Dr. Renfu Lu has been a research agricultural engineer with U.S. Department of Agricultural Research Service (USDA-ARS) since 1994. He served as Research Leader for the USDA-ARS research unit at Michigan State University since 2007 and location coordinator since 2015. Prior to joining USDA-ARS, he was a research assistant professor (1994) and research associate (1990-1993) with the Department of Biological and Agricultural Engineering at University of Arkansas. As an adjunct faculty since 1999, Dr. Lu has supervised and mentored graduate students in the MSU Biosystems Engineering.
Lu currently leads a research team to develop an innovative robotic technology for automated harvesting of apples and a new generation of imaging technology with enhanced capabilities for quality inspection of fruits and vegetables during postharvest handling. He has made many original contributions in the development and application of acoustics, near-infrared spectroscopy, hyperspectral imaging, light scattering, mechanical and optical property measurement, structured-light imaging, and apple robotic harvesting and infield sorting technologies. He has authored or co-authored 141 peer-reviewed journal papers, 17 book chapters, 105 conference proceeding papers and 33 other publications (as of April 2021). Lu has edited two technical books and served as a guest editor for three special issues for two international journals. He has held numerous leadership positions with the American Society of Agricultural and Biological Engineers (ASABE), including chair of Publications Council (2016-2018), Refereed Publications Committee (2014-2016), and Food and Process Engineering Division (2012-2013). He has served as an editor (2009-2015) and associate editor (2002-2009) for Transactions of the ASABE and the journal of Applied Engineering in Agriculture, and on the editorial board of two international journals.
