Manuel Martínez Maldonado (born 1937) is a Puerto Rican internist and nephrologist, administrator, educator, poet and author who has authored scientific publications and edited several books. His research interests are the regulation of body fluids and the pathophysiology of blood pressure and its effects on the kidneys. He also focuses on the renin angiotensin system, a hormone system that helps regulate long-term blood pressure and blood volume in the body and which is controlled primarily by the kidneys. His clinical research has included polycycstic kidney disease, renal stones and hypercalcemia. Martinez-Maldonado has occupied numerous positions, including Vice President for Research at Oregon Health and Sciences University (1998-2000), President and Dean of the Ponce School of Medicine (2000–2006). He was the executive vice president for research at the University of Louisville from 2000 to 2009.^[1]

Martínez Maldonado, born in the southern town of Yauco, Puerto Rico, was an only child. He received his primary education in Holy Rosary School in Yauco, St Joseph School in San Germán and Holy Spirit School in Hato Rey. His secondary education took place in the Matienzo Cintron School in Santurce and the JJ Osuna School in Hato Rey. He attended the University High School and was the president of the graduating class in 1954. After graduating from high school, he entered the University of Puerto Rico, where he studied chemistry and literature. In his sophomore year, Martínez Maldonado decided that he would like to study medicine instead of literature. He graduated magna cum laude and was accepted at Temple University School of Medicine (TUSM), in Philadelphia, Pennsylvania, where he earned his medical degree. After residency in internal medicine at the San Juan Veterans Administration Medical Center and University Hospital, he completed his postdoctoral study on renal and electrolyte metabolism at the University of Texas Southwestern Medical Center.^[2]

Martínez Maldonado became interested in the field of renal physiology and, later on, in nephrology, and was accepted by the Dallas Southwestern Nephrology Division, where he became an investigator and carried out many of his initial experiments.^[3] He became an independent investigator at Baylor College of Medicine in Houston where he rose from an assistant to a full professor of medicine with tenure (1968–1973). Nephrology is a branch of internal medicine and pediatrics dealing with the study of the function and diseases of the kidney.^[4]

Martínez Maldonado perfected a technique that could measure the osmolality of samples (nanoliters) of proximal tubar fluids.^[3] He and his colleagues at Baylor designed a clinical treatment for hypercalcemia that was in use until the beginning of this century when specific medications were developed for the condition.^[3]

In 1973, Martínez Maldonado ended his professorship at Baylor University to become Associate Chief of Staff for Research at the San Juan Veterans Administration Medical Center, and professor and Chair of the Department of Physiology, and Professor of Medicine at the University of Puerto Rico School of Medicine. During his time at Baylor College of Medicine he published 39 original investigations in various journals such as the Journal of Clinical Investigation, the New England Journal of Medicine and the American Journal of Physiology..^[3] This scholarly activity continued in his Renal Metabolic Laboratory at the San Juan VA and the department of Physiology. He rescued the department of physiology by recruiting new faculty staff and sending students to train in important physiology departments in the United States and recruiting them back to the island. He is credited for the development of an outstanding training program for internal medicine at the San Juan VA and responsible for the identification of talent among his students. Many of those occupy important positions in academic medicine and clinical practice in Puerto Rico and the United States.

Martínez Maldonado, who is married with four children, published five books of poetry and two novels.^[3][5]

In addition he was editor or co-editor of several books such as:

• Methods in Pharmacology, vol. IVA, Renal Pharmacology. New York: Plenum Publishing, 1976.
