Advances in synthesis techniques have produced colloids and
nanoparticles in a diverse array of shapes that can be assembled into
bulk structures. That bulk structure is strongly affected by particle
shape in idealized systems is widely established in the literature.
However, this literature leaves open three key questions: (i) We know
that shape affects structure, but how? (ii) Does shape continue to
matter in experimental systems where other interactions are present?
(iii) How do we tailor colloid shape for a target structure? In this
talk I will discuss recent work aimed at answering these questions.
