Who is Hosein?

I am a Ph.D. candidate with an interest in galaxy formation and evolution. My research looks at the formation and growth of the mass of the Universe in the form of stars. I explore the stellar mass budget of galaxies by morphological types (See the figures below). My in-depth study of galaxies also involves decomposing galaxies into their building blocks. By structural decomposition of galaxies, I further study the formation and evolution of bulges and disks in the Universe. This study allows us to give insight into the history of galaxies and the pathways they have gone through to become eventually gorgeous systems we observe today.

Overall, very similar to Milky Way, disks contain gas, dust, young, and old stars, open clusters. Stars in the disk orbit in approximately circular orbits. The bulge contains older stars, orbits much more random. The halo contains the oldest stars and globular clusters, orbiting completely random. Most galaxies seem to have black holes in their centers, disk, bulge, nucleus, halo, and globular clusters.

Other Activities

I am very active out of my office, too.

I am the founder and president of the DASTAN Foundation. The Foundation is a Non-for-Profit organization registered in Australia (ABN 34 789 627 512), established for charitable purposes aimed at enhancing science and education in developing countries. DASTAN supports excellence and innovation in research, with a particular emphasis on environmental science, and renewable energies. Please see DASTAN’s website for more info and to join this movement.  (https://www.dastanfoundation.com)

I also run a free crowdfunding website, UChangeIt, for charitable purposes (https://www.uchangeit.com).


You are more than welcome to contact me, for more info about me, my research, or any of my other activities.
