• Photonic Integrated Circuits (PICs)
• Micro and nano-structuring
• Nano-fabrication
• Hybrid Platforms.

I am a Research Scientist in the Silicon Photonics group, specializing in hybrid photonic integrated circuit (PIC) integration.

I hold a Bachelor’s degree in Electronics and Communication Engineering from Visvesvaraya Technological University, India, and a Master’s degree in Photonics from the University of Eastern Finland. I earned my PhD from Laboratoire Hubert Curien, France, where my research focused on the development of grating waveguide structures for high-power laser systems. I subsequently carried out postdoctoral research at KTH Royal Institute of Technology, Stockholm, working on the hybrid integration of LiNbO₃ photonic devices on thick SOI platforms.

My expertise includes integrated photonics design and simulation, laser interference lithography, and photonic device characterization.
