Joshua Porter is currently a National Science Foundation Graduate Research Fellow and graduate student of Dr. Amelia Villaseñor in the Department of Anthropology at the University of Arkansas in Fayetteville, AR. Since 2018, Joshua has assisted Dr. Richard Potts of the Human Origins Program in spatial analyses of early Pleistocene sites in the southern Kenya rift. He holds a BS in Biological Anthropology from the George Washington University. Since 2020, he has been an affiliated researcher with the Stone Age Archaeology lab at GWU. Joshua’s research uses the fossil record and stable isotope ecology to identify the cascading ecological changes associated with megafaunal extinctions and anthropogenic ecosystem engineering through time and across space. In addition, he is interested in identifying functional and practical limitations of paleoecological proxies, particularly those associated with dental wear and stable isotopes from tooth enamel.
