The existence of dark matter is one of the Universes great mysteries. All stars, planets, and interstellar gas are made from atoms, and yet atomic matter represents only 15% of the total matter in the Universe. The remaining 85% is dark matter. Dark matter provides the cosmic foundation for galaxies to form, but its microphysical properties remain unknown. Dr. Tulin's research provides new directions toward discovering dark matters elusive particle nature. By combining astrophysical measurements from dwarf galaxies to galaxy clusters, he is developing new ideas to illuminate dark matters particle dynamics through its effect on cosmic structure.
