After earning a PhD in Philosophy of Science, I am now working alongside scientists in Professor Eric Turkheimer's human behavior genetics laboratory. On the one hand, I conduct quantitative statistical analyses of human twin data on everything from the heritability of Body Mass Index (BMI) to the effects of socioeconomic status (SES) on IQ. I'm currently working on a project that demonstrates how the effect of SES on IQ is quadratic, which sadly suggests that poverty hurts intelligence more than affluence helps it. On the other hand, I use philosophical training to address the conceptual challenges that are not amenable to empirical investigation, such as the nature of human intelligence and interpretation of the controversial results of human behavior genetics. For example, Eric Turkheimer and I are currently combining our empirical and philosophical talents to tackle one of the most vexing problem in modern biology: the missing heritability problem. The problem, which has challenged scientists since the completion of the human genome project, arises from conflicting results between different scientific approaches to understanding the complex relationship between genes and behavior. Where traditional methods suggest complex behavior, such as intelligence, is largely genetic, modern molecular genetics consistently struggles to identify underlying genes. Part of the problem, we argue, is that the missing heritability problem has many faces across the sciences. We mitigate the issue by offering a careful characterization of the three facets of the problem -- heritability, prediction, and mechanism -- which permits a more directed approach to its resolution.
Because current policies are informed by current science, it is of the utmost importance that we achieve a firm understanding of the strengths and weaknesses of the variety of different ways that we investigate the world and build evidence for our hypotheses about it. Much of my previous and current research, for example, seeks to characterize the nature of contemporary investigation and understanding of evolution. Traditionally this has been done by scientists and philosophers by tracking what is obvious: the explicit visual representations and diagrams depicted in journal publications and textbooks. I have shown, however, that there is far more to scientific understanding than what meets the eye. My unique approach is to look 'under the hood' and elucidate the various styles of scientific reasoning that drive current understanding of the world. In my (2015) paper "Embedded Mechanisms and Phylogenetic" I show, for example, that although phylogenetic tree hypotheses are in no obvious way mechanistic, the mathematical and statistical models that generate them are driven by mechanistic reasoning about the world. More recently, in my forthcoming paper "On Mechanistic Reasoning in Unexpected Places: the case of population genetics" I demonstrate how the seemingly nonmechanistic field of statistical population genetics is genuinely integrated with a host of mechanistic approaches in current efforts to build evidence for hypotheses regarding adaptive evolution.
