Tim Cheek’s engineering interest grew from his high school physics and chemistry courses. His original concentration of electrical engineering soon evolved into materials engineering degrees. Tim started his career as a consultant where he learned the relationship between failure analysis and forensic engineering.

Prior to arriving at DELTA |v|, Tim Cheek spent seven years at a commercial vehicle manufacturer. There he was responsible for the metallurgical lab where he handled failure analysis and truck product & design development. Although Tim enjoyed that experience, he missed the client interaction that consulting allowed. In 2005, Tim moved to Charlotte to join the DELTA |v| team. Tim is DELTA |v|’s resident vehicle product liability expert with a specialty in material failures, heavy truck systems, and truck fire cause & origin. He also handles commercial vehicle accident reconstruction matters nationwide with a special interest in Event Data Recorder extraction.  He is the primary point of contact for imaging Mack/Volvo’s HVEDRs, as authorized by the manufacturer. In 2017, Tim became the Regional Manager for the firm’s Charlotte office.

Because much of his workweek involves traveling, Tim spends his time off close to home. His ideal day off would be spent in a local hammock with a cool breeze and a good book.

Don Roberts knew early on that he wanted to follow in his father’s footsteps and become an engineer. And it was Don’s extensive military background that eventually helped him achieve it.  After receiving a Bachelor’s degree in Mechanical Engineering from the U.S. Naval Academy, Don joined the submarine force as a commissioned officer on three nuclear-powered vessels. He returned to the Naval Postgraduate School to complete his Master’s degree in Mechanical Engineering and gained vital experience as an instructor at the academy.

Don entered the motor vehicle accident reconstruction industry in 2001 and, in 2008, moved from Charleston, SC to join the Charlotte office of DELTA |v| as a Professional Engineer.  Now, as a Senior Engineer, Don is regularly involved in complex commercial vehicle accidents involving full scale reenactments and human factors issues.  He is also well versed in harvesting onboard digital data from vehicles of all kinds.  Don’s teaching experience gleaned from his time at the military academy and his calm demeanor have made him an effective communicator in high-pressure legal proceedings.


Tyler Black hit the ground running with the DELTA |v| Charlotte office in 2014.

He has a can do, adventurous attitude as demonstrated by his willingness to relocate his family from Charleston to join the firm.  He has unique experience in vehicle rollover reconstructions and uses advanced 3D modeling techniques to determine vehicle speeds and occupant ejection portals.  Tyler is always ready to hit the road for rapid response assignments where timely capture of critical scene evidence helps clients resolve motor vehicle claims.  Tyler has an innate ability to clearly discuss highly technical matters when testifying in legal proceedings.

Tyler cut his teeth in the accident reconstruction industry for seven years prior to joining the company.  He graduated Magna Cum Laude with a Bachelor’s degree from Clemson University and obtained a Master’s degree in Mechanical Engineering from Purdue University while working full-time and starting a family.  His emphasis in graduate school was on vehicle systems and dynamics, which has enhanced his credibility in testifying on reconstruction matters.

Tyler and his family admittedly miss the seaside life of Charleston but are grateful to be part of a dynamic company that invests in his professional development. Instead of walks on the beach, Tyler and his family enjoy the local attractions of Charlotte including Discovery Place, the U.S. National Whitewater Center, and Carowinds.

Garrett Wood, Professional Engineer, began his career at DELTA |v| in 2015 after earning his Ph.D. in Biomedical Engineering, with a focus in Injury Biomechanics, from Duke University. Garrett also holds a Bachelor’s degree in Mechanical and Biomedical Engineering from Duke University.

As an undergraduate and graduate student, Garrett worked in the Duke Injury Biomechanics Laboratory as a research associate. He investigated blast and blunt trauma models for traumatic brain injuries and Hybrid III dummy skin for automobile crash applications.

Garrett’s education and friendly personality make him a great addition to the DELTA |v| team. He is regularly involved in field work, which includes data collection, truck downloads and investigations. He is also entrenched in drawing production, vehicle accident reconstruction and vehicle system analyses. Garrett brings his unique background in crash injury biomechanics to the DELTA |v| list of services and thoroughly enjoys analyzing these types of incidents.

Originally from Charlotte, Garrett is happy to be back in the area. On weekends he enjoys spending quality time with his family and participating in outdoor activities such as camping, fishing and hunting. You may also catch him cheering on the Duke University basketball team from time to time.

Jay Shridharani, Senior Associate Engineer, joined DELTA |v| in 2017 after earning his Ph.D. in Biomedical Engineering from Duke University. Jay also holds a Master’s degree in Biomedical Engineering from Duke University and a Bachelor’s degree in Mechanical Engineering from Virginia Tech.

Jay’s doctoral research focused on investigating the injury mechanisms in the spine from naval high speed craft and underbody blast exposure. He has also extensively researched traumatic brain injury (TBI) from primary blast and ballistic impacts. His education and research experience allow him to offer a unique perspective to DELTA |v| clients in their accident reconstruction matters.

A typical day of work for Jay may involve field work, including data collection, truck downloads, and investigations. He is also entrenched in vehicle accident reconstruction.

With family in Charlotte, Jay has settled into his new city well. Jay enjoys spending quality time with his family and friends. You may also find him enjoying the outdoors, cooking Mexican food, or installing smart home features throughout his house.
