Job Title: 

Physicists and Astronomers

Job Description: 

Physicists and astronomers conduct research, improve or develop concepts, theories and operational methods concerning matter, space, time, energy, forces and fields and the interrelationship between these physical phenomena. They apply scientific knowledge relating to physics and astronomy in industrial, medical, military or other fields.


Tasks include:

  • conducting research and improving or developing concepts, theories, instrumentation, software and operational methods related to physics and astronomy
  • conducting experiments, tests and analyses on the structure and properties of matter in fields such as mechanics, thermodynamics, electronics, communications, power generation and distribution, aerodynamics, optics and lasers, remote sensing, medicine, sonics, magnetism, and nuclear physics
  • evaluating results of investigations and experiments and expressing conclusions, mainly using mathematical techniques and models
  • applying principles, techniques and processes to develop or improve industrial, medical, military and other practical applications of the principles and techniques of physics or astronomy
  • ensuring, accurate measurement and characterisation of doses of radiation delivered to patients in medical applications of nuclear technology
  • testing, commissioning and evaluating equipment used in applications such as imaging, medical treatment and dosimetry
  • advising and consulting with medical practitioners and other healthcare professionals in optimising the balance between the beneficial and deleterious effects of radiation
  • observing, analysing and interpreting celestial phenomena and developing methods, numerical models and techniques to extend knowledge of fields such as navigation, satellite communication, space exploration, celestial bodies and cosmic radiation
  • maintaining and developing standards and protocols for measurement of physical phenomena and for the use of nuclear technology in industrial and medical applications
  • preparing scientific papers and reports
