# Nigel J. T. Smith

Nigel Smith is a British Canadian astroparticle physicist and the Executive Director and CEO at TRIUMF.

## Education

Nigel Smith obtained both his undergraduate and graduate degree in physics and astrophysics from the University of Leeds in the United Kingdom. He studied cosmic and gamma rays for his PhD and undertook experimental research in Antarctica where he was the sole operator of the SPASE gamma ray telescope at the South Pole. In 1998, he became the first Briton to successfully ‘winter-over’ at the South Pole as the sole operator of a telescope during his study of astronomical sources of ultra-high energy gamma rays.

## Career

Smith was appointed the Executive Director and CEO of TRIUMF in 2021. He leads TRIUMF and manages government and international relations, strategic growth of the research programme and facility infrastructure, and the development of the team and internal processes.
Prior to working at TRIUMF, between 2009 and 2021 Smith was the Executive Director at SNOLAB, developing the capabilities of Canada’s deep underground research facility. SNOLAB is 2070m underground in the Vale Creighton mine near Sudbury, Ontario, and hosts searches for dark matter and studies of neutrino properties.
Throughout his career, Smith has worked in extreme environments to pursue his research. He has led multiple teams at facilities internationally and international research collaborations. At the STFC Rutherford Appleton Laboratory, he led the international collaboration that pioneered the use of liquid xenon for dark matter studies through the construction of the ZEPLIN-I and ZEPLIN-II projects. In 1989, he was one of the first to enter a new U.K. deep underground laboratory at the Boulby Mine, on the Cleveland/North Yorkshire border, where he searched for WIMPS 1100m underground.

## Awards and honours

In 2010, Smith is chartered physicist in both Canada and the U.K. a member of the Canadian Association of Physics, the Institute of Physics, and a fellow at the Royal Astronomical Society. He was awarded the U.S Congressional medal and winter-over bar for his Antarctic duties in 1988.
