• Our group works since 2009 in multidisciplinary research field. Giving a prominent investigation on the: a) Application of design of experiments (DOE) on chemistry data; b) Application of multivariate calibration methods in first and second order data; c) Employment of variable and sample selection methods in analytical data; d) Employment of image processing techniques for chemical purposes. The investigation spreads the application of chemometrics in many fields of analytical chemistry such as electrochemistry, spectroscopic, and separation methods as well as others chemistry areas. The works and the investigations developed in this group have been sensed on the activities of teaching, research and scientific production of the Chemistry Post-Graduate Program (PPGQ-UFRN) and on the Institute of Chemistry. And accessed the investigations of other researchers at UFRN. In 2013 the present group have been integrated a new philosophy based on biological chemistry which it was called “Biological Chemistry and Chemometrics”.
