Research / Scholarly interests
Dr Tilford is primarily focused on using numerical analysis to tackle challenges faced by UK and International engineering companies, particularly in the field of the reliability of electronics systems. He develops and utilises numerical techniques to evaluate and optimise the design of systems and manufacturing processes to improve the reliability and robustness of manufactured products. This is of critical relevance in the electronics field as the rate of progression in technologies means that evaluation of the lifetime of a commercial product is typically based on a prediction as opposed to historical data. Most recently he has been working on evaluating the reliability of additively manufactured electronics systems, aiding transition of the technology into a major multinational microelectronics company, and into assessment of Power Electronics systems utilising wide bandgap semiconductor materials which will underpin the transition to a low/zero carbon economy.
