Principal Investigator

Dave Warren, PhD
David E. Warren, PhD 
Assistant Professor, Department of Neurological Sciences
Email: david.warren@unmc.edu
Dr. Warren is a cognitive neuroscientist and principal investigator at the University of Nebraska Medical Center. He studies memory and brain networks by combining neuropsychological, neuroimaging, and neurostimulation methods.

Graduate Students 

Connor Phipps
Connor Phipps, BS
Graduate Research Assistant
Email: connor.phipps@unmc.edu
As a graduate student in the Interdisciplinary Graduate Program in Biomedical Sciences, Connor studies the intrinsic functional networks of the brain utilizing a connectomics perspective. Specifically, he is interested in analyzing the properties of the intrinsic functional networks of the brain through graph theoretical measures to better understand the interactions between functionally connected units of the brain. His research goal is to apply noninvasive neurostimulation and connectomics to remediate memory in memory-impaired populations such as those affected by Alzheimer’s disease.

Meghan Ramirez
Meghan Ramirez, BS
Graduate Research Assistant
Email: meghan.ramirez@unmc.edu
Meghan is a graduate student in the Interdisciplinary Graduate Program in Biomedical Sciences with a focus in neuroscience. She received her BS in psychology with minors in sociology and biological anthropology at the University of Oregon in 2020. Her previous experience includes traumatic brain injury research, sleep and wake EEG, and effects of soundscape on the autonomic nervous system. Currently, she is interested in diversifying treatment and care options for individuals experiencing memory disorders.

Jennifer Sexton
Jennifer Sexton, BS

Lab Staff

Abigail Zatkalik
Abigail Zatkalik, BS
Clinical Study Coordinator
Email: azatkalik@unmc.edu
Phone: 402-836-9826
Abigail received her BS in psychology and anthropology with a minor in neuroscience from the University of Minnesota - Twin Cities in 2021. During her undergraduate career, she was the Study Coordinator for the MIND Group, which investigated behavioral, neuropsychological, and neurological functioning in rare genetic disease populations, namely RASopathies. Following graduation, she accepted her current position in the Warren Neuroscience Lab. Abigail’s future academic goals include pursuing a PhD in pediatric clinical neuropsychology with a neuroimaging focus in developmentally impaired populations. 

Lily Behm
Lily Behm, BA 
Clinical Research Associate I 
Email: lillian.behm@unmc.edu
After graduating from Hamilton College in 2020 with her BA in neuroscience, Lily accepted her current position as a Clinical Research Associate here in the Warren Neuroscience Lab. Prior to joining the lab, she worked in an Attention & Perception Lab studying cross-modal priming between olfaction and vision. Lily is currently interested in researching the development of brain networks that support memory and she plans to pursue a PhD in cognitive neuroscience.
