Monotone Simultaneous Paths Embeddings in $\mathbb{R}^d$ [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2018
We study the following problem: Given $k$ paths that share the same vertex set, is there a simultaneous geometric embedding of these paths such that each individual drawing is monotone in some direction?

Asymmetrical interference effects between two-dimensional geometric shapes and their corresponding shape words. [PDF]

open access: yesPLoS ONE, 2014
Nativists have postulated fundamental geometric knowledge that predates linguistic and symbolic thought. Central to these claims is the proposal for an isolated cognitive system dedicated to processing geometric information.
