Lisa

Lisa Topolnik, PhD

Lisa is our scientific leader and the soul of the laboratory. She holds a faculty position in Biophotonics at the Department of Biochemistry, Microbiology and Bioinformatics at Université Laval.

She graduated from the Odessa National University in the field of Human and Animal Physiology and received her PhD in the field of Neurobiology from the Bogomoletz Institute of Physiology (2000) in Ukraine.

She then moved to Canada to pursue postdoctoral training, first, with the group of Dr. Mircea Steriade at Université Laval and, second, with Dr. Jean-Claude Lacaille at Université de Montréal. In 2007, she moved back to Université Laval and received the University Faculty Award for Women from Natural Sciences and Engineering Research Council of Canada to develop her research program.

 

Sarah

Sarah Côté, Lab technician

Sarah is in charge of mouse colonies, as well as basic molecular biology and immunohistochemistry techniques.

 

vincent

Vincent Villette, postdoc

Using in vivo two-photon Ca-imaging of hippocampal interneurons in head-restrained behaving mice, Vincent explores the mechanisms of cell-specific recruitment during epilepsy and AD.

 

Einer

Einer Munoz, PhD student

Einer is in the lab since September 2014. Using a combination of patch-clamp recordings and neuroanatomy, he is investigating the physiological features of specific types of interneurons and the role of gap junctions.

 

Xiao

Xiao Luo, PhD Student

Xiao joined the lab in January 2014. He is using a combination of patch-clamp electrophysiology & optogenetics to target specific glutamatergic inputs to hippocampal interneurons.

 

Ruggiero

Ruggiero Francavilla, PhD student

Ruggiero Francavilla is using patch-clamp electrophysiology, neuroanatomy, behavioural analysis and imaging in vivo to explore VIP-interneurons in the hippocampus during aging and AD.

 

Olivier

Olivier Camiré, PhD student

Olivier joined our lab in September 2010, first, as an undergraduate and then as a master student. His research project is to investigate the calcium fluctuations in dendrites of hippocampal interneurons. He becomes an expert in two-photon Ca2+ imaging in combination with patch clamp recordings in hippocampal slices in vitro.
