<p>My research probes the <strong>quark-gluon plasma (QGP)</strong>, the primordial state of matter that filled the Universe microseconds after the Big Bang. By colliding heavy nuclei at nearly the speed of light, we recreate tiny droplets of this "quark soup" and study its properties, such as its viscosity, its speed of sound and how it flows collectively. The same collisions can also be used to image the shapes of the colliding atomic nuclei.</p>

<p class="rc-text">A collision's particle spectrum changes in two ways: the total number of particles, and its tilt. Only the tilt is radial flow. We show that the number part just shifts v₀(pT) by a constant, so its shape carries the physics and its zero crossing does not.</p>
