    Career Interests

    I am very keen in working on spacecraft design & build, and related instrumentation. My experience during my PhD included the development of a GPS receiver-based payload (TOPCAT) for plasmaspheric science installed in UK Space Agency’s pilot CubeSat – UKube-1. I took the primary role in all stages of payload development, managing the project from design through to space qualification tests. Design and build of TOPCAT required various aspects of hardware/software, RF and mechanical engineering skills.





    University of Bath, UK

    PhD Research Programme in Electronic and Electrical Engineering

    Thesis Title: Topside Ionosphere/Plasmasphere Tomography using Space-Borne Dual Frequency GPS Receivers

    The project installed a GPS L1/L2 receiver within the CubeSat UKube-1 to measure the total electron content on the topside ionosphere and beyond. The payload was a feasibility study of technology and cost to implement a constellation of GPS receivers for continuous global monitoring of the region. The project will also validate a MATLAB-based ionospheric tomography algorithm for the topside ionosphere/plasmasphere, enabling the first phase of a complete system for global ionised upper atmospheric imaging. During my PhD I also assisted teaching academics with practical laboratories for undergraduate students and provided informal supervision to postgraduate students.




    University of Bath, UK

    MEng (Hons) Electronics with Space Science andTechnology with Industrial Placement - First-Class Honours (Average: 85.2%)

    Significant Projects Undertaken:

    (1) Group Business and Design Project (GBDP) to produce a business proposal and design a Loran receiver module – Included a Needs Analysis/Target Specification, Feasibility Study, Business Plan and Technical Detailed Design. Each team member was required to assume roles of a manager and engineer. I was the Operations Manager in charge of product operation procedures, and managing capital resources.


    (2) Final Year Individual Project (FYP) on the design of an unmanned aerial vehicle (UAV) flight controller – Included research into project specifications and design alternatives, leading to the final proposal of the design.

    Other Modules Include: Communication, Remote Sensing & Satellite Navigation Systems, Microprocessors & Digital Electronics, Space Electronics & Vehicles/Platforms

    Research Officer at the University of Bath

    Working with a Spirent GPS simulator to characterize the behavior of GPS receivers in the presence of ionospheric scintillation, with specific interest on aviation receivers that will be used for safety critical applications. Supervision of undergraduate and postgraduate students on projects related to the Spirent simulator.



    2009, 2010

    Student Fellow at the Australian Astronomical Observatory, Australia

    I was awarded three-month (2009) and six-month (2010) student fellowships to develop a control system for a self-motile fiber positioning system to transport payloads across a field plate in large telescopes. Gained experience in digital image processing and control/operation of mini robotic systems using LabVIEW. Included characterization of operating parameters and simulations via MATLAB to model the motion of the robots.



    Industrial Placement – STFC Rutherford Appleton Laboratories

    Worked as a member of a R&D team to simulate/design a vertex detector for the International Linear Collider (ILC). Tasks included optimization of detector designs through performance analysis of different sensor technologies.
