April 2, 2025 – Drone demos, virtual reality goggles and miniature robots were just a few of the 200 projects on display at the Samueli School of Engineering’s Annual Design Review on Friday, March 14. Around 1,000 engineering students from the school’s six departments filled up the UC Irvine Student Center where they presented their group projects.

The senior design program gives fourth-year engineering students an opportunity to address real-world problems with innovative ideas for creative solutions. After working in teams on their projects for two quarters, students are then able to present their ideas by displaying or demonstrating them to a wider audience at Design Review. The annual event allows students to practice their presentation and networking skills, as they share their projects with alumni, industry professionals, faculty, fellow students and staff.

Engineering Dean Magnus Egerstedt welcomed everyone and encouraged students to enjoy the event. “You’ve been in classrooms, internships, all sorts of things, but this is where the rubber hits the road,” said Egerstedt. “This is where the magic is, where you show off what you’ve learned. This event right here is what the value of an Anteater engineering education is all about.”

Project teams spanned over three rooms in the Student Center. Clever and ingenious solutions were offered for important and practical issues, like a smart pet feeder, elderly care alert bracelet and sign language robot. Students kept attendees engaged with their presentations and demonstrations of interactive devices like a playable computer keyboard connected to a harp or an instant smart water bottle that can test a pH level in seconds.

Around 40 guests attended the event, including Samueli Academy High School engineering instructor AJ Polizzi, who has attended regularly over the years, as it influences how he prepares his students.

“It gives me a chance to interact with current engineering students,” Polizzi said. “And we’re feeding back what you guys are doing here to help motivate our students to pursue that work in high school. We go back to the kids and say, ‘hey, look, this is what they’re doing over in college.’ We are teaching them the same lesson: going from an idea to a design to a product.”

The three-hour event ended with the announcement of the Dean’s Choice Awards. Of the 21 nominations, 12 projects were recognized. The dean and a team of graduate student judges selected the winners based on the following criteria: if the project solves an important problem, if it is practical and if it has the wow factor. Below are this year’s Dean’s Choice Award winners.

UC Irvine Magazine | Winter 2025

Three to five out of every 1,000 babies are born with a port-wine birthmark, a splash of red or purple on the skin somewhere on the body, mostly commonly the face. Unlike smaller, lighter birthmarks, port-wine marks can darken, thicken and develop complications such as bleeding and infections – and may be associated with other conditions like glaucoma and even seizures.

“They can also impact a person’s social interactions and psychological well-being, particularly when they cover a sizable portion of the face,” says Dr. Kristen Kelly, UC Irvine professor and chair of dermatology.

Using a pulsed dye laser, she zaps the purple-tinted blood vessels, heating them with intermittent bursts of light until the blood flow stops and the vessels break or develop clots and resolve. The targeted therapy sometimes requires as many as 30 treatments to effectively lighten a port-wine birthmark.

UC Irvine scientists have been at the forefront of addressing these signature marks for more than a decade. Dr. J. Stuart Nelson, medical director of the Beckman Laser Institute & Medical Clinic, pioneered the first cooling laser device in 1994, revolutionizing treatment for individuals with port-wine birthmarks. The cooling device protects the surface of the skin, allowing doctors to safely deliver higher doses to event the youngest patients while minimizing the possibility of complications. Depending on the size and depth of the blood vessels, many people experience dramatic benefits.

Unfortunately, the discoloration sometimes reappears. “The risk of vessels returning is lower when we start treatment during the first year of life,” says Kelly, whose patients range from infants to individuals in their 90s. To reduce recurrence, UC Irvine researchers are investigating approaches to combine lasers with medication. New medicines may need to be developed, Kelly adds.

These epidermal anomalies aren’t just a cosmetic concern. They can thicken the skin, produce nodules and, in some cases, affect the organs, including the yes or brain. “Since we don’t know which patients are going to develop progression or complications,” Kelly says, “it’s important for anyone who has a port-wine birthmark to seek car from a qualified expert.”

Conference: American Academy of Dermatology

Expect exciting news in the treatment of port-wine birthmarks, Kristen Marie Kelly, MD, told AAD Annual Meeting attendees.

Kristen Marie Kelly, MD, FAAD, highlighted promising advancements in the treatment of vascular malformations, particularly port-wine birthmarks at the American Academy of Dermatology (AAD) Annual Meeting.¹ Although lasers have significantly improved patient outcomes, she said, some lesions remain resistant, and recurrence continues to be a challenge. However, Kelly said new research offers hope for more effective therapies.

According to Kelly, chair and professor of dermatology at the School of Medicine, University of California, Irvine, energy-based devices remain a cornerstone of treatment, but there are emerging strategies that involve combining them with targeted medications. In her talk, “What’s Next: Future Directions for the Treatment of Port Wine Birthmarks,” she explained a deeper understanding of the genetic mutations underlying vascular malformations is paving the way for innovative approaches. “Our treatments have improved, but for resistant lesions, there is hope for the future,” she said.

