Dr Cegla aims to solve real world industrial problems through innovative application of scientific and technological principles that arise from within the research community. He has performed fundamental scientific studies but also has experience in delivering consultancy projects to industrial partners and in commercialising research findings.

Dr Cegla leads many of the activities of the Non-Destructive Evaluation (NDE) research group ( that are focused on experimental measurement and monitoring of defects and structural properties of engineering components. He is the holder of a prestigious EPSRC funded fellowship on non-destructive monitoring of engineering infrastructure and leads Imperial’s input into the £36million ORCA hub for robotics and AI in harsh environments (

One of the key successes of Dr Cegla’s research so far was the formation of the spin off company Permasense Ltd ( which has become the worldwide number one provider of ultrasonic corrosion monitoring systems to the oil and gas industry. For this and his other contributions Dr Cegla has been awarded several prizes and received publicity.

He has experience of being a researcher at Imperial College London and the University of Queensland in Brisbane, Australia. Frederic is a key contributor to the UK RCNDE that consists of many industrial members and 6 UK universities (Imperial, Bristol, Manchester, Nottingham, Warwick and Strathclyde).

Dr Cegla is an active member of the Institute of Physics (IOP) and is currently the chair of the Physical Acoustics Group (PAG) that aims to advance and disseminate advanced knowledge in the field of physical acoustics.
