In this episode I speak to Prof Juan J. Alonso on his vision of the future of computational science as well as his journey from academia to entrepreneurship - founding Luminary Cloud. He reflects on the revolutions in computational science and the different ways of developing software throughout his career. Alonso emphasizes the importance of academia in creating and perpetuating knowledge, as well as the value of innovation and new ideas. He also discusses the changes in the CFD world, the emergence of new technologies like GPU computing and cloud computing, and the potential for advancements in computational simulations for analysis and design. We also touch on the transition of the aerospace industry towards commercial software and the potential for cloud computing to revolutionize CFD. The conversation concludes with a discussion on the progress made towards achieving the goals outlined in the 2030 CFD vision report and the role of machine learning and AI in simulation-driven workflows.

In this final part of the conversation, Juan discusses the potential applications of ML and AI in engineering. He identifies four main areas where these technologies can be beneficial, but emphasizes that these applications will always be based on high-fidelity simulations. He concludes by envisioning the future of computational-driven science and the continued innovation in the field.

In this conversation, Neil interviews Dimitris Katsanis, one of the world leading experts in bike design. They discuss the UCI regulations that govern bike design for road and track racing. Dimitris explains the evolution of bike design and the role of carbon fiber and titanium in creating lightweight and aerodynamic bikes. He also talks about his collaboration with Pinarello and the development of the Dogma F8 and F10 bikes.

Dimitris emphasizes the importance of balancing weight, stiffness, and aerodynamics in bike design and the ongoing pursuit of improvement in the field. In this part of the conversation, Dimitris Katsanis discusses the evolution of bike design, the importance of aerodynamics and system drag reduction, the differences between track and road bike design, the interactions between the bike and rider, the impact of weight and aerodynamics in solo breakaways, the ongoing weight vs. aero debate, the role of stiffness in bike design, the relationship between stiffness and comfort in bike frames, and the potential of 3D printing and additive manufacturing in bike manufacturing.

In this conversation, we also discuss the limitations of carbon fiber in bike design and the potential of 3D printing to overcome these limitations. He explains how 3D printing allows for the creation of custom shapes and internal structures that can improve the performance and weight of bike components. Katsanis shares examples of 3D printed handlebars and frames that are lighter than their carbon fiber counterparts. He also discusses the future of mass customization in bike design and the impact of regulations on innovation.

Finally, he speculates on what bikes may look like in the future if design restrictions were lifted.

Summary

In this episode, Neil discusses four key career questions that you should think about. He explores the pros and cons of pursuing a PhD, the path to becoming a professor, and the opportunities in the tech sector. He highlights the importance of gaining industry experience and the potential for higher salaries in the tech sector. Neil also mentions the option of dual positions, where academics work in both academia and industry. Overall, he encourages listeners to consider all the options and make informed decisions about their careers.

Takeaways

Doing a PhD can provide expertise and specialization in a specific area, but it may delay entry into the job market and result in lower initial salaries.
Becoming a professor requires a PhD and often involves postdoctoral research positions. Advancement to higher ranks, such as associate professor and full professor, requires publishing, securing funding, and taking on leadership roles.
The tech sector offers high-paying jobs and opportunities for engineers, particularly in areas like machine learning and data science. Tech companies value both academic and industry experience.
Consider the trade-offs between academia and industry, such as job security, work-life balance, and the level of freedom and autonomy.
Dual positions, where academics work in both academia and industry, are becoming more common and offer the best of both worlds.
