Meet the Scientists

Our team of Yale University researchers includes faculty, PhD researchers, and college students. At the bottom of this page, you can learn more about Dr. Frank Keil (chair of the Psychology Department at Yale and head of one of the development labs) and Dr. Mark Sheskin (head of online research at

But first, this “day in the life of a scientist” gallery features many of our researchers working on different parts of the research process:

Dr. Frank Keil

Professor Keil is the professor in charge of the Cognition and Development Lab at Yale University. He received his PhD from the University of Pennsylvania. He taught at Cornell before joining Yale in 1998. In addition to heading the lab, he is currently chair of the Yale Psychology Department.

At the most general level, Professor Keil’s research is about how children make sense of the world around them. His research involves asking how intuitive explanations and understandings emerge in development, and how they are related to ideas about cause, mechanism and agency. These specific questions are related to broader questions about what concepts are, how concepts change when children get older and learn more, and how concepts are structured in adult minds.

Dr. Mark Sheskin

Mark is a postdoctoral researcher at Yale, and leads the Online Research Team at He received his PhD in developmental psychology from Yale University in 2013. From 2013-2015, he lived in Paris as a researcher at Ecole Normale Superieure. Now, he is back at Yale, as a teacher and researcher in the Cognitive Science Program. He also has the world’s best dog (see picture to the right).

Mark’s research looks at the preferences children have for different types of explanation, and the development of prosocial behavior across childhood, adolescence, and adulthood. He is excited to learn from a wide range of families who participate at The Child Lab.
