I am interested developing and validating new models and computational methods for simulating the behavior of multiphase processes, particularly as they relate to important technological problems such as nanoparticle and advanced materials synthesis, enhanced oil recovery and aquifer remediation, and development of novel reaction engineering and separation approaches for algaculture.
