Adam has successfully defended his Ph.D and has graduated this past June! He will be leaving us to work in industry. Wilfred has also successfully defended his master’s thesis and graduated this past June as well! He will be leaving us to further his education in a purist of a Ph. D. Good luck gentlemen and best of luck in your future endeavors!
Members of the Heien lab presented their research at the annual department symposium. Kate gave an oral presentation while the rest of the lab presented posters. Drew and Adam won best poster presentation, and James won the best visualization “eye candy” poster award!
Check out some photos taken by the department here!
Katherine L. Parent gave a presentation to the University of Arizona Chemistry and Biochemistry Department on April 16th, 2015, detailing some of her work in Electrochemical investigation of dopamine dynamics in rodent models for the BCP Journal Club.
Richard F. Vreeland, Nicholas D. Laude, Sean Lambert, and Dr. Michael L. Heien have published a new peer-reviewed publication. The publication outlines a new technique our lab has developed to etch thin films of conductive polymers for the fabrication of microelectrodes. This technique is an alternative to reactive ion etching, and offers similar capability while only costing the user about $100 (for a microwave from Home Depot) and is entirely benchtop. The microwave etch is used to fabricate a microchip electrophoresis platform where neurotransmitters are separated and detected. The sensor is characterized and compared to more common materials like carbon. Congratulations!
Christopher W. Atcherley, Nicholas D. Laude, Katherine L. Parent, and Dr. Michael L. Heien have published a new peer-reviewed publication. The publication outlines a new technique our lab has developed to measure the tonic or “basal” concentration of dopamine in vivo. The technique exploits the strong adsorption interaction between dopamine and carbon fiber microelectrodes. Characterization and optimization of the technique is described. Congratulations!
Christopher W. Atcherley, Richard F. Vreeland, Esther Sanchez-Gomez, Dr. Eric B. Monroe and Dr. Michael L. Heien have published a new peer-reviewed publication. The publication outlines the utility of a zero-phase filter for fast scan cyclic voltammetry experiments to avoid traditional filtering artifacts, as well as the filter’s utility in filtering amperometric data from PC12 cell exocytosis. The authors are also sharing their program on this website, in the software section. Congratulations!
Catherine L. Kramer has been awarded with a Research Assistant position at University of Arizona’s Mass Spectrometry Facility for the duration of the 2013-2014 academic year. Catherine will be running samples on various mass spectrometers and learning to diagnose and fix problems that arise with instruments. Congratulations Cat!
Christopher W. Atcherley gave a presentation to the University of Arizona Chemistry and Biochemistry Department on April 26th, 2013, detailing some of his work in Quantifying tonic and phasic neurotransmission with fast-scan cyclic voltammetry. Christopher was selected as this year’s David E. O’Brien Graduate Fellow, and will go on to present his work at a Gordon Conference later this year. Congratulations Chris!
Nicholas D. Laude, Christopher W. Atcherley, Eric B. Monroe, and Michael L. Heien presented the kinetic calibration method for in-vivo dopamine measurements at the BioPhest 2013 conference on 4/20/2013 at Arizona State University in Tempe, AZ.
