Traversing any crowded, busy roadway brings myriad safety risks and demands on a driver’s attention. And even the most careful of drivers can’t control those driving around them, particularly the ones creeping up from behind.

“Don’t you dread the sound of screeching brakes from the car behind you, as you brace for the impact?” asked Emma Devine, a ��AV systems engineering and operations research student who was part of a team—appropriately named “UR 2 Close”—that won two contests and finished second in another for their work on investigating rear-end collisions.

Devine and teammates Amanda Dalagan and Aidan Menon took first place in the public engagement track at the Costello College of Business Patriot Pitch Competition and in the general engineering track at the General Donald R. Keith Memorial Capstone Conference at West Point. Solutions are sorely needed, as rear-end collisions account for nearly one-third of all automobile accidents each year, resulting in thousands of deaths.

“We conducted a detailed analysis of crash data and found that most rear-end collisions occur on straight segments on highways, in good weather conditions, and in the late afternoons and evenings. This was a surprise,” said Dalagan.

The team’s solution is a license plate visual indicator. “There is presently no product designed to help drivers maintain safe following distances," Menon said. "There are heads-up displays and automated braking systems; those work to make sure you don't rear-end someone but do not protect you from being rear-ended. We thought a defensive approach would separate us from the pack.”

The team developed a simulation of vehicle dynamics during braking and accounted for driver reaction time, braking efficiency, and road conditions, concluding that following distance was a key criterion resulting in a rear-end accident. Observing a local road revealed only 20% of vehicles maintained a safe following distance.

“The Virginia Commonwealth Driver Regulations requires drivers to maintain a two-to-three second separation. But humans can't see time,” said Devine. “The solution to preventing rear-end collisions is to provide the following driver a clear indication of a safe following distance.”

Earlier this year the National Highway Traffic Safety Administration finalized a new standard mandating automatic emergency braking technology for all passenger cars and light trucks by September 2029, which will no doubt further help with such collisions.

“It was a privilege to sponsor this student team,” said Skip West, founder and CEO of Maxsa Innovations, a company that markets automotive products. “This project really emphasized the importance of systems engineering in doing analysis to understand the real problem before spending time and money developing a solution that may not work. These accidents are an important societal problem that we need to address, and this team has made a great start.”

Part of the charm of tiny Tangier Island, located smack dab in the middle of the Chesapeake Bay, is that in some ways it seems stuck in time, with residents speaking an outdated dialect and relying on crabbing for a living. What isn’t so endearing to residents about their simple life is the need to take a ferry to the Eastern Shore to obtain necessities, such prescription medications. Such a trip is an all-day affair, often causing people to miss work and lose wages.

But now Riverside Health System and DroneUp, a delivery service based in Virginia Beach, are working with a team of ��AV students to deliver medications via a small drone. But even that poses challenges.

“As a part of my systems engineering senior design project, my team and I performed a context analysis and a stakeholder analysis to find the performance gaps for a case study about drone delivery to an island located in the Chesapeake Bay–Tangier Island,” said senior Diana Machuca, who is majoring in systems and industrial engineering. “To bridge the gaps, we designed the Drone Range Dynamic System and came up with a business plan for the project.”

“The route is 15 nautical miles (NM) from Onley, Virginia, to Tangier Island,” said team member Darius Jack. “The route traverses both land and terrain resulting in significant wind shifts, including onshore and offshore winds, depending on the time of day.”

Depending on a drone’s design, it can be very sensitive to wind, requiring extensive analysis. Team member Grean Ramos said, “We developed an aerodynamic simulation of the drone and its batteries. The simulation showed that the 15 NM route is close to the drone's range limit. Any unexpected headwind could result in the drone running out of battery and needing to land before reaching Tangier Island.”

“There are weather stations at Onley and at Tangier Island airports, but no weather stations in-between," said team member Diana Machuca. "We analyzed one year of hourly wind data from the airports and found that headwinds would prevent the drone from reaching the clinic 32 percent of the time.”

So the team developed a Drone Range Decision-support System (DRDS). The DRDS uses the aerodynamic simulation described above to continuously monitor the range-remaining as the drone flies. If the simulation estimates that the drone has experienced an unexpected wind and will no longer have enough battery power to reach the destination, it recommends the drone operator to return home (if it can) or to land safely in designated landing zones. Simulations showed winds would require the drone to return home 17 percent of the time.

