At CREST, we aim to showcase the diverse career trajectories and perspectives of researchers who have navigated the path beyond their PhD. The “Beyond the PhD” series provides an opportunity to hear directly from experts across different fields about their experiences, challenges, and insights on life as a researcher.
For this third installment, we are featuring four distinguished researchers: Benoit Schmutz (Ecole polytechnique, IP Paris), Caroline Hillairet (GENES, ENSAE Paris, IP Paris), Paola Tubaro (CNRS, ENSAE Paris, IP Paris), and Nicolas Chopin (GENES, ENSAE Paris, IP Paris). Each of them shares their thoughts on the PhD journey, its impact on their careers, and the broader role of research in society.
Why pursue a PhD at CREST?
A PhD is much more than just academic training—it’s about developing a mindset that allows you to explore complex questions, think critically, and push the boundaries of knowledge. Our researchers highlight three key aspects that define the PhD experience at CREST:
🔹 An Environment for Intellectual Growth – A PhD is a journey of constant learning. You will develop a structured way of thinking, gain expertise in your field, and learn how to navigate uncertainty in research.
🔹 Opportunities for Interdisciplinary Work – At CREST, you will interact with researchers across economics, sociology, finance, and statistics, allowing for a dynamic and stimulating research experience.
🔹 A Supportive and Collaborative Research Culture – While research can be challenging, you will not be alone. Engaging with peers, supervisors, and the broader academic community is essential, and at CREST, we value collaboration as much as independence.
