Theoretical Soft Condensed Matter * Programmable Self-assembly * Bio-inspired Nanoscience * Statistical Physics


This site features my research as a Scientist at the Center for Functional Nanomaterials (CFN), a part of  Brookhaven National Laboratory. By combining methods of theoretical statistical physics with computer simulations, and working closely with my experimental collaborators, I explore the emerging areas of programmable self-assembly  and bio-inspired nanoscience. Some of our approaches are "biokleptic", i.e.  biomolecules such as  DNA are "borrowed" from Nature to mediate nanoparticle self-assembly or to give new functionality to engineered nano-structures. On the other hand, as the complexity of these artificially built structures increases, they start looking more and more like "living matter" and share certain organizing principles with biological systems. 

CFN is both a Research Center and a User Facility with the focus on experimental and computational tools for nanoscience, and an excellent on-site expertise. We are always looking for new users and potential collaborators. Lean more here
