Bio<\/span><\/strong><\/h4>\r\n

Dr. Andrew C. Hillier is a Professor and the Reginald R. Baxter Endowed Department Chair of the Department of Chemical and Biological Engineering at Iowa State University. He earned his B.S. in Chemical Engineering from the University of Nebraska in 1990 and his Ph.D. in Chemical Engineering from the University of Minnesota in 1995, where he worked with Professor Michael D. Ward. He then completed a postdoctoral appointment at the University of Texas at Austin in the laboratory of Professor Allen J. Bard.<\/p>\r\n

Dr. Hillier began his academic career at the University of Virginia, where he became an Associate Professor in the Department of Chemical Engineering and was a member of the Center for Electrochemical Science and Engineering. In 2003, he joined Iowa State University, with faculty appointments in Chemical and Biological Engineering and Chemistry. During his time at Iowa State, he has held several leadership and research roles, including Associate Scientist with Ames Laboratory and Director of the W.M. Keck Laboratory for High Throughput Atom Scale Analysis. He began serving as Chair of the Department of Chemical and Biological Engineering in 2013.<\/p>\r\nThroughout his career, Dr. Hillier has received numerous honors, including the Camille and Henry Dreyfus New Faculty Award, a National Science Foundation CAREER Award, and Young Investigator Awards from the Office of Naval Research and the Society of Electroanalytical Chemistry. He is a Fellow of both the American Association for the Advancement of Science and the American Institute of Chemical Engineers.\r\n

Interest Areas<\/h3>\r\n

Dr. Hillier\u2019s research focuses on the experimental and modeling aspects of interfacial processes, with particular emphasis on the optical and electrochemical properties of thin films and coatings. His work involves the development and application of surface fabrication, analysis, and characterization techniques to create nanostructured surfaces for plasmonic sensors and diffractive optical elements, as well as metal films and nanoparticle coatings for electrocatalytic applications, including fuel cells, electrochemical synthesis, and chemical conversion.<\/p>\r\n

His research also examines model surfaces to better understand surface structure, stability, functionalization, and reactivity. His group employs fabrication methods such as sputter coating, thermal evaporation, laser lithography, electrodeposition, and spin coating, along with characterization techniques including atomic force microscopy, ellipsometry, electron microscopy, electrochemical mass spectrometry, atom probe tomography, optical microscopy, and visible and infrared spectroscopy.<\/p>\r\nCurrent research areas include nanostructured surfaces for plasmonic and guided-mode optical sensing, electrocatalytic systems and in-situ reaction pathway analysis, nanostructure-enhanced visible and infrared spectroscopy, and nanoscale surface fabrication through optical and electrochemical coupling.\r\n\r\n<\/div>\r\n
