Johan Eker's Homepage
After graduating in 1999 under the supervision of Karl-Erik Årzén and Karl Johan Åström, I did my post doc in the Ptolemy group at UC Berkeley. My interest lie in real-time control and software design for embedded systems. I am active in the Caltrop group working on the design of the Cal actor language, which has an excellent homepage http://www.gigascale.org/caltrop.
