Innovating Cancer Therapy: Carolyn Schutt Ibsen’s Breakthroughs in Ultrasound-Driven Drug Delivery.

Dr. Carolyn Schutt Ibsen, a biomedical engineer at Oregon Health and Science University (OHSU), is transforming the landscape of cancer treatment through the use of ultrasound-based drug delivery systems. Her innovative research combines engineering principles with biological insight to create novel solutions for tumor targeting and tissue engineering.

Schutt Ibsen’s fascination with building and deconstructing complex systems began in childhood. This innate curiosity, paired with her personal experiences watching family members undergo cancer treatments, fueled her decision to pursue biomedical engineering. Seeking a meaningful and impactful career, she joined Dr. Sadik Esener’s lab at the University of California, San Diego, where she explored advanced drug delivery systems using ultrasound.

During her doctoral research, Schutt Ibsen focused on nanomedicine, particularly ultrasound-responsive microbubbles—tiny, gas-filled structures capable of carrying therapeutic payloads. These microbubbles remain inert until activated by specific ultrasound frequencies, at which point they rupture, releasing their contents. The resulting shockwaves and microjets enhance cell membrane permeability, facilitating the targeted delivery of drugs or genetic material.

Collaborating closely with both engineers and biologists, she refined methods for encapsulating DNA and microbubbles within liposomes and studied how variations in lipid composition and spatial arrangements influenced their responsiveness to ultrasound. Her work aimed to optimize these microbubble systems for clinical applications.

Toward the end of her PhD, Schutt Ibsen became intrigued by the potential of applying this technology to tissue engineering. This led her to join the lab of Dr. Molly Stevens at Imperial College London, where she helped introduce ultrasound systems to create energy-responsive materials within 3D tissue constructs. Drawing from Stevens’s expertise in biomaterials and interdisciplinary collaboration, Schutt Ibsen developed ultrasound-sensitive hydrogels that could be manipulated remotely, opening new possibilities for regenerative medicine and therapeutic delivery.

Inspired by Stevens’s leadership and the lab’s broad scientific scope, Schutt Ibsen adopted a similarly integrative approach when she established her own lab at OHSU in 2018. Her research centers on merging energy-responsive materials with tissue engineering and cancer biology. One of her notable achievements includes creating a bioink that responds to ultrasound, enabling researchers to precisely control gene delivery within 3D-printed tissue models. This innovation holds promise for both cancer gene therapy and regenerative medicine.

Schutt Ibsen’s pioneering contributions earned her the 2024 Young Innovator in Cellular and Molecular Bioengineering award from the Biomedical Engineering Society, following the Rising Star Junior Faculty Award in 2023. Colleagues, such as materials engineer Dr. Lesley Chow, have praised her originality and passion for collaboration, noting a strong professional bond that began at a scientific conference and continues to this day.

Beyond her advances in drug delivery, Schutt Ibsen is also addressing a major gap in cancer research: understanding the early stages of tumor development. By working closely with clinicians, her team is building models of precancerous tissues using energy-responsive biomaterials. These models allow precise stimulation of oncogenesis in individual cells, enabling the study of how 3D microenvironments influence tumor formation. Chow, who has focused on biomaterials for regenerative medicine, highlighted how Schutt Ibsen’s work introduced her to ultrasound as a novel method of cellular control—one that is gaining momentum in the bioengineering field.

Looking ahead, Schutt Ibsen is exploring the integration of biosensors into her 3D structures to monitor cellular environments. She also envisions developing a library of energy-responsive materials that could be used to orchestrate complex gene expression patterns across different tissue regions.

While her groundbreaking research continues to earn accolades, Schutt Ibsen considers mentorship her most rewarding achievement. From her graduate school days to her current role as a principal investigator, she has made it a priority to support young scientists. “One of the best moments is when a student tells me, ‘I got it to work,’” she said. “Watching their growth is the most fulfilling part of this journey.”

Her collaborative spirit, innovative mindset, and dedication to mentorship are making a lasting impact—not just in the lab, but on the future of cancer therapy itself.
