Doctoral candidate Brenna Hart-Farrar synthesizes bone histology from ground thin sections with 3D structure revealed through synchrotron phase-contrast scanning (Canadian Light Source) and microCT (MICRO, U. Arkansas). Brenna is quantifying cell + vascular structure and tissue types to reveal growth and life history from dinosaur and mammal bone, literally bringing histology into the third dimension. She engages in extensive fieldwork in Montana with co-advisor Prof. Holly Woodward Ballard.
