Areas of supervision
Soft computing and uncertainty modelling, data science, big data management and analytics, data mining and machine learning, computational statistics
I am interested in the following research areas where I tackle various themes strongly related to both Soft Computing and Data Science, in particular to: Uncertain Knowledge Bases and Databases with Imperfect Information (Imperfect Information Integration; Rule based Reasoning under Uncertainty, Incompleteness and Inconsistency in the context of Multivalued Logics; Query Optimisation for Efficient Imperfect Information Retrieval), Knowledge Discovery in Databases, Data Mining and Statistical Computing (Clustering/ Segmentation, Feature Selection, Classification Techniques, Statistical Techniques in Data Mining: Mixture Models and Probability Distribution Forecasting, and formerly in Statistical Databases). I am also interested in Algorithms and Complexity.
My interdisciplinary research interests concern various problems and applications particularly involving Data Science and related technologies. This work intertwines an academic expertise in Data Mining & Machine Learning, Statistical Modeling & Computational Statistics, Databases and Big Data Management and Analytics, and a practical and technical expertise in the major analytics technologies based on IBM SPSS Modeler & Statistics, SAS Enterprise Miner, R, RapidMiner, Weka, Hadoop and Big Data. Currently I have particular interests in bioinformatics and statistical data mining applications regarding knowledge and pattern discovery in classification, clustering and prediction problems involving genetic and phenotype data. Current interests concern also Digital and Statistical Research Methods in Social Sciences, Text and Web Mining in Sentiment Analysis, and Business Intelligence applications.
