144. Dr. Elizabeth Mendes (Elizabeth the Scientist); Pediatric Cancer Research; Molecular Biology.

In this episode of Ordinarily Extraordinary: Conversations with Women in STEM, host Kathy Nelson sits down with Dr. Elizabeth Mendes, a newly minted PhD and postdoctoral researcher whose work focuses on rare and aggressive pediatric cancers.

Dr. Mendes recently completed her PhD at Duke University, where she spent over five years researching rhabdomyosarcoma, a rare childhood soft-tissue cancer. Her goal: identify new biological targets that could one day lead to better, more effective treatments for children. Kathy and Liz explore not only the science behind pediatric cancer research, but also the deeply human reasons that drive this work.

What We Talk About in This Episode

• What pediatric sarcomas are—and why they’re so challenging to treat
  Liz breaks down complex cancer biology in an approachable way, explaining how sarcomas differ from more common cancers and why their ability to “change form” makes them particularly dangerous.
• A non-traditional path into science
  From archaeology and zoology to teaching middle school math and science, Liz shares how curiosity—and not a straight line—ultimately led her to molecular biology, cancer research, and a PhD.
• Choosing pediatric cancer research
  Liz explains why she decided to focus on rare childhood cancers that receive less funding but have devastating outcomes—and how personal experiences with cancer shaped that decision.
• Science close to the patient
  We discuss the importance (and rarity) of researchers interacting directly with patients, families, and clinicians—and how those experiences fundamentally change how science is done.
• Life after the PhD: postdocs, fellowships, and moving to the UK
  Liz shares what it’s like to finish a PhD, move countries, start a new research position, and navigate life and work during a major transition.
• Being your whole self in STEM
  From makeup and music to mental health and social media, Liz talks about rejecting outdated stereotypes of what scientists “should” look like—and why authenticity matters for the next generation.
• Representation, mentorship, and science communication
  Liz reflects on why visibility matters, especially for women and first-generation students, and how platforms like social media can help make science more accessible and human.

A Conversation About More Than Science

This episode goes beyond lab work and credentials. It’s a candid conversation about grief, resilience, identity, and the responsibility scientists carry—not just to discovery, but to people. Liz’s story is a powerful reminder that STEM careers don’t require fitting into a mold—and that compassion belongs in science.
