Marla Lujan received her Master of Science and Doctor of Philosophy in Physiology from Queen's University (Kingston, Ontario). She conducted her postdoctoral studies in Obstetrics, Gynecology and Reproductive Sciences at the University of Saskatchewan prior to joining the Division of Nutritional Sciences at Cornell. The focus of her research relates to the interplay of nutrition and metabolic status with women’s reproductive health. Specific interests include understanding mechanisms whereby diet, glucoregulatory status and adiposity impact ovulation and lead to loss of regular menstrual cycles (amenorrhea) in women. Her group uses high-resolution ovarian ultrasonography to characterize follicle development during natural cycles, with the goal of corroborating the utility of ovarian morphology to inform distinct causes of anovulation - such as polycystic ovary syndrome (PCOS), ovulatory responses to diet intervention, degree of cardiometabolic disturbance and risk of PCOS in adolescents. Her work also includes cross-disciplinary assessments aimed at understanding unique challenges faced by women with endocrine disruptions including usual dietary intake and physical activity, health-related knowledge and beliefs as well as experiences with healthcare providers.

I strive to deliver an introductory Human Anatomy and Physiology course that effectively provides all students with a working knowledge of the major organ systems through experiential learning. I am dedicated to developing and administering evaluation tools that fairly assess students while challenging them to think more broadly about the application of knowledge learned in class. Last, I work to foster a classroom environment in which students trust and value their learning experience. As an advisor, I assist trainees in developing an educational program that is consistent with their career and personal goals. I work with trainees to secure accurate and timely information about programmatic requirements and to foster an environment in which trainees feel secure to discuss their interests, aptitudes and limitations.
