- Numerical analysis of spectral problems (Pokrzywa, Regińska)
- Numerical analysis of methods for solving partial differential equations (Wakulicz, Deriaz)
- Applications of wavelets to problems of numerical analysis (Deriaz, Pokrzywa, Regińska, Wakulicz)
- Discrete ill-posed problems (Regińska)
- Inverse problems for partial differential equation and regularization methods (Regińska, Wakulicz, Deriaz)

A seminar organized by the Laboratory covers a wide scope of numerics and attracts attention of mathematicians from other institutes.

The laboratory also organized at the Banach Center mini-schools, directed especially towards young researchers: Regularization methods for ill-posed problems of analysis and statistics – lectures of S. Pereverzyev, (15-25 May 2007); Course on inverse and ill-posed problems – lectures of Andreas Neubauer (26-29 March 2008).
