She retired from competitive rowing after the1980 Summer Olympics and from September 1980, she worked as a rowing coach inPotsdam. She graduated with a diploma in physical education from theDeutsche Hochschule für Körperkultur (DHfK) inLeipzig in 1981. She later became thesculls trainer for the national women's team. She was thus responsible for preparing the sculls team for the1996 Summer Olympics inAtlanta, USA. Classification earlier in the year determined thatKathrin Boron was the strongest sculler, followed byJana Thieme,Katrin Rutschow, andKerstin Köppen. Guided by the principle that the strongest sculler should row in the singles, her preference was for Boron, but Boron preferred to row in the double or quad. Lau thus nominated Thieme for the single, Koppen and Boron would make the double, and Koppen, Boron, Rutschow andJana Sorgers were to make up the quad. Dr Ralf Kollmann, who as sports director was responsible for nominating the teams, rejected these teams and wanted rowers picked so that more clubs were represented. Germany's national rowing organisation (Deutscher Ruderverband) nominatedMeike Evers for the single, and Thieme andManuela Lutze, and for the quad the team recommended by Lau. Evers had come eighth or ninth in Lau's classification, and Lau predicted that Evers would not reach the A-final (she only made the C-final). Lau further predicted that the double would at best come fourth (they came fifth). Her final prediction was that the quad would win gold, which they did. By Lau's best assessment, had her suggested teams been accepted, all three boats would probably have won medals. After the Atlanta Olympics, she accused Kollmann of incompetence.[4]
