Stephora Cesar Alberi, a rising star in the field of biotechnology, is driven by a deeply personal mission: to leverage the power of computer vision to accelerate medical diagnostics and drug discovery, particularly in underserved communities. Her journey, rooted in a childhood shaped by both opportunity and hardship, is now leading her to Cambridge University this autumn, where she will pursue a PhD focused on enhancing microscopy through artificial intelligence.
Computer vision, a branch of AI that allows machines to “see” and interpret images, holds immense potential for revolutionizing healthcare, especially in regions facing limited resources. Alberi believes this technology can be a game-changer in the fight against infectious diseases like malaria and cholera, conditions that have directly impacted her family in Haiti. “My research is motivated by family members in Haiti who were affected by the 2010 cholera outbreak and are now facing a malaria epidemic,” she explains. “I believe computer vision can accelerate diagnostics and drug discovery for infectious diseases in vulnerable countries in the Global South.”
Alberi’s path to this groundbreaking research wasn’t always clear. Born in Guadeloupe and raised in the United States after her family relocated when she was three years classic, she experienced significant upheaval early in life. The loss of her father as an infant and her parents’ separation created financial strain, and her family relied on the support of older sisters and her mother’s dedication as a nursing assistant. A pivotal moment came when her eldest sister, after battling cancer in the Dominican Republic following the devastating 2010 Haiti earthquake, returned to Haiti for treatment and tragically passed away at a young age. This loss fueled Alberi’s determination to excel academically and find a way to make a tangible difference.
Initially drawn to cybersecurity during her undergraduate studies at Salisbury University, Alberi soon discovered her true passion lay in the burgeoning field of artificial intelligence. A National Science Foundation Research Experiences for Undergraduates project introduced her to deep learning and image processing, sparking an immediate fascination. She honed her skills working on a facial emotion recognition model with Dr. Shuangquan Wang, but realized her university lacked the resources to further her research. A pivotal recommendation from her advisor, Dr. Margaret Sebastian, led her to a study abroad opportunity at the University of Tartu in Estonia, where she explored computer vision applications in autonomous systems, including Estonia’s first lunar rover project.
From Space Rovers to Microscopic Worlds
Her experience in Estonia solidified Alberi’s commitment to computer vision. Working with Quazi Saimoon Islam, CEO of the KuupKulgur project, and Ric Dengel, she analyzed feature detectors and experimented with Superpoint, a framework for identifying key points in images, contributing to the development of 3D reconstructions for lunar rover navigation. This work, funded by a Boren Scholarship – which requires a commitment to national security employment after graduation – allowed her to apply cutting-edge techniques to real-world challenges.
Now, Alberi is preparing to apply these skills to a new frontier: enhancing microscopy. Her PhD research will focus on improving image processing techniques to accelerate the identification of solutions to biomedical problems, such as antimicrobial resistance. She envisions a future where computer vision-equipped microscopes are accessible and affordable in the Global South, enabling rapid and accurate diagnoses of infectious diseases. This is particularly crucial in regions like Haiti, where access to advanced medical technology is limited.
The Promise of AI-Powered Diagnostics
The potential impact of Alberi’s work extends far beyond Haiti. According to the Centers for Disease Control and Prevention (CDC), the 2010 cholera outbreak in Haiti was one of the largest in recent history, highlighting the urgent need for improved diagnostic capabilities. Similarly, malaria remains a significant public health threat in many parts of the world, with the World Health Organization (WHO) reporting nearly 250 million cases in 2022. Computer vision offers a powerful tool to address these challenges by automating image analysis, reducing diagnostic delays, and improving accuracy.
Alberi’s story is a testament to the power of personal experience to drive scientific innovation. Her dedication to making a difference, combined with her expertise in computer vision, positions her as a rising leader in the field of global health. As she embarks on her PhD at Cambridge, the world will be watching to see how her work transforms the landscape of medical diagnostics and brings hope to vulnerable communities around the globe.
The future of computer vision in healthcare is bright, and Alberi’s research represents a significant step towards realizing its full potential. Further advancements in AI and machine learning, coupled with increased investment in accessible technology, will be crucial to ensuring that these innovations benefit all populations, regardless of their geographic location or socioeconomic status.
