Dr. Menegaz studies the biology of feeding and chewing in humans and other mammals. Her research investigates how the material properties of diet affect the growth, structure, function, and evolution of craniofacial tissues. She is also interested in the biomechanics of feeding, such as temporomandibular joint (TMJ) kinematics and food-tooth interactions. Dr. Menegaz studies both healthy and dysmorphic phenotypes, such as osteogenesis imperfecta (OI) and temporomandibular joint disorders (TMJDs). Her lab uses three-dimensional geometric morphometrics, diffusible iodine-based contrast-enhanced computed tomography (diceCT), dynamic histomorphometry, and serum-based markers of bone physiology to investigate diet-related changes in the craniofacial skeleton and its associated soft tissues (e.g. muscles, cartilages, etc.).

Current Projects

  • Ontogeny and functional morphology of the rodent skull
  • Craniofacial development in osteogenesis imperfecta (brittle bone disease)
  • Aging and unloading-related atrophy of musculoskeletal tissues in the crania (tooth loss) and postcrania (limb loss)
