Sagar Nikam is a Lecturer at Ulster University's School of Computing, Engineering and Intelligent Systems, specializing in additive manufacturing and laser processing technologies. He works at the Derry~Londonderry campus in Magee, Northern Ireland. PhD in Engineering from Indian Institute of Technology Indore (2018) MSc from National Institute of Technology Tiruchirappalli (2013) BSc from Shivaji University (2010) His research focuses on additive manufacturing processes , particularly laser directed energy deposition and powder bed fusion technologies. He develops image processing algorithms and computer vision systems for real-time defect detection in biomedical-grade alloys, employing artificial intelligence techniques like YOLO-based object detection models. His work addresses critical aspects such as: Melt pool dynamics and spatter particle analysis Thermal modeling incorporating Marangoni convection effects Finite element simulation of deposition processes Process parameter optimization using genetic algorithms Recent projects include Digital twin-based process monitoring systems funded by the Department for the Economy (UK Government), collaborating with colleagues like Dr. Deepika Nikam, Dr. David Kerr, and Prof. Sean Coleman.
