2025 update because I'm not seeking to hire anyone or sponsor any new students right now. Possible exceptions for people who are *really* allied with my funded work (e.g., on mpox vax, vax misinfo) and/or have access to external funding (e.g., fellowship, home nation). Lab is at capacity for now.

Prospective students: Here's what you need to know if you think you might want to work with me (a thread):

1. I'm not looking to recruit new students at the moment. (There could be some exceptions, especially for research-oriented Master's students in my school or interdisciplinary studies.)

X rolled out a new feature that accidentally exposed a massive covert foreign influence operation — more than one, actually — that is currently live on the platform. It’s a huge story and I wrote about it — and what it means for America — here:

Lots to like in this #pharmacare report (it's feisty!) tho I still worry its approach to WHO #EssentialMedicines lets fall through the cracks the many drugs on the WHO EML💊📜, from #albendazole to #tuberculosis drugs, that aren't actually sold in Canada despite being the recognized standard of care.

Keep this in mind when people claim cars mean business — closing Central #Madrid to cars over holidays resulted in a 9.5% boost in retail spending on its main shopping street: STUDY.

There was also a 71% drop in air pollution.

(Or even if not quite =, good enough that the loss in learning is outweighed by the greater # served. For ex, it’s only 60% as good but we can teach 3x as many so it’s a net gain in terms of instructor time. A very quant way to think about it, but larger classes are driven by economic pressures.)

Yes, are you aware of anyone using online interactive modules successfully for graduate level qualitative methods training? (Maybe Master’s level, since it seems unlikely at PhD level.) I’d love to hear from instructors who feel they’ve been able to give equivalent instruction in large groups.

Heading to Montréal for CBRC Summit! If you are too, I’d love to connect about queering pandemic preparedness, gender health misinformation, public health surveillance ethics, and related topics.

#QualitativeHealthResearch #QualitativeMethods
Talk to me abt course size for grad level qualitative methods.

I have always believed small is important for these courses. But, am I out of date?

Are people offering semester-long, effective, graduate-level quali methods courses w 50-100 students?

Oof, that’s so rough.

I had one in the midwestern USA where everything/everywhere was sooooo fragranced. Including/worst of all the personal vehicle someone was driving me from place to place in. My allergic self was…not at my best. 😵‍💫

#Canada #MediaStudies folks: Was there ever any sort of assessment of the impact of the famed Canadian House Hippo? (Thinking about the original, but the 2019 redux and associated campaigns also interesting.) I see wide cultural impact, but the intended media literacy impacts...?

My social media is wall-to-wall love for the incomparable Alice Wong, and I need more words. What captures sadness and/also affection for a community that knows what's been lost?

Alice could not eat food for years.

And yet at Christmas she would bake cookies and mail them to me—such was her desire to provide care for the people she loved.
