Former Students

Tim Dickhudt began his research in the summer of 2005 and worked for 3 years on projects related to the ArSLID. This included studying gas phase UV spectra of PAH to study ionization, and analyzing soil and sediment extracts with the ArSLID to detect high boiling PAH. Beginning in the fall of 2008, Tim started medical school at Creighton University.

Christine L'Abbe worked during her freshman year in 2005-2006 doing some of the preliminary studies on interfacing the microdialysis extraction probes with a commercial chemiluminescence detector for the analysis of nitric oxide.

Ashley Kramer. Ashley applied microdialysis probes for the analysis of volatile compounds of diagnostic interest. This involved interfacing the gas-phase effluent of the extractions directly into the electron impact source of a mass spectrometer. Ashley currently works for DNA Technologies in Iowa.

Melissa Jones.  Melissa started working early in the fall of 2002. She will be forever acknowledged as the first of a new generation of my students. After helping re-build the lab and getting a new fast GC system running, she began her studies analyzing volatile selenium compounds from foods. The bulk of her work was done characterizing microscale dialysis membrane devices for selective extraction of polar analytes to the gas phase for fast GC monitoring. She graduated in 2006 and, after a short respite as an environmental advocate, is a chemistry graduate student at the U of MN, working with Christy Haynes.

Eric Moeker began working in the summer of 2003, and has characterized the performance of the ArSLID for various fuel samples and compounds, especially in comparison to the PID. He graduated in 2005 and, after working for a year at 3M corporation, entered medical school at the U of MN in the fall of 2007.

Rachel Lundeen began working in the summer of 2004, studying rapid extraction of semivolative compounds from water samples by vaporization of the entire sample and selective removal of water signal. She then spent a year and a half studying environmental analysis in more detail in the Wammer group. After graduation in 2007, Rachel worked for Pace Laboratories and will enter graduate school at the University of Minnesota next year.

Anne Bainbridge began working in the summer of 2004 and continued through the fall of that year. She finished the redisign of our aromatic selective detector, spending countless hours in the machine shop building and rebuilding the electrodes and collectors and studying the effectiveness of the new detector for high boiling aromatic compounds. Anne graduated in 2007 and entered Pharmacy School at the U of MN that fall.

Gregg Schieffer  Gregg joined the group in January, 2003, and has been worked on GC separations with selective detection using an aromatic selective laser ionization detector (ArSLID). He began our groups efforts to redesig the detector to make it more compact, increase sensitivity, and allow high temperature applications. Gregg graduated in 2004 and is currently a graduate student at Iowa State, working first with Ethan Badman. and currently with Sam Houk.

Juliet Hong worked in our lab between the summer of 2003 and the fall of 2004, using GC-MS to study the effectiveness of various sampling apparati for polar VOCs.

Kim Jasch  worked with us in the summer of 2003, using a high-speed GC system to monitor desorption kinetics of VOCs from various sorbents. She graduated in 2006 and is currently a graduate student in mechanical engineering at the University of Colorado.

Tyler Vanaduronvan worked off and on for several years beginning in late 2002, and is the mastermind behind our fast GC programs using LabView. He graduated in 2006 and is currently in the M.D./ Ph. D. program at the U of South Dakota

Jon Maurer. Throughout the 2002-3 academic year, Jon developed software using LabView for data acquisition and instrument control, especially related to high speed pulsed injection systems we are using. He began applying the instruments he built toward sampling studies for polar compounds using various membranes and sorbents, leading to our current work in selective microextraction devices. He graduated in 2006 and is currently working for Take Action Minnesota.

Mark Roberge  Mark was a graduate student who finished his Ph. D. at UND in July, 2003.  His research focussed on the evaluation of a discharge ionization detector for use with portable high speed GC instrumentation.  In addition, Mark worked extensively with collaborators at the USDA on methods for selectively analyzing selenium compounds and applying those methods for physiological studies. After working as a postdoctoral fellow at the USDA in Fargo, ND, Mark took a position at Hollister-Stier in Spokane, WA.

Melissa Meyer  Melissa was a graduate student who finished her Ph. D. at UND in April, 2003.  She studied the effect of various experimental parameters on extraction of VOCs from water.  Optimization of this system allows quantitative extraction of these analytes in 10 - 40 seconds, making it compatible for use with high speed GC.  Melissa also performed the initial experiments in our lab in helping develop the aromatic selective laser ionization detector (ArSLID). She is currently working at PPD (Pharmaceutical Product Development) in Madison, WI.

Travis Falconer  Travis was an undergraduate student at UND who started work in the group after his freshman year in the spring of 1999.  During two summers working with collaborators at Los Alamos, and working at UND one summer and off and on during the school year, Travis worked with membrane introduction mass spectrometry (MIMS).  Specifically, he studied the effectiveness of different types of membrane materials for the analysis of polar analytes such as methanol, and developed a cryofocussing method for improving the detection limits using this technique. Travis is currently a graduate student in analytical chemistry at the University of North Carolina, working first with Roger Miller and, upon Roger's death, joining the group of Gary Glish.

Kevin Dobmeier  Kevin was an undergraduate student at UND who started work in the group during his sophomore year, at the beginning of year 2000.  Working with collaborators at the USDA Human Nutrition Center in Grand Forks, Kevin studied the speciation of selenium in broccoli and other plant tissues.  After beginning with work on LC-ICPMS techniques  to separate and analyze various Se-containing amino acids from their related S-containing compounds, Kevin focussed his attention on analyzing the volatile fraction of Se-compounds in plants.  This information is important given evidence of anti-cancer behavior shown by Se compounds. Kevin, like Travis, attended the University of North Carolina as an analytical chemistry graduate student, working with Mark Schoenfisch and obtaining his Ph. D. in 2007. He currently works at Eisai, Inc., a pharmaceutical company in Research Triangle Park, NC.

Rob Current  Rob was the first graduate student to work in the group, starting in 1996 and finishing in the fall of 1999.  He did the lions share of work setting up much of the lab's equipment early on, and did an excellent job designing and developing the rapid extraction / high speed GC system.  In addition, Rob used high speed GC to monitor the efficiency of a bioreactor for removal of VOCs from a gaseous stream.   Rob has spent his career working for several different instrument companies.

Other former UND students: Mary Gress, Kyle Rasmussen, Rebecca Upham, Steve Hill, Kelli Kuelwein, Beth Mastel, Dawn Schroeder, Brian Kirby
