The ACS Div. of Analytical Chem. Education Committee launched a "Meet an Analytical Chemist" initiative this spring to highlight members of our community. Our newest entry showcases @shirajoudan.bsky.social, an Asst. Prof. of Chemistry at @ualberta.bsky.social. Check it out here: shorturl.at/7VFIR

Meet an Analytical Chemist – May 2025

Shira Joudan, Assistant ProfessorDepartment of Chemistry, University of Alberta How did you get started in the field of Analytical Chemistry?  In undergrad, I took introductory analytical chemistry…

There have been arguments to redefine #PFAS that seem to be politically or economically motivated. We (20 scientists with PFAS expertise) argue here that the definition of PFAS should be unambiguous and based on chemical structure. pubs.acs.org/doi/10.1021/...

Forever chemicals: Scientists condemn massive lobbying campaign to alter PFAS definition

Forever chemicals: Scientists condemn massive lobbying campaign to alter PFAS definition

In a letter published Tuesday in a scientific journal, a group of 20 researchers warn that 'this effort is politically and/or economically, rather than scientifically, motivated.'

In this issue of Nature Chemistry, I write about the importance of having an online presence that we control ourselves. Since you're all on Bluesky, you're probably already on top of things! Open access sharing link: www.nature.com/articles/doi...

Controlling our online professional persona

Nature Chemistry - Modern scientists exist within the digital world. Shira Joudan describes how an online presence is beneficial to researchers, and what a baseline presence can look like.

@shirajoudan.bsky.social of @ualberta.bsky.social is interested in how contaminants get where they are and how we can understand chemical reactions to better understand their fate. Read more: cen.acs.org/environment/... #CENT12 #chemsky 🧪

They’re here! Introducing the Talented 12 Class for 2025. These early-career scientists are taking on big global #chemistry challenges. Meet the 2025 Class: cen.acs.org/people/profi... #CENT12 #chemsky🧪

I'm excited and honoured to be recognized as a C&EN Talented 12! cen.acs.org/environment/... Check out the other fantastic recipients here: cen.acs.org/people/profi... #chemsky

I have an open postdoc position in my environmental chemistry group at UW-Madison (starting summer or fall). Project focuses on applying high-resolution mass spectrometry to complex mixtures, including PFAS and dissolved organic matter. Email me directly if interested. Application deadline: May 15

Excited to be running another Schlenk line webinar tomorrow with @vacuubrand.bsky.social! There's still time to register using the link below 👇 www.vacuubrand.com/news/webinar...

the best screen to see (and not just because it means I have a new paper coming soon 👀)

wild being in Edmonton, where the sun still doesn’t set for another 40 minutes, and we already know Carney won. still lots of time to watch the specific races in each riding

Hey #chemsky and #science Bleeps (?)...the Chemscrapes project page has been updated to include a free download of a massive poster size parafilm PSA poster for your lab www.chemscrapes.net/s-projects-s... While you're there, check out other ChemScrapes projects. Shares appreciated :)

Thanks to Tamzin for leading this important conversation -- check it out here: pubs.acs.org/doi/10.1021/...

so excited about this!!! let's goooo

A Thesis on the process of publishing a research paper, from writing the intial draft to receiving the acceptance email from the journal, by Shira Joudan @shirajoudan.bsky.social www.nature.com/articles/s41... #chemsky

Preparing and publishing a paper - Nature Chemistry

There are many steps to preparing a research article for publication, from generating the figures and writing the draft, to responding to reviewers. Shira Joudan explains how their group approaches this task, specifically during the preparation of the research group’s first paper.
