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.

🎉 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 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'.

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

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. 😤

In work now in ACS Nano, we showed how magnetic order propagates in a complex system: double perovskite superlattices! Amazing experimental work by Jonathan Spring and Marta Gibert who invited me to work on this; I just wrote some scripts in Matlab: pubs.acs.org/doi/10.1021/...

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...
