Theoretical Soft Condensed Matter * Programmable Self-assembly * Bio-inspired Nanoscience * Statistical Physics
By combining analytical methods of statistical physics with computer simulations, and working closely with my experimental collaborators, I explore the area of Programmable Self-Assembly. My other interests span across various fields of statistical mechanics, condensed matter, and bio-inspired physics, from entropic phenomena in solids to Foundations of Quantum Mechanics, Origin of Life, and (motivated by certain recent events) Epidemic Modeling.
CFN is both the research center and User Facility with the focus on experimental and computational tools for nanoscience, and excellent on-site expertise. We are always looking for new users and potential collaborators. Learn more here
