Biopic and Research

After completing my MEng degree in Aerospace engineering here at the University of Sheffield, I joined the Department of Automatic Control and Systems Engineering in 2013 to pursue a PhD in fluid flow control. My research focuses on developing techniques for deriving low order models of fluid flows around complex geometries such as bluff body flows, for the application of feedback control in order to reduce pressure drag.

I received an EPSRC doctoral training award to fund my research, and am supervised by Dr Bryn Jones.

Other Activities

As well as carrying out my research, I act as an Associate Tutor for a number of undergraduate and Masters degree modules, assisting in computer labs/tutorials and conducting oral examinations. These modules include:
FCE120 – Introduction to Aerospace Design
ACS317/6102 – State-space Control Design
ACS424 – Multi-Sensor Data Fusion
ACS427 – Data Modelling and Machine Learning
