Natrajan's group develops luminescent lanthanide complexes for chemical and biological sensing. Research directions: (1) Time-gated lanthanide luminescence sensing — long-lifetime Eu3+, Tb3+, and Yb3+ complexes with millisecond emission lifetimes for background-free sensing in cells and tissue; (2) Intracellular sensing — luminescent probes for sensing O2, pH, viscosity, and specific enzymes inside living cells with spatiotemporal resolution; (3) Chiral discrimination — circularly polarized luminescence (CPL) from Eu3+ complexes for enantioselective sensing; (4) Responsive probes — switchable lanthanide complexes as ratiometric sensors for biomedical imaging. The long-lifetime emission enables time-gating strategies analogous to quantum sensing protocols.

Parkinson's group uses ultrafast optical spectroscopy to study carrier dynamics in photonic materials with quantum device applications. Research directions: (1) Time-resolved photoluminescence — TRPL with single-photon counting to map exciton lifetimes, diffusion, and defect trapping in GaN, perovskite, and 2D semiconductor quantum wells; (2) Optical single-particle spectroscopy — isolating single nanowires or nanocrystals for defect-free measurements of intrinsic optical properties; (3) Photon-number statistics — Hanbury Brown–Twiss measurements of single-photon purity from quantum dots and localized excitons; (4) Semiconductor quantum sensing interfaces — studying how carrier dynamics affect the fidelity of semiconductor-based quantum sensors and emitters.
