I am a professor of economics at California State University Fullerton. I specialize in quantitative analysis, especially using observational data (although I have my share of experiment design experience as well). I have ten years of experience using Stata, and can help you with any Stata coding issues you have, or can help you learn Stata yourself. I can also help with coding in some other software packages: R, Matlab, and Python. But I have less experience with those.
