Research Interests

Calton's research interests are in the areas of service computing, distributed and cloud computing, dynamic analytics on changing big data. His current projects include cloud computing (WISE/Elba project) and dynamic analytics (GRAIT-DM project) research. Using experimental data from realistic benchmarks, the WISE project studies millibottlenecks, very short bottleneck phenomena that have large impact on n-tier application latency. The GRAIT-DM project continuously collect fake news on COVID-19 and other disasters to distinguish real information from fake news. The sponsors for Calton's research include both government funding agencies such as NSF, and companies from industry such as Fujitsu.  He is the director of Center for Experimental Research in Computer Systems (CERCS) at Georgia Tech.  He is also the director of RCN on Big Data for Smart Cities, managed as part of the GRAIT-DM project. Positions available: Georgia Tech is recruiting good graduate students.
