Professor, James J. Farley Professorship in Natural Philosophy
Yakir Aharonov, Ph.D., is professor of theoretical physics at Chapman University, where he holds the James J. Farley Professorship in Natural Philosophy. Considered one of the most highly regarded scientists in the world, Dr. Aharonov received the prestigious Wolf Prize in 1998 for his co-discovery of the Aharonov-Bohm Effect, one of the cornerstones of modern physics.
Dr. Aharonov's current research with Chapman University team members Menas Kafatos, Ph.D., Jeff Tollaksen, Ph.D. and participants from other universities includes a grant awarded from the Science and Transcendence Advanced Research Series (STAR) for a project titled "Subjective Experience as a Window on Foundational Physics." The aim of the project is to investigate the areas of tension between objective scientific description and human conscious experience.

Daniel Alpay
Professor, Mathematics
Dr. Alpay’s research interests are along five main directions, namely Schur analysis in the setting of slice-hyperholomorphic functions, infinite dimensional analysis and white noise space theory, linear systems and applications to wavelet filters and signal processing, functions of a bicomplex variable, and function theory on a compact Riemann surface. A number of the underlying projects are at the interface between mathematics, signal processing, and models for linear systems appearing in electrical engineering. The notions of positive definite function and of the associated reproducing kernel Hilbert space play an important role in these various directions of research.

Peter Jipsen, Ph.D.
Professor, Mathematics
Dr. Jipsen’s research is about the interplay between abstract algebra, logic and proof theory, concentrating mostly on ordered algebraic structures. He is particularly interested in residuated lattices, including basic logic algebras, MV-algebras, Heyting algebras, lattice-ordered groups and relation algebras, as well as (semi)lattices with operators and Boolean algebras with operators. He develops algorithms for enumerating finite models and uses automated theorem provers and model checkers for his research. His investigations include the design of concurrent algorithms for large-scale computational mathematics.
