Research Interests

I am currently working on glass micro machining using electrochemical discharge phenomenon. The final goal of my work is to extend the capabilities of spark assisted chemical engraving (SACE) by integrating additive manufacturing (AM) techniques and SACE. The motivation behind this is to develop a novel manufacturing technology having more flexibility and enhanced control for fabrication of devices integrating nano- and microstructures such as biosensing devices like localized surface Plasmon resonators (LSPRs).

My research interests include additive manufacturing, non-conventional micromachining techniques and micro-/nano systems.
