In this talk, I briefly review some recent developments in numerical approach to structure, folding and aggregation of proteins. The topics under discussion include: (1) developments of algorithms and computer packages for all-atom simulations of proteins [1], (2) development of algorithm to compute volume V, surface area A, and cavity of proteins by analytic equations [2], (3) unfolding and refolding of immunoglobulin domain I27 and ubiquitin [3], and (4) simple models for relaxation and aggregation of proteins [4,5].
