Dr. N. Lakshmi Narasimhan started his career as a Mechanical Engineer, graduated from RVS College of Engineering and Technology, Dindigul (affiliated to Madurai Kamaraj University), in the year 1995. He obtained his Masters degree M.S. (By Research) from AnnaUniversity during 2000 for his research work on Latent Heat Thermal Energy Storage. Later, he pursued Ph.D. at IIT Madras (2006-2010) and carried out research in the area of Cryogenics, specializing in cryogenic mixed refrigerant technology. In his Ph.D. work, he studied the variation of composition of mixed refrigerants during circulation in a Joule-Thomson refrigerator operating at cryogenic temperatures and came out with relationships that can be used to estimate the charge composition of a particular mixture. To his credit, he has a teaching experience of about 17+ years and has published about 12 technical papers in refereed international Journals and 12 International Conference papers. He is actively engaged in carrying out funded Research Projects and Joint Industrial Consultancy projects. As a department faculty placement coordinator since 2010, he has been interacting with industries through consultancy, active MOUs, student placements, internships and joint research.
