Consulting

I’m open to contract work. Areas where I can help:

• Survey design and analysis: household, attitude, and KAP (knowledge, attitudes, practices) surveys, including instrument development, sampling, and enumerator training. Review of existing survey data for enumerator and measurement effects, including AI-assisted audits.
• Program monitoring and evaluation: M&E design, causal designs (experiments, difference-in-differences, matched comparisons), and quantitative analysis for behavior-change and community conservation programs.
• Evidence reviews: what has and hasn’t worked on a given problem, and whether a program is worth funding, with cost-effectiveness estimates where the data allow.
• Statistical analysis and data science: experimental design and power analysis, Bayesian and frequentist modeling, and analysis of survey, field, and time-series data in R and Python.
• Mathematical and ecological modeling: population and dynamical-systems models, optimization and dynamic programming, simulation, and machine-learning forecasting.

I worked as an independent software and data consultant from 2010 to 2016 (see CV). If something above fits a problem you’re working on: emerson.arehart@gmail.com
