We aim to understand the evolution and regulation of cooperative relationships. I use grooming and food sharing to gain insights into the social lives of vampire bats. My lab starts Fall 2018 at The Ohio State University.

Scientific conferences are some of the biggest highlights of my year. I just attended the Behavior2017 Conference in the beautiful seaside town of Estoril, Portugal. I’m still early enough in my scientific career that when I attend a conference, I … Continue reading
New timeline July 30- August 4, 2017: I’ll be at the Behavior 2017 Meeting in Portugal September 3, 2017: Team Vampire wraps up captive experiments and we begin our fieldwork led by Dr. Simon Ripperger. October 15, 2017: I leave Panama. … Continue reading
Our latest paper here. Also some early press here. There are actually three recent papers on social networks and the benefits of network size in primates (by Laurent Brent and co-authors), songbirds (by Josh Firth and co-authors), and bats (by me … Continue reading
“New” ideas are rarely new. In science we stand on the shoulders of giants and whenever I read the works of the giants, I often find that many ideas or discoveries– that I thought were “mine” or belonged to some … Continue reading
Spix’s disc-winged bat Thyroptera tricolor has suction cups (yes, suction cups) on its thumbs, and it uses these to cling to the smooth surface of young, furled Heliconia leaves. I’ve wanted to see a disc-winged bat since I was about … Continue reading

In 1984, Gerald Wilkinson published a paper in Nature showing that vampire bats share food in the form of regurgitated blood, within groups that contain both kin and non-kin. This was one of the fi… Source: Revisiting Wilkinson 1984
