Xiaohu Xie's research focuses on investigating the molecular, neuropharmacological, and neurochemical mechanisms of drug addiction, decision making, and social interaction.
Lab Research Technician
Kristen assists in-vivo research investigating subsecond fluctuations in dopamine concentrations. Her research interests include exploring brain circuitry as well as changes in behavior due to chemical influences.
Sarah is interested in developing innovative fundamental tools needed to further current understanding of brain function and dysfunction. Presently she is focused on fabricating electrode arrays capable of detecting sub-second dynamics of glucose metabolism in the brain.
Lars was born in Chesterfield, VA, and lived there until he went to school at The College of William & Mary, where he received his B.S. in Chemistry with Honors. He participated in research all four years of undergraduate in the lab of Dr. Robert D. Pike. Outside of school, his interests include racing and restoring motorcycles, bass-fishing, and spending time with friends and family. He is interested in developing new techniques and hardware for use with FSCV to help understand the links between opioid peptides and catecholamine secretion in the central nervous system. He is also working to improve techniques for electrochemistry at single cells.
Will is a third-year student studying chemical engineering. He is currently working with Sam Smith, focusing on the development of a sensor to simultaneously monitor dopamine and glucose fluctuation.
Brennen assists in collection of in vivo dopamine fluctuations associated with decision making. Aside from school and research, Brennen enjoys photography, playing baseball and snowboarding.
Christie assists in-vivo research investigating real-time fluctuations of mesolimbic dopamine (DA). Current projects include ventral tegmental area mu opioid receptor manipulations to evaluate aspects of reward/ aversion, in addition to measuring DA in the ventral striatum utilizing electrochemical detection.
Catie is an undergraduate student in the Sombers Lab. She is currently planning on majoring in Biology with a concentration in Neurobiology and Physiology. Catie helps to support the research of Leslie Wilson who is working to quantify neurological oxidative stress present during chronic L-DOPA treatments.
Edwin's research is focused on manipulating the fundamental surface chemistry of carbon-fiber microelectrodes in order to improve their performance as sensors for neuroscience studies.
Lingjiao's research involves simultaneously monitoring the effects of L-DOPA on dopamine and hydrogen peroxide dynamics in the brain and investigating ventral tegmental area mu opioid receptor modulation of phasic dopamine release in the ventral striatum.
Nastassja was born in Shreveport, LA in 1986. She earned a B.A. in Anthropology, Philosophy & Religion from Cornell College in 2007. After working as a developmental counselor with disabled children and young adults for a few years, she returned to school and graduated with a B.A.S. in Interdisciplinary Chemistry & Biology from The Evergreen State College in 2013. She was admitted to NCSU in the Spring of 2014 as a Ph.D candidate, studying Analytical Chemistry. She joined the Sombers research group in the Summer of 2014. She enjoys vintage video games, reading, rugby and especially traveling.
James received his B.S. degree in Chemistry with honors from Lenoir-Rhyne College in Hickory, NC. He joined the group in 2008 and began work on advancing microelectrode technology for neuroscience applications and studying real-time fluctuations of neurotransmitters in the rat brain with fast scan cyclic voltammetry. Besides research, James enjoys cooking, bicycle riding, taking his dog to the park, and Formula One racing.
Born in Coburg, Germany. Moved to the US in 2001. Undergraduate at NCSU from 2006-2010. Andy is interested in improving the electrochemical detection and characterization of various neuropeptides. His personal interests are playing and/or watching soccer, football, or any other outdoor sport.
Trisha is a first year student who works with graduate student, Leslie Wilson, to characterize chronic electrodes. In the future she is interested in studying behavior changes associated with neurochemical fluctuations. She is currently exploring her interests in biochemistry and biology. Her long term goals include continuing to graduate or medical school. Outside of the lab, Trisha enjoys playing tennis and the piano.
Samantha Smith is a member of the Sombers Lab in the Department of Chemistry. Her research meets at the interface of Electrochemistry and Neurobiology. She studies the relationship between behavior and the transients of both glucose and dopamine in vivo using a novel biosensor.
Administrative Support Specialist
Robin graduated from NCSU with a BA in English Literature and a minor in Accounting. She worked for the North Carolina Real Estate Commission for 14 years investigating complaints against real estate agents. She spent 6 years in the Legal Department and 8 years as an Auditor/Investigator at the Real Estate Commission. Robin joined the NCSU Chemistry Department in March of 2010. She supports four research professors and their research groups. She loves her job and especially enjoys interacting with the students. In her free time, she enjoys spending time with her two children – Parker and Maggie.
Leslie's research interests include advancing quantitative electroanalytical methods to study neurological oxidative stress.
