Anuj Karpatne, an assistant professor of computer science and a Discovery Analytics Center faculty member, has been named the 2019 Intelligent Systems and Geoscience (IS-GEO) inaugural Fellow.

The announcement was made by Suzanne Pierce, a research scientist at the Texas Advanced Computing Center (TACC) and principal investigator for the IS-GEO Research Coordination Network, during the American Association for the Advancement of Science (AAAS) conference in Washington, D.C., today.

“I am pleased to announce the IS-GEO Fellows Program,” Pierce said. “The program is designed to support researchers as they commit to in-depth projects to accelerate discoveries. Dr. Karpatne was selected because of his expertise in scientific theory{or physics}-guided machine learning. Throughout his fellowship year, he will evaluate applied machine learning approaches to Earth datasets for the energy industry.”

DAC Student Spotlight: Joseph Weissman

Joseph Weissman, DAC master’s student in statistics

Joseph Weissman graduated from Virginia Tech in May 2018 with triple majors — mathematics, physics, and Computational Modeling and Data Analytics (CMDA).

“I really gravitated toward the machine learning side of my CMDA classes,” Weissman said. “And because I wanted to learn more about networks, I took Dr. Sengupta’s class on the subject during my last semester.”

His final project for the class evolved into the research project he is now working on as a master’s student at the Discovery Analytics Center, where he is advised by Srijan Sengupta.

Professor will use new machine learning techniques to decrease deaths resulting from traumatic brain injury

Chandan Reddy (left) is an associate professor in the Department of Computer Science and faculty at the Discovery Analytics Center.

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.
