The geometries and topologies of leaves, flowers, roots, shoots, and their arrangements
have fascinated plant biologists and mathematicians alike. As such, plant morphology is …

… In collaboration with Washington Mio, we solved this problem by applying spherical
harmonics analysis to the Shh gene expression domains in chick embryos (Fig. 13A). OPT is …

Using a differential-geometric treatment of planar shapes, we present tools for: 1) hierarchical
clustering of imaged objects according to the shapes of their boundaries, 2) learning of …

We study shapes of planar arcs and closed contours modeled on elastic curves obtained by
bending, stretching or compressing line segments non-uniformly along their extensions. …

Numerous lines of evidence point to a genetic basis for facial morphology in humans, yet little
is known about how specific genetic variants relate to the phenotypic expression of many …

… Special thanks to other members of the Deng lab and Mio lab for technical help and
discussions on this project; DJ is supported by Dissertation Research Grant Award from Florida …

The human face is a complex assemblage of highly variable yet clearly heritable anatomic
structures that together make each of us unique, distinguishable, and recognizable. Relatively …

The idea that we can reconstruct a human face from a DNA sample has great appeal: DNA
from a crime scene could be used to create a facial image of a suspect; the faces of …

Taxonomic identification of pollen and spores uses inherently qualitative descriptions of
morphology. Consequently, identifications are restricted to categories that can be reliably …

The human face is an array of variable physical features that together make each of us unique
and distinguishable. Striking familial facial similarities underscore a genetic component, …
