Shira Mitchell is a statistician who collaborated with HRDAG during her dissertation and continues to today. She developed Bayesian hierarchical models for estimating numbers of casualties for the armed conflict in Colombia. Shira received her PhD in biostatistics and a BA in mathematics from Harvard University. After her postdoc at Columbia, she worked at Mathematica Policy Research on small area estimation and causal inference for federal agencies. She then worked at the NYC Mayor’s Office of Data Analytics. Now she is a statistician at Blue Rose Research, developing Bayesian models to reduce survey non-response bias in polls.

Our work has been used by truth commissions, international criminal tribunals, and non-governmental human rights organizations. We have worked with partners on projects on five continents.
