14 Things Our PhD Supervisors Got Right and Why It Mattered

by Linda Nordling

When someone talks about doing a PhD, the stories that surface are usually about what went wrong: the overbearing adviser, the chaotic laboratory experiments, the loneliness and the stress. But the experience is rarely only that. Amid challenges such as funding uncertainty, competition for positions, pressure to publish and disruptions caused by global conflicts and crises, many supervisors quietly do things that change a student’s trajectory for the better.

Astronomers for Planet Earth: Gina Maffey

This feature is part of our ongoing series about the amazing women at Astronomers for Planet Earth (A4E), a global network of astronomers and astronomy enthusiasts dedicated to offering their unique perspective to the fight for climate justice. For this post, we'll hear from Dr. Gina Maffey, an interdisciplinary science communicator and founder of the Wildeor Foundation.

If you're interested in learning more about A4E's work combating global climate change and want to get involved, join them here at: https://astronomersforplanet.earth/join-us-1. And be sure to check out A4E's white paper on what astronomers (like you!) can do to address the climate crisis: Astronomers for Planet Earth: Engaging with the Public to Forge a Sustainable Future.

Dr. Gina Maffey is an experienced science communicator and interdisciplinary scientist with a guiding passion for the natural world. 

What is your current career and how did you end up there?

I currently sit as the chair of the Wildeor Foundation—a charity with the aim of Bringing Nature Back to Life. It’s been a very windy road getting here, but the path has never veered too far from environmental topics. Academically, I started in the UK with a BSc in Zoology, Masters in Ecology and Environmental Sustainability and a PhD in Environmental Science. However, during this time I also built up a portfolio of experience in science communication, including a British Science Association Media Fellowship. I began to wonder whether moving to another discipline would offer an opportunity to really understand and improve my science communication skill set. After working in South America for two years in environmental communication I accepted a part-time post in the Netherlands at the Joint Institute for VLBI ERIC (JIVE)—a European Radio Astronomy Institute—where I was introduced to a whole new universe of concepts, ideas and terminology. Throughout my time at JIVE I maintained a strong connection with the natural world, also working with conservation and outdoor skills organizations - and even spending a year living outside in some of the wonderful natural areas that the Netherlands has to offer. I was inspired by many of the conversations that I had with the astronomy community and a small group of us came together to establish the Wildeor Foundation, where we are keen to explore cross-disciplinary approaches to nature connection in everyday life.

What is your role in Astronomers for Planet Earth (A4E)?
I am one of the co-founders of the European arm of A4E. This began in 2019 at the European Astronomical Society conference in Lyon—what started as a conversation with one astronomer on climate change quickly snowballed into our first official meeting by the end of the week. As we were establishing ourselves we came across the newly formed Astronomers for Planet Earth in the US; at this point, we met online and joined forces to form an international group—after all, there is only one planet we are fighting for! I continue to be actively involved in many different aspects of A4E, and currently this is focused on much of the background framework to ensure the long term sustainability of the movement.

What goals do you have for your role in A4E?
I really want to work towards astronomers having a key voice in the environmental movement. I continue to be inspired by the dedication and depth that astronomers engage with the climate crisis, you (astronomers) speak the language of data and you can see that data as part of a much greater and complex picture. The climate crisis may be our global society’s most pressing problem, but it sits alongside a plethora of environmental issues that require as many voices as possible to collectively shout that something needs to be done, now.

Dr. Maffey observes the delicate beauty of an elephant hawk moth.

Describe the first time you made a personal connection between your passion for astronomy and the urgency of fighting climate change.
For me, this sits the other way round. My passion for environmental issues has never waned, and engaging with the astronomy sector has only stimulated me further. To pin an actual moment in time is difficult, but the greatest catalyst was undoubtedly meeting the wonderful group of people at the 2019 European Astronomical Society in Lyon. Many of these individuals have become friends through the A4E movement and that social interaction in turn serves as an incredible motivator.

How does your career in astronomy intersect with the fight against climate change?
It has steered my career in ways that I could never have anticipated. I have been lucky enough to present and write about astronomy and climate change, which forces me to review and reflect on my own thinking and I am continually challenged by the discussions that occur through A4E. Above all though, it is influencing how the Wildeor Foundation is growing. It is now less an intersection and more a parallel, conjoined path.

How can the astronomical community engage with the climate crisis movement?
By understanding how environmental change will affect the conduct of astronomy. It is somewhat misleading to think of environmental topics under a disciplinary label. The environment should form the foundation of each action and decision that we take— what will the long term impact be? What is the true economic cost? Who will be affected by the decisions that we make now? Asking these kinds of questions embeds astronomy in both (local and global) social and environmental frameworks. It also demonstrates that there is a lot of room for change, and that, at the very least, astronomers have the power to make those changes in their own field.

If you weren’t in the field of astronomy, what would you be doing?
Investment banking.

No, I jest. I still think of myself as an outsider in astronomy, just as I do in ecology, environmental science and science communication. For me, the labels mean little, but my interest for nature runs deep. I know that wherever I was, even in investment banking, I would be fighting on behalf of the natural world.

Do you have any advice for future astronomers who might also be interested in addressing the climate crisis?
Join Astronomers for Planet Earth.
Start asking questions and challenge the status quo.
Finally, don’t be intimidated, there is an overwhelming amount of data on climate change, there are climate scientists, climate communicators, climate policy officers… the list goes on. It is impossible to read and know everything, the unifying factor is that those in the field trust what the data is telling them and understand that change has to happen now. The best thing you can do is support them and amplify their message.

Tips from Nature 'Women in STEM' Articles

This week's guest blogger is Johanna Teske, who is finishing her fifth year as an Astronomy graduate student at the University of Arizona, Steward Observatory (applying for jobs this fall, hint hint!). Johanna investigates the chemical connection between stars and planets and also dabbles in education research.

As many of you know, and at least one other recent post here has highlighted, the 7 March 2013 issue of Nature contributed to the theme of Women's History Month, "Celebrating Women in Science, Technology, Engineering and Mathematics" with a series of articles describing the current status of women in STEM across the globe, what progress has been made towards equality, and the disparity and injustices that still exist for women in science. In this blog post, I focus on the possible solutions that the Nature articles discuss; this is not meant to be a summary! Some (most) of these solutions seem obvious, but I interpret their continued appearance in articles/discussions as an indication that they have yet to penetrate the consciousness of most people…or at least those making big decisions. I cannot encourage you enough to read all of the articles themselves -- none are very long, and all are jam-packed with much more information than what I highlight. The link to the articles is here. As you read the articles, and this post, think critically about how you and your colleagues, organization, and institution can work toward implementing some of these goals and making STEM fields a friendly, motivating, and exciting environment for everyone. Also, please share your efforts in the comments or as a separate blog post – it’s important to both set good examples and evaluate each other’s best-practices for potential improvements.
