Mixing due to cutting-and-shuffling is studied at a fundamental level using 2D mappings known as Piecewise Isometries (PWI) which can create beautiful mixing patterns. The PWI studied here splits a hemispherical shell (HS) into four curved triangular pieces that are rearranged to make a shuffled HS. Applying the PWI repeatedly... View the visualization.

I present an interactive visualization for the US Congress members' ideology. The data used are ideology scores of US Congress members 1789-2015. The ideology scores are quantified from the Congress members' voting records using the DW-NOMINATE method, which puts Congress members with similar voting patterns closer together. This interactive visualization... View the visualization.

Using ab initio calculations, we discovered a quasi two-dimensional copper–bismuth nano sheet, which we call cubine. According to our predictions, single layers of cubine can be isolated from the recently reported high-pressure CuBi bulk material at an extremely low energetic cost, comparable to values to separate single layers of graphene...

A fractal is created by a Piecewise Isometry (PWI) which cuts a 2D object into pieces and rearranges those pieces to recreate the original object in a scrambled form. The PWI studied here splits a hemispherical shell into four pieces along cutting lines and rearranges them into a shuffled hemisphere.... View the visualization.

Three-dimensional imaging techniques have been widely used in both industry and academia. Time-of-flight (ToF) sensors offer a promising method of 3D imaging due to compact size and low complexity. However, state-of-the-art ToF sensors only have depth resolutions of centimeters due to limitations in the modulation frequencies that can be used.... View the visualization.

Over half of millennials believe gender is a spectrum, yet our models remain stuck in binary logic. As health researchers and practitioners, we can create schematics that provide information, connect concepts, and actively engage youth in their own health, on their terms. We created an interactive map as a visual... View the visualization.

This visualization shows two-photon imaging of GCamp6f in hippocampal pyramidal neurons as a mouse navigates a virtual reality maze. These techniques give us an indirect measure of activity in neurons or small compartments of neurons in an awake, behaving animal. The hippocampus has been well characterized as playing an essential... View the visualization.

Firefly is an interactive tool that allows users to fly through any 3 dimensional dataset by rendering it on-the-fly. Here we present simulation data created as part of the FIRE galaxy formation collaboration. Interactively exploring data generates powerful intuition and helps one isolate regions of interest in the data using... View the visualization.

Levitation—the rising or hovering of an object in apparent defiance of gravity—is a captivating phenomenon with a wide range of applications. In this visualization, we demonstrate our newly discovered form of fluid dynamical levitation of small particles that may be 10, 100, or even 1000 times as dense as the... View the visualization.

Massive Black Holes, millions to billions of times more massive than our sun, exist in the centers of most galaxies. However, the formation and evolution of these objects through accretion of gas and mergers with other black holes is still a great mystery. LISA, a future space-based gravitational wave detector,...

Portrait of the Galaxy is a snapshot from a 3d rendering of a galaxy that displays the complex structure of the gas component of the simulation. This gas component is difficult to observe in real telescopes but with visualizations and simulations like these we can begin to understand how to... View the visualization.

This is a movie of three galaxy formation simulations I ran as part of my research. The color of each pixel represents the temperature of the gas (blue for cold and green for hot) and the brightness of each pixel represents the density (dim for low density bright for high...

This is a visualization of an event reconstructed in CMS HGCal. This event is consist of 10 pions with a transverse momentum of 35 GeV. The reconstruction algorithm groups all valid energy deposits (hits) into clusters, each incoming particle having one or a few corresponding clusters, so that the energy... View the visualization.

Psychometric analyses can help illuminate how people approach clinical tests. To understand how health literacy (i.e., literacy for health information) might lead to biased assessment of emotional distress, we examined the psychometric properties of anxiety and depression questionnaires, using differential item functioning (DIF) analysis. Items were flagged for DIF if... View the visualization.

Our research group is currently working to develop the first cross-culturally validated household water insecurity scale. In order to do this, we have partnered with numerous collaborators to implement the survey in diverse ecological settings. As part of the survey, participants are asked to recall how long it takes to... View the visualization.

These images show how the Facebook networks of 121 LGBTQ youth (Mage = 24.13 years) differ depending on how “out” these young people are about their identities. Using cluster analysis of survey data, we found LGBTQ youth managed outness in one of four ways: high overall outness (63.82%), low overall... View the visualization.

Typing is a complex process which draws on both cognitive and motor skills. By visualizing holistic trends in the typing process, TypeShift aims to elucidate the often-noisy information signals that are used to represent typing patterns. The importance of a tool such as TypeShift is that it can help answer... View the visualization.
