Research Information

Research Overview

I am interested in the following research topics:

(1) Identification of two-level systems in amorphous alumina. See a
metadynamics simulation of a bistable motif that behaves as a TLS in Al2O3 glass at 5 K (oxygen [aluminum] atoms are the red or magenta [grey] spheres). Click here for a short summary and here for an illustrative figure. Click here for more details.
(2) Hydrogen-bonded liquids: structure and dynamics. Confined water in carbon nanotubes: optics and dynamics.
(3) Path integrals in quantum mechanics:
development of novel algorithms and applications to complex systems.
(4) Molecular pseudo-potential theory.
(5) Novel integrators for molecular dynamics.
(6) Methods to compute free energy differences in complex systems (umbrella sampling, metadynamics, blue-moon ensemble, lambda dynamics, etc).
(7) Algorithms in quantum chemistry to describe electronic correlation.
(8) Phase transitions and nucleation theory in bulk systems.
(9) Thermal conductivity of carbon nanotubes.
(10) Applications of machine learning/compressed-sensing to chemistry: See our poster.
(11) Electronic properties of wet metal surfaces. Reactivity of organic molecules on metal surfaces. STM and AFM simulation.
