Gabriella Erich, a��biomedical engineering (BME) student graduating this fall, has been selected to receive the��CU ��«����Ƶ College of Engineering and Applied Science 2024 Outstanding Research Award.

This award is given to undergraduate students who demonstrate research excellence that is both interdisciplinary and impactful. Erich is the fourth BME student to win the award since the young program’s conception in 2018. But her journey to this award was a little different.

The unique, early journey

Growing up in both ��«����Ƶ and Los Angeles, Erich had two passions: space and medicine.

“When I was a kid, I had a NASA astronaut suit in my room,” Erich said. “But I also loved my chemistry classes, my biology classes and I always wanted to be a doctor.”

As college inched closer, Erich was unsure what degree path to pursue.��The decision was difficult but she eventually chose��the��Ann and H.J. Smead Department of Aerospace Engineering Sciences at the����«����Ƶ.

Erich enjoyed aerospace engineering. But she quickly discovered that she wasn’t feeling passion and she needed a change. She had also been dealing with some bad news from back home: Two of her uncles had been diagnosed with��amyotrophic lateral sclerosis (ALS), a fatal neurological disease that attacks nerve cells in the brain and spinal cord.

“Their diagnosis really sparked my passion again. I knew I wanted to switch over to biomedical engineering and assist in the research to help treat the disease and save lives in the future,” Erich said. “It was a tough transition, but it was incredibly worth it.”

Erich began taking BME courses during her fourth semester at CU ��«����Ƶ. One of them was an introductory course with��Professor Mark Borden, where she first carved out her niche in the world of biomedical research.

“I remember when Dr. Borden talked about the microbubbles that he and his students worked with in his lab,” she said. “I really had no clue what they were, but I realized his research was something I was interested in. When I saw his graduate students present it again in a different class, I decided it was something I was going to pursue.”

In the next year, Erich applied to the��Summer Program for Undergraduate Research (SPUR) and was accepted into the��Borden Research Lab.

“It was daunting at first,” Erich said. “I really wanted to make sure I impressed them. Once I got into the lab, I showed that I can ask questions and learn quickly. It became a pretty seamless transition after that.”

The award-winning research

Erich conducted multiple independent studies during her time in the Borden lab. Each of them analyzed endoskeletal droplets, exoskeletal droplets and their response to a phase transition phenomenon called acoustic droplet vaporization (ADV).

ADV occurs when liquid droplets are vaporized under ultrasound. This technique is often used to explore more precise imaging and drug delivery solutions. But endoskeletal droplets are more complex; they contain an internal solid hydrocarbon structure that allows researchers to control their stability and vaporizability.

Using ultrasound, Erich developed a testing setup using a research ultrasound transducer to study the endoskeletal droplets and their behavior under ADV. This novel research yielded results that mark the first formal characterization of endoskeletal droplets with this phenomenon.

With more analysis and improvement to the test setup, Erich believes this work can possibly help engineers and scientists discover a safer, more cost-effective method of drug delivery and treating brain-related diseases.

“There are cures for cancer like radiation and chemotherapy,” she said. “But there are problems with those. Ultrasound is noninvasive, so using these droplets could be a safer and cheaper way to deliver this type of care.”

In October, Erich was invited to present her findings at the Biomedical Engineering Society annual meeting. She is currently working on another independent study, this time analyzing the effects of ADV on exoskeletal droplets that have external solid structures. For this research, Erich is developing an electronic setup to alter more parameters using both a transmit and a receive transducer.

“It’s a similar principle as my past studies,” Erich said. “We want to see when this droplet vaporizes under ultrasound. But we want to alter a few more parameters such as pulse length, pulse repetition frequency, and mechanical index to see the effect of those on the droplets as well.”

The lasting impact

Erich has proved her worth as a researcher and community member in other areas, too. This past summer, she worked at the National Institute of Standards and Technology (NIST) developing magnetic nanoparticles for use as contrast agents in a low-field magnetic resonance imaging system (MRI). She has also served as an Engineering Ambassador, sharing her path and passion for research with prospective students and families.

Most of all, Erich hopes her college journey will inspire future undergraduates to find their passion in research. Especially those who come from a unique path, just as she did.

“I come from a non-STEM family, and I started in aerospace. I never thought I would ever have this opportunity,” she said. “I’m grateful to have been a part of this program, and I am honored to be given this award.”

The achievement of the Outstanding Research Award will be recognized at the��College of Engineering and Applied Science Graduation Ceremony on Dec. 19, 2024. Erich hopes to return to CU ��«����Ƶ as a graduate student in fall 2025 or use her research knowledge to work in medical imaging.
