Dr. Tuğrul Özel's research programs focus on advanced manufacturing, additive manufacturing, precision machining, laser materials processing, computational modeling and optimization of advanced manufacturing processes, and development of innovative micro/nano devices, processes, and integrated manufacturing systems. Dr. Özel has established an internationally recognized research program in the precision machining and additive manufacturing of advanced materials including alloy steels, titanium, and nickel-based superalloys. His other work has focused on laser processing of polymers and ceramic materials for microfluidics and microelectronics applications, micro-manufacturing of polymer microneedles for biomedical device applications, and most recently metal additive manufacturing method called laser powder bed fusion of nickel-based superalloys for aerospace applications. He is also interested in research on 3D bioprinting of natural fibers, bio composites, alginate, collagen and other sustainable materials for tissue and biomass constructs.

Dr. Özel has published four edited books; Intelligent Machining (2009), Micromanufacturing: Design and Manufacturing of Micro-Products (2011), Biomedical Devices: Design, Prototyping and Manufacturing (2016), and most recently, Modern Manufacturing Processes (2019). He published over 150 articles in leading engineering journals and conferences. His journal articles received high number of citations (over 9,000) and his current author h-index is 27 in SCI-Web of Science, 36 in SCOPUS, and 46 in Google Scholar databases. He has been on the scientific committee of over 50 international conferences, chaired numerous conference sessions, delivered 60 conference presentations, keynote and planetary papers. He is the editor-in-chief of the International Journal of Mechatronics and Manufacturing Systems, Associate Editor of ASME Journal of Manufacturing Science and Engineering, Editorial Board Member of The International Journal of Machine Tools and Manufacture, and Production Engineering, Research and Development.

Dr. Özel's research has been well funded (over $1.2 million as sole or lead-PI) by the National Science Foundation, Department of Commerce-NIST, TK Tribology Research Foundation NASA/New Jersey Space Grant Consortium, and industry. Current research projects include surface quality and material property investigations in additively fabricated products using laser powder bed fusion, precision/micro-machining of advanced metal alloys using micro-textured tooling, predictive modeling of machining induced surface integrity, laser materials processing of polymers and semi-conductor materials and computational modeling and optimization of manufacturing processes using finite element method and machine learning. He has graduated 6 Ph.D. and 22 Masters students, and supervised 20 visiting PhD or Masters students, and 10 Aresty Research assistants, and many undergraduate student projects in these research areas.

Dr. Özel is a senior member of SME, ASME, NAMRI and former Associate Member of CIRP-International Academy for Production Engineering.
