Description:Abstract:\n\nCommunication between the nervous system and immun
 e system is vital for maintaining health yet remains difficult to probe wi
 th precise temporal and spatial resolution. Our lab develops electrochemic
 al and microfluidic methods\, to close this critical gap in measurement sc
 ience. Specifically\, we have developed new electrochemical methods and el
 ectrode materials for fast-scan cyclic voltammetry (FSCV) detection which 
 have enabled us to expand these tools to new analytes involved in neuroimm
 une communication and other analytes previously not studied. FSCV is a cla
 ssic electroanalytical technique most often used in the brain to study neu
 rotransmitter signaling on a 100-ms timescale\; however\, our lab has push
 ed the boundaries of this technique by expanding its use to study neuroche
 mical events in immune organs like the lymph node\, intestine\, and spleen
 . In addition\, combining FSCV with microengineered platforms and devices 
 has provided us an experimental platform to probe neurotransmitter signali
 ng in multiple organs simultaneously ex vivo during communication. This ta
 lk will highlight some of our recent work in this area on method developme
 nt and the application of these methods to mechanisms of neurochemical-reg
 ulated cell signaling.\n\n&nbsp\;\n\nAbout the Speaker:\n\nAshley Ross is 
 an Associate Professor of Chemistry at the University of Cincinnati and fa
 culty in the Neuroscience Graduate Program. She earned her Ph.D. in 2014 f
 rom the University of Virginia under the guidance of Dr. Jill Venton. She 
 completed her post-doctoral training in Dr. Rebecca Pompano’s lab at the
  University of Virginia where she was an American Association of Immunolog
 y Careers in Immunology Fellow. She received the Alfred P. Sloan Fellowshi
