Mark Q. Martindale is an American evolutionary developmental biologist and professor at the University of Florida. He was director of the University of Florida's Whitney Laboratory for Marine Bioscience from December 2012 to December 2024. He previously held faculty positions at the University of Chicago and the University of Hawaiʻi at Mānoa, where he served as director of the Kewalo Marine Laboratory.

He was elected a Fellow of the American Association for the Advancement of Science in 2008 and received the Alexander Kowalevsky Medal for Comparative Embryology in 2009. His research focuses on animal development and evolution, particularly in marine invertebrates such as spiralians, ctenophores, and cnidarians.

Early life and education

Martindale was born in Cleveland, Ohio. He received a B.A. in natural sciences from New College of Florida, then known as New College of the University of South Florida, in 1981 and a Ph.D. in zoology from the University of Texas at Austin in 1985.

Following his doctorate, Martindale held appointments in the Department of Zoology at the University of Texas and in the Department of Anatomy and Cellular Biology at Harvard Medical School.

Academic career

Martindale joined the faculty of the University of Chicago's Pritzker School of Medicine in 1990, where he became an associate professor. He later joined the University of Hawaiʻi at Mānoa, becoming a professor at the Pacific Biomedical Research Center's Kewalo Marine Laboratory and serving as its director from 2007 to 2012.

In 2012, Martindale joined the University of Florida as professor of biology at the Whitney Laboratory for Marine Bioscience and became its director in December of that year. He held the directorship until December 2024 and continues as a professor at the university.

Research

Martindale was involved in a 2008 study published in Nature that used broad phylogenomic sampling to examine evolutionary relationships among animal groups. The study reported molecular support for placing ctenophores as the earliest-diverging extant animal lineage, although the evolutionary position of ctenophores has remained a subject of research and debate.

In 2013, Martindale coauthored a paper published in Science reporting the genome sequence of the ctenophore Mnemiopsis leidyi. The study examined the genome in relation to animal cell type evolution and developmental systems and contributed to debate concerning the phylogenetic position of ctenophores.

Martindale's work has examined developmental mechanisms in Mnemiopsis leidyi, including the relationship between wound healing, cell proliferation, and regeneration. A 2022 study coauthored by Martindale reported that Mnemiopsis leidyi begins reproductive activity at an earlier developmental stage than previously recognized. The findings challenged the interpretation of its early life stage as a distinct larval phase and contributed to research on life-history evolution in ctenophores.

Research involving Nematostella has examined evidence of bilateral organization in cnidarians and the evolutionary conservation of developmental genes. These studies have contributed to understanding the relationship between genomic complexity and animal body-plan evolution. Martindale has also investigated cnidarian–dinoflagellate photosymbiosis, including the potential use of the upside-down jellyfish Cassiopea as an experimental model.
