Our laboratory is a part of the Finnish Center of Excellence in Inverse Problems research, nominated by the Academy of Finland. We study various computational methods for combining modelling and measurements; an underlying 'practical' aim is to develop tools to analyze the reliability of model predictions. Parameter Estimation, Inverse Problems and Data Assimilation are somewhat overlapping concepts used in different scientific communities. Parameter estimation typically refers to the identification of a finite set of model parameters, while inverse problems often deal with the estimation of continuous profiles or functions. A prime example for data assimilation is weather prediction: online identification and prediction of the state of a large dynamical system. All the concepts are relevant to us. Especially, we focus on the following generic topics.