The team’s plan won First Place in the STEM Track in the Patriot Pitch Competition, a annual contest sponsored by the Costello College of Business at George Mason, and First Place in the Systems and Analytics Track at the Sage Memorial Design Competition, a student-focused international forum for the design of complex systems.

“Working on this project was an amazing experience,” said Jack. “We had to use all the system engineering knowledge and skills we learned over the past three years. Building systems in the real-world is hard, but perseverance and creativity pay off.”

When Shrishti Singh came to ��AV for her doctoral studies, she had a goal in mind: developing a new technology that would allow the visualization of cancer in deep tissue and perhaps enable earlier diagnoses.

Using a combination of FDA-approved dyes for photoacoustic imaging, Singh created an injectable contrast agent that attaches to tumor cells and increases the visibility of those cells against the background tissue.

Singh completed her PhD in bioengineering in 2022, but her relationship with the university continues. During her time at Mason, Singh has used all the tools the university provides to bring her discovery to the marketplace.

In April 2023, Singh was on one of the 15 teams that competed for $40,000 in prizes at the Costello College of Business annual Patriot Pitch Competition. She took home first place and the Mason’s Choice Award in the competition’s science, technology, engineering, and math (STEM) track.

In November 2023, Singh was at Mason Square pitching her technology at Mason’s annual Accelerate Investor Conference, which attracts more than 400 entrepreneurs, investors, students, and members of the Washington, D.C., entrepreneurial ecosystem. She was awarded $2,000 for her efforts.

“I'm a researcher by training. I've been trained to present at scientific conferences so talking in front of an audience was not difficult for me,” said Singh. “The difficult part was assimilating all of the business information that I've learned so far into a presentation or a slide deck, and to be able to present that in a time-constrained environment.”

Singh, now a postdoctoral fellow at Mason, has cofounded a company, NIRView Biosciences, with her bioengineering faculty mentors Remi Veneziano and Parag Chitnis, and Singh and NIRView Biosciences have been designated a 2023 Virginia Small Business Development Center (SBDC) Success Story.

“As we develop the company, [Veneziano and Chitnis] are involved in creating strategy and vision of the company, along with helping me write grants and obtain funding,” she said. “They provide me with mentorship on the technology front to be able to take this company forward.”

Singh and her cofounders were a few of 30,000 entrepreneurs who participated in a Virginia SBDC workshop, seminar, or training in 2023. Through its 16 programs, the Virginia SBDC, which is part of Mason Enterprise, helped 10,000 businesses, provided 40,000 hours of one-on-one counseling, offered 1,600 training programs, and incubated more than 550 companies with an impact of $3.36 billion. Of the businesses served, 61% were woman-owned, 46% were minority-owned, and 15% were veteran-owned.

“The SBDC has been one of our biggest supporters,” Singh said. “I work extensively with my SBDC mentor, Elizabeth Pyle, who is always ready to be to give us advice on how to take the business forward.”

Singh and Veneziano participated in SBDC’s Innovation Commercialization Assistance Program (ICAP), a no-cost incubator that helps technology start-ups from ideation to initial funding and beyond. They worked with ICAP’s life science business mentors over the course of a year to position their technology for successful commercialization, and in 2023 they were accepted into the National Science Foundation’s I-Corps program, which provides financial support and experiential education to help university researchers commercialize scientific discoveries.

“The support of SBDC has been tremendous,” said Singh, who also has a master’s degree in biomedical engineering from the University of Bridgeport in Connecticut and an engineering degree from Ramaiah Institute of Technology in Bangalore, India. “My training has been on the scientific front, so SBDC helped me learn different aspects of the lean business model canvas, customer discovery, and product-market fit, which was a new learning curve for me.”

Singh said while she chose Mason originally for its diversity, it is the people and community here that have made a difference in her life. “I have made friends, and I have gained mentors that are still an active part of my professional life,” she said. “I have been able to take this education and put it toward a better professional vision that I've always wanted. I can say Mason is the reason I have been able to accomplish a lot of my dreams.”

Costello College's Patriot Pitch Competition supports idea and early-stage business ventures and is open to current Mason students and recent alumni from all majors/fields of study.
