Dr. Juhi Raj is shaping the future of medical imaging by advancing PET scan technology to serve women's health better. At the University of Pennsylvania, she brings together the precision of physics, the power of artificial intelligence, and deep clinical understanding to develop innovative imaging algorithms that improve diagnostic clarity and speed.
Building on this personal experience, her motivation is deeply personal. Watching her aunt fight breast cancer opened her eyes to the critical role of timely and accurate diagnostics, not just access to doctors. She realized that technology, when thoughtfully designed, can become a lifeline.
Today, Dr. Raj is committed to ensuring that advanced imaging tools are both powerful, equitable, and accessible. Her work bridges the gap between high-tech innovation and real-world application, helping to bring life-saving diagnostics to where they can make the most significant difference.
Pursuing Science Across Continents
Juhi Raj's scientific journey began at Christ University in Bangalore, where she completed her undergraduate and master's degrees in physics. Here, she first nurtured her passion for research and built a strong foundation in scientific thinking and problem-solving.
She deepened that curiosity through an early research internship at the Indian Space Research Organization, where she gained hands-on experience in simulating particle detectors and encountered the complexity and scale of real-world scientific challenges.
Building on her early experiences, and eager to explore fundamental physics on a deeper level, she pursued a Ph.D. at Jagiellonian University in Poland in the Jagiellonian-PET collaboration with the mentorship of Prof. Pawel Moskal, one of the leading figures in positronium physics and antimatter studies.
Her work contributed to advancing the sensitivity of symmetry tests and laid the groundwork for the computational techniques she would later apply to clinical imaging.
Advancing Clinical Imaging with AI
Raj is pioneering physics-informed AI models designed to transform PET imaging. She is delivering high-quality, lower-dose scans with improved efficiency and affordability.
She aims to work with the world's leading scientific institutions. She is committed to global impact and actively engages in scientific theatres and interdisciplinary collaborations to remain at the forefront of AI medical imaging.
This mission is not only scientific but also deeply personal for Raj. "Reminded that the failure to translate medical innovation into practice cost a loved one," she says, "I carry that memory as a flame—one that fuels my commitment to closing critical gaps in women's health on a global scale."
Cancer, Collaboration, and Change
Raised in India's highly dynamic medical research environment, Dr. Juhi Raj has supported and mentored early-career scientists pursuing cancer diagnostics and care research.
With extensive exposure to cross-institutional training and international conferences and experience as a dedicated reviewer for journals in nuclear medicine and medical physics, Dr. Raj firmly believes that the United States is the leading global contributor to imaging research, particularly in advancing diagnostic technologies.
Building on that belief, she now brings the same energy to her work in the United States. Drawing on her fast-paced and dynamic research experiences in India, she now strives to set the pace in the United States by leading public outreach efforts in science communication, HPV education, and initiatives that connect research efforts more directly to cancer prevention and treatment.
Global Collaborations and Recognitions
Dr. Juhi Raj has presented her work at over 15 international conferences, including IEEE NSS MIC, Fully3D, and DISCRETE. Researchers have widely cited her peer-reviewed publications in Physics in Medicine and Biology and Nature Communications journals. These have contributed to collaborative, multi-institutional research initiatives focused on improving access to diagnostics in developed and developing countries.
By contributing to multidisciplinary efforts and maintaining active involvement in leading technical conferences, Dr. Raj remains at the forefront of innovation in imaging research by advancing technologies that prioritize accessibility and clinical impact.
Moving Imaging into Equity
Dr. Raj's exposure to various countries and research settings has driven her mission to make PET imaging more scalable and affordable. With extensive practical experience addressing technical challenges across the medical imaging supply chain, she continues to solve problems in this space, drawing on a lifetime of medical research expertise.
These insights guide Dr. Raj in building environments where innovation leads to practical, achievable outcomes.
Through her contributions spanning science, mentorship, humanity, and innovation, Dr. Juhi Raj is advancing the frontiers of medical imaging and redefining its global purpose and reach by aligning technology with accessibility and patient-centered care.
