Noëlle GunstPh.D. (Adjunct Assistant Professor)


After a M.Sc. in Ecophysiology and Ethology (2002), Noëlle received a Ph.D. in Ecology (2008) from the University of Georgia (USA) under the supervision of Dr. Dorothy Fragaszy. During her Ph.D., Noëlle studied the development of foraging competence in the wild brown capuchin monkeys of Raleighvallen Nature Reserve, Suriname. From 2011 to 2015, Noëlle did a post-doctorate at the University of Lethbridge (Canada) under the supervision of Dr. Paul Vasey, during which she studied the development of sexual behaviors in Japanese macaques. Since 2016, she is an Adjunct Assistant Professor in the Department of Psychology at the U of L.

Noëlle and I have been working together since 1996 on several research projects (group movement in white-faced capuchins, fur rubbing in white-faced and brown capuchins, development of extractive foraging in brown capuchins, stone handling and fish eating in Japanese macaques, as well as stone handling, eye covering play, and robbing/bartering practice in Balinese long-tailed macaques), and conservation projects (population density of ebony leaf-eating monkeys and mona monkeys).

Since September 2015, Noëlle has been studying female-male mounting, monkey-deer mounting, and all-male groups in Japanese macaques, as well as the development of extractive foraging in Balinese long-tailed macaques.  She is also setting up a project on the sustainable wildlife-human coexistence on the island of Grenada (West Indies), with an emphasis on the community-based conservation of the introduced mona monkeys.

Camilla Cenni,  M.Sc. (Ph.D. student)

After a B.Sc. in Biological Sciences (2014) from the University of Bologna (Italy), Camilla joined the German Primate Centre and participated in several research projects focusing on color vision, olfactory communication, and cognition in captive and wild mouse lemurs and red-fronted lemurs. Part of these studies involved field observational and experimental work in the Kirindy forest of Western Madagascar, where she also studied three endemic species of chameleons.

In 2016, Camilla received a M.Sc. in Animal Behaviour from the University of Exeter (UK). Her main research project consisted in developing individual-based evolutionary models (via computer simulations) to understand the adaptive role of social play behavior in mammals. She focused on the coevolution between play-fighting and social systems. She also analyzed dominance hierarchies of male and female rhesus macaques based on win-loss agonistic interactions. Finally, she co-designed a coding system for video-recorded data on human-robot interactions in a playful context.

In January 2018, Camilla will start a PhD in our team, taking a Tinbergian approach to object play and tool use in different macaque species.
