Ciska de Greef (she/her) - Chair
Ciska de Greef is the chair of GEWIS. As a chair she is ultimately responsible for everything that happens within the association and is therefore also the first point of contact of the association, which makes her the face of the association. Hence, she often has contact with the departmental board and the building management. Luckily she does not have to do this all by herself since she has a whole board with whom she has to take this on together. She is responsible for the structure within the board and the association. She leads the General Members Meetings (GMM) and the Board Meetings (BM); a weekly meeting of the board in which the mail, budgets, committees, fraternities and policies are discussed. Furthermore, she attends the meetings of the FSE (niece associations) and the WISO (sister associations).
