Dr Nicholas Alexander


My main areas of interest are Earthquake Engineering, Structural Dynamics and Nonlinear dynamics. I did my undergraduate and post-graduate studies at University College London (UCL). I graduated with a 1st Class Honours degree in Civil Engineering and was awarded the Institution of Civil Engineers prize

My Ph.D. was in the field of nonlinear dynamics; were I worked on bifurcation following, computational algorithms for the investigation of nonlinear systems. The main part of this thesis was the development of algorithms for identifying and continuing invariant manifold tangencies.

After leaving UCL I worked for a Structural Engineering design consultancy before returning to academia; taking up a post at the University of East London (UEL). While at UEL I became interested in the whole area of the application of structural dynamics to the field of Earthquake Engineering. I supervised two Ph.Ds (completed) there; one in the behaviour of buildings that are subject to torsion and lateral swaying, and another in the field of nonlinear reinforced concrete frameworks with extensive experimental testing of such frames in the Laboratories at UEL. After a number of years in this field I was asked to give course of lectures in Dynamics and Earthquake Engineering at UCL on their MSc as an external lecturer. In 2003 I came to Bristol and took up a post here.

I have supervised one Ph.D (completed) here at Bristol and I am currently supervising four Ph.D. students. I have published over 50 international conference and Journal papers.

I am a member of the institute of mathematics and its applications, a Chartered Mathematician and a Chartered Scientist (Uk). I am a graduate member of the Institution of Civil Engineers.

I have reviewed papers for Journal of Sound and Vibration, ICE Buildings and Structures, Engineering Computations, Civil Engineering and Environmental Systems, Shock and Vibration, Journal of Zhejiang University Science A, Computers and Structures, Engineering Structures and Physica D

At Bristol I have developed been interested in the following areas (i) applications of nonlinear dynamics in the field of earthquake engineering (ii) development of algorithms in the accurate processing of ground motion data in order to determine robust measures of ground motion displacements  (iii) human-structure dynamic interaction problems, (iv) nonlinear soil-structure and structure-soil-structure interaction problems.
