Donald Murre

I am an independent researcher and a tax lawyer. I work on making AI retrieval reliable where a wrong answer has a cost.

My background is tax law, and I work in international tax and the taxation of investments. For ten years I have also written code: NLP, machine learning, and quantitative trading algorithms on QuantConnect. I now research how retrieval systems fail in law, tax and finance.
