Jutima Simsiriwong, Ph.D.

Dr. Jutima is an Assistant Professor of Mechanical Engineering in the School of Engineering in the College of Computing, Engineering, and Construction at the University of North Florida (UNF). Prior to joining UNF in 2018, she was a Visiting Assistant Professor in the Department of Mechanical Engineering and the Laboratory for Fatigue and Additive Manufacturing Excellence (FAME) at Auburn University. She received her Ph.D. in Aerospace Engineering from Mississippi State University in 2014.

Her research background is in fatigue, failure analysis, additive manufacturing, and mechanical behavior of materials including metallic and polymer-based materials.


Palmer Frye (M.S. Student)

Palmer is pursuing a Master of Science degree in Mechanical Engineering at UNF. Currently, Palmer is assiting in the investigation of the mechanical behavior of laser beam powder bed fused Inconel 718 under cyclic loading. This research utilizes a Shimadzu USF-2000A ultrasonic fatigue test system to determine the influence of additive manufacturing process induced defects on fatigue crack initiation. Palmer hopes that his research efforts will lead to the aerospace industry’s adoption of additive manufacturing techniques for full scale production of critical components that already utilize nickel-based super alloys such as Inconel 718.

Andrew Miceli (BSME Student)

Andrew is a junior  majoring in Mechanical Engineering at UNF.  He is currently investigating the corrosion-fatigue  behavior of the biocompatible metallic materials. Specifically, his experiements involve  the heat treatment and surface effects on Ti-6Al-4V in corrosive environments. He ultilizes  the uniaxial fatigue test set up to test this material while bathed in a corrosive saline environment to resemble internal human environment scenarios.

Andrew is  interested in the medical subsection of engineering and would love to transition into Biomedical Engineering for further research beyond his current studies. After this research is completed, he hopes to gain an understanding of the Quality Engineering involved in medical engineering. He is looking to move into development of medical devices in his future and as such this research is highly specific to what he is looking to move towards post-graduation.

Jade Welsh (BSME Student)

Jade is currently a master’s student in the Master of Science degree program in Materials Science and Engineering at UNF. He is investigating the inert gas effects on the microstructure and very high cycle fatigue behavior of AM 17-4PH stainless steel. Jade is aspiring to work in the biomedical engineering industry after graduating in order to improve skills in design and quality control.

Juan Fernado Bedoya (BSME Student)

Fernado is a senior Mechanical Engineering student at UNF. He works in the Fatigue Research Laboratory as an assistant in the research of the corrosion-fatigue behavior of biocompatible materials. His primary project consists of studying the effect that high frequency laser etching has on the fatigue life of 316L Stainless Steel in a corrosive environment.

His interests are in Aerospace, Stress Engineering, and Mechanical Design. After completing his Bachelor of Science, he intends to pursue a master’s degree in the stress analysis of aerospace systems. He is also a proud member of the Hispanic community in STEM. He is currently serving as chapter president of the Society of Hispanic Professional Engineers at UNF. This organization has allowed him to be meet and network with great individuals. Eventually, he would like to become a leader in STEM and serve this community by practicing engineering.

Raymond “Andy” Kapperman 

Raymond “Andy” Kapperman is a senior Mechanical Engineering student at UNF. To help understand how corrosion impacts the performance and lifetime of materials, Andy is assisting with research meant to analyze the behavior of Ti-6Al-4V in highly corrosive environments like the human body. The study will especially apply to the use of Ti-6Al-4V for biomedical implants.

After graduating from UNF, Andy plans to pursue a Master’s in Astronautical Engineering. His engineering interests are centered on understanding how materials and machines operate in the most extreme environments like the human body, outer space, and the ocean. Andy is also involved in other research projects aimed to generate electricity from ocean waves. Whenever he is not studying or conducting research, Andy can be found producing his own STEM podcast The Spoondrift, reading, or taking long walks outdoors.
