CV - January 2019

Javier Ortega-Hernández  mexican_flag

Assistant Professor of Organismic and Evolutionary Biology
Curator of Invertebrate Paleontology in the
Museum of Comparative Zoology

 

Short Bio: I am an invertebrate paleobiologist interested in the evolution of major animal groups during the Paleozoic, with particular emphasis on the Cambrian Explosion and the Great Ordovician Biodiversification Event. Originally from Mexico City, I obtained my undergraduate degree in Biology from the Universidad Nacional Autónoma de México, and in 2008 completed the MSc in Palaeobiology at the University of Bristol in the United Kingdom. I then moved to the University of Cambridge from 2009 to 2018, first as a PhD student at the Department of Earth Sciences, and then as a Research Fellow of Emmanuel College and the Department of Zoology.

Research Associate

 

Short Bio: I am an invertebrate paleontologist investigating the evolution of early animals and their organization into modern-type ecosystems. To do so, I travel the world to study Konservat-Lagerstätten – exceptional deposits preserving the remains of both biomineralizing and soft-bodied organisms. These remarkable localities provide unparalleled insights into the anatomy and ecological interactions of extinct organisms. My preference goes to the Cambrian Lagerstätten of western Utah (Wheeler, Marjum, Weeks), but I am fortunate enough to work on Early Paleozoic exceptional fossils from all over the world. My areas of expertise are the biology, phylogeny and diversification dynamics of fossil and modern arthropods (and relatives), with special interests for gut anatomy and feeding strategies. I completed a Master (2001) and a Ph.D. (2004) in Paleobiology at the University of Montpellier, France – both on trilobite developmental strategies and mass extinctions – and then, occupied curator, research and teaching positions in Australia, France, and Germany.

Short Bio: My research program revolves around the evolution of complex characters considered ‘key innovations’ and their influence on phenotypic evolution and biodiversity through time. My toolkit draws on both the geological and genomic histories of organisms. Geological data are derived primarily from the ‘exceptionally preserved’ fossil record, i.e. those fossils that preserve soft tissues. Genomic data are used to reconstruct phylogenies of study groups, as well as to elucidate the distribution and expression of gene families across those groups. In combination, these data types provide reciprocal illumination of evolutionary innovations and set the stage for integrative studies of non-model organisms. I received my B.Sc. from the University of Toronto in 2007, and my Ph.D. from Yale University in 2012. I previously undertook postdoctoral positions at the American Museum of Natural History in New York City, and at the Massachusetts Institute of Technology

Richard J. Knecht  usa_flag

Graduate student

 

Short Bio: I am a paleobiologist and evolutionary ecologist that focuses primarily on terrestrial systems of the Paleozoic with a primary emphasis on early hexapods and the evolution of flight in insects (pterygota). I earned a BS in Geology from Tufts University where I worked on several research projects including the paleoecology of a Late Carboniferous intermontane basin, paleoecology and paleobiogeography of Pleistocene glaciolacustrine fossils using varve chronostratigraphy, and the paleobiology of a Carboniferous sponge forest before spending the next several years working in the collections of the Invertebrate and Vertebrate Paleontology Departments at the Museum of Comparative Zoology. I resumed my education and completed a MS in Geology from the University of New Hampshire, Durham. My research at UNH used resurrection ecology and the recovery of subfossil ephippia (resting eggs) of freshwater zooplankton to examine the structure, drivers, and limits of competition and coexistence in natural systems.

Sarah R. Losso  usa_flag

Graduate student

 

Short Bio: I am an invertebrate paleobiologist focused on trilobite phylogenetics, paleoecology, and macroevolution. I graduated from Mount Holyoke College in western Massachusetts in 2014 with a Bachelor of Arts in Biology, then completed an MS in Earth and Environmental Science from the University of Iowa. Research for my MS focused on description of five new species, assigned to a new genus of dimeropygid trilobites from the earliest stage of the Ordovician of western Utah and southeastern Idaho.

Museum of Comparative Zoology Intern - Summer 2019

 

Short Bio: I am currently a rising Junior earning a BS in geological sciences from Tufts University. Through Tufts I’ve studied fault geometry and rates in Death Valley National Park, as well as the paleoecology and geomorphology history of the Connecticut River Valley of the last two hundred thousand years. I’m interested in pursuing further studying of paleoecology, early evolution, and extinction events throughout history.
