Oanh has been working on probability theory and stochastic processes. She studies the distribution of roots of various kinds of random functions and develops the universality methods. She also investigates the phase transition of interacting particle systems and the mixing time of Markov Chains. In particular, she studies the contact process, a model for the spread of diseases on large networks. Exciting to explore new research directions and their applications, Oanh is eager to learn from the applied math community and forms new research collaborations.
