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 and Whole Genome Sequencing, using bioinformatic tools to develop population genetics and genomics interpretations of animal and plant species in relation to ecosystem patterns. Currently I’m studying the population genomics of two gastropod species from Antarctica. Additionally, I’m also collaborating with other projects on pinnipeds, blue tits, brittle stars, shellfish and palm trees.

Previous Research and Other Interests

I earned my PhD here at the University of Bielefeld under the supervision of Joe Hoffman. During my PhD project I primarily investigated the population genomics of four European shellfish species, but I could also collaborate on a number of other projects. During this time I was an Early Stage Researcher within the Marie Curie CACHE Initial Training Network (ITN).


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 bass.
