Research Interests

Diffractive imaging using Free Electron Laser sources involves high-energy photons that invariably trigger a cascade of multi-electronic processes. I am developing a theoretical framework describing such non-equilibrium processes involved in single-particle imaging. The theory will also be extended to ultrafast electron diffraction.

Entangled photons, characterized by non-classical mode correlations, enable the probing of molecular properties in novel spectral-temporal regimes. I am extending the theory of multidimensional spectroscopy to accommodate correlated photonic fields and interferometric schemes.

Localized electromagnetic modes, via transverse and longitudinal components, can alter the nature of intermolecular interactions at the nanoscale and allow spectroscopic discrimination of molecular processes. I am developing theories for the predictive generation of such spatiotemporal electromagnetic potentials.

Open-loop quantum control algorithms routinely underperform in the presence of dissipative channels due to the neglect of driving and dissipation at the same footing. I am interested in developing open-loop and coherent feedback control techniques based on field-modulated spectral functions. 

Probing correlated matter by the selective generation of nonlinear polarization is at the heart of quantum-controlled spectroscopy and imaging. I am developing theoretical schemes to merge data-driven learning algorithms with the theory of pulse shaping and spectroscopy.

The ab initio simulation of multi-time, nonlinear response functions of quantum systems interacting with localized electromagnetic modes is computationally challenging. I am developing theories that will lead to efficient computational algorithms for extended systems.

Variational quantum algorithms, being hardware-governed protocols at its core, leave ample room for pulse-level improvements. I am developing strategies to amplify or attenuate specific variational paths, enhancing their performance and flexibility.

Interacting vibrational modes in a constrained environment often display counterintuitive, non-statistical energy dispersal in adsorbed molecules relevant to heterogeneous catalysis. I am developing highly scalable, master equation-based simulation protocols to describe them.
