Edgard Rivera-Valentin is currently a Staff Planetary Scientist in the Department of Solar System Studies at the Arecibo Observatory in Arecibo, PR. Ed is the first Arecibeño to serve as a scientist at the observatory and among the counted few Puerto Ricans. His research interests focus on two aspects of astronomy: “How did we get here?” and “Are we alone?”. In his research, Ed uses numerical techniques along with observations to understand early solar system processes by way of impact craters. He additionally studies volatile stability and transport on planetary surfaces in search for habitable abodes beyond Earth.
Ed received a Bachelor’s degree in 2008 from Alfred University where he double majored in Physics and Mathematics and minored in Planetary Science, a minor which he helped establish at Alfred. After an internship at the Lunar and Planetary Institute in the summer of 2007, Ed was convinced that planetary science was what he wanted to study. He went on to earn his doctoral degree in Space and Planetary Sciences at the University of Arkansas in 2012. After 2 years as a Postdoctoral Research Associate at Brown University with Dr. Amy Barr, Ed joined the staff at the Arecibo Observatory. Ed now leverages his position at the observatory to be an advocate for under represented minorities in STEM and is actively involved in education and public engagement activities at the observatory.
Ed can normally be found on Twitter at @PlanetTreky. He also co-tweets through @AreciboRadar, the official twitter account of the Planetary Radar Group at the Arecibo Observatory, and through @NAICobservatory, the official account for the Arecibo Observatory.
