Ravi Sood obtained his PhD in Astrophysics from the Blackett Laboratory, Imperial College,
London. He studies the emission of high energy gamma rays from the Sun and from the Milky Way
galaxy using instruments flown from high altitude balloons from locations in four continents.
In 1979, he took up a lecturing position at Melbourne University (RAAF Academy) where he carried
out investigations into ultra-high energy iron nuclei in cosmic radiation using stratospheric balloons.
He joined UNSW@ADFA in 1986 as a Senior Lecturer and established the High Energy Astrophysics Research
Group in the School of Physics. He was promoted to Associate Professor in 1992, and was the Head of
the School of Physics from 1995 to 2002.
Ravi Sood is the leading expert in stratospheric scientific ballooning in Australia.
Teaching
I have taught Physics at all levels of the undergraduate degree in Australia for 26 years.
In addition, I have supervised several PhD and MSc students. I was awarded the UNSW@ADFA Teaching
Award for excellence in teaching in 2000. Currently, I teach the following courses:
Astrophysics (Honours, Level IV)
Cosmology and Relativistic Astrophysics (Level III)
Navigation and Guidance Physics (Level III)
Space Physics and Astrodynamics (Level I)
I led the development and delivery of a highly successful course on ionising radiation safety for
the Australian Defence Force (DIRPO). This course has been delivered at UNSW@ADFA since 1999.
I led the complete updating of the Physics Curriculum at UNSW@ADFA to provide a degree, enthusiastically
approved by the Australian Institute of Physics that is relevant to the officer cadets of the Australian
Defence Force.
Currently, I am leading the development of a postgraduate course in "CBRNE –
Fundamentals and Management" which deals with the foundation science and management of
incidents involving weapons of mass destruction (Chemical, Biological, Radiological, Nuclear
& Explosives). Details of this course can be accessed by going to

Research Activities
My research interests are in the field of high energy astrophysics, and scientific stratospheric
ballooning. I have co-authored over 110 research papers in international refereed journals and
refereed conference proceedings. I lead the High Energy Astrophysics Group in the School of
PEMS , UNSW@ADFA, where current activities include:
The development of instrumentation for hard X-ray astronomy, for use on space-borne and
stratospheric balloon payloads. We are studying the behaviour of proportional counters at very
high gas pressures, to produce instruments with high energy resolution and high sensitivity.
We have also developed a low background imaging X-ray device using scintillation counters.
The multi-wavelength study of selected neutron star and black-hole X-ray binaries in our
Galaxy. These studies are carried out using radio, millimeter, and optical telescopes in
Australian, Chile , India and Korea , and via spacecraft-borne and balloon-borne X-ray
telescopes.
I have participated in over 100 stratospheric balloon flights for scientific research from
sites in the UK , Zambia , Uganda , Maldive Islands and Australia . For many of these flights,
I have taken on various roles such as principle scientific investigator, launch director,
campaign manager, and station director. Since 1984, I have provided support to NASA for
their Southern Hemisphere scientific balloon campaigns in Australia . Such recent activities
include the development of super-pressure balloons for long duration flights lasting up to
three months.
