Celebrating PRISM: SARSEF’s Newest Program on Research Mentorship

On December 6th, 2025, SARSEF celebrated the achievement of the first cohort of PRISM by inviting friends, family, teachers, and community members to come hear about the incredible research the high school students have done with their mentors over the past 15 weeks. Students gave oral presentations on their research and then participated in a poster session where community members were able to ask questions about student experience and learn first hand about their research.

What is PRISM?

Partnership for Research Inspiration in STEM Mentorship, or PRISM, is a brand-new high school mentorship program that matches students with a graduate student mentor from the University of Arizona. Students and their mentor engage together in authentic research that answers a scientific or engineering problem. PRISM was created with the understanding that it can be challenging for high school students to do research. PRISM offers the ability to access lab space, scientific equipment, knowledge, and valuable mentorship. Title I and rural schools are prioritized in PRISM involvement.

PRISM works with the University of Arizona Office of Societal Impact to recruit graduate students from all disciplines to become mentors. Students meet with their mentors once a week on the UA campus or virtually to write a research plan, conduct research, and develop a presentation to give to the community at the PRISM Symposium. Mentors receive support from the Office of Societal Impact on developing empathetic mentorship skills and professional development.

Living The Best Version Of Yourself…While Reaching For The Stars – Stacey Weiss

By Cynthia Blockburger, Lindsey Intern, SARSEF

Hello again, it’s me, Cynthia Blockburger. This interview highlights Professor Stacey Weiss of University of Puget Sound and how she envisions the core of mentoring as “living the best version of yourself…while reaching for the stars.” I must begin with how amazing Stacey is, not only as a mentor for STAR Lab (Students Taking Advantage of Research) but also for her joy and passion for supporting students as whole people inside and outside of science. As a student and now science teacher in K-12 education, I know firsthand how beneficial it was to have a mentor who believed in me and who I had the potential to become. Professor Stacey Weiss is that unique individual who mentors and guides students in exploring field and lab research with unquestionable joy and exuberant outcomes as they gain ownership of their work. Stacey told me, “I want to instill confidence and develop passion; I want to encourage students to take ownership of and pride in their work; and I want to do this while leading with kindness and support.”

In addition, Stacey is the recipient of the esteemed 2023 Lynwood W. Swanson Scientific Research Award by the M.J. Murdock Charitable Trust.

I asked Stacey about her first experience working with the STAR Lab.

I began mentoring with STAR Lab in 2021, working with a wonderful student, Jeronimo (Jerry) Barela, from Catalina Foothills High School. Since I am in Washington State, all my mentoring has been done remotely, and we have relied heavily on the wonderful support provided by SARSEF staff and STAR Lab graduate students. I met with Jerry weekly via Zoom (who could have imagined this, pre-pandemic! I suppose some good came from it all…), where we discussed the context for the work, experimental design, specific methodologies, his progress, and planning our to-do list for the upcoming week. Cecilia, A STAR Lab graduate student, typically joined our Zoom calls. She and other staff would help prepare the materials Jerry needed and demonstrate the techniques to him when he was in the lab. It was quite the team effort! I came away incredibly impressed by the program that SARSEF has created – the resources, organizational structure, and other supports (e.g., weekly meetings with undergraduate facilitators) make this program a transformational experience not only for the mentees but also for the undergraduate and graduate students that assist along the way.

Mentors and students in STAR Lab continue to prepare the way for future research in all fields of STEM. When I asked Stacey in what ways scientific mentorship has impacted her practice and mentoring with the STAR Lab program, she said, I have had a variety of mentors with a variety of mentoring styles. I have tried, over the years, to develop a mentoring style that pulls the best bits from all of them. I began conducting independent, mentored research as an undergraduate student. I was nervous and lacked confidence, but my mentors clearly had trust in me and my abilities, and this helped me push forward in the field. Another mentor was great at personalizing his mentoring approach to the needs of his mentees and encouraging us to find and follow our own passion in science. Another emphasized the importance of community, kindness, and diversity of lived experiences in science. As a STAR Lab mentor, I hope to bring these kinds of growth experiences to Southern Arizona high school students.

I asked about Stacey’s most recent project with STAR Lab, and how it has impacted herself and her students. She said that her research team has identified a handful of symbiotic bacteria that provide antifungal protection to their animal host.

My current STAR Lab students are working with the bacteria to identify the mechanism of antifungal action. The pace of research is often slower than students expect, and a perceived lack of progress can be frustrating for them. I emphasize to students that this is typical, especially when developing new protocols and techniques. My emphasis is not just on imparting knowledge but on nurturing the potential within each student. So, “reaching for the stars” may mean very different things to different students.

