About

My research interests lie in the broad area of Linear and Nonlinear Structural Dynamics and Control. Aeroelasticity (and the control of aeroelastic systems), in particular, has been my most recent area of research. In this area, I study the dynamic behaviour of aeroelastic systems, and research linear and nonlinear control methods (e.g. Feedback linearisation, Pole-placement). I am also interested in the study of the dynamics of non-smooth nonlinear systems (structural and aeroelastic) and their control.

Taught Modules

EG-131 Strength of Materials (Mech & Med & Engineering)

The aim of the module is to gain understanding into how engineering structures and components transmit loads and other external actions by means of internal stresses and how these stresses lead to strains and displacements. The course aims to explain the simple models of beam behaviour, concepts such as Mohr circle of stress and the relationships between stress and strain. Relevant case studies will be used to illustrate the importance of these subject areas.
EG-166 Engineering Mechanics (Aero & Civil)

This module aims to provide the students with the basic knowledge of the fundamental concepts of statics, including force, moment/couple, resultant force and resultant moment of a general force-couple system, equilibrium conditions/equations of a force system, common types of constraints/supports, and free body diagram, and by applying these concepts, the students will be able to solve statically determined truss structures using the methods of joints and sections.
EGA126 Applied Mechanics (Aero and Civil)

This module aims to provide the students with the basic knowledge of the fundamental concepts of statics, including force, moment/couple, resultant force and resultant moment of a general force-couple system, equilibrium conditions/equations of a force system, common types of constraints/supports, and free body diagrams. Engineering structures and components transmit loads and other external actions by means of internal stresses and how these stresses lead to strains and displacements; concepts such as Mohr circle of stress and the relationships between stress and strain. By applying these concepts, the students will be able to solve statically determined: truss structures (using the methods of joints and sections) and beam structures (using the simple models of beam behaviour).
EGA228 Aerospace Control

The module introduces the topic of feedback control systems and presents methods of modelling that lead to transient, steady state and stability performances in control systems. An emphasis is placed on links between time responses and complex frequency domains. Principal topics are feedback systems, Bode, Nyquist and root-locus analysis, stability conditions and compensation design. The overall aim is to understand and be able to apply basic techniques for the analysis and design of feedback control systems.
