Qianhan (Lanlan) Liu

Lanlan Liu is a fourth-year Ph.D. candidate in the Applied Mathematics research group and a first-year BU URBAN trainee. Originally from Jiangsu, China, she obtained her Bachelor’s degree in Mathematics (with minors in German and Computer Science) from Vanderbilt University. At Vanderbilt, she did her undergraduate thesis in number theory, studying the representation of numbers as sums of squares. In the summer of her junior year, she served as a research assistant at the Sobolev Institute of Mathematics to study the semi-supervised classification of hyperspectral images. In her first two summer terms at BU, she was the instructor for courses MA 121 Calculus for the Life and Social Sciences I and MA 581 Probability. Lanlan’s research interests include stochastic processes and differential equations, and she is currently working with her advisors Konstantinos Spiliopoulos and Sam Isaacson on the mean field limit of particular-based stochastic reaction-diffusion models with potentials. When she is not buried in mathematical proofs, Lanlan loves shooting instant photos and storing life’s precious moments in albums. She recently got a Cavachon boy Milo, who already had an album of his own!
