"Research Scientist"

The Ohio State University, College of Engineering, Department of Materials Science and Engineering, is seeking a Research Scientist.

Minimum Required Education is a PhD in Mechanical, Welding, Metallurgy, Materials Engineering, or a similar field. Candidate must have 7-11 years of relevant research experience with 10-15 years preferred.

The Research Scientist should be fully experienced in a Research Laboratory environment, serving as a resource for Research Technicians, Graduate Research Associates, Undergraduate Research Assistants, and Undergraduate Students. They will apply industry knowledge to lead research, work independently on complex projects, and complete routine work with general guidance on new initiatives.

Specific research areas include development of materials joining processes and metal additive manufacturing, process automation, and materials analysis for advanced materials. Required experience includes comprehensive knowledge in welding research such as advanced welding processes, metallurgical analysis, and process/materials simulation and modeling.

From the welding process perspective, experience includes Gas Metal Arc Welding (GMAW) variations like Pulsed current, Controlled short circuit, Cold Metal Transfer (CMT), Surface Tension Transfer (STT), Regulated Metal Deposition (RMD), Controlled Carbon and Carbon Dioxide (CCC), and High-performance GMAW; Gas Tungsten Arc Welding (GTAW) with Pulsed current and dynamic wire feeding; Plasma Arc Welding (PAW); Friction Stir Welding; High-Speed filming; acquisition and interpretation of welding signals; and offline programming for additive manufacturing in 6-axis robots.

Welding metallurgy and materials science expertise includes metallographic sample preparation for steels, stainless steels, Ni-based alloys, Ti alloys, Al alloys, and refractory alloys; optical microscopy; scanning electron microscopy with Energy-dispersive X-ray spectroscopy (EDS), Electron Backscatter Diffraction (EBSD), and prior grain reconstruction; corrosion testing; Charpy impact testing; and hardness testing including macro, micro, and nano-indentation.

Modeling experience should include Finite Element Method (FEM), Computational Fluid Dynamics (CFD), and Calculation of Phase Diagrams (CALPHAD), with proficiency in software like SolidWorks, Simufact, Thermo-Calc, COMSOL, Abaqus, SysWeld, and PowerMill.

The Research Scientist will be involved in laboratory work on materials joining processes, materials testing and analysis (e.g., optical and electron microscopy, chemical analyses, indentation, tensile testing, CVN, Diffusible Hydrogen, Thermo-mechanical simulation); simulation and modeling (e.g., FEM, fluid flow simulations, CALPHAD); seeking R&D funding and preparing proposals; supporting research work of staff and students; writing scientific reports and papers; and teaching arc welding processes classes.
