Research Center for Structured Organic Composites (ERC-SOPS). Professor Morris is a special government employee and past-chair of the U.S. FDA Scientific Advisory Committee for the Office of Pharmaceutical Sciences (ACPS-OPS) advising the agency in his areas of expertise.


Research Synopsis

The majority of my research is in the emerging discipline of Pharmaceutical Material Science. This area can be described as the study of the impact of the physico-chemical properties of formulation components on the performance of the final pharmaceutical dosage form. These properties include: particle size, shape, surface area, and charge; crystal structure, lattice energy, forms (i.e.: polymorphs and hydrates), morphology; relative crystallinity (and amorphous content); hygroscopicity; and solubility. These properties affect powder flow, mixing, compaction, and physical stability, which, in turn, determine the dosage form performance. Changes in these critical properties that occur during processing can, therefore, alter dosage form performance. A focus of our research is the use of advanced analytical techniques to follow these properties throughout the manufacturing process. The techniques include: powder and single crystal x-ray diffraction, differential scanning calorimetry, thermal gravimetric analysis, mid and near diffuse reflectance Fourier transform infra-red spectrophotometry, dielectric spectroscopy, and molecular and crystallographic modeling.
