Associate Professor, Civil Struct & Env. Eng.

Biography

Dermot O'Dwyer graduated with a 1st Class Honours degree in Civil Engineering from UCG in 1989. In 1991 he completed a research masters on the limit-state analysis of masony vaults. From 1991-1993 he worked as a structural engineer design structures varyling from water towers and treatment tanks to multi-storey apartments and industrial buildings in a variety of materials. He became a chartered engineer in 1993. In 1993 he joined Irish Rail. Within Irish Rail he worked in the technical office working on a range of topics from the development of new switch geometries to budget planning. While in Irish Rail he was secunded to the Light Rail office. In 1995 he joined the Department of Civil, Structural and Environmental Engineering in Trinity College Dublin. He was awarded a PhD in 2001 for the thesis "The Application of Genetic Algorithms to Civil Engineering Optimisation Problems".
