Congratulations to Lakshya Gangwar for receiving the 2026 Pui Best Dissertation Award! 🌟
Advised by Professor John Bischof, Lakshya’s dissertation tackled one of the hardest problems in cryobiology: scaling vitrification and nanowarming to human-organ volumes. His work demonstrated the largest organ vitrification reported to date — a porcine liver approximately the size of a human organ — along with the largest physical systems vitrified (3 liters) and nanowarmed (2 liters).
These breakthroughs help lay the foundation for future organ banking and transplantation, and reflect the University of Minnesota Mechanical Engineering department’s exemplary heat transfer legacy applied to complex biological systems. ❄️🔬
