“Every biological phenomenon occurs in the physical world—in space and time—and involves changes in shape, quantity and matter,” said Yarahmadian, a faculty member in MSU’s Department of Mathematics and Statistics. “Because of its abstract power, mathematics allows us to uncover patterns, test hypotheses and make predictions that may not be possible through observation alone. Mathematics does not replace laboratory or clinical research; it complements it by helping us understand the larger system, identify the most influential mechanisms and guide future experiments.”
Yarahmadian developed a framework that simulates the chain of reactions through which metals such as copper and zinc may influence amyloid-beta protein aggregation and plaque formation. The model also allows researchers to examine two potential approaches to disrupting that process. To test it, Yarahmadian and his collaborators compared its results with experimental data from atomic force microscopy, a technique used to examine microscopic aggregates.
