TITLE:  A hybrid inverse source problem for radiative transport

ABSTRACT:  The radiative transport equation (RTE) is a model for light propagation inside a scattering medium. A classic inverse problem for the RTE is as follows.  Suppose we have an object where light propagation is modeled by the RTE, which contains a source of light. Given the ability to measure light intensity on the boundary, can we recover the light source exactly? In this talk I will give a brief introduction to the RTE and its inverse source problem, and discuss recent work on improving the stability of the problem using so-called hybrid methods. This is joint work with John Schotland and Guillaume Bal.

About the Book Picking Cotton:

Please note that the following book carries a trigger warning: The content deals with an account of a sexual assault and may be triggering to some people.

Jennifer Thompson was raped at knifepoint by a man who broke into her apartment while she slept. She was able to escape and eventually positively identified Ronald Cotton as her attacker. Ronald insisted that she was mistaken-- but Jennifer's positive identification was the compelling evidence that put him behind bars. After eleven years, Ronald was allowed to take a DNA test that proved his innocence. He was released after serving more than a decade in prison for a crime he never committed. Two years later, Jennifer and Ronald met face-to-face-- and forged an unlikely friendship that changed both of their lives.

In their own words, Jennifer and Ronald unfold the harrowing details of their tragedy, and they challenge our ideas of memory and judgment while demonstrating the profound nature of human grace and the healing power of forgiveness.

Physics and Astronomy Colloquium: Physics and Computation

There is a deep connection between Physics and Computation. Indeed, any computation can be represented as a physical process. In 1981, Richard Feynman rasied some provocative question in connection to the simulation of physical phenomena using a special device called a "Quantum Computer". Such a device was intended to mimic physical processes exactly the same as Nature, and thus shared those "spooky" features of quantum physics. Remars coming from such an influential figure generated widespread interest in these ideas, and today, more than three decades after, there are still open questions. What kind of physical phenomena can be mimicked? How? And what are its limitations? I will address these questions in the broader context of what is currently known as quantum information science.
