Valentina Harizanov is a Professor of Mathematics at the George Washington University. Her main research contributions are in computable structure theory (roughly at the intersection of computability theory and model theory), where she introduced the notion of degree spectra of relations on computable structures and obtained first significant results concerning uncountable, countable and finite Turing degree spectra.^{[1]} Her recent interests include algorithmic learning theory and spaces of orders on groups.
She obtained BS in mathematics at the University of Belgrade, and PhD in mathematics at the University of Wisconsin–Madison under the direction of Terry Millar.
Harizanov has over 40 publication in peerreviewed journals, including
In addition, she has published the following booklength survey paper and coedited coauthored book:
Degree spectra of relations are introduced and first studied in Harizanov's dissertation:
