Silvia's research is on the functional morphology of dinosaurian claws, especially of the dromaeosaurs. She uses a combination of comparative shape analysis with living birds and mammals, finite element functional experimentation, and field observations on the closest living analogues to test hypotheses about the function of the unusual morphology found in this extinct clade.
Silvia also works on paleoenvironmental problems using stable isotope analysis. She has a paper in press in Palaeogeography, Palaeoclimatology, Palaeocology on stable isotope proxies of environment from crocodilians and mammals from the Early Pleistocene Olduvai Gorge hominin sites in Tanzania.
She now works for Paleo Solutions out of Denver, Colorado.
