Biography

Dr. Nagi Naganathan was appointed the Dean of Engineering at The University of Toledo in May 2003. He also served as the Interim Dean between November 2000 and April 2003. Dr. Naganathan is a tenured Professor of Mechanical, Industrial, & Manufacturing Engineering. He has been on the faculty of The University of Toledo since 1986 and also served as the founding Chairperson of the Mechanical, Industrial, & Manufacturing Engineering (MIME) Department between 1995 and 2000. Dr. Naganathan earned a B.E. (Honors) degree in Mechanical Engineering from the National Institute of Technology at Tiruchirappalli (formerly known as Regional Engineering College, Tiruchirappalli), University of Madras, India (1978), a M.S. degree in Mechanical and Industrial Engineering from Clarkson University, New York (1981), and a Ph.D. in Mechanical Engineering from Oklahoma State University (1986). He also serves as the Co-Director of the Dynamic & Smart Systems Research Laboratory at The University of Toledo.

During his administrative tenure, Dr. Naganathan has successfully overseen multiple accreditation visits for the academic programs, secured university and Ohio Board of Regents approvals for a new BS degree in Information Technology (BSIT) jointly with the College of Business Administration and a new PhD degree in Biomedical Engineering jointly with the new UTs College of Medicine, established the first joint research center across the Colleges of Engineering and Medicine in Orthopedics, initiated a university-industry partnership (Senior Design Clinic) to enhance the quality of the capstone design experience for the undergraduate seniors, instituted entrepreneurship and first-year design programs for students, created the Engineering Library in partnership with the UT University Libraries, and founded the Engineering Leadership Institute. Dr. Naganathan also raised donor funds to help the University of Toledo build a new technology commercialization complex (named the Nitschke Technology Commercialization Complex) adjacent to the Engineering education and research facilities to promote entrepreneurial activities among students and faculty.

During his tenure, the College of Engineering has become the venue for several K-12 initiatives such as Math Counts, Math Jets Competition, Girl Scout Camps, etc. Under his leadership, the College of Engineering has continued to elevate the level of excellence of its mandatory co-operative experience program exceeding 14,000 placements in partnership with more than 1,500 employers. In October 2006, for the first time, UTs Engineering Graduate Program was listed among the top 20 graduate programs in the country by Princeton Review. The U.S. News and World Report ranked the UT Engineering Practice Oriented Masters program among the top 50 in the nation.

Dr. Naganathan has proven research expertise in the areas of smart material systems and structures, robotics, and microcomputer applications in electromechanical systems. His current projects include design, analysis, and experimentation for smart material systems and devices involving piezoceramics and magneto-rheological fluids. Sponsors of his research include the National Science Foundation as well as automotive manufacturers. He has secured more than four million dollars through grants to support his research and educational programs. Dr. Naganathan is author of more than 100 publications in peer-reviewed journals and national/international conference proceedings. He has also been awarded a US patent on the use of piezoelectric devices in active suspension systems (US Patent 5,390,949). As the primary graduate advisor, he has supervised 48 masters theses and doctoral dissertations.

Dr. Naganathan is a recipient of multiple awards including the Fellow grade of ASME, The University of Toledo Outstanding Teacher Award, The University of Toledo Outstanding Researcher Award, the SAE Ralph R. Teetor Educational Award, the ASME Outstanding Regional Faculty Advisor Award, the TST/TSPE Engineer of the Year, and the Distinguished Alumnus Award from his alma mater, National Institute of Technology, Tiruchirappalli, India. In January 2003, he was invited to the membership in Rotary International. He currently serves as a Director on the of the ASEE Engineering Deans Council Executive Board, as a member of the Executive Committee of the Board of Directors of the World Association for Cooperative & Work-Integrated Education (WACE), as a member of the Board of Directors of the Ohio Aerospace Institute, and as a member of the Executive Committee of the Council of Energy Research and Education Leaders. As part of his professional experience outside academe, he spent a year with Dana Corporation conducting vibration analysis and control studies on heavy-duty truck powertrains and another year as a Design Engineer with Leyland Motors. He has also served as a consultant for many industries such as Dana Corporation, Eaton Corporation, Teledyne CAE, and others.n

Research Interests

Design, Analysis and Control of Smart Materials Systems

Conventional actuation using kinematic linkages (used as electro-mechanical systems, hydraulic systems, etc.) will not meet requirements of industrial tasks that demand highly precise, yet forceful motions. Actuators made of smart materials such as piezoceramics could logically meet both of the above task requirements. However, regulation of these devices to effect the desired performance has always been a challenging problem, particularly when process requirements exceed simplistic uniaxial motions. Dr. Naganathan and his research group have developed finite element based analytical models that will help to predict the performance of these devices. Additionally, experimental investigations are also being pursued. In the past, these devices have only been used in high frequency micro-actuation (motion ranges of the order of microns in the KHz range). A new class of large stroke, smart material actuators are now being developed at The University of Toledo that are capable of high as well as low frequency motion.  The research group has also conducted extensive work on the use of magnetorheological fluids in vibration isolators.  For more details on current smart systems research, please visit the Dynamics & Smart Systems Laboratory website.

Analysis & Control of Vibrations in Automotive Applications

Vibration issues have always demanded a great deal of attention in automotive applications. With the advent of high torque, low RPM engines, particularly in heavy duty truck applications, the automotive industry is in need of better techniques to model and predict these vibrations. Components whose performances have been taken for granted are once again being revisited for their design and performance adequacy. Dr. Naganathan's research emphasizes torsional vibrations in power trains and the associated rattle problems in gear trains. This research is now being conducted in cooperation with the automotive industry.
