Sponsored by NSF and NASA grants, I have been working at the DMLab in Georgia State University. In an interdisciplinary team of Computer Scientists and Solar Physicists, my research objective is to help provide insight into space weather activities through research-to-operation and operation-to-research efforts. Using machine learning and statistical tools, I focus on (1) data-driven pattern extraction, (2) prediction of occurrence of the solar events with sever impact on our infrastructure, and (3) follow-through on translating back the findings into the host domain, Solar Physics.

Due to the high-dimensionality and heterogeneity of data coming from an array of ground-based and space-borne observatories, a typical project in this area requires engineering of complete pipelines of data integration, preprocessing, curation, training, and evaluation. These are compute-intensive tasks that I carry out thanks to the in-house computing resources of the DMLab.
