Key research interests include CMB polarimetry, weak gravitational lensing, galactic dust composition, and the design of stratospheric observatories. Fraisse has led contributions to the SPIDER and CMB-S4 projects, advancing instrumentation for detecting primordial gravitational waves and characterizing cosmic foregrounds.

His recent work emphasizes improving data retrieval from high-altitude balloons and optimizing observational strategies for suborbital telescopes. Publications span technical advancements (e.g., TES arrays, in-flight monitoring) and cosmological analyses using Planck and SPIDER datasets.

Research collaborations include the SuperBIT telescope (commissioned in 2019), enabling diffraction-limited visible-to-near-UV imaging from stratospheric balloons, and refining CMB power spectrum estimation methods for future surveys.
