I am interested in how societies become numerate and literate by using and modifying material forms over generations of collaborative effort; the effect this elaborational mechanism has on conceptual content; how material forms become increasingly refined to elicit specific behavioral and psychological responses; and what this might augur for human cognitive evolution in the past, present, and future. I have also written about the cognitive significance of Paleolithic stone tools, how Neandertal cognition differed from that of our ancestors, and the literary works of Jane Austen.

I earned my doctorate in archaeology in 2016 at the University of Oxford as a Clarendon scholar. I have a master's in psychology (2013) and a bachelor's in anthropology, philosophy, and English (2010) from the University of Colorado, Colorado Springs (UCCS). In addition to my postdoc research at the University of Bergen, I am on the faculty of the UCCS Center for Cognitive Archaeology. I am the proud grandma of two granddaughters, one 16 (my daughter's daughter) and the other coming up for 2 (my son's daughter). In my picture you see the top of the younger one's head; as you might see, she is a tad ginger. I like this picture, which was taken by my son, because it catches me in something other than my habitual scowl. My nickname is Leee. Yes, I do spell it with three e's, though the last one is silent, which is really no sillier than the silent "igh" on the end of Karenleigh.
I am currently researching the role of materiality in numerical cognition at the University of Bergen, Norway under an MSCA individual fellowship awarded by the EU (project 785793). The project aims to compare Ancient Near Eastern numeracy and material artifacts for counting to those of Oceania (Polynesia, Micronesia, and Melanesia), with the hope of gaining new insights into numerical cognition, both ancient and modern.
