Siri is a team lead for systems engineering and program administration of lunar rovers at Carnegie Mellon University. She started at CMU as a mechanical engineer and soon became the program manager for the multiple NASA contracts that created the Iris program. This rover was later named in her honor after she graduated. (“Iris” is “Siri” backward.) Before returning to the now-Iris program as its Administrative Manager, Siri led nuclear robotics developments at Carnegie Mellon, culminating in the first robotic assayer of enriched uranium officially commissioned by the U.S. Department of Energy. She also served as a mechanical engineer for the U.S. Air Force Research Laboratory and then the Naval Nuclear Laboratory, as well as a staff researcher for the Pennsylvania State University.
