The people at PSI
Where analysis meets flavours
Some see brewing as an art, others as a science – Luc Van Loon combines both these virtues at his brewery. With the nose of a sommelier and the precision of a chemist, the former PSI researcher creates world-class beers.
Engineering skill and perseverance
Credit for the on-time completion of the major SLS 2.0 upgrade project is due in part to a team of dedicated electrical engineers.
PSI’s cement whisperer
John Provis has dedicated his research career to a building material that is far more exciting than you might think.
