Geir-Arne Fuglstad

Om

Professor i statistikk ved Institutt for matematiske fag og leder for studieretningsutvalget for Industriell matematikk ved studieprogrammet Fysikk og matematikk.

Forskning

Mine hovedinteresser er stokastisk modellering i rom-tid og beregningsorientert statistikk. Spesielt bruk av rom-tid modeller beskrevet av stokastiske partielle differensialligninger som gir veldig effektive beregninger. Jeg er interessert i anvendelser i et bredt spekter av vitenskapelig områder fra epidemiologi og demografi til geografi.

IMod: Partial differential equations, statistics and data: An interdisciplinary approach to data-based modelling

Inter-disciplinary project building collaboration between statistics, partial differential equations, numerics, neuroscience, and fluid mechanics.

MASCOT: Maritime Autonomous Sampling and Control

Inter-disciplinary project that aims to develop and designxa0observational strategies in spatio-temporal domains, enabling autonomous platforms to increase our knowledge of dynamic environments like the upper water-column.
