Dr Geetha Abeysinghe
BSc, MSc, PhD
My main research interest is in Business Process Modelling: methods for process elicitation, analysis and modelling and studying different modelling paradigms and notations and modelling tools currently in use. My other interests include: knowledge management, natural language processing, information security, and enterprise information systems.
My current research includes:
- Investigating the possibility of facilitating the process elicitation by automatic conversion of natural language process descriptions to executable process models.
- Modelling distributed guarded processes using graphical models. To this end we have developed a notation, NMDS (Notation for Modelling Distributed Systems), based on Role Activity Diagrams. NMDS was first developed to model systems specified in LIPS (Language for Implementing Parallel and distributed Systems). Work is being carried out to evaluate and modify the notation so that it will enable modelling of distributed systems in general.
- Automatic conversion of NMDS to CCS and CSP - enabling the verification of the correctness and completeness of a system specification.
- Cognitive issues in modelling.
