She has had various professional experiences that have inspired her particular interest in portraits as photographic, journalistic reports. She has shown various works in Switzerland and Germany, where she won the prestigious national prize for young photographers, ““Deutscher Jugendfotopreis de 2012,” with her final student project. Her experience of having been born in Switzerland, home of the Alps, and its particular context created within her a profound closeness to nature and a need to seek out rural areas, urges that also form a fundamental part of her photography. Tjefa showed a series of photographs documenting women in the Chimalapas in Centro Hemisférico in 2012.
