Hi Kelle! The videos from past PyData are online: https://www.youtube.com/user/PyDataTV but to be honest, as an astronomer, I have found the talks to be hugely interesting but often not as directly applicable to my own work (which is a function of what I work on, not a comment on the overwhelmingly positive level of quality of the talks). Your mileage may vary, but the ones I’ve been to usually have a strong focus on machine learning, streaming data analysis, applications of these things to industry processes, and so on. But, I’ve also seen some really rad talks about new tools, concepts around metadata harvesting and mining, and so on.
I think astropy might be of interest to present on, but it might also be well-received to present about how astropy formed, and the inter-organizational alliances it forged and so on, which are relevant to some industry groups.
It’s worth noting that each PyData conference is organized locally, so you might have luck reaching out to the local organizers, or checking what has happened at past PyData NYC meetings, to see what they tend to focus on.
Hope that helps, even if it’s a bit rambly!
