Dr Paulina-Carabajal (nicknamed “Premji”) is a dinosaur paleontologist at the Instituto de Investigaciones en Biodiversidad y Medioambiente (INIBIOMA), CONICET-Universidad Nacional del Comahue in the town of San Carlos de Bariloche in Rio Negro Province, northern Patagonia, Argentina. She received a Ph.D. in natural sciences from the Universidad Nacional de La Plata in 2009 under the supervision of Drs. Zulma Gasparini (UNLP) and Phil Currie (University of Alberta). She is also director of the Museo Paleontológico Bariloche since 2018.

Premji studies the cranial and endocranial morphology of dinosaurs and other extinct reptiles to understand the paleobiological implications of these anatomical regions as well as their impact on the evolution of each group. Her research also includes collaborations on the paleoneurology of Argentinean pterosaurs, lizards, and fossil anurans and crocodyliforms.


Premji´s general research interests include the morphology, evolution, and paleobiogeography of Cretaceous dinosaurs. She has participated in numerous field expeditions, mostly in Patagonia, but also in Alberta’s Dinosaur Provincial Park, Montana, the Gobi Desert, and Antarctica
