Dr Frederic Cegla is a lecturer in the department of mechanical engineering and member of the dynamics and non-destructive evaluation (NDE) groups. After obtaining his PhD at Imperial College he worked as a postdoc at the University of Queensland in Brisbane Australia on scattering of guided waves. This was the foundation of work on guided wave scattering from real corrosion patches and guided wave structural health monitoring (SHM) that he later carried out at Imperial College.

On his return to Imperial College he has also led the work on high temperature ultrasonic monitoring in the Imperial NDE group that resulted in the formation of Permasense Ltd, a spin out company that provides wireless ultrasonic corrosion monitoring systems to the oil and gas industry.

His research interests are in the fields of high temperature ultrasonic monitoring, structural health monitoring, ultrasonic material property measurements and ultrasonic transducers.

 He is also interested in the manipulation of bubbles in ultrasonic fields and has led an industry funded project in collaboration with the Univeristy of Goettingen in Germany and TU Vienna in Austria that explored the use of cleaning semi-conductors with acoustically stimulated bubbles.
