The Leonardo Abstracts Service (LABS) is an evolving, comprehensive database of thesis abstracts (PhD, Master's and MFA) on topics at the intersections between art, science and technology. This English-language database is hosted by Pomona College (Claremont, CA), under the direction of editor-in-chief Sheila Pinkel. Each year, in addition to being published in the database, a selection of abstracts chosen by a peer review panel for their special relevance are published annually on our website. We are pleased to present below the top-ranked thesis abstracts of 2020, and we congratulate the authors of the theses.
