This morning I had the privilege of participating in a graduation ceremony at the University of Sussex. It was great to get to shake the hands of all the successful graduates as they crossed the stage to receive their degrees. I hope I’ll be able to collect a few pictures of the occasion and post them in due course.
I also had the privilege of being able to present an extremely distinguished honorary graduand, Dr Chryssa Kouveliotou. Here the oration I delivered, which I’m posting simply to record her amazing achievements and to underline that she is one of many people who have done the MSc in Astronomy at Sussex University and gone on to do great things…
It is both a pleasure and an honour to present for the award of the degree of Doctor of Science, Dr Chryssa Kouveliotou.
Inspired by watching Neil Armstrong take his first step on the moon, Dr Kouveliotou always wanted to be an astronaut but, with no such opportunities apparently on offer in her native, she instead chose a career in astronomy. However, when she completed college Greece her astronomy professor (who shall remain nameless) advised her that there was no future for her in astrophysics. She has never known whether he really thought it was a poor choice or whether it was because she was a woman. Determined to follow her own path, she disregarded him completely and, even though her open-minded parents’ preference was for her to settle down and stay in her home country, she left to study for her Master’s degree in Astronomy at the University of Sussex; the topic of her dissertation was “The Sodium emission cloud around Io: mapping and correlation with Jupiter’s magnetic field”. She received the MSc in Astronomy in 1977. Although the topic of her subsequent research was rather different, the connection with magnetic fields remained strong.
Dr Kouveliotou then moved to Germany to do postgraduate research on the-then very new topic of gamma-ray bursts. Indeed, she may well have been the very first person to complete a thesis on this, which remains to this day an extremely active and exciting field of research. Gamma-ray bursts are considered to be the most powerful explosions in the universe, second only to the Big Bang itself.
After completing her PhD, Dr Kouveliotou returned to Greece to teach Physics and Astronomy at the University of Athens. All the while she knew that she really wanted to do research so spent her free time pursuing this goal. Every vacation and on her one-year sabbatical she went to the USA to undertake research at the National Aeronautics and Space Administration (NASA). Her work was on solar flares but she moonlighted during evenings, nights and weekends researching her ‘first love’ gamma-ray bursts. Because of the research she undertook outside her “day job”, she found a series of bursts which all came from the same part of the sky and, as a result, became part of the discovery team for a brand new phenomenon called a soft gamma-ray repeater.
By observing gamma rays produced in space, her team discovered an example of a new class of exotic astronomical object called a magnetar, an object which has a magnetic field trillions of times stronger than that of the Earth. A magnetar is now known to be a type of neutron star, a burnt-out relic resulting from the death of an ordinary star in a supernova explosion.
Dr Kouveliotou has always loved to ask big questions, to look at the universe and ask how nature expresses itself. By overcoming obstacles in her path she really has reached the stars. In January 2013 Dr Chryssa Kouveliotou was named the Senior Scientist for High Energy Astrophysics, Science and Research Office at NASA’s Marshall Space Flight Center in Hunstville, Alabama.
She has received many awards for her work, including the Dannie Heineman Prize for Astrophysics and the NASA Exceptional Service Medal in 2012 and the NASA Space Act Award in 2005. She was also named amongst Time Magazine’s 25 Most Influential People in Space in 2012. In 2003 she was honoured with the annual Rossi Prize by the High Energy Astrophysics division of the American Astronomical Society for a significant contribution to high-energy astrophysics. In 2002 she received the Descartes Prize which recognises scientific breakthroughs from European collaborative research in any scientific field. In the awards bestowed upon her she has also been recognised for her effectiveness at creating the sort of large collaboration needed to make effective use of multi-wavelength astronomical observations.
Dr Kouveliotou has published almost 400 papers in refereed scientific journals and has been amongst the top 10 most-cited space science researchers in the academic literature across the world. She has been elected chair of the Division of Astrophysics of the American Physical Society and is a member of the Council of the American Astronomical Society, of which she chairs the High Energy Astrophysics Division.
Vice-Chancellor, I present to you for the degree of Doctor of Science, honoris causa, Dr Chryssa Kouveliotou.
