Being a theoretical astrophysicist, I enjoy doing some
but often have to do
or
.All those are fun!
I also think about my colleagues' observations, for instance those
by Sally Heap's STIS/HST team.
Yes, it's the disk of Beta Pictoris. Beautiful, isn't it?
I study the birth and evolution of binary stars and planetary systems, dynamics of astrophysical disks, physics of circumstellar dust, with occasional diversions to binary black holes and AGNs. I was leading a group studying theory of planetary pystems in Stockholm. I co-edited the journal Planetary and Space Science. An International Evaluation of Swedish Astronomy and Astrophysics (Oct. 2000) summarized the areas of my research program and evaluated it. I was the most cited astronomer in Stockholm (1994-2004).
I am a tenured professor at the
University of
Toronto. I split my time between the
Dept of Astronomy and Astrophysics at the
St. George (downtown) campus, and
Department of Physical and Envir. Sciences of
UTSC (U of T at Scarborough).
I usually teach on Mo and Thu at UTSC, and on Fridays at DAA.
