Research Interests

Vlad Cucuiet is a PhD student at Babes-Bolyai University, specializing in plasmonics and graphene-based materials for biosensing and various applications. His research focuses on understanding SERS (Surface-Enhanced Raman Spectroscopy) mechanisms and exploring the interaction between graphene-based materials plasmonic nanostructures with applications in advanced biosensing. Beyond his focus on SERS, he has gained hands-on experience with advanced analytical and synthesis techniques. His synthesis expertise includes Chemical Vapor Deposition (CVD) for the controlled production of graphene and carbon nanotubes. For analysis, he has utilized Quartz Crystal Microbalance with Dissipation (QCM-D) to investigate the viscoelastic properties of small DNA strands, successfully integrating these analyses with spectroscopic data to provide a comprehensive view on the elastic behavior of small molecules. In addition to experimental research, Vlad has a strong interest in theoretical and computational physics, particularly in electromagnetic and solid state DFT simulations, as well as quantum plasmonic effects. With a solid foundation in mathematics and theoretical physics, he also has experience in programming with Python, Gaussian and Julia, enabling him to develop and analyze advanced numerical models. His interdisciplinary expertise positions him at the intersection of nanophotonics, carbon based nanomaterials,biosensing, and computational physics."
