Department of Mathematics and Statistics
- Jeffrey Adler conducts research mainly in harmonic analysis and representation theory (which can be thought of as the study of symmetry from a formal point of view), and also occasionally supervises undergraduate research projects in other areas. Among his non-professional interests are string quartets, urban development, etc.
