Mr. Gottlieb is the Executive Director of the Public Health Advocacy Institute at Northeastern University School of Law in Boston. The Institute's nine attorneys conduct legal research and policy analysis around the intersection of law and public health. For the past 20 years, he has focused his research on legal approaches to reduce the harm caused by tobacco industry products. Mr. Gottlieb consults with the AAP Richmond Center on the law and policy implications of the Center's research projects within the field of tobacco control.

Dr. McGrath-Morrow is a pediatric pulmonologist and clinician scientist who runs a translational laboratory modeling neonatal lung injury. Her research interests include understanding the neonatal immune response to acute lung injury, respiratory outcomes in preterm infants with chronic lung disease and the impact of secondhand and thirdhand smoke on postnatal lung growth and adult lung function. Her work is funded by National Institutes of Health and the American Academy of Pediatrics Julius B. Richmond Center. She is also the Johns Hopkins Pediatric Pulmonary Fellowship Director.

Robert McMillen, PhD
Robert McMillen Dr. McMillen is the PI of the Data and Datasets for the AAP Richmond Center. Dr. McMillen's research applies computer-assisted telephone interview methods as well as Web- and school-based survey methods to measure the social climate surrounding health issues. The annual Social Climate Survey is one product of this research, and is an ongoing collaboration between the Mississippi State Social Science Research Center and the AAP Richmond Center. In recognition of his research contributions, he was awarded the 2006 Prevention of Cancer in Mississippi Award by the Mississippi Partnership of Comprehensive Cancer Control. His research has been supported by the Centers for Disease Control, the Mississippi State Department of Health, The Partnership for a Healthy Mississippi, the American Cancer Society, and the Mississippi Health Advocacy Program. Dr. McMillen is an Associate Professor with a joint appointment with the Social Science Research Center and the Department of Psychology at Mississippi State University.

Ana Rule, PhD
Ana Rule Dr. Rule is a research scientist and faculty member at the Department of Environmental Health Sciences at the Johns Hopkins Bloomberg School of Public Health, where she directs the Secondhand Smoke Exposure Assessment Laboratory. Throughout her research career she has focused on methods and measurements for assessing human exposure to contaminants in the community and work environments as a basis for developing strategies for prevention. Dr. Rule has been involved in several studies linking human exposure to nicotine, PAHs, metals, bioaerosols, and ambient air pollution through multiple environmental media. These large-scale projects complement laboratory-based studies where controlled experiments are used to better investigate and refine sampling methods. Dr. Rule’s current research includes community-based exposure assessment, the role of exposure to metals, exposure and effects from mobile source related air pollution, methods for measuring bioaerosols, and the development and evaluation of air sampling equipment. Dr. Rule is a Co-PI on the AAP Richmond Center Measurement Core project.

Susanne Tanski, MD, MPH, FAAP
Susanne Tanski Dr. Tanski is the PI of the Messaging project for the AAP Richmond Center. Dr. Tanski is an Associate Professor of Pediatrics at Geisel School of Medicine at Dartmouth and a practicing pediatrician at the Children's Hospital at Dartmouth of Dartmouth-Hitchcock Medical Center. Working within the Cancer Risk Behaviors Group at the Norris Cotton Cancer Center at Dartmouth, her current research endeavors focus on visual media influences on adolescent smoking and drinking, and communication between pediatric clinicians and parents regarding SHS exposure of children. Dr. Tanski currently chairs the AAP Tobacco Consortium, a national group of researchers who take a family-centered approach to tobacco control issues that affect children. Previously, she has been involved in a number of epidemiologic studies examining parents' patterns of smoking and cessation attempts, parents' rules against smoking in homes and vehicles, and parents' attitudes towards pediatric practitioners' advice and assistance with quit attempts.

She also studies hospitalizations for respiratory illness, and the impact of SHS on inflammatory markers and development of asthma in children hospitalized for bronchiolitis. She has an R01 from the National Cancer Institute to study an inpatient parent cessation and exposure reduction intervention, and she is PI of the AAP Richmond Center Respiratory Illness and Secondhand Smoke Exposure in Kids (RISSK) project which studies biomarkers of inflammation in smoke-exposed children, and a Co-PI on the AAP Richmond Center Measurement Core project.
