Boleslaw Mikolajczak, professor and chair of the Computer and Information Department, College of Engineering, University of Massachusetts, Dartmouth, MA 02747, USA, is a researcher in formal conceptual modeling of computational processes, sequential as well as parallel and distributed. For the first he applies finite state machines. For the second he uses various forms of Petri nets. He is an author of several books, many journal and conference publications devoted to studies of models of computa- tions and their applications to software and systems’ development. In particular, he is an author of an algorithm, both sequential and parallel, that computes all generalized homomorphisms (or partitions) between two finite state machines. This algorithm leads to optimized decompositions of model-based software systems. Recently he applied conceptual modeling techniques to medical guidelines modeling with colored Petri nets. The objective of this research is to improve quality of medical procedures from patients perspective and efficiency of these procedures.
