Javier Ortega-Hernández
Javier Ortega-Hernández is a Mexican invertebrate paleobiologist and evolutionary biologist.[1]. He is an Associate Professor of Organismic and Evolutionary Biology at Harvard University, the Curator of Invertebrate Paleontology at the Museum of Comparative Zoology, and an affiliated faculty member in Harvard’s Department of Earth and Planetary Sciences[2][3].
His research concerns the early evolution of animals, particularly Paleozoic invertebrates and the origin of major animal groups[2][3]. Much of his work focuses on exceptionally preserved Cambrian and Ordovician fossils, including early arthropods and their relatives[4].
Education and career
Ortega-Hernández is originally from Mexico City[1]. He studied biology at the Universidad Nacional Autónoma de México, where he received his undergraduate training before moving to the United Kingdom for graduate study[1][5]. In 2008, he completed an MSc in Palaeobiology at the University of Bristol[1][5]. He then moved to the University of Cambridge, where he began doctoral research in the Department of Earth Sciences in 2009[5]. After completing his PhD, he remained at Cambridge, where he was a Research Fellow at Emmanuel College and worked in the Department of Zoology[1][5].
In January 2019, he joined Harvard University as a faculty member in the Department of Organismic and Evolutionary Biology and as Curator of Invertebrate Paleontology at the Museum of Comparative Zoology[1][5]. At Harvard, Ortega-Hernández leads a research group focused on invertebrate paleobiology[2]. His work involves museum collections, fieldwork, fossil description, comparative anatomy, and the application of imaging techniques to exceptionally preserved fossils[3].
Research and contributions
Ortega-Hernández studies the early history of animal life during the Paleozoic Era, with particular emphasis on the Cambrian explosion and the diversification of invertebrate groups[1][2][3]. His published work covers the early evolution of panarthropoda, particularly fossils from Burgess Shale-type deposits[3].
At Harvard, Ortega-Hernández has focused on the Cambrian fossil record of the western United States, especially the Marjum Formation and related Burgess Shale-type deposits in Utah[6]. His lab has conducted fieldwork in the American Great Basin and studied a wide range of Cambrian organisms, including arthropods, sponges, pterobranchs, chordates, and other soft-bodied animals[6][7][8][9][10]
Public engagement
Ortega-Hernández has participated in public lectures and museum programming related to Cambrian fossils, early animal evolution, and the fossil record.[11][1]. In 2025–2026, he was listed as a Paleontological Society Distinguished Lecturer[1]
