Dr. Hawes began her education by pursuing a certificate in vocational nursing from Santa Ana College followed by a BA degree in French from Cal State Fullerton. She then attended medical school, and upon graduation she was first introduced to the Keck School of Medicine as a resident in the pathology department at LAC+USC Medical Center. While in medical school, Dr. Hawes demonstrated a profound aptitude for her studies when she was awarded to the Dean’s List of Outstanding Achievement in the Basic Sciences. Currently, Dr. Hawes is an assistant professor of clinical pathology and an instructor of the Pathology Multidisciplinary Laboratories at USC. She has reviewed manuscripts for the several medical journals, including the prestigious New England Journal of Medicine. In addition to her vast academic and clinical responsibilities, Dr. Hawes has a number of research interests, such as cancer prevention, new technology development and biologic markers of disease progression. Dr. Hawes has co-authored nearly 30 peer-reviewed journal articles and a number of book chapters and abstracts.
