According to Wikipedia, Olga Kharlampovich is a Russian-Canadian mathematician working in the area of group theory. She is the Mary P. Dolciani Professor of Mathematics at the CUNY Graduate Center and Hunter College. Contributions Kharlampovich is known for her example of a finitely presented 3-step solvable group with unsolvable word problem and for the solution together with A. Myasnikov of the Tarski conjecture about equivalence of first-order theories of finitely generated non-abelian free groups and decidability of this common theory.
