of Science degree in electrical engineering from Carnegie Mellon University (as it now was) in 1970. She became a member of Tau Beta Pi and Eta Kappa Nu honor societies. Resnik married Oldak on July 14, 1970. Her mother attended the wedding; two sets of invitations were sent out, one describing her as her father's daughter, and the other as her mother's. Upon graduation from Carnegie Mellon, Resnik and Oldak moved to Moorestown, New Jersey, where they both worked for RCA. She was a design engineer on missile and radar projects and won the Graduate Study Program Award. She performed circuit design for the missile and surface radar division. While at RCA, she worked for the Navy building custom integrated circuitry for the phased-array radar control systems and developed electronics and software for NASA's sounding rocket and telemetry systems programs. An academic paper she wrote on special purpose integrated circuitry caught the attention of NASA during this time. She registered for master's degree evening courses at the University of Pennsylvania. In 1971, Oldak was accepted into Georgetown University Law Center, and they moved to Washington, D.C. Resnik continued to work for RCA, transferring to its office in Springfield, Virginia, and she continued pursuing her master's degree at the University of Maryland. She then entered a doctoral program. Resnik and Oldak divorced in 1975—he wanted children and she did not—but they remained in contact and on good terms. While working on her doctorate, Resnik switched jobs in 1974, and went to work as a research fellow in biomedical engineering at the Laboratory of Neurophysiology at the National Institutes of Health. As a biomedical engineer, Resnik researched the physiology of visual systems. In 1977 she earned her PhD in electrical engineering with honors at the University of Maryland, writing her dissertation on "Bleaching kinetics of visual pigments". Her research involved the effects of electrical currents on the retina. An academic paper co-written by her concerning the biomedical engineering of optometry ("A novel rapid scanning microspectrophotometer and its use in measuring rhodopsin photoproduct pathways and kinetics in frog retinas") was published in the Journal of the Optical Society of America in 1978. NASA astronaut Selection and training After her divorce from Oldak, Resnik reconnected with Nahmi, who was now a commercial airline pilot. When he heard that the National Air and Space Administration (NASA) was recruiting women to become astronauts, he encouraged her
