This section presents the members of the lab, including current and past students and outside collaborators.

Principal Investigator

Roberto Refinetti, Ph.D.
The head of the lab is Dr. Roberto Refinetti, a biopsychologist with expertise in organismal physiology and behavioral neuroscience. Ph.D. 1987 Personal page

Collaborators

Giuseppe Piccione, D.V.M.
The most frequent collaborator has been Professor Giuseppe Piccione, a research veterinarian from the University of Messina, in Sicily (Italy). D.V.M. 1989 Personal page

Gianluca Tosini, Ph.D.
Collaboration was also initiated with Professor Gianluca Tosini, a molecular biologist at Morehouse School of Medicine, in Atlanta (Georgia). Ph.D. 1994 Personal page

Mamane Sani, Ph.D.
	Dr. Mamane Sani, from the University of Maradi (in Niger, West Africa) visited the lab as a postdoctoral fellow under the Fulbright Visiting Scholar Program for six months in 2014 to enhance his skills in chronobiological methods of time series analysis.

Franz Halberg, M. D.
	For several years, the lab had the the honor of collaborating in various projects with Professor Franz Halberg, one of the forefathers of circadian physiology and the creator of the term circadian. Still active in research and scholarship past his 90th birthday, Halberg passed away in June 2013.

Doctoral and Postdoctoral Advisers
	Dr. Refinetti's graduate adviser was Professor Harry Carlisle, at the University of California, Santa Barbara. The research area was thermal biology.
	Dr. Refinetti's postdoctoral adviser was Professor Michael Menaker, at the University of Virginia. The research area was circadian biology.
