Professor Mitchell specializes in the behaviour and design of concrete structures. His research interests include shear and torsion design, design of disturbed regions, seismic design, seismic evaluation and retrofit, the behaviour of prestressed and high-strength concrete structures. He joined the Department of Civil Engineering and Applied Mechanics in 1976.
