  • Biography

    Dr. Shashank Sharma Research Assistant Professor Department of Materials Science and Engineering Department of Mechanical Engineering Center for Agile and Adaptive Additive Manufacturing University of North Texas Qualifications: Dr. Sharma holds a joint appointment (50-50) with the Department of Materials Science & Engineering (MTSE) and Department of Mechanical Engineering (ME) at UNT with the primary research activities within the Center for Agile & Adaptive Additive Manufacturing (CAAAM). He completed his integrated MTech and PhD in Mechanical Engineering from one of the premier institutions of engineering, Indian Institute of Technology in Kanpur, India (IIT-K). After completion of his Ph.D. (Jan 2015-March 2020), he joined CAAAM in UNT as Post-Doctoral Research Associate (July 2020-Spet. 2021) followed by Research Scientist (Sept. 2021-August 2022) and became Research Assistant Professor in September 2022. His doctoral work was in the area of laser-based micromachining and numerical modeling/simulation of machining and surface engineering. Since joining CAAAM, the focus of his research activities has widened to laser-and friction stir based additive manufacturing and with an emphasis on computational modelling and simulations of additive manufacturing (AM) process thermokinetics for understanding of material microstructure and phase evolutions and resulting mechanical properties. He is also extensively involved in experimental aspects of AM processes and related in-situ diagnostics and data collection. Due to his involvement in both computational and experimental activities in AM, he is involved multiple projects and hence interacted with serval research colleagues as well as mentored and guided multiple undergraduate, and graduate (MS and PhD) students on their research for senior design projects, theses, and dissertations. He is widely published that included 34 papers in referred journals, three book chapters and he is also a coauthor to a recently published (August 2022) book entitled, Laser-Based Additive Manufacturing: Modeling, Simulation, and Experiments by John Wiley-VCH.
