Congratulations @ChabaRachna on this comprehensive study 🥳. Grateful for your support through it all. We thoroughly enjoyed it. Humbled by the recognition. 😄

Excited to share Deeptodeep’s PhD work https://t.co/QX3uNc6F5o Congrats on first & co-corr. authorship! We uncover redox switch as a novel mode of activation of E. coli envelope protease DegP that enables it to integrate various stress cues @caughtnd_act @DBS_IISERM @IiserMohali

✅✅ A reminder by Dr. Rahaf Ajaj:

She wasn’t on the Stanford list… but she made it to the Nobel stage. 🏅

Mary E. Brunkow, one of this year’s Nobel Prize winners in Medicine, has only 34 published papers and an H-index of 21.

She never appeared in Stanford’s ranking of the world’s top 2% of scientists.
She didn’t chase citations, metrics, or the spotlight.

Yet, she became part of a discovery that changed how humanity understands the immune system.

Today, while many are busy chasing numbers, titles, and rankings —
she reminds us what truly matters in science: the question.

🔹 She wasn’t running after the lists.
🔹 She was running after the truth.

Because in the end, it’s not about how many papers you publish…
It’s about how deeply your idea can reshape the world.

Focus on your idea, not your ranking.

Excited to share our new publication, out today in Nature! https://t.co/YQhq53nAhB
I am grateful for our wonderful collaborators and the lab. We show that a common gut fungus enhances Salmonella infection by driving arginine release, uncovering a new cross-kingdom mechanism.

What a great story from @laurenpalmerphd group. So happy to be a part of this amazing work.

[Rachna Chaba @ChabaRachna]

Thank you @India_Alliance for the opportunity to share work from our group. It was a great meeting- excellent science and wonderful community! @IiserMohali @DBS_IISERM

[Gaurav Sharma, Ph.D. @sharmaG30]

It was a pleasure to host @ChabaRachna at @BTIITH, two years after our Ist collaboration chat on @X! Her talk on sugar acid metabolism in enteric bacteria was a hit. My lab folks also pitched their projects for her feedback.

Super excited about the ongoing collaborative ideas!!

[Deeptodeep Roy, PhD @RoyDeeptodeep]

Cheers to the team 😁

[Rachna Chaba @ChabaRachna]

1/2 Elated to share our work in @JBacteriology @ASMicrobiology Using genetics, biochemical, bioinformatics & simulation studies, we investigated functional consequences of variations in a GntR/FadR family regulator of sugar acid metabolism in E. coli
