Since joining Purdue, he has been the principal investigator (PI) or Co-PI on 69 research grants with a total budget of $4.75 million from various agencies, including the Air Conditioning and Refrigeration Technology Institute (ARTI), the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), the California Energy Commission (CEC), the Cooling Technologies Research Center (CTRC) at Purdue University, the U.S. Army and U.S. Air Force, and nineteen HVAC&R companies. Since joining Purdue, he has graduated sixteen doctoral students and twenty-five master students. He advised twenty-eight undergraduate project students, twenty-four visiting scholars or visiting research associates, and three post-doctoral researchers. Currently, he advises two Post-Docs, four Ph.D. students, two master students, two undergraduate project students, and three visiting scholars. He has authored or co-authored 58 archival journal articles and 106 conference papers. He has been the co-author of two handbook chapters (ASHRAE Handbook of Refrigeration, one of three authors, and CRC Handbook of Thermal Engineering, one of six authors) and the editor or co-editor of seven conference proceedings. He serves at the Regional Editor for the Americas for the International Journal of Refrigeration. Prof. Groll has organized and chaired the 6th, 7th, 9th and 10th International Refrigeration and Air Conditioning Conferences at Purdue (1996, 1998, 2002 and 2004) and the18th International Compressor Engineering Conference at Purdue (2006). He was General Chair of the 19th International Compressor Engineering Conference and 12th International Refrigeration and Air Conditioning Conference at Purdue (2008). In addition, he has chaired the 4th IIR – Gustav Lorentzen Conference on Natural Working Fluids in 2000 and was Program Co-Chair of the 2003 International Congress of Refrigeration in Washington, D.C. He has organized and chaired several symposia, technical paper, and seminar sessions at ASHRAE and the International Institute of Refrigeration (IIR) conferences. Presently, Professor Groll has also given 38 invited lectures and seminars, and four keynote lectures. Prof. Groll’s achievements in research have been recognized with his naming of Purdue University Faculty Scholar in 2007, the 2003 B.F.S. Schaefer Outstanding Young Faculty Scholar Award, and the 1997 ASHRAE New Investigator Award. His accomplishments in engineering education have been recognized with his induction into Purdue’s Book of Great Teachers in 2008, the 2007 Ruth and Joel Spira Award, his induction as a Fellow of the Purdue Teaching Academy in 2005, the 2005 Charles B. Murphy Award for outstanding undergraduate teaching at Purdue University, the 2004 Team Excellence Award in the Schools of Engineering at Purdue University for outstanding innovation and interdisciplinary teamwork in creating and developing the GEARE program, the 2003 Guest Professorship from the German Academic Exchange Service (DAAD) for his sabbatical stay at the University of Karlsruhe, Germany, his naming as a Senior Resource Faculty for the Teacher for Tomorrow Award Program at Purdue University during the academic year 2002/2003, and the 2002 Solberg Award for best teacher in Mechanical Engineering at Purdue University.
