Professor of Human Development, Cornell University

Currently, with Wendy Williams, I am in the throes of a major project examining sex differences in cognitive performance, which has culminated this year in several new peer-reviewed articles (eg, American Scientist) and chapters. We also created the Cornell Institute for Women in Science (CIWS) web page, and gave a large number of media interviews.

I continue to develop my bio-ecological theory of intelligence,and I continue to publish articles dealing with cognitive development (eg, memory development). And Wendy Williams and I have three large-scale national analyses of academic mentorship, hiring, and authorship issues that are currently under review. My reseaarch on children and the law also continues full-throttle, with a number of new experiments on children's false confessions (with graduate student, Amelia Hritz) and children's cryptoplagiarism (with former graduate student, Zoe Klemfuss and colleague Kamala London).

I am the author of ~400-450 articles, books, commentaries, reviews, and chapters—many in the premier journals of the field. According to Google Scholar, my work has been cited over 20,000 times and my h-index is 59, with 37 publicatiosn each cited in excess of 100 times. I have given hundreds of invited addresses and keynote speeches around the world (Harvard, Cambridge University, Oxford, Yale, Princeton, University of Rome, University of Oslo, Max Plank Institutes in both Munich and Berlin). I have served on the Advisory Board of the National Science Foundation for seven years (the Social, Behavioral, and Economic Sciences), and was a member of the National Academy of Sciences’ Board of Behavioral and Sensory Sciences for six years.
