My research interests are in the area of programming languages,
operating systems, object-oriented systems and distributed
computing, and more specifically in the region where they overlap
(such as language design for distributed Object-oriented
I'm currently involved in developing a new, very simple,
object-based language called Grace,
named after Rear
Admiral Grace Hopper. Grace is intended for teaching novice
computer scientists to program in the object-oriented style, but
is a full-featured language that can be used for almost any
purpose, including its own compiler. You can try out Grace on the
My favorite system for trying out ideas is Smalltalk. I have written a few Squeak goodies that I believe are generally useful. I have been actively working on Traits with the folks from SCG in Bern; see Nathanael Schärli's Traits page for details.
I'm a co-author of two books on Smalltalk programming, Squeak by Example,
and Pharo By Example.
My hobbies include cycling, cross-country skiing, hiking, mending houses.
