Lab Members

Dr. Lily Yan, Principal Investigator

I received my Ph.D. in Physiology from Kobe University School of Medicine (Japan) in 2000 and had a post-doctoral training at Columbia University, during which my research focused on the molecular and neural mechanisms of circadian rhythms. I joined the faculty at Michigan State University in 2008, since then my research program has focused on the interplay of circadian clocks and ambient light in the regulation of emotion and cognition.  For more information, see my CV or email me.

Katrina Linning-Duffy, Laboratory Manager

KatrinaKatrina attended Claflin University and the graduate program in Microbiology at Michigan State University. She completed her courses and began working as a Research Technologist in Dr. Karl Olson’s laboratory in MSU’s Physiology Department. Since then she has worked in a few neuroscience labs, through which she has gained extensive experience in studying neuropetides, neurotransmitters, animal behaviors as well as in lab management.

Allison Costello, Graduate Student

I graduated from Wright State University in 2018 with a Bachelor of Science in Psychology with a concentration in Behavioral Neuroscience. As an undergraduate I worked in the laboratories of Dr. Dragana Claflin and Dr. Michael Hennessy, researching early life stress and inflammation. In the Yan lab I am currently studying how light affects neuroinflammatory response and emotion, and the mechanisms behind it.

Carleigh Vandenbrook, Research Assistant

Carleigh is currently a junior at Michigan State University majoring in human biology.  She plans on attending medical school after graduation in her hometown of Chicago. Outside of the lab Carleigh volunteers at a crisis hotline and holds a position in her sorority’s executive board. She joined the Yan Lab in 2020 and is currently interested in how light modulates neuroinflammation, emotion, and cognition.

Sarah Hoogstraten, Research Assistant

Sarah is a sophomore in the Lyman Briggs College at Michigan State University majoring in Neuroscience, which she plans to pursue a PhD in. Outside of the lab, Sarah is a member of the Spartan Marching Band Color Guard and works at a veterinary clinic. She joined the Yan lab in 2021.

Emma Beaver, Research Assistant

Emma is currently a sophomore in the College of Natural Science at Michigan State University majoring in human biology. She plans to attend medical school upon the completion of her undergraduate degree. Outside of the lab, Emma volunteers as an ESL tutor with the Refugee Development Center in East Lansing and is a member of the Pre-Medical Association student organization. She joined the lab in 2021.
