We welcome Dr. Shimin Zhang as a Postdoctoral Scholar in our group. 🎉 She comes to us from Prof. Yuan Ping's group at U Wisconsin-Madison, and brings a wealth of experience in quantum many-body methods as applied to quantum impurities in solids, and photoluminescence.
Thankful for the support from the Department of Energy 🎉!

Passed by the office and took the grad students on a surprise lunch & asked them to practice their APS elevator pitch. Left to right: Varsha Kumari , me, Madison Genslinger, Md. Rajbanul Akhond.
Great overview and imo great for new students in electronic structure: pubs.acs.org/doi/full/10....
Nice article on our oxide work with quotes from our newest grad students! news.iu.edu/college/live...
Happy to announce that our group received a Department of Energy Early Career Research Program (DoE ECRP) award (Correlated Electron Materials with Novel Quantum Building Blocks, DOE DE-SC0026069; of 875K/5years) through the Theoretical Condensed Matter Physics program 🎉.
After the success of the 'tips on how to get a faculty job' videos (1.5K views on one of them 🎉 , and two invited talks on the topic!), I thought I would add a video with a few tips on my first few years on the tenure track: www.youtube.com/watch?v=9Cgy...
It could be good!
I haven't! But I'm also thinking I'm not sure I'd be comfortable posting the way I normally do (balance of student celebration and research) that normally gets engagement and helped me build my Twitter/LinkedIn account.
In my case posting here has no reach, basically. LinkedIn is not as dynamic but at least people are there. My guess is Blue sky features bigger accounts more to prevent trolls from taking over but it also means it's difficult to grow your account.
With the group members who are volunteering at ScienceFest! Madison Genslinger, Bipasha Samanta, and Varsha Kumari . The roses are meant to be dunked in liquid nitrogen and shattered 😬.
Many congratulations to Varsha Kumari , our PhD student (co-advised with @saraskrabalak.bsky.social ) who gave an amazing talk and an excellent closed door examination - as her entire committee agreed. 🎉 Very proud of you Varsha.
Come this Tuesday, October 21st at 4pm to see Varsha Kumari's talk, who will present her theory from our group and experiment in Sara Skrabalak's group, spanning correlated electrons from molecular orbitals and photoluminescence from lone pairs in solids! events.iu.edu/event/200948...
🎉 Congrats to Varsha Kumari & Julia Bauer on our paper, “Molecular Orbital Symmetry-Driven Trimer Formation in Kagome Correlated Electron Materials,” accepted in RSC Materials Chemistry C! 👏

Thank you!!
🎉 Honored to receive the 2025 Oxide Electronics Prize for Excellence in Research at #iWOE in Banff, Canada!
Grateful to my mentors, mentees & collaborators. This recognition reflects years of shared work on correlated materials & superlattices.
Thanks to @jenf.bsky.social for the pics!
We are happy to welcome Dr Mai Nguyen as a postdoctoral scholar into our group 🎉 ! She comes to us from UT Austin, and brings a wealth of expertise in electronic structure methods, including for high entropy alloy nanoparticles, battery materials, ionic transport and more!
New group picture.
We are searching for a new postdoc to join us. Plane wave DFT plus teach us something new (battery materials? Correlated electrons? Nanoparticles?) www.higheredjobs.com/faculty/deta...
Awesome!
In work led by undergraduate student Emily Ward, we show how to build Wannier functions that allow visualization and interpretation of lone pairs in a solid, as well as complex bonding interactions in metal oxyhalides. iopscience.iop.org/article/10.1...

My video on correlated electron materiasl has reached nearly 4K views! Glad so many people found it useful: www.youtube.com/watch?v=sp_f...
Many thanks to Bipasa Samanta, the postdoc in our group, who performed the calculations and taught me about the connection between bond angles in perovskites and conjugation in organic molecules, and to Ricardo for inviting us to this collaboration.
New work with my postdoc Bipasa Samanta on superconducting nickelates. After showing a remarkably strong correlation between in-plane Ni-O-Ni bond angles and Tc in La3Ni2O7, we investigate the effects of other factors (strain, correlations, layer number) on the likely Tc. arxiv.org/abs/2506.11427
We congratulate Varsha Kumari for winning a teaching award. She did a wonderful job teaching with me Intro to physical chemistry and the Surface Chemistry class. In one evaluation, a student answered the question 'How can she improve?' by saying 'Nothing. She's doing amazing'.
Awesome job Varsha Kumari and Bipasa Samanta presenting your work with a talk on trimer formation in Kagome materials and a poster on superconducting nickelates at the Midwest theoretical chemistry conference in Detroit!
🎉 Congrats to the MRS Student Chapter at Indiana University
MRS at IU especially 2024–25 President @michaelakloveless.bsky.social , for earning a mini-grant for Bringing SMILES! They'll 3D print glowing toys & teach photoluminescence at Science Fest this fall! 💡🧸 #SciComm #MRS
New work led by our excellent PhD student Varsha Kumari (with early contributions from Julia Bauer, now at Yale): we show that triangular cluster formation in Kagome multiferroics is driven by trimer orbital symmetry & intermediate correlation strength. arXiv: arxiv.org/abs/2505.13659
Happy to have contributed to this complex collaborative work - now in PRX - showing that infinite layer nickelate superconductors may be more different from cuprates than we thought: they may be superconducting even in the absence of doping: journals.aps.org/prx/abstract...
Congratulations to our student Emily Ward, who graduated with the highest award from the department, and pursued both theory and experiment as an undergraduate student. Her curiosity, drive, and kindness will be missed. We wish her good luck during her Phd at Princeton!
