Associate Professor Ahu Çelebi has been serving as a researcher collaborator at University of Toledo and Elahinia Lab. Dr. Çelebi has been a faculty member at Manisa Celal Bayar University in the Department of Metallurgical and Materials Engineering since 2015. In this role, she has significantly contributed to both teaching and research, offering a diverse array of courses, including Additive Manufacturing and Metal Additive Manufacturing through Powder Bed Systems. She completed a PhD in Ceramic Engineering. Beyond her work at Manisa Celal Bayar University, Dr. Çelebi expanded her research horizons by collaborating with the Commonwealth Innovation Center (CSIRO) - Lab 22 in Australia, where she was invited as a visiting scientist from 2018 to 2019. Her primary research focus lies in metal additive manufacturing technologies. Her work predominantly revolves around the exploration of microstructure, mechanical, corrosion and wear properties in Ni-Ti alloys, Ti-Ta alloys, AlSi10Mg alloy, and Inconel series materials, following their production through powder bed systems like SLM (Selective Laser Melting) and EBM (Electron Beam Melting). Moreover, her studies extend to the characterization of glass and ceramic materials by produced additive manufacturing.
My research focuses on the ultrasonic fatigue of NiTi. I completed his Master’s Degree in the summer of 2019, and my research then focused on actuation training and its effects on the actuation fatigue of NiTi-shaped memory wires. I am experienced at following software: SolidWorks, MATLAB, MINITAB and Shimadzu Ultrasonic Fatigue Software (USF)
I am Saeedeh Vanaei, a PhD student in Mechanical engineering at University of Toledo. I have background in materials science and engineering. In my master studies, I worked on the processing and characterization of polymers by conventional (rotational molding) and additive manufacturing (FDM/FFF) techniques. In my PhD studies, I work on additive manufacturing of shape memory alloys (SMAs), and NiTi-based SMAs in particular, for biomedical applications. My focus is on the thermomechanical behavior, microstructure evolution, and texture of SMAs produced by laser powder bed fusion technique.
I completed my M.S. degree under the supervision of Dr. Elahinia at the University of Toledo and am currently pursuing my Ph.D. in his laboratory. My research focuses on sustainable powder engineering and ultrasonic plasma atomization (UPA) of shape memory alloys (SMAs), particularly NiTi, NiTiHf, and NiTiCu systems. I develop circular recycling routes for additive manufacturing feedstock through ultrasonic re-powdering, transforming waste or printed components into high-quality powders. I investigate the effects of remelting and re-atomization on alloy composition, phase transformation, and functional performance using advanced characterization techniques, including DSC, SEM/EDX, XRD, and mechanical testing. My work bridges experimental metallurgy, additive manufacturing, and sustainability, aiming to advance closed-loop manufacturing for the reuse of innovative materials for next-generation energy and biomedical applications.
I am a Ph.D. student in Mechanical Engineering at the University of Toledo. I received both my B.S. and M.S. degrees in Mechanical Engineering, which provided me with a background in materials, manufacturing, and mechanical behavior. My research focuses on additive manufacturing of shape memory alloys, with particular interest in functionally graded materials and architected geometries. I am especially interested in tailoring geometry and material properties to improve energy absorption, mechanical performance, and functional response for advanced engineering applications.
I am a Ph.D. student in Mechanical Engineering at the University of Toledo. My background includes metal forming, thermomechanical processing, microstructure evolution, and the mechanical characterization of metallic materials.

I am a biomedical MS.C. student specializing in additive manufacturing and material characterization, with a focus on shape memory alloys for biomedical applications. In my research at Dr. Elahinia’s lab, I work with laser powder bed fusion (LPBF) on the SLM 280 HL Twin system to fabricate NiTi alloys, optimizing processing parameters to enhance material properties. I also conduct studies on hydrogen embrittlement, examining its effects on the microstructure, strength, and phase transformation behavior of NiTi alloys. With hands-on experience in laser-based 3D printing, electrical discharge machining (EDM), optical microscopy, differential scanning calorimetry (DSC), and microstructural analysis, I actively investigate the relationship between manufacturing processes and material performance, aiming to bridge material science and biomedical innovation to advance medical device technology.
