Phillip A. Laplante is Professor of Software and Systems Engineering and a member of the graduate faculty at The Pennsylvania State University. His research, teaching and consulting focuses on software quality particularly with respect to requirements, testing, and project management. Before joining Penn State he was a professor and senior academic administrator at other colleges and universities.
From 2010 through 2016 he was the founding chair of the Software Professional Engineer Licensure Committee for the National Council of Examiners of Engineers and Surveyors. This volunteer committee created, maintains and scores the exam used throughout the United States to license Professional Software Engineers.
Dr. Laplante has consulted to Fortune 500 companies, startup ventures, the U.S. Department of Defense, NASA and the National Institute for Standards and Technology (NIST). He is on the Board of Directors for a [...] million heavy infrastructure construction company and serves on various corporate technology advisory boards.

Mohamad Kassab is an associate research professor and a member of the graduate faculty at The Pennsylvania State University. He earned his Ph.D. and M.S. degrees in computer science from Concordia University in Montreal, Canada. Dr. Kassab was an affiliate assistant professor in the department of computer science and software engineering at Concordia University between 2010 and 2012 and a postdoctoral researcher in software engineering at École de Technologie Supérieure (ETS) in Montreal between 2011 and 2012, and a visiting scholar at Carnegie Mellon University (CMU) between 2014 and 2015.
Dr. Kassab has been conducting research projects jointly with the industry to develop formal and quantitative models to support the integration of quality requirements within software and systems development life cycles. The models are being further leveraged with the support of developed architectural frameworks and tools. His research interests also include bridging the gap between software engineering practices and disruptive technologies (e.g., IoT, blockchain). He has published extensively in software engineering books, journals, and conference proceedings. He is also a member of numerous professional societies and program committees, and the organizer of many software engineering workshops and conference sessions.
