[9] He was appointed the Dean of the Charles E. Schmidt College of Science at the Florida Atlantic University from 2017 to 2020,[10] since then he has been serving as the Bjorn Lamborn Endowed Chair in Astrophysics.

[11] From 2012 to 2016, Sarajedini served as the Associate Editor-in-Chief of The Astronomical Journal and held the position of chair for the NSF Program Review of the National Optical Infrared Laboratory and the Cycle 29 Hubble Space Telescope Time Allocation Committee in 2021.

[7] In addition to his research and editorial roles, Sarajedini has contributed to science communication as the Scientific Consultant of the PBS television series Star Gazers since 2018.

[2] Sarajedini conducted a series of joint studies to understand globular clusters and stellar populations as part of Hubble Space Telescope Treasury Projects.

Subsequently, he was a co-investigator on the Hubble Space Telescope program, GO-13297, employing UV/blue filters to enhance the characterization of multiple population patterns in Galactic Globular Clusters, shedding light on the details of their formation and the origin of their stellar generations,[14] while also offering insights into C, N, O abundance variations and helium enrichment in these stellar systems.

[22] Furthermore, as part of the Panchromatic Hubble Andromeda Treasury program, he investigated about one third of M31's star-forming disk, revealing substantial overdensities in the 10 kpc ring with ages over a billion years, challenging prior assumptions.
