Since childhood, my curiosity about science, along with the encouragement of my teachers and my good performance in physics, chemistry, and mathematics classes during high school, have been influential factors inspiring me to pursue a career in the engineering field.

In my current role, I teach electronic circuits to engineering students, helping them understand how these systems work. Moreover, I guide master’s and doctoral students in my research domain, which focuses on microelectronics, particularly semiconductor material synthesis, device fabrication processes, and the application of sensors and photovoltaic devices.

My greatest achievement is my journey: overcoming the challenges of being raised in a small town in northeastern Brazil, where higher education was not common. My parents lacked higher education. My journey to São Paulo and my completion of a PhD in engineering are my proudest accomplishments.

I believe my greatest challenge has been entering and pursuing a career in the field of engineering, a field traditionally dominated by men. As a woman, I continually face the need to demonstrate my capabilities, which can be exhausting. This demands determination and resilience to deal with biases and stereotypes. I have overcome this challenge by seeking out supportive networks, advocating for gender diversity in STEM fields, and focusing on my passion for engineering to drive me forward.

My advice for young girls or women considering a career in STEM is to believe in yourself and your abilities. Don’t let stereotypes or societal expectations deter you from pursuing your dreams. Embrace challenges as opportunities for growth, seek out mentors and supportive networks, and don’t be afraid to ask questions or seek help when needed.

In my classes and other activities, I strive to empower female students, guiding them to overcome challenges and persist in their studies. Additionally, I seize every opportunity to discuss with male students the significance of embracing diversity and fostering inclusivity within STEM fields. My goal is to leave a legacy of positive influence, motivating others to pursue their passions and create meaningful change in their communities and beyond.
