Research Interests

Research interests include: 1. Biomedical Systems: Modelling of Glucose-Insulin system, development of macro-physical cardio-vascular system models including ventricular interaction, integral based Inverse Problem Solutions for a Digital Image-Based Elasto Tomography Breast Cancer Screening System, agitation sensing with Image Processing based on patient motion and facial grimacing. 2. Image Processing and Computer Vision: High Speed 3D Motion Sensing for a Digital Image-based Elasto Tomography Breast Cancer Screening System, intensive care patient motion detection and measurement (facial grimacing detection for the development of an agitation sensor), measuring morphological change in the Waimakariri River using a rotating camera system with zoom on a 33m power pylon and on a 12m portable mast. 3.Structural Health Monitoring: Developing real time integral based structural Health Monitoring algorithms, applying integral based methods to detect stiffness changes to the structure of multi-storey buildings during and after an earthquake using only accelerometer data 4. Development of real-time modeling and system identification techniques for implementation during rocket flight, 6DOF rigid body dynamic modeling of rocket response, Minimal modeling of shock waves and turbulence during rocket flight, Vertical wind tunnel testing and control system development, Orbital mechanics calculations and optimization for small payload low earth orbit insertion
