I am so honored to have been selected as a shortlisted finalist in neuroscience for the 2026 Takeda Innovators in Science Award with @NaturePortfolio!
I’m excited to participate in Nature’s career development programs, while building meaningful connections with my peer awardees (including my good friend and colleague, Ai Ing Lim @Princeton!).

If you want to build such modern reagents and like doing a bit of organic chemistry and some biology, do consider joining my lab (DyeCraftLab.com) at National Centre for Biological Sciences (NCBS) Paper link: lnkd.in/enGd7Q5M

Our collaborative paper is online! We built two types of genetically targetable live-cell permeable fluorescent reagents: biotin for organelle purification, and JQ1 for chromatin manipulation! We found how to chose the right dye for building such multifunctional dyes

When chemistry meets neurons! Just dropped in @PNASNews Our game-changing paper on multifunctional fluorescent ligands for intracellular labeling. Luke Lavis and Pratik Kumar @prat_i_k built the epic tools; we got to unleash them! @JasonVevea & team nailed biotin-HaloTag for mitochondrial magic. My lab rocked the JQ1 version to shuffle chromatin in LIVE cells. First collab win for our Neuronal Cell Biology Division with Janelia—more to come! #Science #Neuroscience #ChemBio #scicomm #Fluorescence #HaloTag

Happy to share the lab’s latest research tagging psychedelic-activated neurons in mice. See the post below from first author @jessie_muir for a tweeprint on the work.
Thanks to wonderful collaborators @DEOlsonLab @LinTianPhD and to our reviewers/editor!

Excited to share the Kim Lab’s newest paper in @ScienceMagazine with Sophia Lin (twitterless) and @tinakim_neuro ! We look at circuit mechanisms of psychedelic action underlying therapeutic-like effects in the PFC. science.org/doi/10.1126/sc…

Really glad to have this work identifying the key role of PV-neurons in the ventral hippocampus in gating the anxiolytic actions of the serotonergic psychedelic, DOI, out in @NeuroCellPress @TIFRScience sciencedirect.com/science/articl…

And it’s out! Our lab’s very first paper is published today @naturemethods!
Our calcium-activated split-TurboID (CaST) can biochemically tag activated neurons within 10 minutes, enabling a molecular handle on functionally relevant cell ensembles: tinyurl.com/ddyecxze

Excited to share the first paper from our lab! tinyurl.com/5n7fvwvh We engineered a new kind of time-gated calcium integrator, CaST, that can rapidly and non-invasively tag activated neurons in vivo with a small, biochemical handle. What makes this tool special and unique? 1/6

Ok, 14 years after starting my lab, promoted to full professor! So @jess_cardin , time for a vacation?

I am happy to have contributed to this wonderful work by @actuallyeden during my previous post-doc in @johnalangray 's lab

@NeuroBill Thanks for your recommendations Bill, I would definitely consider DigitimerDS3 next, its looks great
English
@Raghava_Bio Sorry for not getting back to you. I thought I already had. I've used an iso-flex a lot. On paper they are great, but for me, the best is digitimer. DS3. The DS4 is very nifty, but I love the DS2s and DS3s. K.I.S.S.

@NeuroBill Hi
Can you help in understanding what causes this weird stimulus artefact? I get this sometimes, changing polarity works but the amplitude decreases
I am using ISO-Flex unit
English
@NeuroBill Hi Bill, did you miss this tweet from me earlier?
Thanks
English
@NeuroBill Hi Bill
I accidentally found the origin of the issue. I suspect the stimulus isolation unit (SIU) is the culprit here. These two traces are from the same cell 10s apart but with different SIUs. The graph on the right is a scaled version of the left one for better resolution

@Avishek92 @NolwennCloarec @letelliermathi1 @ebazbadillo Cool, what microscopy? Two-photon? I am planning for some slice imaging but we don't have a 2p in the lab. So thinking of other options.
English
@Raghava_Bio @NolwennCloarec @letelliermathi1 @ebazbadillo Thanks! Yes @Raghava_Bio this was a parasagittal section of 300um thick on the seeding time of slice for culture
English
This was fun participating in the contest thanks to @NolwennCloarec for arranging this. I also take this moment to say thanks to @letelliermathi1, @ebazbadillo & Agata Nowacka for the guidance to single cell electroporation

@NeuroBill And those traces are AMPAR-only currents with NMDAR and GABA blocked by AP-V (50uM) and Picrotoxin (100uM), respectively.
English
@NeuroBill I have been using Iso-Flex for close to a decade but have yet to have this problem. This is due to the capacitive transients generated by the SIU. The unit I am using is a brand-new one with all-new batteries!
Any suggestions?
