  In these lectures I will discuss the following topics:
  (1) Twistors in 4 flat dimensions: Massless particles; constrained phase
space (x,p) versus twistors; Physical states in twistor space.
  (2) 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.
  (3) Twistors for particle dynamics in d dimensions, particles with mass,
relativistic, non-relativistic, in curved spaces, with interactions.
  (4)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.
  (5) Supertwistors and some field theory spectra in d=4,6: Super Yang-Mills
d=4, N=4; Supergravity d=4, N=8; Self-dual tensor supermultiplet and conformal
theory in d=6.
  (6) Twistor superstrings: d+2 view of twistor superstring in d=4; Worldsheet
anomalies and quantization of twistor superstring; Open problems.
