About me

Lang de


I like to apply and develop science to contribute to a conscious management of chemical compounds that we release to our environment. Further, I am convinced that it makes sense to use Open Source software in this context.

As an independent consultant, I do my best for my clients. In addition, I continue my work on free software for risk analysis of chemicals in the environment.
