Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 20 Settembre in Aula Magna, Piazza Leonardo da Vinci, 42, dalle 17:30 alle 19:15 CET.

PhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento.

La speaker Laura Ceresa condurrà un seminario dal titolo “Formulation and probabilistic assessment of Diclofenac fate in a soilwater system under uncertainty”. 

Abstract:

Drinking water resources are threatened by several contaminants. Among these, Diclofenac (Dcf) poses major concerns due to its persistent and bioactive nature. Developing predictive tools to interpret its fate is then key to drive environmental protection actions. The modeling framework presented in this PhD talk is based on conceptualizing the molecular dynamics of Dcf biodegradation in a selected soil-water system. The geochemical model is subject to stochastic calibration through Acceptance-Rejection Sampling. The associated results fully embed uncertainty quantification and show that data scarcity and/or redundant model parametrization might deteriorate the quality of some parameter estimates. The issue is addressed by reducing the complexity of the model. The resulting formulations are framed within a multi-model context where the performance of each (re-calibrated) candidate model is assessed (in a relative sense) through the Kashyap identification criterion. The results suggest that an optimal trade-off in terms of model complexity (i.e., level of parametrization) given data availability can be assessed to satisfactorily interpret the system dynamics.

Al termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento.
