I was always fascinated by the intricacies of mathematics and physics, captivated by how they reveal the beauty and logic of the world. This curiosity laid the foundation for my path into science, optics, and precision engineering. My father encouraged me to pursue questions deeply; later, I drew strength and inspiration from mentors and women scientists who showed me what was possible in a field where diverse voices are still growing.

Currently, I design and develop high-precision optical components used in diverse healthcare and industrial applications, including medical imaging, scientific instruments, aviation displays, thermal cameras, and low-vision aids. My work centers on advancing manufacturing techniques to shape complex lenses and mirrors, down to the level of atoms. A primary focus is Single Point Diamond Machining, a subtractive process essential for producing ultra-smooth, geometrically exact optics that other methods often can't match in quality or efficiency.

My broader research goal is to develop a streamlined and affordable process chain for manufacturing these components, so that even small and medium enterprises can contribute to high-end technological innovations. One of the most impactful milestones in my research journey has been the design and development of high-diopter lenses, which have enabled significantly improved vision for individuals with severe impairments. These lenses were also distributed to those in need, making a meaningful difference in their lives and contributing to a broader social cause.

Early in my career, I was often the only woman in the room, which could feel isolating. I overcame this by building a strong support network, seeking mentorship, and staying committed to my purpose. I have learned to transform such challenges into motivation, to push boundaries, stay curious, and advocate for more inclusive spaces in science and engineering. Navigating the dual challenges of technical leadership and underrepresentation as a woman in engineering has been tough but rewarding. I have learned the value of perseverance, strong mentorship, and building a community that uplifts every individual.

To young girls and women considering STEM: Trust your instincts, follow your curiosity, and never underestimate the value of your unique voice. I wish someone had told me early on that you don’t need to have everything figured out: the journey itself will shape you.
