Growing up in a family where every woman was a mathematics teacher or professor, I was immersed in a culture that valued logic, learning, and curiosity. Over time, my fascination with science and technology only deepened. When choosing a PhD topic, I intentionally stepped beyond theory to explore how fundamental science could be applied to real-world challenges. That’s what led me to the semiconductor industry — an ideal space where microelectronic innovation directly powers our everyday lives.

In my current role, I lead the development of software solutions for cutting-edge technologies, acting as a connector across engineering, marketing, and sales. My focus is not only technical but also people-driven, ensuring collaboration, clarity, and continuous progress. Over the years, I’ve learned that being truly customer-centric and adaptable is essential to building solutions that meet both market and human needs.

Among my proudest accomplishments is pursuing an Executive MBA while managing a full-time job and raising three children. This journey has been one of growth — broadening my perspective, sharpening my leadership skills, and connecting me with a global network of inspiring professionals. It stands as a testament to the power of intentional time management and the pursuit of excellence through lifelong learning.

One of the greatest challenges I’ve faced has been balancing my career with motherhood; raising young children while pursuing an ambitious professional path requires immense discipline and support. Today, I use my experience to mentor young women navigating similar journeys.

To girls and women considering a career in STEM: go for it. This field offers endless opportunities to make a real impact, solve important problems, and be part of building the future. Seek out mentors — especially female role models or supportive allies — and never doubt that your voice and ideas belong here.

I hope my legacy will be one of purpose-driven impact: contributing to innovation, advocating for inclusion, and helping open doors for others. I’m especially proud of my advocacy for girls in STEM, including my work with Siemens and partner organizations to expand access, visibility, and mentorship in science and engineering.

I believe we’re living in a time of major change, when technologies like AI are bringing science, innovation, and human values together in ways that are shaping the future like never before. As professionals in STEM, we have both the responsibility and the privilege to shape a future that is not only innovative but also inclusive and sustainable.
