This workshop will bring together researchers from diverse disciplinary backgrounds to (i) review the existing approaches on the mathematics and modeling of gun violence, (ii) identify and prioritize areas in the field that require further research, (iii) develop cross-disciplinary collaborations to gain new perspectives, and (iv) suggest research and data-collection that could assist evidence-based policy recommendations. A direct outcome from this workshop will be a comprehensive review of existing models on this topic with suggestions for further effort. It is expected that collaborations arising from the workshop will result in novel efforts to enhance the quantitative underpinnings of the science of gun violence.
