As a theoretical physicist/astrophysicist, I enjoy theory   but often resort to numerics like or .

All those are fun! I also think about my colleagues observations, for instance those by HST of
     the beautiful disk of Beta Pictoris.

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, AGNs and aerodynamics of airplanes. I was leading a group studying theory of planetary systems in Stockholm. I have 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).

Since 2005 I am a tenured full professor of Physics and Astrophysics 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 Env. Sciences of UTSC (U of T at Scarborough), where in 2016 I have designed and built supercomputers based on CPU, GPU and IXP (Intel Xeon Phi) processors.

I use my knowledge of aviation, aerodynamics and physics to study the 2010 airplane catastrophe in Smolensk, Russia, in which 96 persons including the Polish president perished. As an independent investigator, I have aided governmental and parliamentary committees in Poland to explain the details of the crash to the public.

I mountainbike, fly (FAA & TC PPL) and dive (PADI Advanced Open Water Diver).
