My research focuses on the intersection of additive manufacturing, materials science, and advanced in-situ characterization. I use in-situ monitoring to study the fundamental physics of additive manufacturing processes, including the formation and evolution of defects (such as spatter, porosity, and cracks), heat and mass transfer, and phase transformations. I am passionate about developing new manufacturing technologies and designing new materials for a wider range of applications, particularly in aerospace, extreme conditions, automotive, energy, and surgery.

Oluwagbemisola, or Gbemi for short, is a Ph.D. student in Mechanical Engineering at the University of Nebraska-Lincoln (UNL). Currently, Gbemi works as a Graduate Research Assistant at Dr. Guo’s lab. Her research focuses on the development of new laser-based additive manufacturing techniques that can create complex and customized parts from various materials. She is particularly interested in applying these techniques to biomedical and aerospace applications.

Gbemi is an active member of several professional societies, including the American Society of Mechanical Engineers (ASME), the Nigerian Institute of Mechanical Engineers (NIMechE), the Young Engineers’ Forum of Nigeria (YEFoN), and the Nigerian Society of Engineers (NSE). Her academic and professional excellence and leadership have earned her multiple awards and recognitions from these societies.

She has a passion for engineering education and industry-academia collaboration in her home country, Nigeria. Gbemi graduated with First Class Honors from Obafemi Awolowo University in Nigeria, where she studied Mechanical Engineering.

In 2019, she co-founded Alo-Timeys Ltd, an organization that provides training and mentorship to engineering undergraduates in Nigeria on engineering design for manufacture and industrial automation. Through this initiative, she has trained over 300 students.

I am a Ph.D. candidate, co-advised by Dr. Jeff Shield and Dr. Qilin Guo in the Department of Mechanical and Materials Engineering at the University of Nebraska–Lincoln. My research focuses on the development and processing of rare-earth magnetic materials, specifically NdFeB-based alloys for laser powder bed fusion (LPBF). These superstrong magnets are essential in technologies such as electric vehicle motors and offshore wind turbines. I work on optimizing powder compositions and processing parameters, and I characterize printed prototypes to study their microstructure and magnetic properties. My research aims to develop feedstock materials tailored for LPBF, using melt spinning as a proxy.

I am from Kingston, Jamaica, and a former student-athlete on the UNL Track and Field team. One of my favorite hobbies is playing tennis. I am currently pursuing a master's degree with a focus on Additive Manufacturing. My research is to develop strategies for additive manufacturing of high-reflective metals. 

Norval is an undergraduate researcher with interests in laser system optimization and alloy design.
