Research Statement

Dr. Abdelrahman main research interests are data mining, visual analytics, multi-agent, information retrieval, and information extraction using natural language processing and ontologies. His current research is directed to conduct advanced big data analytics and modeling to devise computational algorithms and frameworks for biomedical computing. These solutions primarily tackle clinical data analytics problems such as temporal behaviors, data heterogeneity (structured and free-text), missing data, imbalance, and sparseness.  His research lab conducts intelligent computing projects of (1) data analytics for biomedical computing, and (2) computational algorithms for real-life applications.
