I have always been fascinated by learning through a logical and rational approach, where understanding replaces rote memorization. This focus drew me towards mathematics and science. My interest further evolved during my MS and PhD studies, where I became deeply curious about molecular spectroscopy and its connection to understanding various pathophysiological conditions.

Now, I lead a Raman research group focused on developing advanced optical systems for deep-tissue analysis and point-of-care screening/monitoring. A significant part of my role involves mentoring students and postdoctoral researchers, teaching, and writing grant proposals to secure research funding.

As a researcher, I am passionate about translating scientific research into tangible products. In that context, my postdoctoral work at Vanderbilt with Professor Anita Mahadevan-Jansen — which focused on understanding dynamic molecular changes in-vivo — stands out. Additionally, I am particularly proud of helping to develop Diffuse Resonance Raman Spectroscopy (DRRS), a technique for non-invasively characterizing red blood cells, as it has the potential for real-world applications.

One of the biggest challenges I have faced is building confidence in my abilities. I overcame this by actively seeking support and encouragement from mentors and colleagues, which has helped me recognize my strengths.

My advice to young women considering STEM: Embrace challenges boldly; remember that temporary setbacks become powerful lessons that ultimately strengthen your career journey. Believe in yourself, and don’t let self-doubt cause you to miss opportunities. Give your best to whichever path you choose and keep going while continuing to learn.

Looking ahead, I aim to develop innovative optical technologies and methodologies that advance scientific understanding while directly improving disease diagnosis and monitoring. I hope that my legacy will be marked by inspiring future scientists, fostering an inclusive research environment, and supporting the career advancement of women in STEM.

Science is a collaborative endeavor: Every day I am grateful for the opportunity to work with talented researchers from around the world.