I was curious to know how Stacey would describe her experience in field research before working with STAR Lab. When asked, Stacey smiled and stated, “I love fieldwork.“

It is definitely what got me hooked into the field of biology! It is empowering to be surrounded by nature and just observe. Observe and generate questions about the natural world. And then figure out how to scientifically address them! Although I have done fieldwork in a variety of places, the one that keeps drawing me back is the Chiricahua Mountains in SE Arizona (for longer than I’d like to admit (30-ish years!)). This mountain is part of the Madrean “sky islands” – an archipelago of mountain islands surrounded by desert seas. The biodiversity here is incredible! I first went there as an undergraduate student from UCLA, and I have been returning annually throughout my professional career. My work is based out of the American Museum of Natural History’s Southwestern Research Station, and I have brought dozens of undergraduate students there with me over the years. I love exposing them to this place that was so transformational in my life. While we are there, we often interact with high school groups that come through the area, including a group from Tucson High Magnet School. That is actually how I got connected to SARSEF and STAR Lab. The previous Director of Research, Margaret Wilch, and I met there almost 20 years ago. I worked with her THMS students over the years. When she retired from teaching and moved to SARSEF, I was delighted to be able to support the program by serving as a remote mentor for STAR Lab students.

Wow, I told you Professor Stacey Weiss is amazing. Her research is as marvelous as our Arizona sunsets…astonishing. So, I wanted to know, as I’m sure you do too, where she sees her work expanding as a faculty member and mentor working with students?

I am trained as a behavioral ecologist, so the microbial work that I am doing now is quite new to me. I hope to continue to learn and develop modern microbial ecology techniques to address questions about the function of wild microbiomes and their effect on their animal hosts. My immediate aims are twofold: 1) I hope to examine interactions between the microbiome and ecoimmunology of free-ranging lizards, and 2) I want to examine intersections between microbial and behavioral ecology by thinking about how lizard behavior (diet, sociality, mating, etc.) affects and is affected by their microbiome.

Tune in for What’s Next with Professor Stacey Weiss. Her research and collaboration with STAR Lab continues. We love her journey, “Living the best version of yourself – while reaching for the stars.”

Finding a connection between your unique self and what you can offer your community can lead to a rewarding career. I discovered I was driven to understand how things worked, which made me the curious student in class who was frequently asking questions.

Through Sonora Quest’s collaboration with SARSEF, I now know the importance of sharing my journey in STEM (science, technology, engineering, and math) to encourage future students who share in my curiosity and want to join the STEM journey!

I am originally from Santo Domingo, Dominican Republic. We moved and I grew up in the Foothills of North Carolina (GO Tarheels!) in a single-parent home. My mom worked full-time as well as two other part-time jobs while providing for my younger brother and me.

In middle school, I remember being intrigued by the stepped approach to arriving at a scientific conclusion: observation, question, hypothesis, prediction, test, analysis, and iteration. Even though my mother’s background was not in STEM, she helped cultivate my enthusiasm for science. I remember she always took a genuine interest in my homework and experiments. If I failed, she encouraged me to try again. She believed in me and my ability to figure things out. My mother motivated me with her interests in my studies, which inspired me to explore more and focus on my future in STEM.

My freshman year I majored in Biology at the University of North Carolina Greensboro. Along the way, I learned about a career path in Nuclear Medicine Technology, a science field that uses radiopharmaceuticals to evaluate organ function and structure. In 2009, I graduated from Manhattan College with a BS in Radiological and Health Sciences with a major in Nuclear Medicine Technology and Concentration in Health Administration. With my degree, I became a Nuclear Medicine PET/CT Technologist serving on the frontlines of healthcare in New York’s Upper East Side at Memorial Sloan Kettering Cancer Center. There I experienced first-hand how delicate life is and learned the importance of providing exceptional patient care.

Over time I developed an interest in combining data with healthcare to contribute to improving quality care outcomes, which motivated me to obtain my MBA in Managerial Analytics from Mercy College. After graduation, my husband and I moved to Arizona, and I pursued a career at Sonora Quest Laboratories/Laboratory Sciences of Arizona (SQL/LSA)—one of the largest laboratory networks in the nation—as a Clinical Informatics Specialist.

I am proud to be a part of a company that brings such valuable and critical services to the community and humbled by the diligence and hard work the team demonstrates every day. Our President & CEO Dave Dexter says that the lab is at the epicenter of healthcare, and I’ve seen it firsthand. Our work makes a significant difference in people’s lives.

I know I am a valued member of the SQL/LSA family. I am extremely grateful for all the creative experiences I have been a part of over the last four years and the support of my leaders along the way. I have led projects for the Population Health and Innovation Teams and have facilitated research & development of our analytics solution, AIMTM (Actionable Insights Management). Today, I am a Program Manager, contributing to the long-term effectiveness and execution of strategic initiatives across our organization. I am so appreciative for my STEM journey, which led me to this rewarding career that allows me to be a supportive mother, just like my mother was to me.

Do you have a child in your life who shares a deep curiosity in STEM? Be their champion! Would you consider giving your time and resources to help non-profit organizations like SARSEF (https://sarsef.org/). Your engagement could profoundly impact someone’s life and help shape a great future for humanity.
