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.

Learning to regularize with a variational autoencoder for hydrologic inverse analysis
(2019-06-06)Inverse problems often involve matching observational data using a physical model that takes a large number of parameters as input. These problems tend to be under-constrained and require regularization to impose additional ... -
PPT : New Low Complexity Deterministic Primality Tests Leveraging Explicit and Implicit Non-Residues
(2019-08-20)In this set of three companion manuscripts/articles, we unveil our new results on primality testing and reveal new primality testing algorithms enabled by those results. The results have been classified (and referred to) ... -
KiloGrams: Very Large N-Grams for Malware Classification
(2019-08-01)N-grams have been a common tool for information retrieval and machine learning applications for decades. In nearly all previous works, only a few values of n are tested, with n>6 being exceedingly rare. Larger values of n ... -
Picturing Bivariate Separable-Features for Univariate Vector Magnitudes in Large-Magnitude-Range Quantum Physics Data
(2019-05-06)We present study results from two experiments to empirically validate that separable bivariate pairs for univariate representations of large-magnitude-range vectors are more efficient than integral pairs. The first ... -
Moving to client-side hashing for online authentication
Credential leaks still happen with regular frequency, and show evidence that, despite decades of warnings, password hashing is still not correctly implemented in practice. The common practice today, inherited from previous ... -

Soliton Frequency Combs in Dual Microresonators
(Optical Society of America, 2019-09-15)We study soliton frequency combs generated in dual microresonators with different group velocity dispersion. We obtain stable bright and dark solitons at different pump amplitudes. -
Third-Order Nonlinear Optical Properties of ALD Grown TiO2 Thin Films
(Optical Society of America, 2019-09-15)Nonlinear index values as high as 1±.1x10-9 cm2/W were measured of ALD based TiO2 films. The 1000-fold increase in the index is believed to be due to the incorporation of nitrogen during growth. -
Dissipative cnoidal waves (Turing rolls) and the soliton limit in microring resonators
