About

Sahangi P. Dassanayake is a pioneering researcher in space-deployable structures, with a primary focus on in-space assembly technologies for large-aperture antennas. Her most-cited work, "Scalable Concept for Reflector Antenna Assembled in Space" (2024, 3 citations), addresses a critical bottleneck in space engineering: the size constraints imposed by launch vehicle fairings. By proposing a novel design for reflectors assembled directly in orbit, Dassanayake overcomes the limitations of conventional deployable systems, enabling unprecedented aperture sizes for future space missions. Her research emphasizes mass efficiency and geometric optimization, offering a scalable solution that reduces both stowed volume and structural weight. This work has immediate implications for next-generation communication satellites, Earth observation, and deep-space telescopes. Although early in her career, Dassanayake’s contributions represent a paradigm shift in how large space structures are conceived, moving from deployable to constructible architectures. Her findings establish a foundational scaling framework that guides future engineering efforts, positioning her as a rising thought leader in space structural design.
