Meet Dev Gupta and Joshua Reljac
“BioBuilder helped me understand the nitty-gritty parts of science. And being able to combine my interest in biology and technology helped propel me forward as a scientist.”
In this inspiring episode of the BioBuilder Podcast, Dev and Joshua, co-founders of the startup AIVON, take listeners through their personal journeys of curiosity, innovation, and social impact. The conversation weaves through their formative experiences with science and technology, their time in the BioBuilderClub, and their ambitious venture into the world of AI-powered healthcare.
🔬 Origins of Scientific Curiosity
Dev recounts how growing up in a science-loving household, with parents and an aunt deeply engaged in the subject, laid the groundwork for his fascination. From tinkering with technology alongside his dad to wondering about disease mechanisms, he developed an early love for biology and engineering. This curiosity eventually led him to Alliance Academy, where he joined the BioBuilder Club, a decision that would define much of his scientific identity.
🧪 The BioBuilder Experience
As part of the BioBuilder program, Dev and his team designed a sustainable biofiltration system that uses genetically engineered bacteria (E. coli, Bacillus subtilis, and Pseudomonas putida) to remove heavy metals from water. The bacteria were enhanced with plasmids encoding metal-detoxifying enzymes and embedded in a biochar-based medium for stability and efficiency. Their modular, scalable filter design bridged biology and engineering in a way that was both educational and impactful. Dev credits BioBuilder for teaching him adaptability, technical rigor, and how to bring abstract ideas to life.
🤝 Collaboration & Discovery
The episode explores how Dev collaborated with peers to develop their project, noting “aha!” moments when the science began to click. The iterative nature of their work, coupled with expert guidance from mentors like Dr. Grace Vezeau and Ms. Caroline Matarrese, helped deepen their understanding of real-world science. Soft skills like communication and teamwork were just as vital as technical prowess, a lesson Dev carries into his startup journey into career paths, possibly through an MD-PhD program.
🚀 Building AIVON and Medisense
Shifting to the theme of innovation, Dev and Joshua introduce their startup AIVON, based in Atlanta. Their flagship product, MediSense, is an AI-powered diagnostic platform that allows users to input symptoms and receive real-time health assessments. The idea was born from the intersection of their scientific training and the urgent need for accessible, intelligent healthcare tools.
They share how conversations with patients, doctors, and mentors shaped MediSense’s design and functionality, emphasizing the importance of user feedback in product development. Their goal is to make fast, affordable, and intelligent diagnostics available to everyone, especially in underserved areas. Despite challenges—from building the tech to managing startup logistics—they remain focused on scaling the product and seeking potential partnerships with hospitals and schools.
