Dr. John Haan, Chemistry

Education and Professional Positions

Ph.D., Analytical Chemistry, University of Illinois, Urbana, IL, 2010
M.S., Chemical Education, University of Florida, Gainesville, FL, 2005
B.S., Materials Science & Engineering, University of Wisconsin, Madison, WI, 1999

Current Research Interests

The research in Dr. Haan’s lab is centered on using electrochemistry to solve energy and sensing challenges with applications in biomedicine, environmental science, and alternative energy.  The lab has developed a formate fuel cell that coverts potassium formate and air to energy in a manner more efficient than alcohol fuel cells.  The lab has also developed a device that converts dissolved carbon dioxide to formate that can then be converted into energy when needed; students are presently working to optimize this device.  Dr. Haan has an existing collaboration with Drs. Su Ha and Louis Scudiero at Washington State University in which the labs work together to develop and characterize metal catalysts that improve the efficiency of biofuel conversion to energy.  Dr. Haan also has a collaboration with Dr. Frank Gomez at California State University, Los Angeles, in which the labs have worked together to develop the first formate fuel cell on paper.  This fuel cell is designed to provide energy for paper microfluidic sensing devices with biomedical and environmental applications; students are presently working to optimize the fuel cell and develop new, paper-based sensors.
