Differential equations (deterministic or stochastic) play a fundamental role in modelling dynamic phenomena in fields as diverse as physics, biology, finance, engineering, chemistry, biochemistry, neuroscience, ecology, meteorology, pharmacology and others. Models defined via differential equations (or systems of differential equations) usually depend on finite- or possibly infinite-dimensional parameters. In order to obtain a model that is useful in practice, it is critical to know these parameters, or to estimate them in case they are unknown. The workshop aims at providing a meeting place for researchers and practitioners in the area of parameter estimation for deterministic and stochastic differential equations, who will review different methods used to tackle the problems arising in these fields, assess the achieved progress, and identify future research directions.
