Sokolov develops femtosecond adaptive spectroscopic techniques for coherent Raman (FAST CARS), broadband stochastic laser fields, and quantum-light probes of molecular coherence for standoff chemical/biological sensing and label-free imaging. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work contributes ultrafast coherent-Raman methodology adjacent to spin-based sensing.
Develops multidimensional coherent spectroscopy methods, including label-free multidimensional optical imaging/contrast techniques applied to cancerous tissue and nanoscale heterostructures.
Develops multidimensional (2D IR/visible) ultrafast spectroscopy and new ultrafast optical microscopies, applying temporally- and spatially-resolved coherent spectroscopy to protein structure/dynamics and label-free tissue imaging.
