Jean-Christophe “Geff” Geffard

Principal Engineer,
ATAC

Geff has been providing Aeronautics and Electronics Systems engineering expertise for 35+ years. He is currently a principal engineer with ATAC corp. supporting FAA safety and data management programs for multiple groups including VFAST, CASSIE, RDOE, EIM, HPC and Separation Standards.

Grant Morfitt

General Engineer,
FAA

Grant is with the Aviation Research Division, Software and Systems Branch, System Safety Section. He graduated from Rowan University with his MS in Electrical and Computer Engineering in 2021. He has been with the agency for five years following a co-op internship while pursuing his degree, during which time he supported the school’s Virtual Reality Lab and associated FAA research. Grant currently supports multiple areas within the FAA which are primarily focused in the areas of Terminal Area Safety (TAS) and Rotorcraft Safety initiatives. He is currently leading a project within TAS focused on the impact of immersive technologies on pilot training, and he supports the rotorcraft safety group with human in the loop experiment design, data analysis, documentation, and system integration.

EIT

Maggie is a commercial pilot with instrument rating and experience as an F-16 Avionics Technician. She has a B.S. in Physics from Rowan University and is currently pursuing a master’s in Industrial Engineering at Iowa University, focusing on human factors and flight test engineering. Dedicated AvSTEM ambassador and aviation enthusiast.

Tim Kuhn

General Engineer,
FAA

Tim graduated with a B.S. in Electrical and Computer Engineering in 2019. He is with the Software and Systems Branch of the Aviation Research Division. He started with the FAA in their Gateways Internship Program and converted to full-time work with the team just last year. Currently, his focus is on developing cyber capabilities for the VFAST simulators and supporting their operation across a variety of research studies.

Andres Geffard

Biomedical Engineer,
ATAC

Andres is a rotorcraft safety research engineer with ATAC. He graduated from Rowan University with a B.S in biomedical engineering and is now a part-time biomedical engineering graduate student at Johns Hopkins University. At VFAST, he maintains and enhances flight simulators, conducts data analysis, develops the website, and designs custom parts and materials using CAD and additive manufacturing technology.

Partners & Collaborators

FAA Cockpit Simulation Facility

The CSF Team operates a set of high-fidelity aircraft simulators for human-in-the-loop research studies. Their simulators combine in-house developed software and hardware along with actual aircraft avionics, which provides very high fidelity in the simulation and at the same allows us to customize our simulators based on a customer’s unique requirements. This gives the ability to assist clients in their simulation goals, scenario development, and data collection. The CSF has supported various projects such as workload assessments, new integrated avionics, and weather technology in the cockpit.
