Profile

Modeling and simulation techniques have enabled companies to diagnose and solve problems before any expensive prototypes are built. But with the increase in complexity of cyber physical systems, companies have to divide and conquer: they have to develop different components concurrently and they have to do business with specialized suppliers. Now it becomes harder to develop systems first time right because different teams will use different tools to build their models and the suppliers will not be willing to give away detailed models in order to protect their intellectual property.

 

A solution is to establish a common interface that allows multiple simulation tools to talk to each other without revealing the details of the models being simulated. This is co-simulation, my main research interest. From an academic point-of-view, co-simulation presents a unique set of research challenges that span mostly from the fact the connecting different simulators (of different formalisms) together amounts to create an ad-hoc hybrid modeling language. It is well known that simulation of dynamic systems can only be an approximation of the exact behaviour described in the differential equations. When coupling dynamic systems simulators, how can we trust the results? How accurate are these?

 

These are just some of the questions that make co-simulation an interesting area of research.

 

Research Interests
Past research interests include model driven engineering, optimization and verification of model
transformations.
Current and future research interests include co-simulation and its combination with numerical
analysis, physics, formal methods, and applied mathematics.
