USC Viterbi materials science Ph.D student Ashley Maldonado Otero was recognized with the highly competitive NASA Space Technology Graduate Research Fellowship. This prestigious award recognizes Maldonado Otero’s exceptional potential in the field of nanomechanics and materials science, supporting her research into the development of strong, lightweight materials for aerospace applications. Maldonado Otero works within the Materials Research Group led by Andrea Hodge, Fluor Professor in Engineering and chair of the Mork Family Department of Chemical Engineering and Materials Science.
The NASA fellowship provides up to four years of financial support, including an annual stipend of $40,000 and additional allowances for research expenses, health insurance, and tuition. Recipients of this award are expected to contribute to groundbreaking, high-risk/high-payoff early-stage space technology research.
USC Viterbi spoke with Maldonado Otero to learn more about her research and aspirations.
How does it feel to be the recipient of a NASA Space Technology Graduate Research Fellowship?
When my advisor, Dr. Hodge, first called to share the news, I couldn’t believe it. It’s an incredible honor to receive this fellowship and I feel deeply humbled and excited about the opportunity. This milestone has made me reflect on how fortunate I am to have had such inspiring mentors who have supported me throughout my journey. I’m also genuinely proud of myself for this achievement— it reinforces my passion for research and my drive to contribute to the development of advanced technologies.
Can you provide an overview of the research you’ll be working on as part of this fellowship?
My research aims to understand the microstructure and mechanical behavior of engineered materials at very small scales. The idea is to make and engineer nanomaterials that are both strong and lightweight, which are desired for aerospace, at an accelerated pace to keep up with the demands of rapidly growing advanced technologies.
What are some of the novel applications that could result from advancements in this field?
Advancements in this field could lead to several novel applications. Breakthroughs in nanomaterials could enhance advanced materials used in aerospace, automotive, construction and energy sectors, leading to more durable and robust components. For instance, in the energy sector, these advancements could result in the development of more efficient batteries, solar cells, or stable materials for nuclear applications. In aerospace, some novel applications include structural components for spacecraft, rovers for the moon and Mars, etc., able to withstand the extreme conditions of space.
What are some of the potential real-world impacts or applications of your research?
Some potential real-world applications of my research include being able to develop materials that can withstand the harsh conditions of the lunar environment, including abrasion, radiation, and large temperature fluctuations. Additionally, it focuses on accelerating the discovery and development of these advanced materials, paving the way for more efficient solutions across a wide range of applications.
What first sparked your interest in studying engineering and this particular area?
Ever since my early childhood in Puerto Rico, I found myself captivated by the Milky Way galaxy visible from my home. I always wanted to work at NASA, following in the footsteps of scientists and pioneers such as astronaut Joseph M. Acaba, a fellow Puerto Rican.
Also, as a Caribbean island native who has experienced firsthand a lack of access to basic infrastructure, I always wondered how to improve the quality of life for my people. Back in 2017, Puerto Rico was directly hit with one of the most powerful hurricanes to date: Hurricane MarÃa. The already unstable electric grid on the island was destroyed, leaving the entirety of the country in the dark. Millions of people suffered due to power outages, but the resilience of my people against adversity, both in the past decade and across centuries, has always been a huge inspiration for me, and a reason why I pursued a career in engineering and materials science to help solve the world’s issues, including applications in aerospace and the energy sector.
What excites or inspires you most about your field of research?
I am passionate about my research field in nanomaterials because it allows me to be at the forefront of emerging technologies, offering solutions to the pressing societal challenges that matter most to me. My field of research can also be applied to a wide variety of applications, making it fun and exciting to tackle different challenges.
Conducting research can often involve overcoming challenges. Can you discuss one of the biggest challenges you’ve faced so far and how you overcame it?
One of the biggest challenges I’ve faced during my research has been learning how to handle setbacks. At first, it was hard to accept when things didn’t go as planned, but I’ve realized that it’s a natural part of the research process—and of life. When I started my Ph.D., I felt this constant pressure from myself to accomplish things quickly. But through the support of USC’s mental health services, I’ve learned to give myself grace and recognize that developing the skills to become a good researcher takes time. That’s why Ph.D.s span several years—they allow space for learning, growth, and resilience.
Another challenge has been being away from my family. It’s not always easy, but I’ve found comfort and connection by building my own community here. Activities like playing beach volleyball, joining intramural sports at USC, and salsa dancing have helped me stay grounded and maintain balance. These experiences have made this journey not just about research but also about personal growth and finding joy along the way.
Where do you see your career heading after completing this fellowship and research?
After completing this fellowship and research, I initially see my career heading toward the energy sector, a path deeply shaped by my experiences back home. I aim to return and contribute to the development of stronger, more resilient, and cleaner renewable energy sources. I plan to work on materials for these applications that ultimately affect life in Puerto Rico and other countries with brittle infrastructure against the adverse effects of climate change.
Beyond the technical work, I’m passionate about continuing to grow as a proud Latina mentor. I want to be someone who not only supports future generations of diverse people in science with technical guidance but also provides the personal encouragement they need to thrive. Representation matters, and I hope my journey can inspire others to dream big and push boundaries in STEM.
Any words of advice for other students looking to pursue research opportunities like this?
My biggest word of advice is not to be afraid to take the risk and go for it! Don’t let self-doubt hold you back—we’re often our own toughest critics, setting limits on what we think we’re capable of. If it works out, that’s incredible. If it doesn’t, that’s okay too because every step, even the setbacks, teaches you something valuable along the way.
I’d also say to surround yourself with mentors who truly inspire you and push you to chase your passions. Having role models who’ve walked the path you’re on can make a huge difference. They can share their experiences, give you advice, and guide you through the ups and downs. Building those connections has been one of the most important parts of my own journey.
