Melissa Rivera is a graduate student in Electrical Engineering with a minor in Communications (Antenna Design) She worked for the Arecibo Observatory in Puerto Rico on research projects related with Astronomy and Antenna Design. One of this projects was focused analyzing data from the Jicamarca Radio Telescope in Peru using a radar system called JULIA. This study analyzed perturbations in the electric field as a result of geomagnetic substorms on equatorial latitudes. Another project was the design of 7.14GHz helix antenna for the Arecibo radio telescope platform. This antenna will help for Lunar Reconnaissance Orbiter data collection.
