Rossignol Lab Members

Read the biographies of current and past lab members of the Rossignol Lab. 
Julien Rossignol
Julien Rossignol

Principal Investigator

Julien grew up in France. He holds degrees in cell biology, biochemistry, molecular biology, biophysics and neuroscience from the University of Nantes and the University of Orleans in France. As a faculty member in the College of Medicine, Julien leads a team of undergraduate and graduate students and medical students working to deliver cell therapy and genomic editing to the brain through human-made dendrimer molecules. The approach could apply to treatment for conditions such as stroke, glioblastoma, Alzheimer’s and Huntington’s disease.

Research Associate

Bhairavi grew up in Chennai, India. She received her bachelor’s degree in genetic engineering from SRM University, Chennai and completed a one-year research/work experience in the Clinical Genetics lab at Christian Medical College, Vellore. Bhairavi is currently working on dendrimer based gene and drug delivery for Huntington’s disease, glioblastoma multiforme and stroke.

Bethany MacDonald, Graduate Student
Bethany MacDonald

Graduate Student

Bethany grew up in Gladstone, Michigan. She has a undergraduate degree in neuroscience with a minor in psychology. Bethany along with other graduate students are working on delivering large plasmids to specific cell types of the brain such as glial cells. She is also working on processing the stroked brain tissue following dendrimer nanomolecule therapy.

John Gallien

Graduate Student

John grew up in Los Gatos, California. He received his bachelor’s degree in psychology from San Diego State University. After working as a substance abuse counselor, he earned his master of science in clinical neuropsychology from the University of Texas at Tyler, where his internship focused on the assessment and diagnosis of dementia patients. He received a master's in neuroscience at CMU and recently completed a graduate clinical fellowship with MI-LEND. He is currently working on the treatment of stroke and HD using dendrimer nanomolecule delivery.

Arjun Poudel, Graduate Student
Arjun Poudel

Graduate Student

Arjun grew up in Nawalparasi, Nepal. He received his bachelor's degree in physical therapy from Rajiv Gandhi University of Health and Sciences in Bangalore, India. After working as a physical therapist he came to Central Michigan University to receive his master's degree in health services administration and is currently a graduate student in neuroscience. Arjun is currently working with other graduate students on their projects with stroke and dendrimer nanomolecules.
