Jah has authored a number of academic papers, including Entropy-based approach for uncertainty propagation of nonlinear dynamical systems.

[15] In 2006, Jah left NASA JPL and became a Senior Scientist at Oceanit Laboratories on Maui, which involved using optical data to determine space trajectories.

[17] He directed the AFRL Advanced Sciences and Technology Research Institute for Astronautics (ASTRIA) in Maui from 2007 to 2010 and then at Kirtland Air Force Base in New Mexico until 2014.

[20] At Kirtland Air Force Base, Jah was mission lead in Space Situational Awareness and advised the satellite guidance and control program.

[24][25] He gave formal congressional testimony to the Federal government of the United States in 2017, discussing a Civil Space Traffic Management system.

[26] He stated that he believes that the USSC should create a global, accessible, and transparent space traffic management system, which would protect spacecraft from debris and a lack of monitoring.

[30][31][32][33][34][35] At The University of Texas at Austin, Jah is a Distinguished Scholar with the Robert S. Strauss Center for International Security and Law.

[37] He has previously served as Associate Editor of the IEEE Transactions on Aerospace and Electronic Systems and is currently for the Elsevier Advances in Space Research.
