Tatevik Chalyan is a postdoctoral researcher in the Brussels Photonics Team at the Vrije Universiteit Brussel, Belgium. Her research interests cover the fields of biophotonics and optical biosensing. Her work focuses on the nanofabrication and development of plasmonic substrates for surface-enhanced Raman spectroscopy and fluorescence microscopy, as well as the study of microring resonators and interferometer-based biosensors for refractive index sensing, optofluidic design, and validation. Moreover, she is an Optica Ambassador.
