In 1996 Danusia founded DSz Associates, which became Test Kitchens in 1999. Before that, Danusia built several market research departments and spent six years working with multinational companies to develop and introduce innovative technologies in Asia, Africa and Latin America. Her work overseas focused on field research to discover the motivating factors behind use / non-use of various products and services.

While overseas, Danusia realized that making people feel comfortable during research is key to getting insights that go beneath the surface. Ask her about focus groups under the baobab tree in Kenya or the one-on-one interviews in teashops in some of Bangkok's more interesting districts.

Danusia is a member of the Qualitative Research Consultants Association and the Usability Professionals Association.
