The lab has a general open-door policy. This does not mean that we are open 24/7, but it means that you are welcome to walk in, enjoy a coffee, attend a class as a visitor, or just check if there is a free spot to work on something – during the opening times . The below calendar features the time you will most probably meet someone. While every effort is made to keep the calendar as up-to-date as possible, absolute accuracy cannot be guaranteed.
