@Palani_IISc @iiscbangalore Congratulations!!!

[Vignesh Palani @Palani_IISc]

Hello everyone, I have officially joined twitter and wanted my first post to be a special one! On that note, I am excited to share that I'll be joining the Department of Organic Chemistry @iiscbangalore as an Assistant Professor starting this week!

Excited to see part of my work from when I was an @Amgen Scholar at @UCBerkeley published! Nature and chemists continue to impress me with their synthetic prowess, especially when their strategies converge!

The synthesis features a number of unusual maneuvers, all confirmed by X-ray crystallography.

@JJWatt You were the best boyfriend I never had ❤️

[Karl Haelsig @KHaelsig]

@mevans86 My issue is with the yields! Check the equivalents for each class of substrate!

@ClaireMagnani @femipv @Momademia He’s already a grad student

@GavinNewsom Nice virtue signal. What are you doing to ameliorate the current UC graduate student strike?

[Stephanie deGiorgio @DrSdeG]

What is this shitty not-flu, not-covid, not-RSV thing going around??

It has taken out my team at work one by one and both kids poorly now. I had it two weeks ago. Felt bloody awful.
Making people get tracheitis, febrile, sore throat.

Any virologists know? Paraflu?
