Demetri Psaltis (Greek: Δημήτρης Ψάλτης) is a Greek-American electrical engineer and the Dean of the School of Engineering at École Polytechnique Fédérale de Lausanne since 2007.[1] He is also a Professor in Bioengineering and Director of the Optics Laboratory of the EPFL.[2] He is one of the founders of the term and the field of optofluidics.[3] He is also well known for his past work in holography, especially with regards to optical computing, holographic data storage, and neural networks. He is an author of over 350 publications, contributed more than 20 book chapters, invented more than 50 patents, and currently has a h-index of 80.


Demetri Psaltis received his B.S. (1974), M.S. (1975), and Ph.D. (1977) at Carnegie Mellon University.

Academic career[edit]

From 1980 to 2007, he worked at Caltech as an Assistant Professor (1980–1985), Associate Professor (1985–1990), Full Professor (1990–1996), Executive Officer for Computation and Neural Systems (1992–1996), Director for the National Science Foundation Center for Neuromorphic Systems Engineering (1996–1999), Thomas G. Myers Professor (1996–2007) and Director for the DARPA Center for Optofluidic Integration (2004–2007). In 2007, he moved to Switzerland as a Professor and Dean of the School of Engineering at EPFL.

His current research focuses on optofluidics[4][5][6] and nonlinear optics particularly in scattering media.[7]

His past research had focused on optical computing,[8] holographic data storage,[9] and neural networks.[10]
