Mechanics of Fretting and Fretting Fatigue

David Hills read Engineering Science at the University of Oxford, and after a short period in industry did a PhD at what was then Trent Polytechnic, where he was made a lecturer. In 1983 he spent a very educational year at the University of Michigan with Maria Comninou and Jim Barber. In 1984 he secured an appointment in the department in which he had incepted, together with a Fellowship at Lincoln College. He has retained these positions, working mainly on fretting, fretting fatigue and contact problems generally.Hendrik N. Andresen graduated from the Technical University of Berlin with a master’s degree in 2017 and began his DPhil studies at the University of Oxford under the supervision of Prof David A. Hills in the field of contact mechanics the same year. During his studies he gained invaluable professional experience in the automotive and aerospace industries and participated in an exchange programme with the University of Michigan. In 2019 he was a stipendiary lecturer at Lincoln College. He is now pursuing a career in intellectual property law in Berlin.
