Subject: Live Performance, Singular Value Decomposition, Arts at CERN/IARI


It is my great pleasure to invite everyone to this experimental live
performance emerging from a collaboration between Arts at CERN, the
official arts program of the European Organization for Nuclear
Research (CERN) and the Integrated Arts Research Initiative (IARI) at
the Spencer Museum of Art at the University of Kansas (KU) that will
include a live dancer, Vinson Fraley, and musician, Earl Maneein,
layered with video footage from CERN that has been manipulated by
mathematical techniques used in quantum mechanics.

The performance - titled "Singular Value Decomposition" - is grounded
in research by Agnieszka Miedlar, IARI faculty fellow and assistant
professor of mathematics; Daniel Tapia Takaki, associate professor of
physics & astronomy; Clint Hurshman, IARI graduate fellow and student
of philosophy; Olivia Johnson, IARI undergraduate fellow and student
of mathematics and dance; and Janet Biggs, a New York-based video
installation artist. Joey Orr, the Spencer Museum's curator for
research, has guided the collaboration in the production of new work
at the boundaries of science and visual art.

Hope to see many of you joining us!

Subject: Research Associate Positions, Edinburgh


Two postdoctoral positions are now available at the University of
Edinburgh and Heriot-Watt University. The aim of the project is to
develop a new mathematical and computational framework to solve
challenging inverse problems related to low-photon imaging, with
special attention to new quantum-enhanced imaging technologies that
exploit the quantum nature of light in order to dramatically advance
imaging sciences. The framework will be rooted in the Bayesian
statistical paradigm and combine modern ideas from applied analysis,
high-dimensional computational statistics, and machine learning. The
project will be developed in partnership with the Heriot-Watt
Institute for Sensors, Signals, and Systems, and in close
collaboration with the UK Quantum Technology Hub in Quantum Enhanced
Imaging, ENS Paris Saclay, the University of Illinois, and the
industrial partner Leonardo UK. The project is funded by UKRI EPSRC
(EP/V006134/1 and EP/V006177/1).

This is a highly multidisciplinary project. We are looking to hire
Postdoctoral Research Associates with either:
1. A strong mathematical profile to lead the theoretical and
methodological aspects of the project, with experience in the
analysis of stochastic optimization or sampling algorithms.
2. A strong computational imaging profile to lead the computational,
algorithmic, imaging, and application-specific aspects of the
project.

Both positions are 36-month fixed-term contracts. One will be employed
by the School of Mathematics at the University of Edinburgh, and the
other one by the School of Mathematical and Computer Sciences at
Heriot-Watt University.
