Ana Barrios (Fed)

NRC Postdoctoral Research Associate

Dr. Ana C. Barrios joined the Cell Systems Science Group led by Dr. John T. Elliott. Ana received her Ph.D. in civil and environmental engineering from Arizona State University (ASU) in 2021.  In her dissertation, she studied the interactions between different carbon-based nanomaterials and multiple organisms to establish structure-function-relationships. Particularly, she focused on understanding nanomaterials’ properties for water treatment applications.

Ana first arrived at NIST through an NSF-NIST supplement, where during her doctoral studies, Ana was an intern at the Infrastructure Materials Group from the Engineering Laboratory division from 2019 to 2020. As an NRC postdoctoral researcher, she aims to develop a robust 3D in vitro model of the human gut to assess the effects of nano and micro plastics.

Research interests

  • Micro and nano plastics / nanomaterials
  • Cell characterization measurements
