Name: Marie Arnika Gärtner
Graduation Year: 2024
Country of Origin: Germany
Institution: University
What are your daily tasks in your current position?
I am currently pursuing a PhD in geophysics, specifically in volcanic seismology, at ISTerre in Grenoble, France. I work with seismic data recorded near active volcanoes. Since the data is already available, the majority of my work takes place at the computer. I process and analyze seismic signals to better understand how their characteristics relate to physical processes inside a volcano. By using these signals as a window into the volcano and its internal system, my research aims to uncover the underlying physical mechanisms. Linking these processes with the recorded signals ultimately contributes to improving the monitoring of volcanic activity.
Which scientific qualifications and soft skills from your studies help you the most in your job?
The research-oriented Master's program at the Geophysical Institute (GPI) of KIT was the perfect preparation for starting a PhD. Working on my Master's thesis for an entire year gave me a realistic insight into research life. One of the most valuable aspects of my studies was the close collaboration within a small team. Regular presentations and discussions helped me learn how to give and receive constructive feedback. I really valued the supportive environment at the GPI. Overall, the transition from Master's studies to the PhD felt very natural, just with more autonomy and responsibility.
What excites you most about your job—and what is the most exciting challenge?
What I like most about my job is the constant challenge. I am curious, and in research, there is always something new to learn or discover. At the same time, this is also the greatest challenge. Research requires a lot of self-motivation. Sometimes you invest a lot of time and effort without seeing immediate results, which can be frustrating. But that is part of the process: even if something doesn't work out, you still learn from it.
How did you get your current job?
I found my PhD position through networking and open conversations. I talked to many people about their experiences during their doctoral studies, about what was important to them—for example, when choosing a supervisor and their topic—and what they would do differently. During one of these conversations, I spoke with a former supervisor of my Master's thesis who had recently completed his PhD. He put me in contact with my current supervisor. I then had the opportunity to be a guest at ISTerre for two weeks, to discuss my potential research topic, and to get to know the institute. At the end of that visit, I was offered my PhD position.
What was your personal highlight during your studies at KIT?
For me, my time at the GPI felt like being part of a small family. I look back on it with great fondness and am always happy to visit. Because we worked in a small team, everyone knew each other and supported one another. I had the opportunity to present my research results at small conferences at an early stage, which—as I realize today—is not very common. I was also encouraged to turn my Master's thesis into a scientific publication. Even after I started at ISTerre, I continued to receive support for this. Such an environment, where you can easily get in touch with everyone and feel supported, was a great source of motivation for me.
What advice would you give to geophysics students or pupils for their professional future from today's perspective?
My most important advice is: Talk to others. By talking to people about their work, you gain insights into career paths you might not have considered before. It also helps you to better understand what you are actually looking for. At the same time, do not hesitate to share your own interests and goals. This allows others to connect you with ideas, projects, or positions you might not have found on your own. In short: Stay curious, be open, and don't be afraid to reach out.
