Raphael (Ray) P. D'Alonzo is retired from the Procter & Gamble Company (P&G) and a former University of Massachusetts Amherst visiting and adjunct professor and former University of Cincinnati Evening College instructor.

Dr. D'Alonzo obtained a B.Sc. in chemistry with honors in 1974 from the Philadelphia College of Pharmacy & Science (acquired by St. Joseph's University in 2022) and his Ph.D. in analytical chemistry in 1977 from the University of Massachusetts Amherst where he studied and developed a variety of atomic absorption and emission spectroscopic methods for quantifying trace organic compounds in food, pharmaceutical and environmental samples under Prof. Sidney Siggia.

After receiving his Ph.D., he joined P&G's Foods Division where he applied a variety of chromatographic and spectroscopic techniques for the determination of trace organics in food products and packaging materials. In 1982, he was appointed Director of Analytical Chemistry in P&G's Bar Soap & Household Cleaning Products Division and in 1983 was elected Chair of P&G's Worldwide Analytical Coordinating Committee, a body composed of 23 analytical organization leaders from around the world managing more than 200 Ph.D. analytical chemists. In 1984, he was transferred to P&G Pharmaceuticals where he managed the research program that discovered risedronate which successfully progressed to become Actonel®, a 1.7 billion dollar osteoporosis drug. He was appointed Senior Director in 1986 where he managed a variety of clinical research and operational departments for the next 22 years. Under his leadership, P&G Pharmaceuticals received patents for novel potent and broad-spectrum anti-infective compounds, regulatory approval for the first non-steroidal osteoporosis drug in the world (etidronate in France) and became the first pharmaceutical company in the world to implement a system for harvesting and validating clinical data using the Internet as documented in Harvard Business School case study #9-606-033. In 2006, he was appointed Senior Manager in P&G's R&D Administration organization with responsibility for worldwide university technical relations until he retired in 2008.

Dr. D'Alonzo has been active in several professional organizations including the American Chemical Society (ACS), the Society for Applied Spectroscopy, the American Society for Bone and Mineral Research, and the Chiari & Syringomyelia Patient Education Foundation. He has served as Chair of the ACS Cincinnati Section composed of 1,600 members and as President of the Cincinnati Section of the Society for Applied Spectroscopy.

Dr. D'Alonzo's publications are diverse ranging from various topics in analytical chemistry to pharmacoeconomics. He has been invited to speak on various topics of analytical chemistry and drug research and development at over a dozen colleges and universities.

In 1995, Dr. D'Alonzo was honored as the recipient of the University of Massachusetts Distinguished Alumni Award and later in 2000 with the University's highest award, the Chancellor's Medal.

Since retirement, Dr. D'Alonzo has become the owner of several successful small startup businesses and has served on the board of directors of the Northern Cincinnati Community Foundation and the Joint Economic Development District I of Liberty Township, Ohio.
