I am an economist working at the intersection of Bayesian statistics, time-series econometrics, and applied demography, with a focus on disability and retirement policy. This site collects my published papers; a pair of continually developed knowledge wikis that reflect my research focus over a 21+ year career at the Social Security Administration; and a range of hands-on model implementations in Python and R that put those interests into practice — including replications of seminal articles across the relevant literatures.
