To help physicians decrease the number of deaths resulting from traumatic brain injuries, Chandan Reddy, associate professor in the Department of Computer Science and faculty at the Discovery Analytics Center,  will use new machine learning techniques for computational models to predict short- and long-term outcomes, categorize traumatic brain injury patients, and provide interventions tailored to a specific patient and his or her injury. This four-year study is funded by a National Science Foundation grant in excess of $1 million. Click here too read more about the grant.

Gloria Kang and Huthaifa Ashqar recently earned doctorates from Virginia Tech in totally different fields, but they have something in common — cross-disciplinary training to solve today’s tough urban challenges.

Kang and Ashqar are the first graduates of the National Science Foundation-sponsored urban computing certificate program. Both are planning to walk at the December commencement ceremony in Blacksburg.

Administered through the Discovery Analytics Center, the program trains students across disciplines in the latest methods in analyzing massive datasets to study key issues concerning urban populations.  Click here to read more about Gloria and Huthaifa.

Virginia Tech study identifies recurring elements in conspiracy theories to learn what people who propagate them are thinking

Tanushree Mitra, DAC faculty member and assistant professor of computer science

What do online conspiracy theorists discuss; what are the recurring elements in these conversations; and what do they tell us about the way people think?

As Tanushree Mitra, assistant professor of computer science and a faculty member at the Discovery Analytics Center, and Mattia Samory, a post doc in the Department of Computer Science, set out to find answers, they turned to Reddit, a social media platform of thousands of smaller communities or “subreddits” connecting users with similar interests.

DAC Student Spotlight: Chen Gao

Chen Gao, DAC Ph.D. student in electrical and computer engineering

Chen Gao traveled to Newcastle, United Kingdom, last month to present a paper on human-object interaction at the 29th British Machine Vision Conference, a major international conference on computer vision and related areas held in the UK.

Gao is a first-year Ph.D. student in the Bradley Department of Electrical and Computer Engineering. After graduating with a master’s degree in electrical and computer engineering from the University of Michigan Ann Arbor in April 2017, Gao came to Virginia Tech as a visiting research assistant to work with Jia-Bin Huang. It was this experience that sparked his interest in the university’s Ph.D. program. Huang, a faculty member at the Discovery Analytics Center, is now his advisor.
