Before joining Kolisch Hartwell in 2000, Stan gained more than ten years of post-graduate research experience in the biological sciences. Between 1995 and 2000, he was a principal investigator at Oregon Health & Science University (OHSU), while studying mechanisms of gene memory. Between 1988 and 1995, he conducted postdoctoral research with two members of the National Academy of Sciences, including studies at the Salk Institute on nuclear receptors and at the Fred Hutchinson Cancer Research Center on master regulatory genes. He has co-authored more than 25 peer-reviewed publications and is a co-inventor on 11 U.S. patents.<
