Abstract.
In this lecture I will discuss the following topics:

- Twistors in 4 flat dimensions (Massless particles, constrained phase space (x^m,p^m) versus twistors; Physical states in twistor space)

- Introduction to 2T-physics and derivation of 1T-physics holographs and twistors (Emergent spacetimes & dynamics, holography, duality; Sp(2,R) gauge symmetry, constraints, solutions and (d,2); Global symmetry, quantization and the SO(d,2) singleton; Twistors for particle dynamics in d dimensions, particles with mass, relativistic, non-relativistic, in curved spaces, with interactions)

- Supersymmetric 2T-physics, gauge symmetries & twistor gauge (Coupling X,P,g, gauge symmetries, global symmetries; Covariant quantization, constrained generators & representations of G_super; Twistor gauge: supertwistors dual to super phase space. Examples in d=4,6,10,11.) (An expanded version of these lectures can be found in [1].)
