Home: Badulla, Sri Lanka

Research Interests: Nitric oxide involves in many important biological functions including vesodilation, immune response and neurotransmission. Disruption to the balance of NO production causes cardiovascular and neurodegenerative diseases. This can happen due to cellular heterogeneity under various chemical and physical stresses occur inside the body. Therefore, the main goal of Dulan’s project is to determine nitric oxide and other reactive nitrogen species release with response to various endotoxins, cytokine and other stimulating agents in bulk and single cell level. To achieve this goal Dulan is working on a separation based approach using a microchip electrophoresis coupled to in-channel electrochemical detection set up.

Dulan is a huge fan of Sri Lankan Cricket team and play Cricket whenever he has a chance. Also, Dulan fell in love with Jayhawk basketball and since then he is trying to play basketball.

Home: Glenview, IL

Research Interests: Tom’s project is to develop an analytical method to measure the concentrations of a class of compounds from blood serum that have been implicated in cardiovascular disease. To this end, he optimized a procedure to rapidly isolate these species from serum samples and then determined their concentrations using both capillary and microchip electrophoresis. The ultimate goal of his project is to measure the endogenous concentrations of these biomarkers in patients with and without coronary atherosclerosis to establish a threshold level that could be utilized to preventatively diagnose heart disease.
Tom is working on finishing his Ph.D. and is interested in expanding his skill-set by obtaining a postdoctoral research position after he graduates. His long-term career goal is to become a research professor although he would also be amenable to managing a research lab in industry.

In the rare occasions Tom is not in lab, he is probably either out playing softball or trivia.

Home: Palmeira dos Indios, Alagoas, Brazil

Research Interests: Diogenes is currently developing a PhD project in cooperation with the Group Susan Lunte, University of Kansas and the Group Alberto Fracassi (Co-advisor), University of Campinas, working with development of analytical methodology for detection of reactive species nitrogen and oxygen, for it uses to electrophoresis coupled microdevices as a technique for separation and electrochemical detection technique, which aims to reduce noise, separate the species by improving their detection, diminur the limit of detection, among others. Diogenes worked on his master's degree with the development of analytical methodology for preconcentration and determination of heavy metals in water with UV detection coupled to flow injection analysis (FIA).

Nate Oborny
Biotech Training Grant Recipient 2011
2010 B.S. Genetics, University of Kansas
2002 B.S. Computer Engineering, University of Kansas
noborny@ku.edu

Home: Lawrence , KS

Research Interests: Nathan's research focuses on the design and construction of integrated data acquisition systems for use with microfluidic sensors. One of the primary focuses of the Lunte group is the identification of analytes through on-chip electrophoretic separations. The use of these methods represents a powerful laboratory technique. However, the need for high voltage power supplies and large detection systems negate the many of the miniaturization benefits of using a microfluidic device. By using a combination of off the shelf, open-source hardware as well as custom built solutions, Nathan's goal is to make on-chip separation technologies more useful in the field and as point-of-care diagnostic options.

Nathan's personal interests include electronics projects, gardening, camping, and spending time with family/friends/dog.

Simon Pfeiffer
2011 B.S. Chemistry, University of Regensburg, Germany
International Scholar, Regensburg University, Germany
pfeiffersimon@ku.edu

Home: Schongau, Bavaria, Germany

Research Interests: Simon's research is mainly concerned with microchip electrophoresis utilizing fluorescence detection. In his project he is working on the separation optimization for amino acid neurotransmitters and on protocols for the reliable long term operation of microchips. In the future these results will be used for in-vivo studies relating to neuronal activity and brain damage during stroke.

Apart from lab work, Simon enjoys pocking around with computers and tech in general. He has also transformed into a big Jayhawk basketball fan, although he is normally more of a soccer person.

Home: Missoula, MT

Research Interests: Anne is developing microfluidic platforms for electrochemical sensors coupled to microdialysis sampling. Currently, she is working on integrating carbon electrodes into polymers and developing an interface for microchip electrophoresis and microdialysis sampling.

When not in lab, Anne enjoys finding interesting recipes to try out and reading science fiction.

Rachel Saylor
2010 Honors BS Chemistry, Wittenberg University
rsaylor@ku.edu

Home: Metamora, OH

Research Interests: With interests in both analytical chemistry and neuroscience, Rachel is fortunate enough to work in both of these disciplines as part of the lab on a sheep project.  As part of this project, Rachel is developing a system which uses microchip electrophoresis and electrochemical detection to separate and detect catecholamines present in brain microdialysate.  The entire analytical platform and associated instrumentation will be contained in a backpack worn by a sheep, for the first near real time correlation of behavior to catecholamine concentration in freely-roaming animals.

In her free time Rachel enjoys reading, running, randomly dancing, and ballet.

Home: St. Louis, Missouri

Research Interests: Joe’s research project focuses on measuring the peroxynitrite production in a single cell using microchip electrophoresis coupled to laser induced fluorescence detection. With this technology, the heterogeneity of cellular phenotypes can be studied. These results will allow for a better understanding of neurodegenerative and cardiovascular diseases.

Outside of the lab, Joe enjoys playing sports, reading, and hanging out with friends.

David Scott
2000-2004 USMC
2005-2008 B.S. Biochemistry, Rockhurst University
scottde@ku.edu

Home: Sullivan Missouri

Research Interests: David's research has primarily focused on the fabrication and method development of bonding procedures for glass microdialysis-microchip electrophoresis (MD-MCE) systems and integrating metal electrodes into the microfluidic microchips using a DC magnetron sputtering source. With this, David is now focusing on developing a miniaturized microdialysis-microchip electrophoresis (MD-ME) system designed for the continuous in vivo monitoring of biogenic amines and reactive oxygen species is being developed. The system is being optimized for the continuous on-line analysis of microdialysis samples obtained using submicroliter flow rates to increase analyte recovery and temporal resolution. The ultimate goal is to perform quantitative microdialysis on-animal with minimal time delay between the biological event and the detection of the event in order to correlate learning and behavior.

Outside of the lab David enjoys snowboarding, "zen and the art of motorcycle maintenance", and weight lifting/running.
