Once every week while school is in session, EECS invites a distinguished researcher or practitioner in a computer science or electrical and computer engineering-related field to present their ideas and/or work. Talks are generally targeted to electrical engineering and computer science graduate students. This colloquium series is free and open to everyone.

Upcoming Colloquia

Software development, money, and you

Monday, September 25, 2017 - 4:00pm to 4:50pm
LPSC 125

How do software development skills relate to expected earnings? This colloquium will present recent research investigating how the answer to that question varies for different people in different contexts at different stages of different career paths. Come prepared to think about how your choices, your courses, and your activities at Oregon State University might affect your future after you graduate.

Speaker Bio

Christopher Scaffidi earned a Ph.D. in software engineering from Carnegie Mellon University, an M.S.E. in software engineering from Carnegie Mellon University, a M.S. in physics from Princeton University, and a B.S. in mathematics and physics from the University of Wisconsin in Madison. He began his career as a researcher in physics at Princeton University, then moved into professional software engineering during the dot-com boom. After seven years of web application development and consulting experience, he began his academic career as a software engineering researcher.


He is currently an associate professor of computer science in the School of EECS at Oregon State University. His research interests are where human-computer interaction and software engineering intersect. Most of his current projects aim to help software users to create code for themselves, and to effectively share that code with one another.


He recently served as director of the EUSES Consortium, an international association of seven universities and one company. He was co-chair for the Poster/Work-in-progress track at the 2009 International Symposium on End-User Development and is on the program committee for the 2010 ACM SIGCHI Symposium on Engineering Interactive Computing Systems. He has been a member of the program committee for the IEEE Symposium on Visual Languages and Human-Centric Computing since 2010. He is a member of the ACM and IEEE.

Sensors for Closed-loop Health Management

Monday, October 2, 2017 - 4:00pm to 4:50pm
LPSC 125

Electrical Engineering Department, University of Texas - Arlington


Mobile technologies have changed our life style significantly. Personalized tools such as wearable and implantable devices through wireless communication and Internet of Things have been utilized in healthcare to provide unique functions and reduce costs. Individuals can be empowered with tailored solutions without limitation in mobility or daily activities. Quantitative documentation of physiological parameters presents more accurate assessment. Direct stimulation on tissues or organs by electrical signals can restore or improve body functions. Continuous monitoring and adaptive administration of therapy to treat symptoms via wireless body networking can adaptively optimize the closed-loop health management.


This presentation discusses the development of wireless micro devices and integrated systems for clinical applications. The systems are based on batteryless, wireless implants with enhancement in miniaturization and functionalization. Miniaturization owing to flexible substrates and the elimination of bulky batteries allows endoscopic or minimally invasive procedures to deploy the implants without painful surgeries. Several diagnosis and therapeutic treatment examples for management of gastric and neural disorders, particularly as closed-loop systems, will be introduced. These examples aim to inspire new system application ideas to address the implementation and cost challenges in healthcare, and enable integration of electronics and medicines to improve human welfare and assist better living.

Human Allied Artificial Intelligence

Statistical Relational Learning (SRL) Models combine the powerful formalisms of probability theory and first-order logic to handle uncertainty in large, complex problems. While they provide a very effective representation paradigm due to their succinctness and parameter sharing, efficient learning is a significant problem in these models. First, I will discuss state-of-the-art learning method based on boosting that is representation independent. Our results demonstrate that learning multiple weak models can lead to a dramatic improvement in accuracy and efficiency.

One of the key attractive properties of SRL models is that they use a rich representation for modeling the domain that potentially allows for seam-less human interaction. However, in current SRL research, the human is restricted to either being a mere labeler or being an oracle who provides the entire  model. I will present our recent work that allows for more reasonable human interaction where the human input is taken as “advice” and the learning algorithm combines this advice with data. Finally, I will discuss our work on soliciting advice from humans as needed that allows for seamless interactions with the human expert.
