Riccardo Castiglia was born in Rome on 12-10-1969, and holds a full university career at the Department of Animal and Human Biology, now the Department of Biology and Biotechnology "Charles Darwin" of the University of Rome "Sapienza". He graduated in Biological Sciences in 1994 and earned his PhD in Animal Biology in 2001. Since 2006 he has been a structured researcher. Since 2003 he teaches Comparative Anatomy of Vertebrates for Biology Degree and since 2010 teaches Evolutionary Vertebrate History for Master Degree in Ecobiology. Since 2007, he has been a member of the College of PhD students in Animal Biology. He has consulted Agriconsulting sp To the IEA (Institute of Applied Ecology) regarding the drafting of the management plans of the National Park of the Tuscan Archipelago and of the Gargano National Park (amphibians and reptiles). He is a member of the editorial body of the magazinesISRN Zoology , TheScientificWorldJOURNAL, PLOSone and Biodiversity Data Journal . He acts as a referee for more than twenty magazines with impact factor. His research lines are about cytotoxomy and chromosomal evolution in rodents and reptiles, the phylogeography of small mammals in the Mediterranean region, and the evolutionary biology of the chromosome of the Musolinus domesticus . In addition to Italy, he took part in field research in Africa (Ethiopia, Tanzania, Kenya, Zambia) and Mexico (Jalisco and Chiapas). He is author of 70 articles on peer reviewed scientific journals (including: Biological Journal of the Linnean Society ,Biological Invasions , Chromosome Research , Evolution , Heredity , Journal of Zoology , Journal of Evolutionary Biology , Molecular Phylogenetics and Evolution , Proceedings of the Royal Society B-Biological Science , Mammal Review ) and five chapters (including three for volume "Wildlife of Italy, Mammalia II Erinaceomorpha - Soricomorpha - Lagomorpha - Rodentia").
