Biosketch

Dr. Juarez believes that by understanding the circuit and molecular mechanisms that underlie individual resilience or susceptibility to substance use disorders, novel treatments to disorders  will be discovered. She began her scientific training as an undergraduate at Florida International University in the Minority Biomedical Research Support- Research Initiative for Scientific Enhancement (MBRS-RISE) program and as a Summer Undergraduate Research Program (SURP) fellow at Boston University. In these programs, she contributed to investigations that sought to determine how circulating hormones in female mice contributed to differences in learning, memory and mating behaviors. She began a post-baccalaureate fellowship in Icahn School of Medicine at Mount Sinai’s Post-Baccalaureate Research Education Program (PREP) in August 2010 where she joined Dr. Ming-Hu Han’s laboratory. Then as a graduate student at Mount Sinai, she received an NIAAA funded F31 NRSA-Diversity recipient and determined how midbrain dopamine neurons mediate individual differences in alcohol drinking behaviors.

Dr. Juarez  completed her Ph.D training in December 2016 and joined the laboratories of Drs. Larry Zweifel and Charles Chavkin at University of Washington in January 2017 to elucidate how potassium channel subunits contribute to the regulation of cellular physiology and associative learning. She learned how to use viral based CRISPR-Cas9 gene editing approaches to meet these goals. She received a MOSAIC K99/R00 from NIDA in September 2021, which is  focused on determining whether  ventral tegmental area (VTA)  dopamine subpopulations uniformly or distinctly regulate opioid associative learning, through the use of high throughout analysis of mouse behavior, CRISPR-Cas9 gene editing technology, circuit dissecting electrophysiology, and in vivo photometric methods to analyze neural activity.

Dr. Juarez is  now  an Assistant Professor at the University of Maryland, Baltimore School of Medicine in the Department of Anatomy and Neurobiology. The Juarez Lab  is focused on understanding how regulators of cellular excitability contribute to healthy and disordered behaviors. Her lab uses combinatorial approaches to accomplish these goals, such as patch-clamp electrophysiology, in vivo monitoring of neural activity, CRISPR/Cas9 gene editing, and mouse models of neuropsychiatric disorders. Throughout her research tenure, Dr. Juarez has been committed to the promotion and support of underrepresented individuals in science and to the mentoring of the next generation of scientists. She has  experience in establishing and growing equity, diversity and inclusivity initiatives in academic environments.
