July 25, 2018

Personnel changes within the Lowell Institute for Mineral resources:

On behalf of the leadership team of the Lowell Institute for Mineral Resources, I am pleased to announce the return of Dr. Mary Poulton as Co-Director, effective July 1, 2018. Dr. Poulton previously served as Director of the Lowell Institute from 2009 to 2017, and subsequently on the Board of Directors as Co-Chair. Dr. Poulton brings with her 30 years of experience as a distinguished professor in mining and geological engineering, and was the first woman to head an engineering department in the history of the University of Arizona. She is also a co-founder of three technology startup companies. I will continue to serve as Co-Director.

Dr. Brad Ross, who served as Co-Director from 2017 to 2018, will assume the position of Director, Geotechnical Center of Excellence. Dr. Ross is currently a Professor of Practice with UA's Mining and Geological Engineering and brings with him more than 40 years of industry experience. His experience has included a variety of positions ranging from Technical Services Manager, Operations Engineer, Financial Controller, to Asset Manager and Training Manager. His last position in industry was to manage the technical teams at the Bingham Canyon Mine before and after the massive Manefay landslide in 2013.

Joining Dr. Ross as Assistant Director, Geotechnical Center of Excellence, is Chad Williams. Chad will assume his new role effective August 13, 2018. Chad has a Bachelor of Science Degree in Mining Engineering and a Master of Science in Geotechnical Engineering from Virginia Polytechnic Institute.  Chad also has over six years of experience working at the Bingham Canyon Mine for Rio Tinto where he managed the geotechnical studies after the Manefay landslide.  Most recently, he has been Geotechnical Engineering Superintendent for the mine where he and his team have implemented innovative methods of pit monitoring, geotechnical analysis, pit slope management, and rock fall protection.

Dr. Isabel Barton will be moving from her role as research scientist with the Lowell Institute to become Assistant Professor in Mining and Geological Engineering. Among other Institute activities, she created and led the interdisciplinary Geometallurgy program and she led development of the Lowell Institute's highly successful "Integrated Inputs to Mine Planning" continuing education series. We will miss having Isabel within the Institute but look forward to working together as she takes on her new role.

As part of the continued development of the Lowell Institute, Jodi Banta, will become Program Manager reflecting her multiple roles and responsibilities in managing Institute activities. Jodi joined the Institute in December 2017 as Senior Program Coordinator after more than a decade in the financial services industry, principally with AIA Group. Jodi holds a Bachelor of Arts degree in Sociology from the University of Arizona.

Additionally, Molly Radwany recently joined the Lowell Institute as Education Outreach Coordinator effective July 1, 2018. Molly holds a Bachelor of Science in Geology and Geography from George Washington University, and a Master of Science in Earth Science from the University of Minnesota. She will be working closely with Pam Wilkinson, who has served in this role since 2009 having worked previously with the Arizona Department of Mines; Pam will be retiring at the end of March 2019. We wish Molly (and Pam) the very best in their new roles!

Please help me to welcome our new staff.
