Dental microwear analyzes microscopic scars on the occlusal surfaces of animal teeth (mainly mammals) in order to evaluate the dietary habits of the studied species. This method can be applied both to extant and extinct mammals and has been used with different techniques: scanning electron microscopy, stereomicroscopy, and confocal microscopy.
My research focuses on the feeding ecology of extinct muroid rodents and tritylodontids (target tissue tooth enamel) as well as giant ground sloths (target tissue orthodentine).
