The Computer Science and Electrical Engineering Department aims to maintain a program of excellence in teaching, research, and service for all of its programs. At the undergraduate level, we will provide students with a firm foundation of both the theory and practice of Computer Science and Computer Engineering. Our curricula also give students the social, ethical, and liberal education needed to make significant contributions to society. Students receiving a bachelor’s degree are ready to enter the work force as productive computer scientists or computer engineers, or to continue their education at the graduate or professional level.
At the graduate level, we are committed to developing the research and professional capabilities of students in Computer Science, Computer Engineering, Electrical Engineering and Cybersecurity. Our programs provide a deeper mastery of the basics of these fields, as well as opportunities to collaborate on leading-edge research with our faculty. Our faculty are engaged in both practical and theoretical research, often in partnership with government agencies, private industry and non-governmental organizations. The aim of this research is to advance knowledge within our disciplines and also to contribute to solving problems faced by our society.

Reinforcement Quantum Annealing: A Hybrid Quantum Learning Automata
(Nature Research, 2020-05-14)We introduce the notion of reinforcement quantum annealing (RQA) scheme in which an intelligent agent searches in the space of Hamiltonians and interacts with a quantum annealer that plays the stochastic environment role ... -
Independent vector analysis for common subspace analysis: Application to multi-subject fMRI data yields meaningful subgroups of schizophrenia
(Elsevier, 2020-04-28)The extraction of common and distinct biomedical signatures among different populations allows for a more detailed study of the group-specific as well as distinct information of different populations. A number of subspace ... -
Density of Modes for 2D finite photonic crystal structures
The density of modes for an open cavity constituted by a finite 2D photonic crystal is discussed. Modes depend on the cavity excitation and on the finite transverse and longitudinal confinement introduced by the finite sizes. -
Homogenization procedure for a metamaterial and local violation of the second principle of thermodynamics
(2008-08-07)Classical theory of crystals states that a medium to be considered homogeneous must satisfy the following requirements: a) the dimension of the elementary cell must be much smaller than the incident wavelength; b) the ... -
Energy exchange properties during second harmonic generation in finite photonic band gap structures
(IEEE, 2004-07-26)The principal goals in optics is to achieve the basic knowledge necessary to tailor the properties of light. The more intriguing uses of one-dimensional (1-D) PBG structures that have recently been suggested is their ... -
Non-phase-matched enhancement of second-harmonic generation in multilayer nonlinear structures with internal reflections
Traditional notions of second-harmonic generation rely on phase matching or quasi phase matching to achieve good conversion efficiencies. We present an entirely new concept for efficient second-harmonic generation that is ... -
Nonlinear Plasmonic Cloaks to Realize Giant All-Optical Scattering Switching
(American Physical Society (APS), 2012-06-27)Here we extend the reach of Fano resonant coupling by combining this concept with cloaking and plasmonic resonances in a single nonlinear nanoparticle, in order to realize giant all-optical scattering nanoswitches controlled ... -
Ultrashort Pulse Propagation in Negative Index Materials: From Negative Refraction to Nonlinear Pulse Propagation
