Daniel (Dan) Bowman, Professional Engineer, joined DELTA |v| in 2015 looking for a place to express his investigative nature and he hasn’t looked back since. Daniel is one of DELTA |v|’s go-to guys for creating 3D simulations using HVE (human, vehicle, and environment), a software program that uses physics and data from an incident to produce incident recreations, create steering and brake input visuals, evaluate driver responses, and explain vehicle handling behaviors. Senior engineers and clients are able to use this information to better understand how an incident unfolded.

In search of warm weather and a reputable engineering degree, Daniel moved from upstate New York to attend Georgia Tech, earning his Bachelor’s degree in Mechanical Engineering in 2014. Before joining DELTA |v| he worked as a high school math and science teacher, where he sharpened his knowledge sharing and explanation skills. These skills have proven useful in his role at DELTA |v|. In January 2022, Dan took on the role of Regional Manager in the Nashville office.

Daniel is competitive by nature so he enjoys playing basketball, soccer, golf, and football. He is also inquisitive, so he enjoys exploring in his boat.










John Liechty joined DELTA |v| in 2016 and he has been a great addition to the team. His excitement about the heavy vehicle event data recorder (HVEDR) and accident reconstruction work DELTA |v| is doing, as well as his longtime friendships with a few DELTA |v| employees, have helped him fit in very well.

His areas of specialization include passenger and commercial motor vehicle collision analyses, vehicle-pedestrian accident reconstructions, collision speed analyses, acceleration and braking analyses, vehicle dynamics, brake system inspections and evaluations, and failure analyses. He is also well-versed in giving depositions and in-trial testimonies.

John received his Bachelor’s degree in Mechanical Engineering from Auburn University. He’s since participated in various continuing education opportunities, including the most recent ARC-CSI Crash Conference hosted by the Collision Safety Institute and Collision Publishing.

John knew from the age of seven that he wanted to follow in his father’s footsteps and become an engineer.  As a kid and later as a teenager he would help his father keep the family vehicles in good order and on weekends he would help friends work on their dirt track cars, hot rods, and road racers.

John applies his love for motor vehicles and problem-solving to his latest auto restoration project, a red 1974 Chevy Camaro. He also enjoys exploring the great outdoors, whether that’s by riding his motorcycle or hiking through the backcountry.


Stephen Panoff joined DELTA |v|’s Nashville Regional office in 2023 as Senior Engineer. He is a University of Michigan – Dearborn graduate with a master’s of Science in Engineering with a concentration in Energy Systems Engineering. 

In his role, he likes that every case is different, which keeps things interesting in his day to day.    

In his free time, he loves to spend time with his kids, workout, mountain bike, and spend time outdoors; preferably at the beach.  

Eric Speer joined DELTA |v| as an Associate Engineer in 2018. Before joining DELTA |v|, he was a Field Quality Engineering Intern at Nissan Motor Corporation and conducted biomechanical research at Vanderbilt.

He chose DELTA |v| because of its culture of promoting the engineering discipline and its service to clients. Eric is excited to be working with and learning from a team of talented engineers with diverse backgrounds.

He is constantly striving to increase innovation in the engineering profession while making a difference in the lives of clients through his analysis. Even before his graduation from Vanderbilt University with his BS in Engineering, Eric was finding ways to positively impact the lives of those around him. His undergraduate senior design project—developing a shock tube that replicates an IED blast—was one such innovation. Not only did the lengthy design process yield a viable final design for his sponsors, but it could help shape future development of advanced protective equipment that could save the eyesight of service men and women exposed to an explosion.

You will see a bit more of Eric’s naturally competitive nature outside of work. In his spare time, he enjoys spending time with friends and family playing board games, tennis, and golf. His favorite hobbies are water sports (slaloming and wakeboarding) and tennis. You may even catch him at a local concert or two.

Aaron Kuykendall began his career at DELTA |v| in 2021 as an Associate Engineer for our Nashville Regional Office. A bright and diligent individual, Aaron graduated in May 2021 with a B.S. in Mechanical Engineering and a Business Minor. 

Aaron’s work day consists of assisting in fieldwork and interpreting the physical evidence of motor vehicle accidents. He is excited to work for DELTA |v| for the new challenges and unique cases he will solve each day.

Aaron’s interest in science and engineering goes back to his childhood. In high school, he was an active member of the VEX robotics team. His team won the State Programming and Driving Competition in addition to placing eighth at the 2014 World Championship in Kentucky. 

Outside of work and academic pursuits, Aaron enjoys bouldering, spending time with his wife and friends, and listening to music.
