    34. Challenges of an academic career path – a conversation on productivity, creativity, and funding

    How important is it to be productive to succeed in academia? And what about being creative? In this episode, we once again have the pleasure talking to Prof. Fredrik Höök, Professor of Nano and Biophysics, at the Department of Physics at Chalmers University of technology. Prof. Hook was our guest in episode 29. Then we had an interesting conversation around several aspects related to research and life in science. At the end of the session, there were still lots of questions that I was curious to ask, and fortunately, Prof. Hook kindly agreed to continue the discussion in an additional episode. This time, we talk about some of the challenges of an academic career path and how to strategically relate to these.  We pick up the conversation essentially where we left it - Prof. Hook had just mentioned that he decided to go for a career in science despite all the risks and uncertainties involved. We talk about what those uncertainties are, and how they can be addressed and related to. We also discuss the potential need for a backup plan, the role productivity, inspiration, and if it is important to be creative to succeed with an academic career. Prof. Hook shares his best advice to those of you that dream about pursuing a career in science but who hesitate, or think it seems too risky. He also shares his view on what personal qualities that are needed to be successful in academia.  Thanks for listening!

    33. Modelling and Mathematical Models in Science

    What is an initial value problem? And why do many of us find mathematical modelling so challenging?  In this episode, we again have the honor of talking to Prof. Marina Axelson-Fisk, Professor in Mathematical Statistics at Chalmers University of Technology.  This is the third time Prof. Axelson-Fisk is a guest in Science on Surfaces – tips, tricks and tools, and this time she shares some of her vast knowledge on mathematical modelling and how this is used in science.  As always, we started with the basics and Prof. Axelson-Fisk explained what mathematical modelling is, when it is typically used, and what is important to consider when doing this type of analysis. Prof. Axelson-Fisk also described a few examples of common models and their characteristics, how to improve a model and how to find the set of parameter values that best fit the data. We also talked about assumptions, limitations, and validation, as well as challenges encountered when modelling, and pitfalls to avoid. She also shared her thoughts are on why so many of us find modelling so challenging and how this limiting barrier can be addressed. This episode really is packed with information.

    31. Data analysis basics and how to make the most of the collected data

    Data analysis basics and how to make the most of the collected data How do you maximize the information extraction from that data that you may have spent weeks collecting? And what is the difference between ‘precision’ and ‘accuracy’? In this episode, we talk to Prof. Marina Axelson-Fisk, Professor in Mathematical Statistics at Chalmers University of Technology about Data analysis, to learn more about how to make the most of the data that you have collected. In this informative conversation, Prof. Axelson-Fisk guides us through a range of different data analysis types such as exploratory-, descriptive-, and predictive analysis and explains when to use which method. We also talk about the data analysis process from start to end; how to handle the data before you analyze it, requirements on the data input, and how to assess the analysis output. We then move on to briefly discuss data modelling and key aspect related to this procedure. Prof Axelson-Fisk’s explains key terminology such as repeatability, replicability and reproducibility. And, finally and once and for all, we get the difference between precision and accuracy explained. Last but not least, we talk about the main challenges with data analysis, what pitfalls to look out for, and we get a recommendation on data analysis software to use.   By the way, the English translation of ‘supraledare’ is of course ‘superconductor’ Thanks for listening!
