David Vendrami



My primary research interest is the application of genetic/genomic-based analysis to address relevant ecological and evolutionary questions that are useful for the management and conservation of animal species. My work focuses on the exploitation of NGS data, such as RAD sequencing, using bioinformatic tools to develop population genetics and population genomics interpretations of animal species in relation to ecosystem patterns. Currently I’m investigating how human-driven ocean acidification is impacting on species with calcareous skeletons, specifically on four shellfish species. This project is part of a Marie Curie Initial Training Network called CACHE (calcium in a changing environment). I’m also collaborating with other projects on seals, blue tits and palm trees.

Previous Research and Other Interests

As part of my Master’s degree at the University of Ferrara, I spent one year at the NOAA’s Southwest Fisheries Science Center in Santa Cruz to conduct research on the life-history traits of steelhead trout (Oncorhynchus mykiss) as revealed by genetic analysis.

In summer 2012 I joined the Marine Turtle Rescue Center (CRTM) located in Linosa Island to study the ecology and behaviour of the endangered species Loggerhead sea turtle (Caretta caretta) and to contribute to the monitoring of cetacean species around Linosa Island.

In addition to my research activity, I like focusing my attention on playing Capoeria, juggling, slacklining and playing the guitar.
