During and after obtaining his Ph.D. he worked with UB's MCEER researchers and co-authored nine technical reports for the Multidisciplinary Center for Earthquake Engineering Research (MCEER) with Andrei M Reinhorn and Michael Constantinou and other collaborators on three different federal grants. He developed the 3-D BASIS class of computer programs for the response-history analysis of seismically isolated buildings while researching through MCEER. These programs featured developments that Computers and Structures later adopted to develop the widely used programs, SAP2000 and ETABS.
