This page the primary landing page for calculators I have built for COVID-19-related subjects. It also contains information that I have found useful in my work on COVID-19 policy analysis and modeling.
Software for COVID-19 risk analysis
- Risk Stratification Workbench a simple policy design tool for evaluating Total Harm Minimization strategies for restarting the economy with as little negative health impact as possible (beta).

Quick Start Guide (Cheat Sheet)
Handbook for population risk-stratification, reopening, and triage (can be used with software)
- Drawing the line for risk stratifications: Designing return-to-work policies that consider diagnostic error, costs, benefits and COVID-19 Stein, R. M. (2020).
- – Templates and examples that can be used to answer a number of common policy questions.
- – Additional material for answering questions not currently included in Risk Stratification Workbenchbook
- – Executive Summary
- – Detail behind Risk Stratification Workbench

- The True Health Initiative Total Harm Minimization Project: A collection of research and references relating to approaches that policy makers can use to implement total harm minimization strategies that consider both direct and indirect pandemic harms and seeks to reduce both to the irreducible minimum. The site includes publications on how policy makers can use risk stratification models as well as a partial atlas of many quantitative epidemiological models and policy proposals.
- The COVID Tracking project: An aggregation and partial rationalization into comprehensive data sets of data on COVID-19 data from dozens of sources
- The Coronavirus Resource Center, Johns Hopkins contains information and data on many topics related to the COVID-19 pandemic, including an updated case counts, animated mapping visualizations and dashboards special queries on topics including analyses and trends by state, country, on mortality, prevalence and special topics such as racial disparity.
