Barry Allred is a retired Research Agricultural Engineer, having worked 25 years for the U.S. Department of Agriculture (USDA) - Agricultural Research Service (ARS) - Soil Drainage Research Unit in Columbus, Ohio, USA. He is also an Adjunct Assistant Professor in the Food, Agricultural, and Biological Engineering Department at Ohio State University. Prior employment experience includes working as a geophysicist in the petroleum industry (ConocoPhillips Inc.) and as a hydrogeologist with both an environmental consulting firm (ERM-Southwest, Inc.) and a state government agency (New Mexico Bureau of Geology and Mineral Resources). He has a B.S. degree in geology (Oklahoma State University) and two M.S. degrees, the first M.S. with emphasis in geophysics (Northern Illinois University) and the second M.S. with emphasis in hydrogeology (Western Michigan University). His Ph.D. is in Biosystems Engineering from Oklahoma State University. He is a registered professional engineer, a licensed professional geologist, and holds a U.S. Federal Aviation Administration remote pilot certificate. His geophysics research with USDA/ARS has focused largely on agricultural drainage system mapping and golf course infrastructure assessment using both ground-penetrating radar and aerial imagery obtained with drones. He has also studied aspects of soil electrical conductivity measurement using resistivity and electromagnetic induction methods to assess soil properties and transient shallow hydrologic conditions. Other research has involved agricultural water recycling/treatment, soil engineering characteristics, and contaminant transport processes in porous media. This research has resulted in being lead author or co-author of 60 peer-reviewed scientific journal articles along with 50 book chapters, conference proceeding papers, or trade journal articles. He developed the concept and served as lead editor for the first book devoted to the topic of applying near-surface geophysical methods to agriculture (Handbook of Agricultural Geophysics - CRC Press). He has previously served as President of the Environmental and Engineering Geophysical Society, past-Editor-in-Chief of FastTIMES (an online near-surface geophysics news magazine), and is presently Editor for the Ohio Journal of Science (peer reviewed scientific journal of the Ohio Academy of Science). Professional activities have additionally included organization of several symposiums, workshops, short courses, and conference technical sessions related to agricultural geophysics.
