Research & Publications

Research Summary

Dr. Pollack’s research focuses on two areas.  First, his research investigates social determinants of health and housing policy.  He currently co-leads a NIH-funded project to investigate whether housing mobility is linked with improvement’s in children’s asthma and is principal investigator of a project to link the Moving To Opportunity social experiment with data on health care utilization (funded by RWJF).  Previous research has leveraged a natural experiment to study the impact of mixed income housing on social networks and health (funded by the MacArthur Foundation) and has studied the links between home ownership, foreclosure and health. 

His second line of research focuses on improving the delivery of cancer screening and care .  He is particularly interested in how patient and physician social networks impact decision-making and care coordination.  He co-leads a project investigating the link between physicians’ experiences in their social networks and recommendations for breast cancer screening, and he has been using large datasets to study issues around the adoption of guideline concordant care.  As the Johns Hopkins site lead for the Movember Foundation TrueNTH initiative, he works on multiple projects to improve care for men with prostate cancer.
