Dr. Yannick Marchalant obtained his Ph.D. from the University of Caen, France in 2004. After graduating, he moved to the University of Arizona and then onto The Ohio State University as a post-doctoral researcher for 4 years. He then became a research assistant professor in 2008 at The Ohio State University for 2 years. He moved back to Europe for 4 years in Aix-Marseille University, France and joined​ the Psychology Department at Central Michigan University in the fall of 2014 as an assistant professor. He has been working for 15 years on neurodegenerative disease, in particular Alz​heimer's disease, and has studied notably the role of neuroinflammation in brain aging as well as the influence of the endocannabinoid system on the regulation of inflammatory processes in the context of Alzheimer's disease.

Research Interest:

For the last 20 years, I have been working on different aspects of normal and pathological aging (behavioral to molecular approaches), notably Alzheimer's disease.

More recently I have been more focus on the role of inflammatory processes in the development of Alzheimer's disease and trying to identify ways to target them.

We are currently actively looking at:

  • The role of early inflammation (pre-symptomatic) in the 5xFAD mouse model of Alzheimer's disease.
  • The role of early systemic chronic inflammation in the regulation of amyloid plaques formation and neuronal structure in the NL-G-F knock-in mouse model of Alzheimer's disease.

We are hoping that those projects will lead to a better understanding of the contribution of inflammatory processes in the neurodegenerative context that is Alzheimer's disease.
