IDEX Health & Science is proud to celebrate Elizabeth Bernhardt, PhD, Senior Application Scientist, on her selection for the 2027 SPIE Women in Optics notebook.
This annual publication highlights women across optics, photonics, and STEM who are helping shape the future of science, technology, and innovation. Since 2005, the Women in Optics notebook has showcased inspiring stories from scientists, engineers, researchers, students, and industry leaders around the world, encouraging future generations to explore careers in STEM.
For Bernhardt, the appeal of physics was never just the math.
"When a company has a mechanical problem, they hire a mechanical engineer. If they have an electrical problem, they hire an electrical engineer. If they don't know what their problem is, they hire a physicist."
The quote, from one of her undergraduate mentors and engineer Dr. Yvonne Ng, perfectly captures Bernhardt's approach to science: embracing curiosity, tackling complex challenges, and finding creative paths forward in the face of uncertainty.
"Physics is not just about equations, but about understanding the unknown and finding creative paths forward," said Bernhardt. "I am a proud nerd who strives to be approachable and down-to-earth. I want people to feel comfortable asking questions."
Today, Bernhardt helps customers solve complex life science challenges with our Semrock® optical filters. As a Senior Application Scientist, she works closely with researchers and instrument developers to support applications ranging from fluorescence-guided surgery and cancer diagnostics to diagnostic testing. Her role combines scientific expertise with customer collaboration, helping bring innovative technologies from concept to reality.
Her journey into life science applications is also deeply personal. Following the loss of her father, Bernhardt sought opportunities to contribute to technologies that could improve patient outcomes and advance healthcare innovations. Today, her work supports applications that can have a meaningful impact on the lives of patients, researchers, and healthcare providers around the world.
Beyond her technical contributions, Bernhardt is passionate about science outreach and mentorship. Through volunteer work with Skype a Scientist, she connects directly with students, helping them see how science extends beyond textbooks and into real-world careers. Whether discussing physics, career paths, or the unexpected questions students bring to every conversation, she sees each interaction as an opportunity to make STEM more accessible and approachable.
Bernhardt is also committed to helping others understand that there is no single path to success in science. By speaking openly about her experiences, she hopes to encourage students and young professionals who may question whether they belong in STEM.
One of the recurring themes throughout the Women in Optics notebook is the importance of representation. When students can see scientists and engineers from a range of backgrounds sharing honest accounts of their careers, they gain a clearer view of what is possible for themselves. Bernhardt's story reflects that mission, demonstrating the value of curiosity, perseverance, and seeking support along the way.
Her advice for those considering careers in STEM is simple but powerful: ask for help.
"Someone has likely faced the problem you are dealing with, and their experience can offer guidance."
Looking ahead, Bernhardt hopes her impact extends beyond the technologies she helps develop.
"My hope is to leave a legacy of inspiration, showing that it is possible to succeed in science despite challenges, self-doubt, or feeling like you do not belong."
At IDEX Health & Science, we are proud to celebrate Bernhardt's recognition in the 2027 SPIE Women in Optics notebook and grateful for the expertise, curiosity, and mentorship she brings to our team and the broader optics and photonics community every day.
