Char Hilgers

Char Hilgers is a PhD student in Sociology at the Humboldt University's Berlin Graduate School of Social Science, funded by the Socio-Economic Panel at DIW Berlin. Their research is on statistical techniques for nonresponse in survey settings: when missingness means something. From multiple imputation for handling missing not at random, to the data integration of probability and non-probability surveys. They are interested in refusal, misdirection, and obfuscation in survey settings, and ethical dilemmas around these. They hold a Master's in Industrial and Applied Mathematics and a Bachelor's in Pure Mathematics, and they have worked as a data scientist in forest monitoring, epidemiology, and supply chain forecasting.