Recent studies have explored the potential of adjuvant therapies, including rapamycin and imiquimod, but these have produced only modest benefits, Kelly told Dermatology Times. However, ongoing aim to identify medications that more precisely target the affected pathways. Kelly said, “New drugs are being screened, and my hope is that when we find one that really targets that pathway, the combination will be very powerful.”

Kelly emphasized the importance of continued research and professional education. For those who want to be sure to stay up to date, she suggested attending conferences such as AAD Annual Meeting. The American Society for Lasers in Medicine and Surgery (ASLMS) is also a useful resource, she said, as they provide key platforms for dermatologists to stay updated on the latest advancements. “There’s a lot of research going on in terms of new potential treatments, and people should continue to watch for more exciting options,” she told Dermatology Times.

With the integration of genetic insights, novel therapeutics, and advanced laser technologies, the future of port-wine birthmark treatment is evolving and is promising, Kelly indicated. For dermatologists, she added, staying informed about these developments will be crucial in optimizing patient care and improving long-term outcomes.

Tom Milner, former UC Irvine professor of surgery and biomedical engineering, makes revolutionizing laser medicine sound easy.

“It was a pretty smooth path. The first time we tried it, we thought, ‘Hey, this looks like it’s going to work,’” he says about his work on lasers thirty years ago.

Milner, who recently served as the director of the Beckman Laser Institute, was a vital part of the team that invented the Dynamical Cooling Device (DCD), a medical device that sprays a cooling agent onto the skin before a laser pulse to enhance effectiveness and lessen pain.

The DCD developed from an epiphany, Milner’s colleague, distinguished professor of surgery and biomedical engineering J. Stuart Nelson, had while watching a player get hit by a “stinger” during a baseball game. He noticed how after the hit, a trainer would spray a cooling agent on the player’s injury to numb the pain.

Milner’s research team was in the midst of applying for grants from the National Institutes of Health (NIH) when Nelson wondered whether a cooling agent could be used in combination with lasers to cool and numb the skin. Over dinner, Nelson discussed his idea with Milner and visiting engineer Lars Svaasand, and the three agreed the idea had legs.

After spit-balling their ideas over the weekend, Milner went out to buy a valve while Svaasand and a student went down to the local Pep Boys to purchase R-134a, a refrigerant commonly used in automotive air conditioning systems. In the lab, they connected the refrigerant to the valve and controlled the valve with a delay generator that created a pulse to trigger the spray. In a short amount of time, their first prototype was built. The result: a breakthrough device that has since treated millions of patients and shaped the future of laser medicine.

Cold Comfort

Before the invention of epidermal cooling, the effectiveness of laser treatment was limited by the laser’s intensity. The heat caused patients pain, possible scarring, and pigmentation changes in the skin. Plus, the treatment wasn’t effective on patients with darker skin tones, since melanin in the epidermis, or top layer of skin, limited the amount of light that could reach the blood vessels that physicians were trying to treat.

When Milner first arrived at UCI in 1992, he was a research fellow joining Nelson’s team. Nelson, who is also the current medical director at the Beckman Laser Institute, was trying to come up with a more effective way to treat port-wine stains, hemangiomas, and other vascular malformations.

“We understood from the physics point of view that it was a question of how to make the skin really cold in a short amount of time,” Milner says.

The team’s challenge was to find a way to protect the outer skin while allowing the laser to penetrate deeper to the blood vessels that created these vascular abnormalities. They knew they needed to cool the skin; it was just a matter of how.

Before coming up with the cooling spray idea, the team’s original plan was to bring a cooled window onto the skin before quickly removing it.

“To me, this seemed a lot harder to build than spraying a liquid on the skin with a valve. Since I was the person who had to execute the solution, I preferred the new idea,” Milner says.

A Big Step Forward

The DCD works by delivering a quick burst of a cryogen or cooling agent, onto the skin immediately before, and often after, a laser pulse. The cryogen evaporates and the laser is triggered to target blood vessels in the dermis (the thick part of the skin under the epidermis). The technology is then incorporated into a handheld laser device that is used by a physician.

Once cooling was implemented to protect the skin’s surface, higher energy levels could be used to produce greater effectiveness. The technology also expanded treatment to patients of all skin types by mitigating the blocking effects of melanin. It also reduced patient discomfort by minimizing injury to the skin.

Dermatology chair Kristen Kelly was a research fellow at the time and worked with Nelson on studies investigating the DCD’s early uses.

“The DCD greatly advanced laser skin surgery. We’re able to provide treatment to a wider range of patients. It made the treatments less uncomfortable, and it helped to increase our efficacy. It really was a big step forward,” she says.

Cool Collaborators

Creating the device turned out to be the easy part. While the physical construction of the DCD presented minimal challenges, its complexity lay in comprehending its interaction with human skin. This is where Milner and his colleagues spent most of their time. They needed to measure the temperature of the skin as it cooled and the temperature of the skin when the laser was fired. They had to ensure their measurements were mathematically predictable and confirm their theoretical understanding of its behavior.
