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.
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...

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 😬.

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...

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.
Do you want to know how to develop water-soluble qubits operable in biologically relevant media? Look no further! 🔥
Thanks to @alexandrubg.bsky.social and Aliaksandra Lisouskaya (from ND) for their contributions to this manuscript.

A Conjugated Oligoelectrolyte Exhibiting Room Temperature Spin-Correlated Radical Pair Character for Biological Sensing
We report a water-soluble conjugated oligoelectrolyte (COE), Quantum-COE, exhibiting photogenerated spin-correlated radical pair (SCRP) behavior sensitive to the electric field of DNA, but not to that...

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'.

🎉 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...
Superconductivity in the Parent Infinite-Layer Nickelate ${\mathrm{NdNiO}}_{2}$
Undoped NdNiO${}_{2}$ exhibits superconductivity up to 11 K, challenging the assumption that doping is essential in layered nickelate superconductors.

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!

Last day of volunteering at IU Care Week. It was maybe as helpful for me as it was for the students: I could feel helpful without handing out work/assignments/grades. Just bagels and cream cheese, no added pressure or stress on anybody. And if you know me you know I love feeding people 😬😂.

Lived my dream of running a food cart at IU Care Week, serving students breakfast. Downside: my dream is not for me. My wrists are weak and hands are shaky.

Last year some finches built their next close to my feeders, on top of a wall. This week the old nest fell on the ground. What I didn't see last year was that the finches also used the cotton I left them for the nest! It looks like it must have been pretty comfortable.

This is my 'Ph.D Defense and Qualifying Exam Questions' notebook. I write down all my scary intimidating theorist questions on it as part of a student's Ph.D committee. Questions as scary as the monster drawn on it. 😤
