Overview
The research of the Rubinstein group is in the field of polymer theory and computer simulations. The unique properties of polymeric systems are due to the size, topology and interactions of the molecules they are made of. Our goal is to understand the properties of various polymeric systems and to design new systems with even more interesting and useful properties.
Our approach is based upon building and solving simple molecular models of different polymeric systems. The models we develop are simple enough to be solved either analytically or numerically, but contain the main features leading to unique properties of real polymers. Computer simulations of our models serve as an important bridge between analytical calculations and experiments.

Rapid self-strengthening in double-network hydrogels triggered by bond scission.
Journal Article Nature materials · April 2025 The scission of chemical bonds in materials can lead to catastrophic failure, with weak bonds typically undermining the materials' strength. Here we demonstrate how weak bonds can be leveraged to achieve self-strengthening in polymer network materials. The ... Full text CiteFracture of polymer-like networks with hybrid bond strengths
Journal Article Journal of the Mechanics and Physics of Solids · February 1, 2025 The design and functionality of polymeric materials hinge on failure resistance. While molecular-level details drive crack evolution in polymer networks, the connection between individual chain scission and bulk failure remains unclear and difficult to pro ... Full text CiteMeasuring Topological Constraint Relaxation in Ring-Linear Polymer Blends.
Journal Article Physical review letters · September 2024 Polymers are an effective test bed for studying topological constraints in condensed matter due to a wide array of synthetically available chain topologies. When linear and ring polymers are blended together, emergent rheological properties are observed as ... Full text CiteRecent Grants
