Pursue your passions and interests, and don’t be afraid to seek out help and support when you need it.


I was drawn to my field by a combination of curiosity, passion for discovery, and a desire to contribute to society through advancing knowledge and technology. As a child, I was fascinated by rainbows. Later, I discovered the role that physics, and more specifically optics, played in explaining these magnificent arcs of color. I also realized that with optics, I could both satisfy my curiosity and conduct useful experiments. Additionally, I was fortunate to have the unwavering encouragement of my parents and my family, who have always supported me in my academic and career choices.

As a university professor in physics and chairperson of my physics department, my main activities include teaching undergraduate and graduate courses in physics; conducting research activities; and mentoring and advising students. I also serve on various committees,participate in conferences, and work with colleagues at my university and across the world to advance our collective goals and objectives.

One of my most significant career achievements has been establishing my research laboratory in biophotonics, which focuses on optical engineering, at my university. I have had the privilege of supervising and mentoring numerous graduate students who have gone on to become researchers, consultants, and educators in their own right. The fact that the majority of these students are women makes this accomplishment all the more meaningful; I am proud to have helped empower and inspire the next generation of female scientists.

When I was first starting out 20 years ago, I wish someone had advised me to be more proactive in seeking out opportunities for collaboration and networking. I firmly believe that building relationships with other researchers and educators is incredibly important.

Overall, I feel incredibly fortunate to be able to work in a field that I am passionate about, and to have the opportunity to share my knowledge and expertise with younger generations. I look forward to continuing to contribute to my field in meaningful ways while creating a more inclusive environment for the future of research.

My advice for young girls or women who are considering a career in STEM is, "Surround yourself with people who encourage you, and don't be deterred by any perceived barriers or obstacles."
