We come back to the question of S2E05: you have studied mathematics... now what? We met our old friend (and former co-host) Marit van Straaten and our former student Josselin Kooij, to talk about the possibilities for mathematicians that don't pursue a career in academia.

After getting to know them, with their motivations to study math and their hobbies (mainly sports!), we focus on their careers. Their different seniority levels allow us to span across many topics, with both a fresh and an experienced eye, in an episode that we hope will clarify many of your doubts on what to do to look for a job as mathematicians, and plenty of useful tips for when you interview for a position!

We plan to do a few more of these, so if there is anything that you would like to discuss in the next episodes, let us know in the comments (or sending us a message).

In this special episode, we return to the topics of learning and teaching mathematics. We are joined by Brendan Kelly, Director of Introductory Mathematics at Harvard University, to discuss the opportunities that active learning has to offer.

Throughout the discussion, we get to know Brendan, exploring his journey into mathematics and what led him to focus on education. Both lecturers and students will find many useful tips and tricks scattered through the recording, and we are sure you will feel Brendan's infectious energy and passion for both subjects!

This is the first episode of another small spinoff of It's Not Just Numbers, were we discuss with researchers working on mathematical topics in different disciplines and departments.

In this episode, we talk to Jorge Perez (Computer Science department) and Davide Grossi (Artificial Intelligence department). As you will hear, both of them use a lot of mathematics in their research and work on topics that also have very theoretical angles.

Throughout the episode, we discuss intedisciplinary collaborations, reaching outside one’s own line of research and the key role ofof asking questions to facilitate the exchange. We also explore if and how common stereotypes on academics change in Computer Science and Artificial Intelligence from a societal point of view.

What is a proof? And what is a proof assistant? Isn't writing proofs what mathematicians are supposed to do themselves? In this episode, Sander Dahmen and Jim Portegies, will help us explore these questions and introduce us to the fascinating world of fomralizing mathematics. Of course, after taking our time to get to know them better.

You have studied mathematics... now what? In this episode we talk to Sven Bootsma, Max Lein and Oscar Koster about the possibilities for mathematicians that don't pursue a career in academia.

After getting to know them, with their motivations to study math and their hobbies (mainly sports!), we focus on theie career in industry after having studied mathematics . In this long episode we span across many themes and discuss how a mathematician can find a job in industry, what the differences are with working in academia and how students could go about choosing a career after their studies.

This episode is packed with insights and interesting suggestions but only scratches the surface of this interesting discussion, leaving many additional question unanswered waiting for a future afterMath2 episode!

So let us invite you to join us in a future recording: if you are a mathematician and you are not working as an academic, especially if your job is different from the ones that we heard about in this episode, please send us a mail!

And if there is anything that you would like to discuss in the next episodes, let us know in the comments (or sending us a message).

What does it mean to do research? What does a researcher in mathematics do, effectively, to research? In this episode, we pick up a common question from our listeners, and try to give some partial answer with the help of Pinar Kilicer and Hildeberto Jardón Kojakhmetov. After taking the chance to know them better, we look back at their career and what were the most important moments to grow into research, putting this all in the perspective of the students thanks to the help of Anna.

In this episode we are joined by Ekin Özman and Bart Besselink to discuss what are the work days of a mathematician at a univerisity like. With their help we get a little panoramic on what a career in mathematics looks like and what are the expectations, the priorities and sometimes the compromises that it requires.

As usual, the episode touches upon a great variety of topics, don't miss it!
