Biography
Insects well-adapted interactions with abiotic and biotic surroundings offer inspiration for innovative engineering designs and concepts. One of the primary abiotic components in nature is fluids. In air, water, or in between, the small sizes of insects contend with multiple fluid forces. Through morphological and behavioral adaptations, insects have found numerous ways of foraging, evading, communicating, and feeding in dynamic fluid environments. Roh's main research interest is to study these adaptations and apply the findings to different engineering disciplines, such as agricultural, biomedical, and aeronautical engineering.

Teaching Interests
Professor Roh teaches students the fundamentals of fluid dynamics and how it integrates to different aspects of biology. The physical rules governing fluid flow play an important role as a selective pressure for evolution and as a conveyer of material and information both inside and outside of every organism. He communicates important discoveries in fluid dynamics and tells the stories of important biological principles that are made more clear in the light of fluid dynamics. Furthermore, in contending with a fluid environment, biological organisms evolved impressive engineering marvels using squishy and sticky material. In his other course, comparative biomechanics, he further explores biological diversity through the lens of both solid and fluid mechanics. In both courses, fundamental physics governing fluid and solid mechanics are emphasized, as well as the modern experimental technique.
His courses include:
- BEE 3310/5310 Bio-Fluid Mechanics
- BEE 4560/6560 Ecological Mechanics
