Foreword Welcome to the "Congrès des Doctorant·e·s", the annual meeting organized for and by the PhD students of the STEP’UP Doctoral School.

As you all know, due to the health situation, the congress could unfortunately not take place in 2020 as well as in 2021 in its usual form. But the motivation and initiative of our PhD students has finally taken over. The direction of the STEP’UP doctoral school would like to thank and congratulate the PhD students who have organized this meeting despite a highly unstable context. This year, the congress format changes - one day, outside, around scientific posters - but its main objectives remain: this is first of all a great opportunity to meet you all and discover the scientific subjects addressed in the various laboratories of the doctoral school. In this complicated period for many of us, meeting and exchanging with your colleagues and friends, including new first year PhD students, is particularly important. We hope you will enjoy the Congrès des Doctorant·e·s Déconfiné·e·s day and will renew scientific and friendly links between you all.

As usual, this meeting will not only express the thematic diversity of our doctoral school, it will also provide great opportunity and broad scope for the exchange of ideas and for interdisciplinary collaboration. In addition, it will be a unique opportunity for doctoral students to share their science with their colleagues and place their activity at the center of a community of scientists from Université de Paris, Sorbonne Université, Paris Sciences et Lettres and the Institut de physique du globe de Paris.

This day is the time to celebrate research and innovation in a myriad of fields including geology, geophysics, (bio-)geochemistry, geomagnetism, volcanology, tectonics, geodynamics, astrophysics, cosmology, particle physics and planetary sciences. All of the poster presentations will be a new source of inspiration for your future studies and allow you to learn from colleagues, develop strategies and gain visibility in your growing scientific network. By exchanging with your peers, you will develop new skills and participate in the construction of projects that will enable you to better contribute to the sustainable development of terrestrial and planetary environments.

This is your meeting, make it great and enjoy this day of scientific exchanges.

Sanitary rules This is an unusual edition of the Congrès Des Doctorant·e·s, in unusual times. To guarantee the safety of all attendants, CD3 organisers, IPGP and STEP’UP administrators kindly ask you to respect the following guidelines:

• DO NOT attend CD3 if you are experiencing COVID-19 symptoms or have been identified as a “cas contact”.

• Wear a category-1 face mask at all times when interacting around posters.

• Eating and drinking is only allowed in IPGP’s courtyard. Food and drinks will be served on dedicated booths by the organizers.

• Hydro-alcoholic gel will be available in several places

around the posters, use it!

• Avoid bringing your own food or drinks to share with friends.

• Keep enough distance (1m) with poster presenters and

avoid large gatherings around poster: wait for your turn to hear about this awesome science!

The “Better Poster” This year, we would like to present you an original poster format: the #betterposter. Whether CD3 is your first ever poster session, or you are already an experienced poster maker, you might have noticed that poster-making is a time-consuming task, and that having to compress months, even years of research onto a A0 rectangle is not always easy nor rewarding. The Better Poster’s intention is to minimize the time you spend on making your poster, while maximizing the conversation quality and information exchange between you and other conference attendants. The idea is to use a simple, yet efficient poster design focusing on your key results. To find out more, type “How to create a better research poster in less time” on YouTube, and look for Mike Morrison’s essay!

A few words on Hekla

About the association

Hekla is an association gathering PhD students from the Institut de Physique du Globe de Paris, but also more broadly students from the STEP'UP doctoral school as a whole. Its objective is to promote exchanges between all of us students. Whether you are a doctoral student, foreign or not, Master or Licence student, researcher or member of the administrative staff, the important thing is to be able to meet and interact in a more informal setting. In this sense, Hekla offers festive, cultural and sporting events such as international cooking competitions, it organizes the graduation party, Christmas party and more! These events, small and large, give us a healthy and friendly workspace, as PhD, Licence and Master students in the various laboratories attached to the Doctoral School.

Therefore, after long months without any event due to the Covid-19 sanitary crisis, we, the Hekla team, are very enthusiastic to resume our activity by helping with the organization of the Congrès Des Doctorant·e·s Déconfiné·e·s (also known as CD3).

A renewal of the Hekla team leader by new PhD is carried out each year. If our

goals resonate with you, if you have new ideas to federate all students in the ED and beyond, come and join us!

To keep up-to-date with Hekla’s last events, follow the Facebook page @HeklaIPGP. Feel free to contact us via email for further information or if you have any questions: hekla-admin@ipgp.fr.

Impatient to meet you !

The Hekla Team
