Professor, Mathematical Sciences

My research has addressed problems of practical concern arising in the general area of solid and fluid mechanics, especially chemically reactive  flows of the kind that occur during combustion and explosion processes.  Recent work has focused on the development and analysis, both theoretical and computational, of models that would accurately predict the generation and propagation of detonation waves in high-energy solid explosives.  The research is carried out in collaboration with colleagues at Rensselaer and at Los Alamos and Lawrence Livermore national laboratories.
