Vertebrate paleontology, vertebrate comparative anatomy
I have been analyzing sequence of anatomical evolution, both skeleton and soft tissue, of the neck in reptiles by combining information on soft tissues (muscles, ligaments, blood vessels, etc.) obtained from Extant animals and patterns of evolutionary changes in skeletal morphology observed in the fossil record. I am also working on the morphology of brain endocasts of fossil reptiles, regionalization of the axial musculoskeletal system in Extant limb-reduced squamates such as snakes, as well as on fossil specimens of reptiles.
