PSRG People


Lance C. Pérez, PhD

After receiving his doctorate from the University of Notre Dame, Lance was a postdoctoral fellow with a joint appointment from the University of Notre Dame and the Swiss Federal Institute of Technology in Zurich, Switzerland. In 1995, he became a visiting assistant professor with the Division of Engineering at the University of Texas at San Antonio. He joined the faculty in the Department of Electrical Engineering at the University of Nebraska in 1996. He currently serves as associate vice chancellor for academic affairs in addition to his duties as a professor of electrical engineering. Although a bulk of his work is in channel coding, his work has expanded into wireless sensor networks, localization, assisted living technologies, and image processing — as well as interdisciplinary work in STEM education.

Eric Psota, PhD

Eric is currently an Assistant Research Professor at the University of Nebraska-Lincoln, where he also obtained his BSEE in 2004, MS in 2006, and PhD in 2010. His research interests include image processing, computer vision, machine learning, multi-view imaging, signal processing, communications, information theory, and channel coding. His specialties include designing, simulating, and implementing high-performance algorithms for both computer vision systems and channel coding. His hobbies include hiking, skiing, weight-lifting, and photography.

Presentación Rivera-Reyes, PhD

Presentación is currently a Postdoctoral Research Associate from Utah State University, where he obtained his PhD in Engineering Education. He received his BSEE and MBA at the National University in Honduras, his native country. He has experience in the telecommunication industry where he worked developing solutions of high-speed transmission systems for ISP's and mobile network operators. He has trained engineers and technicians through formal courses, on-the-job training, and supervising on field. His research interest includes self-regulated learning and troubleshooting problem solving. His long-term goals include improving laboratory hands-on activities based on how students improve their metacognitive skills. His hobby is aircraft modeling. His models are of plastic requiring assembly, gluing, and painting using airbrush, resin parts, photo edge, and aging techniques.

Graduate Students

Jay Carlson

Jay is from Lincoln, Nebraska and graduated from Lincoln Southeast High School in 2005 and the University of Nebraska-Lincoln in 2010 with a BSEE. He is primarily focused on applying his skills in hardware/embedded design to medical technologies. His research interests include technology integration for semi-autonomous robot surgery, assisted living technologies, and localization. Jay is also passionate about STEM education, both in early learning scenarios and inside the engineering classroom. Outside of engineering, Jay enjoys cooking, mixology, home repair and remodeling, design, and photography. He is an avid jazz piano player (always wishing he had more time to play).

Mateusz Mittek

Mateusz was born in Wrocław and studied at Politechnika Wrocławska. Outside of academia, he enjoys all things motorcycle, and was the Polish national vice champion in Gymkhana, a technical riding motorsport.

Yanfeng Liu

Yanfeng Liu was born and raised in China. He is currently a second year master student at UNL, pursuing his degree in Electrical Engineering. Yanfeng is interested in computer vision and deep learning. He has worked on multiple research projects in the lab, such as gaze tracking, fiducial marker classification, instance level segmentation, pixel embeddings, etc.

Former Students

Jędrzej Kowalczuk, PhD

Jędrzej received his BS and MS degrees in 2007, both in computer science, from the Technical University of Szczecin, Poland. He graduated from the University of Nebraska-Lincoln with his PhD in 2015. His research interests include multi-view computer vision, image processing, and high-performance computing. He currently works at Microsoft HoloLens in Seattle.
