AboutAbout the lab
Using mathematics to study the properties of materials and molecules
The Partial Differential Equations and Calculus of Variations Lab investigates problems in elasticity theory and functional materials, building on partial differential equations and vector-valued calculus of variations.
Its research includes mathematically modeling defects that arise in crystal lattices and using machine learning to study the properties of molecules.
The lab also studies anomalies that appear in blockchain transactions.
Professor Pierluigi Cesana is also a faculty member of the Department of Mathematics in the Graduate School of Mathematics and of the Graduate School of Mathematics for Innovation.
