Focal-plane wavefront sensors for direct exoplanet imaging: Theory, simulations and on-sky demonstrations
One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

Mutable Audible – An Operative Ontology of the Sound Image
In his dissertation Gabriel Paiuk explores the variable ways in which what is heard is formed. To address this, he postulates a novel concept of sound image in a post-anthropocentric context in which both mind and material artefacts are instances across which the image occurs, rather than hosts on which…

New imaging technology to assess early drug success
Human and animal cells are very complex: very different chemical processes are going on at the same time, but they are separated from each other because the cells are divided in compartments. These compartments may also have a profound effect on the potential efficacy of therapeutics, because the drug…
