DESCRIPTION:Dr Kristen Kozielski\, Max Planck Institute for Intelligent Sy
 stems\, GE.\nNeural implants are devices that can enable doctors and engin
 eers to electrically sense or modulate neural behavior. A nano- or microsc
 ale neuroprosthetic that operates wirelessly could be implanted using mini
 mally-invasive routes\, potentially avoiding surgical intervention. Magnet
 oelectric materials\, those that couple magnetic fields to electric fields
 \, allow us to wirelessly generate electric signals using input magnetic s
 ignals\, but also allow us to sense electric signals via output magnetic s
 ignals. Herein\, I will introduce the capability to wirelessly interface w
 ith neurons using magnetoelectric materials. As these materials directly c
 reate an electric field\, they can modulate neuronal activity without any 
 biochemical or genetic cell manipulation. I will describe their chemical s
 ynthesis and characterization\, and demonstrate that they generate electri
 c signals in response to the application of a magnetic field. Finally\, I 
 will show their ability to both positively and negatively modulate neurona
 l behavior in vitro\, and will conclude with a discussion on potential fut
 ure applications of these materials for wireless medical intervention.\n\n
 Bio\nKristen Kozielski completed her Ph.D. in Biomedical Engineering at Jo
 hns Hopkins University in the fall of 2016. Her thesis work focused on pol
 ymeric nanoparticles for DNA and RNA delivery\, primarily with application
 s in brain cancer. She is currently a postdoctoral researcher at the Max P
 lanck Institute for Intelligent Systems\, working in multiferroic nano- an
 d micromaterials for applications in wireless medical technologies. Kriste
 n’s research is published in twenty-one peer-reviewed journal articles\,
  and her work has been highlighted by Science Translational Medicine and t
 he US NIH National Institute for Biomedical Imaging and Bioengineering. Ov
 er the course of her career\, she has received funding to support her work
  from the US NIH\, the Whitaker Foundation\, and the ARCS Foundation.\n\nV
