Through her groundbreaking Master’s research at Queen’s University, Oluwatola Oyinlola Alabi has pioneered a simulation framework that is set to transform how scientists design and understand self-assembling systems. Her algorithm—shape-targeted alchemical Monte Carlo—replaces passive observation with guided synthesis, giving researchers unprecedented control over the outcome of material behavior. The advantages are far-reaching: faster discovery cycles, tailored structural properties, and the ability to craft materials with built-in functionality. Her identification of a never-before-seen hierarchical structure showcases the technique’s potential to unlock new classes of materials across disciplines from biophysics to smart textiles.
Alabi’s work addresses one of the central challenges in materials science: how to predict and control the complex processes by which particles organize themselves into larger structures. Traditionally, researchers have observed self-assembly with the hope of uncovering useful or interesting patterns. However, this method often yields limited results and offers little control over the final structure. By contrast, Alabi’s algorithm introduces a way to define a target configuration and then systematically direct the system to achieve it. This active approach empowers scientists to fine-tune materials from the bottom up.
Her use of shape as a design input is particularly powerful. By treating particle geometry not just as a constraint but as a tool, Alabi’s algorithm enables researchers to engineer specific interactions that promote the formation of desired structures. This strategy provides greater control over the resulting material properties, making it possible to design systems that respond to stimuli, change shape, or perform specific functions.
Her identification of a never-before-seen hierarchical structure using this method stands as a powerful demonstration of the technique’s potential. The structure displayed complex organization across multiple scales—a feature that’s often sought after but rarely achieved in self-assembling systems. Its discovery suggests that Alabi’s approach can do more than optimize known behaviors; it can reveal entirely new classes of materials with novel functionalities, applicable across fields such as biophysics, nanomedicine, robotics, and smart textiles.
In a breakthrough poised to reshape materials science, Oluwatola Oyinlola Alabi has developed a simulation framework that gives researchers unprecedented control over self-assembling systems. Her method replaces passive observation with guided synthesis, enabling the creation of customizable, functional materials. The discovery of a novel hierarchical structure signals vast potential across fields like nanomedicine, robotics, and engineering.
