Many problems in engineering and science are very nonlinear in nature and have strong variabilities covering many intrinsic time and spatial scales. Numerical simulation of such problems requires either the use of highly adaptive numerical algorithms or the use of reduced models that capture “important” physics of the problem at a lower cost.   Prof. Vasilyev's research focuses on the creation of novel approaches for numerical simulation of complex multi-scale phenomena, development of low order “physics-capturing” models, and applications of these novel approaches to challenging multi-scale problems of engineering and scientific interest.
