I was born in Belgium where I studied Environmental Sciences at Howest, University College West Flanders and Ghent University, shortly intervened by Erasmus studies at Radboud University in the Netherlands. Now, I’m a PhD candidate at the Department of Geography, University of the Aegean. My research interests are faunistics, conservation ecology, pollination ecology, systematics and the biogeography of bees. My current research focuses on the biogeography of the bees in the Aegean Archipelago using a phylogenetic and faunistical approach.

My first step into the world of bees came around the turn of the century. I had always a broad interest in nature and continue to do so, but I definitely “got stung” by the study of bees. I have been involved in “citizen science” projects addressing the importance of bees and pollination. Over the past years I've had the opportunity to study bees in several parts of the world. An unforgettable experience was working in the Badlands National Park in South Dakota, the Bee Inventory and Monitoring Lab (USGS), and Smithsonian Institution under the supervision of Sam Droege.

Now, I’m glad to be back in Greece (I was in the lab for a short while in 2007 and 2008). It is one of those rare places where you can study over 1,000 species of bees and there will still be much to discover. So far, I've enjoyed exploring islands, climbing mountains, and I’m looking forward to continue exploring this bee hotspot.

Since the beginning of my explorations I have been accompanied by my Nikon camera. I am especially fond of macro photography of insects. You can take a peek at my Habropoda photostream.
