Dr. Narendra Dahotre is a University Distinguished Research Professor and former Chairman (2010-2013) of the Department of Materials Science and Engineering, University of North Texas (UNT), Denton, Texas, USA. Prior to joining UNT he held a joint faculty appointment with Oak Ridge National Laboratory and the Department of Materials Science and Engineering of the University of Tennessee-Knoxville (2002-2010). Moreover, he was a senior faculty member of the Center for Laser Applications at the University of Tennessee, Space Institute-Tullahoma (1995-20 10). He has been recognized for pioneering contributions to the fundamental understanding and engineering of laser-materials interactions along with the implementation of high power lasers in materials processing and advanced manufacturing with a primary emphasis on surface engineering, additive manufacturing and machining. Dr. Dahotre is internationally known for his work on fundamentals and applications of laser surface engineering of metals, ceramics, composites, and biomaterials and laser machining of ceramics. His research has been extensively funded by the government and industrial organizations including but not limited to Department of Defense, Department of Energy, National Science Foundation.

GM, Ford, Honda, ALCOA, and Babcock & Wilcox. His more than 25 years of experience on laser materials-interactions has been compiled in 3 books as author, and 13 books as editor in the areas of laser materials processing/manufacturing and surface engineering. He has been issued with 15 US patents with 2 more pending, and currently has 243 Publications. He has guided and advised 17 MS students, 15 PhD students, and 10 post-doctoral fellows. Additionally, he is fellow of the World Innovation Foundation (2014), National Academy of Inventors (2013), Materials Research Society India (2011), Society of Manufacturing Engineers (2010), American Association of Advancement of Science (2009), Indian Institute of Metals (2009), American Society for Mechanical Engineers (2008), and the American Society for Metals International (2004). He is the Editor-in-Chief of the International Journal of Additive and Subtractive Materials Manufacturing and currently serves on 8 editorial boards of refereed journals in the area of materials science and engineering. Sameehan Joshi completed his master's degree in Materials Engineering in 2012 from the Indian Institute of Science, Banaglore, India after completion of a bachelor's in Metallurgical Engineering from the College of Engineering, University of Pune, India. His research is focused on the development of cast magnesium alloys.

He worked as a research engineer in the automobile industry for a year and half before joining the University of North Texas in 2012, where he is enrolled on a PhD program at the Department of Materials Science and Engineering. His research here is focused on the mechanical behavior of laser processed metallic glasses. His research interests include amorphous metallic materials, light metals and alloys, high entropy alloys and bio materials. To date he has published 5 journal papers and a conference proceeding.
