I am a Research Scientist specializing in advanced materials, thin-film technology, semiconductor processing, nanofabrication, and integrated photonics. My expertise spans materials development, fabrication process optimization, and advanced characterization techniques, with a strong focus on translating materials research into scalable technologies for semiconductor and photonic applications.

I completed my PhD in 2026 at the Integrated Optical Systems (IOS) Group, MESA+ Institute for Nanotechnology, University of Twente. During my PhD, I focused on developing aluminum nitride (AlN) and improving aluminum oxide (Al₂O₃) as broadband integrated photonic platforms. My work involved thin-film deposition, material optimization, chemical mechanical polishing (CMP), and comprehensive structural, morphological, and optical characterization. This research contributed to the development of low-loss optical waveguides and integrated photonic devices operating across a broad wavelength range, including ultraviolet applications.

Currently, I work as a Research Scientist at the Photonic Integration Technology Centre (PITC), University of Twente, developing nanosheet-based platforms for stress-optic modulators. My research involves wafer-scale Langmuir–Blodgett deposition of 2D nanosheets, oriented growth of functional piezoelectric thin films such as PZT, and integration with Si₃N₄ photonic platforms.

I have hands-on experience in cleanroom fabrication, thin-film process optimization, SEM, AFM, XRD, and experimental data analysis. My professional interests include integrated photonics, advanced materials, semiconductor manufacturing, and the development of scalable technologies for next-generation photonic devices.
