Areas of Research
My research focuses on plasma-based ion beams, exploring advanced methods like nonlinear demagnification and micro-glass capillary guiding to enhance beam performance for nanofabrication. Additionally, I investigate quantum phenomena in cryogenic ion beams, utilizing diffraction and interferometry to develop high-precision quantum sensors and probe ion-matter interactions at nanoscale and quantum levels.
