Andy Nelson earned a B.A. in biochemistry from the University of Colorado in 2009 and an M.S. in environmental engineering from the Colorado School of Mines in 2010. As a research assistant in the Department of Molecular, Cellular, and Developmental Biology (MCDB) at the University of Colorado, Mr. Nelson studied free radical signaling mechanisms relevant in aging and tumor progression. In 2012, Andy was awarded the University of Iowa Presidential Graduate Fellowship to pursue a PhD in the Interdisciplinary Human Toxicology Program. He is currently a doctoral candidate under the mentorship of Dr. Schultz, with whom he studies radioactivity associated with unconventional drilling (hydraulic fracturing and horizontal drilling) of shale gas. Much of Mr. Nelson’s work to date has focused on developing methods that are suitable for monitoring levels of naturally occurring radioactive materials (NORM) present in wastes generated by unconventional natural gas exploration. Andy’s research has helped develop partitioning models that will be used in the development of sound waste management strategies for solid and liquid wastes generated by unconventional drilling.
