Research Interests

Calton's research interests are in the areas of service computing, distributed and cloud computing, integration and veracity of big data. His current projects include cloud computing (WISE/Elba project) and big data (GRAIT-DM project) research. Using experimental data from realistic benchmarks, the WISE project studies the interesting phenomena such as very short bottlenecks that have large impact on n-tier system response time. The GRAIT-DM project collects real world data from social sensors (e.g., Twitter and Facebook) and authoritative sources (e.g., CNN.COM and CDC for COVID-19 information) to detect physical events and manage real-time information on them. The sponsors for Calton's research include both government funding agencies such as NSF, and companies from industry such as HP, Fujitsu, and IBM.  He is the director of Center for Experimental Research in Computer Systems (CERCS), and affiliate faculty of Institute for Information Security and Privacy (IISP) 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.

Past projects:


Calton has taught several courses in the areas of systems and databases. In fall, he is teaching CS4220/6235 Real-Time Embedded Systems In spring, he is teaching CS4365/6365 Introduction to Enterprise Computing. Due to adaptation to the COVID-19 pandemic, the information on the courses have changed significantly. Please see the official information on Oscar and Canvas.
