My research interests are magnetic field processes in space physics and astrophysics, particularly how magnetic field affect the interstellar medium, disks around young stars, solar, stellar winds, jets and the early universe. I am using sophisticated state-of-the-art numerical modeling as experiments in conjunction with new theoretical approaches and observational data. 

I am also interested in developing new computational models (such
as coupling Kinetic-MHD models; PIC Codes-MHD; new AMR techniques, etc).

Voyager 1 and 2, the most distant man-made objects are right now probing the confines of the solar system. It is believed that Voyager 1 in December 15, 2004 has exited the Termination Shock, the first boundary of the solar system, and now is going through the turbulent region the Heliosheath where magnetic effects are crucial. Voyager 2 in the August of 2007 crossed the shock going southward from Voyager 1.

Recently we predicted that the heliosphere is asymmetric and were able to match the Voyager 1 and 2 particle observations. By matching the radio data and particle we are able to find the plane of the interstellar magnetic field plane.
