Having earned a National Science Foundation Scholarship and an honorary Woodrow Wilson Fellowship, she then pursued graduate work at the University of California. In 1967, Rajnak returned to Kalamazoo College to teach in the Physics Department, the first woman to teach in this department. She published numerous articles throughout her career and also worked on projects at the Argonne National Laboratory and the Lawrence Livermore Laboratory.
