Huge congratulations to the most recent PhD in our lab, @jsrocchio.bsky.social, on his first-author paper in ACS Infectious Diseases! Joey built this beautiful toolkit for probing peptidoglycan biosynthesis and antibiotic action in A. baumannii cells. 🦠 #IUResearch tinyurl.com/46d8x9eb

Excited to co-chair the 2026 Gordon Research Seminar (GRS) on Thiol-Based Redox Regulation & Signaling with Taylor Covington, a meeting for early career researchers in redox research 📍 Castelldefels (Barcelona), Spain ☀️ 📅 July 11–12, 2026 #Redox #Thiols #EarlyCareerResearchers More details ↓

Excited to share our new preprint on self-S-sulfonation in persulfide dioxygenase CstB from S. aureus, unveiling how it detoxifies thiol persulfides via a dynamic loop shuttle to produce thiosulfate, no sulfite released! Crystal structures, MS, & mechanistic insights included. tinyurl.com/4sr3ayz5

Huge congratulations to grad student @katherinelegg.bsky.social on her new Science Advances paper, “CH•••S hydrogen bonds drive molecular recognition of ergothioneine by the microbial transporter”! 🎉 A beautiful collaboration of biochemistry, structural biology, NMR, and MD. tinyurl.com/3wxchjhp

Fantastic science this weekend at @iuqcb.bsky.social's Watanabe Symposium. Our grad student @jsrocchio.bsky.social even won the student poster competition! Thanks to @tripletstatesguy.bsky.social, @glycocode.bsky.social and all other speakers for great talks! #IUresearch

Our grad student @katherinelegg.bsky.social was a co-author on this recent publication in collaboration with the Reniere lab at UW! @gramnegativity.bsky.social was first author and has a great thread below going over the paper. Congrats Katherine, Lauren and all those involved!

Our lab has two talks coming up! 1️⃣ @emmcraechem.bsky.social is on a queer in academia panel at the OASIS conference tomorrow (Apr. 5th)! 2️⃣ @jsrocchio.bsky.social is giving a talk about a COG0523 protein in Ab at QCB evening on Apr. 17th! Both events require registration! See flyers for more details!

Don't miss Dr. Giedroc's talk on Tues., Apr. 9 at 9AM EDT on the Biometals webinar! It's an opportunity to learn more about grad student @mkosterb.bsky.social's work on metalloproteome integrity (with the Weerapana lab, Skaar lab and @chazinwalter.bsky.social). Register: shorturl.at/38yWM #biometals

📅 Save the date! 1️⃣ Fri, Apr 11: 1st Annual Undergrad. Chemical Biology Symposium Talks, poster session, facility tour, pizza, no registration! 2️⃣ Sat, Apr 12: 14th Annual Watanabe Symposium Talks, lunch, poster session, registration required!

Our lab is seeking a highly motivated postdoctoral research associate to study zinc metallochaperones from the COG0523 superfamily of small GTPases. Apply here: shorturl.at/UmQYM or send application materials to Prof. Giedroc directly at [email protected]. Looking for strong biochemists; please share!

Congratulations to our long-time collaborator Eric Skaar on receiving this prestigious Award in Molecular Biology from the National Academy of Sciences! www.nasonline.org/award/nas-aw...

@betainverse.bsky.social, our former research scientist, is now the Director of the METACyt Biomolecular NMR Laboratory! She'll oversee the training and operation of our state-of-the-art 600 MHz and newly installed 800 MHz Bruker Ascend instruments. Congratulations, Katie! 🧲 #NMR #IUResearch

Our review on bacterial metallostasis is now online in Chemical Reviews! This collaboration by the Giedroc (@betainverse.bsky.social and @jsrocchio.bsky.social) and Capdevila labs delves into bacterial metal regulation. 🦠 #Microbiology #ChemicalReviews #BacterialMetallostasis doi.org/10.1021/acs....

Drs. @betainverse.bsky.social and Diaz-Rodriguez purified EgtU, an ABC transporter that imports ergothioneine into bacterial cells, paving the way for structural and functional studies of uptake systems in S. pneumoniae and other pathogens. Kudos to the team! #BacterialTransporters shorturl.at/AUPTJ

Our very talented undergrad, Clare Frawley, presented her first poster today at the Indiana University Undergraduate Research Conference! 📊 🌟 Clare has been working with our grad student @jsrocchio.bsky.social on unnatural amino acid incorporation for live-cell cross linking studies! #IUResearch

🎉 Exciting milestone! Our paper on CiaR-controlled Ccn sRNAs modulating Zn-resistance in S. pneumoniae is out! Congrats to @iuqcb.bsky.social's @mkosterb.bsky.social and Dr. Abigail Garrett. This marks Prof Giedroc's 200th peer-reviewed paper!🔬🧬 #sRNAs #MetalHomeostasis shorturl.at/lMFM3

🎉 Our grad student @katherinelegg.bsky.social is a co-author on a new preprint about the genetic requirements and nutrient needs for Staphylococcus aureus growth in cystic fibrosis sputum. Congrats to @gramnegativity.bsky.social and all involved! shorturl.at/yfZQA 🧬 #CysticFibrosis #Microbiology

Dr. Giedroc contributed to "Trace Metals and Infectious Diseases," exploring metals' roles in microbial-host interactions. Edited by Eric Skaar and Jerome Nriagu, the volume shows metallobiology's significance for infectious disease research. 📚🔬 #Metallobiology #InfectiousDiseases shorturl.at/ua8kq

As the lab migrates over to #ChemSky, we are debuting our new lab logo designed by our own graduate student @jsrocchio.bsky.social. Happy to be here!
