Dr. Lucas joined the Department of Molecular Biomedical Sciences as an Assistant Professor in January 2018. Dr. Lucas’s doctoral and postdoctoral training has spanned almost every subdiscipline of neuroscience, from molecular to systems to behavioral. Her doctoral research was conducted in the laboratory of Dr. Rita Cowell in the Department of Psychiatry and Behavioral Neurobiology at the University of Alabama at Birmingham (UAB). She combined molecular biology with genetic approaches in mouse models to determine novel region- and cell-specific gene targets of a transcriptional coactivator implicated in neurodegenerative and neuropsychiatric illness. Her thesis was highlighted by the remarkable discovery that the transcriptional coactivator acts as a master regulator of gene programs necessary for the maturation and maintenance of cortical interneurons. Following her successful PhD work, Dr. Lucas the lab of Dr. Roger Clem as a postdoctoral fellow in the Friedman Brain Institute at the Icahn School of Medicine at Mount Sinai in New York City. There she incorporated optogenetic approaches with in vitro slice electrophysiology to examine experience-dependent plasticity of neural circuits after emotional learning. She found that emotional memory encoding results in persistent downregulation of inhibition in the amygdala, the emotional processing center of the brain, through extensive plasticity of local inhibitory interneurons. In addition to her research accomplishments, Dr. Lucas also has taught graduate- and undergraduate-level courses in statistics and molecular genetics at UAB and New York University. Dr. Lucas particularly enjoys mentoring students toward the completion of honors and thesis projects, and she and her students have received numerous accolades for their research. Her research program at NC State will utilize novel techniques, including cell-specific optogenetics, chemogenetics, and neural ensemble tagging, to elucidate novel cells and circuits underlying fear-, anxiety-, and depression-related behavior in mouse models.

Research in the Lucas Lab is driven by a passion to improve the lives of people with mental illness. We conduct preclinical research in animal models to understand the mechanisms underlying susceptibility to psychiatric illness, with an emphasis on sex as a biological factor. Women are twice as likely as men to be diagnosed with fear-, anxiety-, and mood-based psychiatric disorders, but the exclusion of female subjects in preclinical research has hindered our progress in elucidating the sex-specific neurobiological bases of such illnesses. Our laboratory utilizes a multifaceted, systems-based approach that combines in vivo behavioral manipulations with ex vivo electrophysiological, transcriptional, anatomical, and endocrinological analyses in mouse models to dissect the neurobiological mechanisms underlying sex differences in behavioral states relevant to mental illness at the levels of the cell and the circuit. This research seeks to expand upon previous research conducted by ourselves and others, in hopes of attaining novel, potentially sex-specific, therapeutic targets for devastating mental illnesses disproportionally experienced by women, for which there are currently limited effective treatments and no cures.
