Visual and vestibular contributions to the perception and control of dynamics spatial orientation
The primary function of the human vestibular end organ is to provide the central nervous system with information related to the movement of the head, and its orientation with respect to gravity. While angular accelerations are transduced by the semicircular canals, linear gravito-inertial accelerations are transduced by the otoliths. This work consists of two studies that systematically explore how visual and vestibular cues affect the perception and control of dynamic spatial orientation. First, I present a study that investigated vestibular perception and manual control of balance. I show how, when present, Dynamic otolithic cues related to tilt from gravity bias the perception and control of balance in the direction of the gravitational vertical. Dynamic gravitational cues have a nonlinear effect on the threshold for detection of angular acceleration, and on the attenuation of velocity integration of semicircular canal signals in the supine orientation. Next, I present an experiment that extended this paradigm with congruent visual cues, to understand visual-vestibular integration. I show that visual-vestibular integration is dominated by vestibular cues when dynamic gravitational cues are present, and visual cues when they are not. Furthermore, the presence of gravitational cues differentially affects multisensory integration for the perception and control of balance orientation. Together, these studies illuminate how the brain integrates sensory information and produces a sense of spatial orientation, and how this ability is affected by gravity.

The role of miRNAs in circadian biology
Many of the beautiful and intricate textures displayed in smectic liquid crystals are characterized by the set of defects they produce. Merely enforcing the condition that the smectic layers must be equally spaced produces focal conic domains, which may be the most iconic of all smectic textures. Building such textures from purely geometric constraints proves a daunting task. However, the construction of focal conic domains is vastly simplified if we view them as level sets of a null hypersurface in Minkowski space, revealing a hidden Poincaré symmetry.

The addition of chirality to a smectic adds frustration to the system, as layers and twist cannot coexist. Historically, the twist grain boundary phase has been the only solution to this problem. Recently, we have found a new ground state for the chiral Landau-de Gennes free energy. We propose that this hierarchical structure composed of bundles of nested helicoids which assemble themselves into a lattice is a model for the helical nanofilament (B4) phase of bent core liquid crystals.
