About Us

The State Firearm Laws project aims to provide researchers with the data necessary to evaluate the effectiveness of various firearm laws. By carefully monitoring how gun legislation impacts firearm-related violence, we can provide policymakers with the evidence they need to make gun ownership safer for everyone.

Our team is led by Dr. Michael Siegel, a Professor in the Community Health Sciences Department of the Boston University School of Public Health. Dr. Michael Siegel has extensive experience in firearms research, having published eight articles regarding the relationship between gun ownership and firearm violence.

The State Firearm Laws team is headquartered in Boston, Massachusetts. For more information, contact:
