Local Spin Spin Rotations Machine Learning Battery Voltages SIC with FLOSIC FLOSIC Magnetic Molecules Spin Dynamics with TDDFT

This page contains information about our computational electronic structure work here at CMU

Areas of research

There are several opportunities for undergraduate and graduate students, especially if they are good with computers and quantum mechanics. Just contact me.


We use a new computational method to remove evil self-interaction from DFT. This is a large colaboration with UTEP, Temple, Florida, and Pittsburg.

Spin Dynamics in DFT

We use 2-components real-time dynamics to model several phenomena, including molecules out of equilibrium in collaboration with Oded Hod from Tel-aviv.

Magnetic Properties

We are always interested in modeling molecular magnetism. We work with several great people, including the team for Buenos Aires.


We transform espressos into great science. For more information check the "news" section.
