Research

My research focuses on quantum dynamics and spectroscopy of molecular exciton–polaritons, mixed quantum–classical methods, and open quantum systems with structured environments.

Current directions

  • Exciton–polaritons and cavity-modified spectroscopy

    Developing quantum dynamics frameworks to study linear and nonlinear spectroscopy (including 2D electronic spectroscopy) of molecular ensembles strongly coupled to optical cavities, with a focus on polaron decoupling, long-lived polaritonic coherence, and motional narrowing in disordered systems.

  • Mixed quantum–classical dynamics & mapping approaches

    Designing trajectory-based methods that combine PLDM dynamics with Lindblad formalisms to treat both Markovian and non-Markovian dissipation, and exploring spin-mapping and related mapping-based approaches to improve accuracy and efficiency for strongly coupled light–matter systems.

  • Open quantum systems & structured environments

    Studying system–bath interactions under Drude–Lorentz and underdamped Brownian spectral densities using correlation-function approaches, master equations, and analog simulations, with an eye toward connecting microscopic models with experimentally observed spectra and transport.

  • High-performance computing & scientific software

    Implementing scalable simulations using Python, C++, mpi4py, and scientific libraries such as NumPy, SciPy, Numba, PyTorch, and Eigen, enabling studies of quantum dynamics in large polaritonic systems with many molecules and cavity modes.
