The Standard Model (SM) of particle physics has provided a remarkable description of experimental results across a wide energy range.
Measurements of SM processes at the Large Hadron Collider (LHC) facilities continue to test our understanding of perturbative QCD,
higher order electroweak corrections, and sophisticated matrix-element and parton shower matching 
and merging techniques implemented in Monte Carlo event generator programs.
Despite the stunning success of the SM, several open questions remain such as the Higgs Hierarchy problem and the nature of Dark Matter.
Supersymmetry (SUSY) is a proposed extension of the Poincar\'e symmetry group that naturally 
stabilizes the Higgs mass and provides a weakly interacting Dark Matter candidate.
Experimental searches for strong and weakly produced SUSY particles that promptly decay have so far yielded no evidence for new physics.
However, several SUSY scenarios naturally predict the existence of long-lived particles
that require dedicated track and vertex reconstruction techniques,
and thus would have been missed by searches optimized for prompt decays.
In this seminar, I will review the current status of prompt searches, and then focus on the 
reconstruction techniques and search results for a range of long-lived SUSY searches using the ATLAS detector.
Moreover, I will discuss the next generation of silicon strip trackers planned for the High-Luminosity LHC upgrade project
that will carry the ATLAS physics program for the next decade and beyond.
