Biography
In 1996, I got my PhD in Physics from the Australian National University. My dissertation’s title is “Studies of vacuum magnetic surfaces in H-1 using tomography”. I primarily trained in Experimental Plasma Physics and Instrumentation. Later, I worked on microwave-based atmospheric plasma devices for materials processing such as surface modifications and thin film deposition. I got my B.S. Physics in 1985 from U.P. Diliman.
