Recent publications include several reports of the National Research Council and journal publications about grade retention, academic achievement, educational expectations, social mobility, obesity, cognitive functioning, end-of-life planning, mortality, and genetic effects (and non-effects) on educational attainment, health, and cognitive functioning.
