Computer Science Colloquia

Title: When Disaster Strikes: Supplementing Centralized Infrastructure with Opportunistic Communication
Speaker: Corey Baker
Affiliation: University of California, San Diego
Time: 4:00-5:00PM, Thursday, March 23, 2017
Location: Theater – Davis Marksbury Building

Abstract: Reliance on Internet connectivity is detrimental where modern networking technology is lacking, power outages are frequent, or network connectivity is sparse or non-existent
(i.e., developing countries, natural disasters, and in-field military scenarios). Realization of the limitations resulting from reliance on Internet and cellular connectivity were
prevalent in Hurricane Matthew (2016), which killed over 1000 people and destroyed cellular infrastructure. As an alternative, deploying resilient networking technology can facilitate the flow of information in resource-deprived environments to disseminate life saving data. In addition, leveraging opportunistic communication can supplement cellular networks to assist with keeping communication channels open during high-use and extreme situations. This talk will discuss the progress of a research platform and middleware that enables opportunistic communication and in vivo evaluation of delay tolerant routing schemes when the Internet is interrupted or unavailable by leveraging node relationships to create a delay tolerant social network. The solutions discussed in this talk further include applications related to IoT, mobile healthcare, and smart city
environments.

Biography: Corey Baker, Ph.D., is a University of California President’s Postdoctoral Fellow in the Electrical and Computer Engineering Department at the University of California, San Diego and is mentored by Professor Ramesh Rao. Dr. Baker’s research interests are in the area of cyber physical systems specializing in opportunistic wireless communication for the Internet of Things (IoT), smart cities, smart homes, and mobile health environments. Particularly, Dr. Baker is interested in pragmatic applications and the fundamental issues related to real-world resource availability in today’s operating systems for opportunistic wireless communication. Dr. Baker was a recipient of the GEM Ph.D Fellowship, Intel Scholarship, McKnight Dissertation Fellowship, and the NSF LSAMP Bridge to the Doctorate Fellowship. He received a B.S. degree in Computer Engineering from San Jose State University, a M.S. in Electrical and Computer Engineering from California State University, Los Angeles, and M.S. and Ph.D. degrees in Electrical and Computer Engineering from the University of Florida where he was advised by Professor Janise McNair. Corey has served on the board of directors of the National Society of Black Engineers (NSBE) numerous times as a two term National Treasurer and CFO, two term National Treasurer Emeritus, and as the Region 6 Chairperson. Dr. Baker is currently the NSBE Region 6 Finance Zone Advisor. Formerly, Dr. Baker was the official blogger for GEM and blogged about topics to promote success amongst STEM graduate students which included securing graduate school funding, navigating Ph.D. programs, and publishing.

Title: Enabling Expression-Driven and Expression-Aware Systems
Speaker: Mary Pietrowicz
Affiliation: University of Illinois
Time: 4:00-5:00PM, Thursday, March 27, 2017
Location: Theater – Davis Marksbury Building

Abstract: Human expression is at the heart of communication and creativity. It speaks through our spoken and written language, paralingual expression, physical gesture, and creative output. Typical investigations into models of human expression tend to focus on low-level signal processing features and fail to consider human perception. The resulting machine models are frequently out of alignment with what humans perceive and do, and therefore fail to support generalized application development.

In this  talk, I will introduce and demonstrate a process for developing machine models of human expression which are aligned with perception. I will also show how this process can reveal different dimensions of expressivity organically without requiring use of either predefined vocabulary or mapping onto predefined axes, which is commonly done when mapping emotion onto affect and arousal. This process enables the discovery of relationships among sub-dimensional expressive elements, that can then be used to improve the resulting machine models.

I will present some samples of expression-aware projects which either mirror human expression or extend the range of natural human expressivity. I will conclude by discussing the promise of leveraging models of human expression in the development of expression-driven applications for health and wellness.
 
Biography: Mary Pietrowicz is a Computer Science PhD candidate at the University of Illinois working with Professors Karrie Karahalios and Mark Hasegawa-Johnson. Her research focuses on human expression, and spans topics across human-computer interfaces, signal processing, machine learning, crowdsourced creativity, visualization, music, and interactive art. Prior to returning to study for her PhD, Mary was an engineer and researcher for a number of years in industry and academia, most recently at the National Center for Supercomputing Applications and the Pervasive Technology Labs at Indiana University.
