First and foremost, its an honor and pleasure to join you all here in the VFS Open Forum.

I first became passionate about the concept of eVTOL aircraft when I first became an eVTOL Researcher 10 years ago.

Growing up, I was the youngest pilot at my airfield, which was located just outside of Philadelphia Pennsylvania, where I learned to fly Piper Cherokee 140 fixed wing aircraft at the age of 12. Next, I learned to fly rotary wing aircraft at the age of 21, focusing on the Schweizer 300 and Airbus A-Star airframes.

In 2019, I became the Chief Executive Officer of aeroG Aviation, which is one of many eVTOL design companies. While at aeroG, I developed a passion for eVTOL flight simulation and personally funded the creation of the aeroG aG-4 Liberty eVTOL for X-Plane 11, which was the first eVTOL ever commercially developed and sold to hobbyists and future eVTOL pilots, using the X-Plane 11 flight simulation platform.

In May of 2021, I created and founded eSIM, which stands for eVTOL Simulation Pilot Training. eSim

As the Founder and Chief Executive Officer of eSim, it is my goal to create a foundational educational standard for eVTOL simulation pilot training, worldwide.

I look forward to discussing the topic of eVTOL Flight Simulation here on the VFS Open Forum and networking with others to help create a foundational standard which fosters professional, simulation based eVTOL Pilot Training.
