Ana María Rule

Ana María Rule is an Assistant Professor of Environmental Health and Engineering with the Johns Hopkins School of Public Health and director of the University’s Environmental Exposure Assessment Lab. She earned her B.Sc. in Biomedical Engineering from the Universidad Iberoamericana, followed by an MHS in Industrial Hygiene and a PhD in Environmental Health Sciences from Johns Hopkins University.

Dr. Rule has been awarded many honors, including a Fulbright Scholarship, the David L. Swifit award in Environmental Health Engineering, Reconocimiento a la Superación Académica – FICSAC (Recognition of Academic Achievement, granted by the Commission for Academic Promotion of the Universidad Iberoamericana, Mexico), and awards for teaching excellence from the Johns Hopkins Bloomberg School of Public Health.  The latter is unsurprising, as Dr. Rule is committed to education. In addition to teaching activities and advising over 20 graduate students to date, she has also recently been engaged in outreach efforts to explain mask use and hierarchy of control concepts during the ongoing COVID19 pandemic – in English and in Spanish!

Dr. Rule has over 20 years of experience in the investigation of airborne contaminants and related health effects, with a current research focus on the development and evaluation of novel sampling and analysis strategies for the assessment of exposure to biological aerosols, e-cigarette aerosols, and particulate matter.  Some highlights from her recent work include establishing e-cigarettes as important sources of metal exposures and providing insights into bacterial aerosol viability and the application of analysis techniques traditionally used for water samples. She is also involved in the study of biological aerosol particles in close collaboration with microbiologists and aerosol physicists to advance the development of strategies for improved sampling and detailed laboratory characterization.

Dr. Rule has been an active member of the International Society of Exposure Science since 1999 and currently Co-Chairs our Diversity Committee, serves on the Nominations Committee, and continues to volunteer with annual meeting Technical Organizing Committees.  She has also been elected to the Society Board at various stages of her career, serving as both Academic Councilor and Student Councilor.  Dr. Rule is also an active member of several other professional societies, including the American Industrial Hygiene Association, the American Association for Aerosol Research, and the American Society of Agricultural and Biological Engineers.  Dr. Rule was also active with the Mexican Society of Biomedical Engineers (SOMIB) for over two decades, serving on the SOMIB Board for several years.
