Faculty and Staff

Jack Stubbs


Jack is the founding Director of the Prototype Development and 3D Print Lab at the University of Central Florida’s Institute for Simulation and Training. His focus is developing new approaches and uses of technology to simulate and teach healthcare interactions and procedures. Technology and techniques he specializes in are rapid prototyping, 3D printing, and additive manufacturing to improve designs, create prototypes and test devices. Additionally, he deploys this knowledge to implement a cost-effective development model.

Previous to this, he spent a number of years at the University of Minnesota Medical School conducting similar research. In an earlier venture, Mr. Stubbs started a research and development company which created the intellectual property which resulted in over 50 patents, including the Airseal trocar for laparoscopic surgery which is now the trocar of choice for robotic surgery having been used in over 700,000 surgeries globally. He led this company from its founding in 1996 until its sale in 2010.

Dr. Christine Allen

Principal Scientist

As a specialist in human factors and usability, Christine evaluates early prototypes. She is an Assistant Professor and mentors to first and second-year medical students with UCF College of Medicine’s Focused Inquiry Research Experience. Previously, she worked as a Science and Technology Manager with the Army Research Laboratory-Human Research and Engineering Directorate from 2008-2015 in medical simulation research and program development, coordinating with military medical facilities to create training modalities addressing gaps in operational readiness. Christine leads an active Florida lifestyle while maintaining interests in gardening and photography. Such, activities allow her to foster insightful perspectives for her work at PD3D Lab. Additionally, she helped develop and transition multiple research training technologies to military programs of record, authored numerous papers and presentations. She received her Ph.D. in Modeling and Simulation from UCF.

Dr. Lori C. Walters

Research Associate Professor

Lori is the director of the ChronoPoints laser scanning initiative at the Institute for Simulation and Training (IST) here at the University of Central Florida. As a public historian and social researcher who utilizes laser scanning extensively in her research, she works closely with the PD3D team on a variety of laser and structured light scanning projects as well as the application of 3D printing to historic structures and artifacts. She is the recipient of support from the National Endowment for the Humanities, National Science Foundation, Army Research Lab, Microsoft, and State of Florida Bureau of Historic Preservation. Lori can never resist working on any project that addresses an aspect of Mid-Century architecture and design and is known to obsess about one amazing Mid-Century building, the Cocoa Beach Glass Bank.

Dr. Michael Xynidis

Postdoctoral Scientist

Michael’s eclectic background, in Applied Mathematics (BA, emphasis Computer Science), as an IBM trained System Engineer, as a Ph.D. in Modeling and Simulation and previously serving as a Firefighter/Paramedic gives him insight into a wide array of challenges. He enjoys custom product conceptualization, design, and prototyping, for wide-ranging applications including military and medical. Additionally, he mentors students working at PD3D. Michael is a published author and speaker, who is affiliated with several industry organizations and has knowledge of marketing and business analysis activities.

Jim Inziello

Director of Generative Design

As a lifelong Floridian, Jim spent his formative years enjoying boating and interacting with sea life in his family’s boat business. This endowed him a work ethic, craft skills and attention to detail that has allowed him to master many other disciplines, like sculpture, material casting, 3d modeling, painting, and technical art. He is a 3D Artist and an avid Futurist, a background he has used for over 21 years in the exhibits, video game, and training industries. Jim has extended this knowledge and passion into 3D printing the past 6 years. If there is a new design revolution on the horizon, he will be at the vanguard of that revolution.
