What We Do

Aero Data Lab works on projects at the intersection of data science, epistemology, and ethics. We use skills in programming, evidence synthesis, data visualization, and philosophy of science to generate new insights from complex or unstructured datasets—transforming data into knowledge. Then we use expertise in ethics to help transform that knowledge into action and policy.


Much of our work is intended for publication in the academic literature or for the private use of our clients. However, we do host some projects here on this site, which you can browse below.
