Károly Héberger Ph.D., Cand. Sci., D.Sc., t.Prof.. in his early carrier he investigated liquid phase oxidation (radical) processes, and determined rate constants by kinetic ESR spectroscopy. Later he studied Quantitative - structure activity (property) relationships. QSAR, QSPR and QSRR. Now he deals with chemometrics: multivariate data evaluation techniques, principal component analysis, stepwise linear regression, partial least squares regression, variable selection, model building and validation, pattern recognition (supervised and unsupervised), classification of food products, clustering, method comparison and ranking, etc. His scientific results were presented in more than 160 papers (including book chapters) and more than 300 lectures (or posters). Hirsch index=34 and i-10=index 83 (Web of Sci). The papers were cited above 3500 times (without self - citations and cross - references).
