The Emergency Law Inventory (ELI) is a tool developed by the University of Pittsburgh Graduate School of Public Health and its partners at the New York City Department of Health and Mental Hygiene, Allegheny County Health Department (Pittsburgh, Pennsylvania), and Mahoning, Columbiana, and Trumbull Counties Medical Reserve Corps (Ohio).

ELI helps individuals navigate through laws that impact volunteer participation in preparing for or responding to disasters. The inventory focuses on four area s of law: Liability, License Reciprocity, Scope of Practice, and Workers' Benefits. ELI provides over 1500 clear, concise summaries of laws in all 50 states, the District of Columbia, eight (8) U.S. territories, and the federal government. The laws are searchable by profession and jurisdiction so users can identify the provisions that impact them specifically.

Framework for Reconstructing Epidemiological Dynamics (FRED) is an open source modeling system developed by the University of Pittsburgh PublicLogo Fred Health Dynamics Laboratory in collaboration with the Pittsburgh Supercomputing Center and the School of Computer Science at Carnegie Mellon University.

FRED supports research on the dynamics of infectious disease epidemics and the interacting effects of:

  • Mitigation strategies
  • Viral evolution
  • Personal health behavior

FRED is available through open source in the hopes of making large-scale agent-based epidemic models more useful to the policy-making community, the research community, and as a teaching tool for students in public health.

The Legal Network Analyzer (LENA) and Emergency Law Database (ELDB) are tools developed by the CDC-funded University of Pittsburgh Preparedness and Emergency Response Research Center in collaboration with the University of Pittsburgh Public Health Dynamics Laboratory to help individuals understand the emergency laws that direct public health system agents to work collaboratively.

LENA presents network visualizations of the relationships among agents in the public health systems as mandated by federal and state law to participate in emergency preparation, response, and recovery. LENA can be used to compare these legally defined relationships and to access the Emergency Law Database, a searchable repository of over 5,900 laws.
