Summary

 

Summary

I am a Senior Lecturer in the Department of Aeronautics. The focus of my research group is to develop now computational optimization methods to interrogate, model and improve the performance of fluid mechanical systems. Particular applications include active control of bluff-body flows, data-driven flow modelling, aeroservoelastics, and the developement of automatic methods to rigorously bound fundamental properties of hydrodynamical systems. 

More detailed descriptions of the these research topics can be found here: our lab homepage
