BIOGRAPHY

Ms. Dziedzic graduated from Salisbury University in 1996 with a bachelor’s degree in Biology, along with a minor in Chemistry. After graduation, she joined the laboratory of Tomás R. Guilarte, PhD in the Department of Environmental Health Sciences at Johns Hopkins University Bloomberg School of Public Health as a research technician. While continuing research in the lab, Ms. Dziedzic earned her master’s degree in biotechnology from the Krieger School of Arts & Sciences at Johns Hopkins University in 2001. She continued to work with and manage the daily operations of Dr. Guilarte’s lab with a relocation to Columbia University in 2010 and then to FIU in 2016. Currently, Ms. Dziedzic is a Research Associate in the Department of Environmental Health Sciences and manages the research operations of Dr. Guilarte’s Brain, Behavior, and the Environment laboratory.

Research in the lab focuses on mechanism-based neurotoxicology and neuroscience using behavioral, cellular, and molecular approaches. Studies in the lab range from using primary cultures of neural and glial cells to the application of multiple brain imaging technologies. Main projects in the lab focus on exposures to heavy metals, specifically lead (Pb) and manganese (Mn), and their effects on the brain, as well as the validation and use of a biomarker of brain injury and inflammation, Translocator protein 18 kD (TSPO).
