+shortdescription: Optimization of charged-particle reconstruction algorithms in future Muon Colliders
+description: >
+  A muon-collider has been proposed as a possible path for future high-energy physics.
+  The design of a detector for a muon collider has to cope with a large
+  rate of beam-induced background, resulting in an unprecedentedly large multplicity of particles entering the
+  detector that are unrelated to the main muon-muon collision.
+  The algorithms used for charged particle reconstruction (tracking) need to cope with such "noise" and be
+  able to successfully reconstruct the trajectories of the particles of interest, which results
+  in a very large conbinatorial problem that challenges the approaches adopted so far.
+  The project consists of investigating how the tracking algorithms can be improved by utilizing a combination of
+  directional information from specially-arranged silicon-detector layers and more advanced reconstruction techniques and algorithms
+  available in the experiment-generic ACTS tracking library adapted to the specific environment expected for a Muon Collider detector.
+  The project allows the fellow to mix acquiring good technical skills and the ability to innovate state-of-the-art tracking algorithms in this less-explored environment.

+shortdescription: Software infrastructure and detector layout exploration for detectors at future wakefield-based colliders
+description: >
+  Wafkefield-based acceleration techniques promised tens of GeV of acceleration in under a meter. Such concepts have been demonstrated in laboratories with single cells.
+  Despite this promise, only recently a coordinated effort to study end-to-end a complete collider design based on such technology has started.
+  Within this project, the question of what type of detector would be best suited to extract the best physics out of such very-high-energy electron-positron (or electron-electron, or photon-photon) collisions remains largely unexplored.
+  In this project, you will help building up the software infrastructure, within the key4hep framework, that will allow such detailed studies and start exploring detector layout assumptions and their implications.
