Alexei Tkachenko

Alexei Tkachenko is an Adjunct Professor in Physics and Astronomy at Stony Brook University and Physicist at Brookhaven National Laboratory's Center for Functional Nanomaterials. His research program explores programmable self-assembly of matter using statistical physics approaches, biological network formation, and epidemic modeling with applications to nanomaterials and public health.

Research interests include:

• DNA-programmed nanoparticle assembly for designer nanomaterials
• Statistical physics foundations of emergent complexity in biological systems
• Development of predictive models for epidemic spread and control
• Theoretical frameworks for understanding origins of biological information

His recent publications demonstrate consistent focus on emergent phenomena across scales, from nanoparticle self-organization to population-level epidemic dynamics. The research combines theoretical modeling with computational approaches to address fundamental questions in soft matter physics and complex systems.
