The author, Matthias Gruber, is a professional researcher, specialized in biomedical informatics and artificial intelligence.
He is studying Wing Chun (Yip Man 葉問 lineage) since 1991, mainly with Grandmaster Keith-R. Kernspecht's European WingTsun® Organization (EWTO). His Sifu is Master Mario Janisch, 6th level practitioner.
In Wing Chun, intensive private training is the most efficient way to progress. Furthermore, it is better to learn from more than just one source. For this reason the author only teaches a handful of students privately and focusses his own training accordingly.
