Payton Martinez, a recent��biomedical engineering (BME) PhD graduate, has been selected to receive the�����Ҵ�ý�ƽ������ College of Engineering and Applied Science 2024 Outstanding Dissertation Award.

This award is given annually to a doctoral research student completing their PhD degree requirements whose written dissertation demonstrates outstanding quality, research excellence and topical importance.

Growing up in the Denver area, Martinez would often take apart electronic devices to study their mechanisms and understand how they worked. He said he loved math, science and working with his hands.

As Martinez became older, he took a sharp interest in medical technology and neuroscience. He began to notice family members going in and out of the hospital for various illnesses, and he wondered about the risks associated with the treatments they were being given.

“I realized that I wanted to use engineering to focus on something valuable,” Martinez said. “Not an item or a product like a television. Something valuable like the lives of humans or even animals.”

Martinez attended the University of North Carolina at Chapel Hill and received his undergraduate degree in biomedical engineering. He was then introduced to the��Borden Research Lab, led by��Professor Mark A. Borden at the��University of Colorado Boulder.

Here, he was able to continue his studies in�����Ҵ�ý�ƽ������ BME graduate program and quench the thirst for all his curiosities at once: medicine, technology and neuroscience.

Martinez’ dissertation is titled�� The research explores how ultrasound and microbubbles can potentially work in tandem to effectively deliver drugs to the brain and treat neurological diseases in the future.

According to Martinez, neurological disorders were the second leading cause of death in 2016. This is not because our drugs and therapeutic treatments are ineffective. Instead, Martinez argues we need to improve drug delivery methods in order to reach these brain-related illnesses.

“Many pharmaceutical companies have developed drugs over the years that work super well when you have the drug and cell right next to each other,” Martinez said. “But our brains have a blood-brain barrier that prevents these effective drugs from getting past and attacking the cell.

“The big issue when it comes to neurological diseases and brain cancer is taking the drugs and figuring out a way to deliver them to humans.”

During his time in the Borden lab, Martinez focused specifically on diffuse intrinsic pontine glioma (DIPG), a brain tumor located in the pons region of the brain that primarily affects children.

This rare form of cancer is unique. While some cancerous tumors have a slightly leaky or porous blood-brain barrier, allowing certain drug treatments to pass, the DIPG blood-brain barrier is fully intact. This makes the cancer almost impossible to treat in any way that is both safe and cost-effective.

“Using the technology we developed in the Borden lab, we were able to pass through the blood-brain barrier and reduce the tumor size in mice,” Martinez said. “Of course, this is on a much smaller scale than treating humans. But overall, we were able to increase the survival of these tumor-bearing mice.”

Martinez looks to expand on this research even further in the future. He is currently a postdoctoral researcher at Stanford University using ultrasound and microbubbles to possibly treat other neurological ailments as well. His goal is to remain in academia and eventually start his own lab where he can continue to push the limits of his research and discoveries.

The achievement of this award will be recognized at the��College of Engineering and Applied Science Graduation Ceremony on December 19, 2024.

More than anything, Martinez wants to give thanks.

“I’m extremely grateful to receive this award, and I am thankful for my advisor, Mark Borden, for nominating me,” Martinez said. “Thank you to everyone who helped me along the way. A lot of my journey was learning from experts and mentors and it’s extremely impacted what I know and have done today.”
