Postdoctoral Scientists


Amy Christensen, PhD

Senior Postdoctoral Scientist


B.S. University of California, Los Angeles, 2005
Ph.D. University of California, Los Angeles, 2012

Amy was born and raised in San Diego, CA. Her doctoral work at UCLA involved looking at the molecular mechanisms of membrane estrogen receptor signaling in the context of female sexual behavior. Her current work focuses on Alzheimer’s disease in females and the utility of hormone therapy. When she’s not working in the Pike lab, she likes to run half marathons and watch lots of football (Go Chargers!).


Camille Sample, PhD

Postdoctoral Scientist


BS, Washington & Lee University, Lexington, Virginia, 2011
PhD, American University, Washington, D.C., 2016

Camille grew up in Louisiana and relocated to downtown Los Angeles from Washington, D.C. Her doctoral work examined how Western diet consumption interferes with learning and memory processes involved in feeding. In the Pike lab, she investigates sex differences in neuroinflammation and Alzheimer’s disease risk. Outside of the lab, she practices yoga and cans seasonal vegetables.


Terri Stephen, PhD

Postdoctoral Scientist


BS, University of Aberdeen, United Kingdom, 2011
PhD, University College London, United Kingdom, 2016

Terri was born in South Africa and moved to Scotland as a teenager. Her doctoral work at UCL assessed the importance of mitochondrial trafficking in astrocytes. During her postdoctoral appointment at Eli Lilly she looked at how synapses are affected in Alzheimer’s disease and also ran pre-clinical drug trials. Her current work focuses on microglia and sex difference in Alzheimer’s disease. When she’s not working in the Pike lab, she likes to stay active (preferably at the beach) and fill up her passport with stamps.

Undergraduate Researchers


Mehul Khetrapal

Undergraduate Research Assistant

Mehul was born in Bangalore, India and raised in Singapore. He is currently a sophomore at USC majoring in Computational Neuroscience with a concentration in Biomedical Engineering and a minor in Computer Programming. His current work focuses on optimizing microglia cell analysis through automation. In his free time, Mehul likes to read non-fiction and play tennis!


Sydney Lance

Undergraduate Research Assistant

Sydney is from Prior Lake, Minnesota. She’s currently a junior at USC studying neuroscience with a minor in gerontology. Right now her work focuses on peripheral inflammation and its role in Alzheimer’s. Outside of the lab, Sydney enjoys playing rugby and trying new foods around LA.
