All the best @tejashyam_k and keep up the good work in @DanielHurdiss lab.

@benubrata @AnRf @DST @DBTIndia Congratulations @benubrata and the authors 👏🎉

Excited to share our paper in Nature Communications! We show that PRMT5 localizes to mitochondria and regulates TFAM in mtDNA maintenance—revealing a new mitochondrial function for PRMT5. 🔗 nature.com/articles/s4146… Grateful to my students and @ANRF SUPRA @DST ⁦@DBTIndia⁩

Always nice to catch up with @s_ndutta @PenmatsaLab @MamataBangera and other em friends.

Double gain this week. Had a wonderful time @EMBO CEM3DIP 2026 cryo-EM workshop at @iitdelhi & @unescorcb. Also reconnected with my mentor Gabe Lander @LanderLab and did GO grid prep with him. Was fun to be a mentee again. Thanks @Icosahedral16 & @prem_s_kaushal.

@sshekhr @BiophysicalSoc @emorycollege @EmoryUniversity Congratulations @sshekhr 🎉👏

Incredibly honored to receive the Early Career Award in Mechanobiology by the Biophysical Society. @BiophysicalSoc @emorycollege @EmoryUniversity

Another one flew off today. We all said Good bye to @tejashyam_k with both joy and heavy heart as he heads to @DanielHurdiss lab at @UniUtrecht to start his PhD. We wish him all the best and looking forward to his success and an exciting journey ahead.

@AthiNaganathan @ChemBiochemUMD @CEGLAB_IISERBPR @IndiaDST @iitmadras Congratulations @AthiNaganathan and team. Wonderful work

Our latest work is out in PNAS! We show how protein mutations modulate different features of the native ensemble and not just stability. Collaborative work with Fushman group (@ChemBiochemUMD) and Arun @CEGLAB_IISERBPR. Funding from @IndiaDST @iitmadras pnas.org/doi/10.1073/pn…

Our lab will be represented by @Achyuthkrishnap at #BPS2026 in SF. Please attend the session he is presenting his work in on 24Feb at 10:45 AM in rooms 212-214. Thanks to @BiophysicalSoc for providing the opportunity and @ANRFIndia for the travel support. @ccmb_csir

@DipaLab_IISc Many congratulations Dipshikha @DipaLab_IISc 👏 🎉

@AthiNaganathan @BiophysJ @iitmadras @iitmbt Congratulations @AthiNaganathan and the authors.

Sequence-structure-ensemble connections extracted through the WSME model with application to kinases. Work by Dhruv is now published in @BiophysJ Funding support from @iitmadras @iitmbt

Biology through an EM-lens 2026 started in a great mood. Intense teaching and interactions. @bose_institute @ANRFIndia @IndiaDST @KaustuvSanyal

@s_ndutta @saikatLab

@tamal_das @marwaha_rr @India_Alliance @TIFRH_buzz Congratulations @tamal_das @marwaha_rr for the wonderful work

Excited to share our latest work led by a very talented postdoc @marwaha_rr : nature.com/articles/s4146… ... Ritu uncovered an unexpected role for lysosomes in regulating leader cell emergence during collective cell migration. We thank @India_Alliance @TIFRH_buzz for support 🙏

@kellogg_liz @Mel_Ohi_lab Congratulations Melanie @Mel_Ohi_lab 👏🎉

As 2026 chair of the Biophysical Society Cryo-EM subgroup, I am thrilled to announce that Dr. Melanie Ohi has been selected as the recipient of the June Almeida Award: an honor recognizing established women scientists whose leadership, scholarship, and mentorship have profoundly shaped the field of cryo-electron microscopy (cryo-EM). The award celebrates the legacy of June Almeida, a pioneering electron microscopist who revolutionized immune electron microscopy by showing that viruses could be identified directly in cell culture without purification. Her groundbreaking work led to the first identification and naming of the coronavirus, inspired by its crown-like appearance. A visionary described by colleagues as someone who “extended the range of the electron microscope to new limits,” Almeida made transformative contributions despite never having had the opportunity to attend university, and her work went largely unrecognized until the SARS-CoV-2 pandemic brought her brilliance to the fore. The Almeida Award honors her impact and celebrates the outstanding women scientists whose vision and perseverance continue to advance the field of cryo-EM. Dr. Melanie Ohi embodies the spirit of this award. A pioneering force in single-particle cryo-EM, she is widely respected for pushing the boundaries of both the method and its biological applications. At a time when the field dismissed many complex structures as “blob-ology,” Dr. Ohi boldly tackled highly dynamic assemblies such as the spliceosome and the anaphase-promoting complex. Her research has profoundly advanced our understanding of bacterial pathogenesis through structural insights into elaborate bacterial secretion systems, including the Type IV secretion systems of Legionella pneumophila and Helicobacter pylori. These discoveries have reshaped fundamental concepts in microbiology and structural biology. Across her career, Dr. Ohi has demonstrated the creativity, rigor, and collaborative spirit that define the very best of our field. Her impact extends far beyond her scientific achievements. Dr. Ohi has played an essential role in building and sustaining the cryo-EM community—directing numerous workshops, organizing conferences, and serving on influential advisory boards. She is an exceptional mentor to postdoctoral fellows, graduate students, and undergraduates, and she is admired as a generous colleague whose clear-eyed guidance and willingness to help uplift the work of others have strengthened the entire discipline. Her commitment to expanding access to cryo-EM has had lasting effects on the broader scientific honoring Dr. Ohi, we also celebrate the legacy of June Almeida, whose perseverance and vision laid the groundwork for modern electron microscopy. Dr. Ohi’s achievements continue this tradition, inspiring the next generation of microscopists and driving forward the transformative impact of cryo-EM. Please join us in congratulating Dr. Melanie Ohi on this exceptionally well-deserved recognition. She will be giving the Almeida award lecture at the Biophysical Society Cryo-EM subgroup, Feb 21 from 1 - 5:30 pm.
