Ph.D. dissertation: "Experimental and Numerical Investigations of the Physical Processes in a Co-Axial Magneto-Isolated Longitudinal Anode Hall Thruster".

Investigated the discharge physics in a new type of low power Hall thruster (CAMILA) by means of a laboratory model and a computer generated model. The experimental work was conducted using electrical probes, inside the thruster channel. A numerical model was created based on the particle-in-cell method. The aim of the research was to enable better propulsion options for small spacecraft.

M.Sc. thesis: "Field Emission Cathode for use in Electric Propulsion".

Developed a new concept of cathode for use in Hall effect thrusters - the field emission acceleration-deceleration cathode. Both numerical (particle-in-cell) and analytical methods were employed.
