D Raman



  • Higher Ed: Engineering, Higher Ed: Administrator, Researcher 


Dave Raj Raman is Professor and Associate Chair for Teaching in the Agricultural and Biosystems Engineering (ABE) Department at Iowa State University, where he is also University Education Program Director and Testbed Champion for the NSF Engineering Research Center for Biorenewable Chemicals (CBiRC), Director of Graduate Education for the Interdepartmental Graduate Minor in Biorenewable Chemicals, and Education Programs Co-Leader for the USDA-AFRI project CenUSA Sustainable Production and Distribution of Biofuels for the Central USA. He is a licensed Professional Engineer who earned his BS in Electrical Engineering from the Rochester Institute of Technology and his PhD in Agricultural and Biological Engineering from Cornell University. Prior to coming to Iowa State in 2006, he was a faculty member at the University of Tennessee for over twelve years.

Raman enjoys teaching and has taught courses including freshmen engineering (mechanics and computer programming to classes ranging in size from 20 to 500+), sophomore and junior level courses on mass and energy balance applications to biological systems engineering, numerical methods, electric power and electronics for technology students, senior design, as well as a long-standing residential/online graduate course on the fundamentals of biorenewable resources and technology. He believes well trained, curious, thoughtful people are crucial to a universitys research effort, and similarly to the function and survival of society. For this reason, the overarching goal of his teaching is to impart the core content needed by the students, and to do so while encouraging inquisition and higher levels of thought. He has secured competitive funds to support his teaching efforts from university, industry, and federal sources and for his efforts has received departmental, college, and national teaching honors including the Farrall Young Educator Award given by the American Society of Agricultural Engineers, and an invitation to participate in the National Academy of Engineerings 2013 Frontiers in Engineering Education Conference.

Raman chairs the ABE Engineering Curriculum Committee and in that role oversaw the successful 2012 ABET accreditation visit for both the Agricultural Engineering (AE) and Biological Systems Engineering (BSE) degree programs. Upon arriving at ISU in 2006, he led the development of the BSE program, and this program now enrolls over 80 students. Raman also runs multiple summer research internship programs through his roles in CBiRC and CenUSA. In his role as Pyrone Testbed Champion for CBiRC, Raman and his students have developed early-stage technoeconomic models of bioprocessing systems. His graduate students have gone on to faculty positions at Purdue and the University of Georgia, and to engineering leadership positions at companies including Cargill, Nestle, and Merck.
