Bedell joined the faculty at Johns Hopkins University in 1930 as a house officer in their department of medicine. The following year, she was promoted to assistant professor of medicine at Johns Hopkins School of Medicine where she led studies in electrocardiography. Bedell returned to Johns Hopkins School of Medicine as a faculty member following her Harvard fellowship in 1935. She also became a married woman to Dr. Henry M. Thomas, Jr, taking his last name. While working under mentor and department chair
Warfield Theobald Longcope, she studied neurogenic models of hypertension and the effects sympathectomy has on blood pressure. Thomas simultaneously served as a physician at the
Bryn Mawr School, a civilian consultant to the Army Surgeon General, and operated a private practice. The results of her research found that of the males studied, those who developed
coronary artery disease also had high cholesterol but not vice versa. She also found that graduates who suffered anxiety or depression as students were more likely to be fatigued and achieve lower academic standings. Thomas believed that physical diseases had genetic, environmental, psychological, and physiological components to them. Prior to her retirement, Thomas published over 130 Precursors Study manuscripts in peer-reviewed journals. Although the study became influential, Thomas had a difficult time maintaining its funds. She would often take less salary money or end the cohort enrollment early. Due to lack of funds, 1964 was the last cohort Thomas studied. She became desperate enough for funds that she would offer family heirlooms to donors in exchange for donations, although no one ever accepted. Prior to ending the study, she received the 1957 James D. Bruce Memorial Award for her work in preventive medicine. In June 1970, Thomas was promoted to the rank of Full Professor, the third female to do so. She maintained this role until her retirement in 1986 at the age of 82. Thomas died on December 14, 1997, due to illness at Roland Park Place in Baltimore. ==References==
