Nikhil Jayakumar

Nikhil Jayakumar serves as a Research Fellow in the Department of Physics and Technology at UiT The Arctic University of Norway, Tromsø, and is an active member of the Optical Nanoscopy research group. His work bridges photonics and biomedical imaging through innovative waveguide-based microscopy platforms.

Dr. Jayakumar's research centers on optical waveguides and interference microscopy, with core expertise in developing label-free imaging systems. His work on multi-moded high-index contrast waveguides (2022) achieved unprecedented contrast in microscopy, while dynamic speckle illumination techniques (2022-2023) enabled new approaches to quantitative phase imaging. The 2025 aluminum oxide waveguide platform represents a significant advancement in low-background on-chip microscopy.

His publication record shows consistent output in top optics journals since 2019, with 15 articles demonstrating expertise in waveguide design, speckle-based imaging, and quantitative phase microscopy. Current work focuses on integrating waveguide technology with microfluidics for live-cell nanoscopy applications.

Dr. Jayakumar collaborates extensively within the Optical Nanoscopy group, contributing to projects that combine photonics, computational imaging, and biomedical applications. His research has practical implications for drug delivery characterization (liposome studies) and cellular dynamics analysis.
