It was such a pleasure to co-chair the workshop "Data Analysis: Collection, Preparation and Visualization" with Sue Pearring at #SOFT2025 in Portland. I think everyone on stage learned from the other speakers, so hopefully attendees got something out of it as well! 😆 (1/3)

[Brigitte Desharnais @ToxBrigitte]

Thank you so much to the other contributors to this workshop Tyler Devincenzi, Aria McCall and Kevin Davidson. (2/3)

Back home from #SOFT2025 Workshops! 🛬 I covered the changes to qualitative methods validation in the workshop "Validation: Navigating the Latest ANSI/ASB 036 Revisions". This is a challenging topic! 😅 (1/2)

[Brigitte Desharnais @ToxBrigitte]

The Canadian Society of Forensic Science Annual Conference kicked off this morning with workshops! #2025CSFS 😄 It was a great pleasure to share perspectives on evaluative reporting in forensic toxicology - albeit from a few hundred km away. (1/2)

[Brigitte Desharnais @ToxBrigitte]

📝 This is the first part of a deep dive on the statistics of qualitative methods, and how they can be validated properly.

My most recent paper now in the lastest #TIAFT Bulletin issue:
➡️ You thought qualitative methods were DUMB, but their complexity will SHOCK you
(1/3)

[Brigitte Desharnais @ToxBrigitte]

🛜 (Seeing as the TIAFT Bulletin is now available online only, I thought it my duty to provide the Editors with some click bait material so it can have the same success via social media than it did on paper!)

@FredFred1406 @ChantalHbert @bruceanderson To be fair I'm pretty sure Trudeau did not think in French when speaking, and he's francophone 😅 Not sure this should be the standard.

[Brigitte Desharnais @ToxBrigitte]

I typically stay away from politics here, this being a mostly profesionnal account. But this summarizes all my feelings. I want to be involved in this election. I want @MarkJCarney to be our Prime Minister. I want a true, pragmatic, intelligent, knowledgeable leader. #Carney

[Brigitte Desharnais @ToxBrigitte]

Good one 😆

And this #TIAFT Bulletin issue has yet another Statistics Series Chapter - on descriptive statistics! 📊 What should have been an early chapter in the series actually ends up published ninth - better late than never. 🕓

Using qualitative (positive/negative, above/below threshold) methods?
Join the upcoming #SOFT webinar on the topic!
I will be discussing the consequential upcoming changes to the ASB 036. Validating qualitative methods will look quite different when this 2nd Edition is out!
