Dr. Aldo Morales has been a faculty member at Penn State Harrisburg (PSH) since August 2001 and is currently a professor of the Electrical Engineering and Electrical Engineering Technology programs. Prior to joining PSH, he taught at Penn State DuBois. In addition, he was a Teaching Assistant and then Research Assistant at the State University of New York at Buffalo (SUNY-Buffalo)

Dr. Morales co-founded the Center for Signal Integrity at Penn State Harrisburg. Under his leadership, he obtained funds from the Ben Franklin Technology Partners of Pennsylvania in the amount of $800K, augmented later by another $200K from Center member companies. Companies that belong to the center are: FCI, Samtec, Phoenix Contact, Berk-Tek, Souriau and others. He also works closely with Agilent technologies. Dr. Morales recently obtained a prestigious Major Research Instrumentation (MRI) grant from the National Science Foundation (NSF) in the amount of $448K to further support research activities in the Center for Signal Integrity.

Dr. Morales has been honored for his technical achievements. For example, by the 2007 International Conference on Consumer Electronics, Las Vegas, Nevada with the best poster award for the paper “Transmitter Pre-emphasis and Adaptive Receiver Equalization for Duobinary Signaling in Backplane Channels.” In addition, by IEEE-Asia Pacific Conference on Circuits and Systems in 1996, for his paper “Basis Matrix Representation of Morphological Filters with N-Dimensional Structuring Elements.” He was also finalist in DesignCon 13, Santa Clara for his paper “A Rapid Prototyping of FPGA-Based Duobinary Transmitter/Receiver for High Speed Electrical Backplane Transmission.” In addition, he was honored by the Central Pennsylvania Engineers Week Council with the Technical Achievement Award 2009. Dr. Morales is also active in getting grants to support the educational enterprise. He obtained $600K, as Co-PI, from the National Science Foundation (NSF), to encourage women and minority students to enroll in Science, Technology, Engineering and Mathematics (STEM) degrees at Penn State. Dr. Morales is also involved coordinating local high school robotics competitions. Dr. Morales was honored twice by Penn State: Educator of the Year (1998) and Penn State Engineering Society’s Outstanding Teaching Award (1999).

Dr. Morales organized (or co-organized) several international conferences. He was the Technical Chair, General Chair, 2009 and 2010, respectively for the International Conference in Consumer Electronics, which is co-sponsored by the IEEE and Consumer Electronics Association (CEA). He was also the Co-Chair of the 2012 International Symposium on Consumer Electronics, Harrisburg, Pennsylvania. He was featured in Penn State’s Outreach Magazine, indicating that Dr. Morales “provides the community and regional industries with opportunities to expand their skills in the electrical engineering field.”
