David E. Joyce

David E. Joyce is a Professor in the Department of Mathematics and Computer Science at Clark University. His work spans pure and applied mathematics, with a focus on geometry, algebra, and chaos theory. He has developed extensive online educational resources, including interactive explorations of Euclid's Elements, trigonometry, complex numbers, and fractal generation tools like Millefiori! and Newton Basins.

• Research Highlights: Symmetry in mathematics, knot theory, hyperbolic plane tiling, and computational visualization.
• Education Projects: Created digital courses on trigonometry, complex numbers, and Hilbert's 23 problems.
• Technical Contributions: Maintains the Huxley File (T.H. Huxley works), explores phylogeny reconstruction, and developed Java-based interactive geometry applications.
