Dana DIC Award

November 2026

Congratulations to Dana Feldman for being chosen for the 2027 ACS Division of Inorganic Chemistry Award for Undergraduate Research. This is a very prestigious honor, and Dana was chosen out of all college seniors in research-intensive institutions in the USA. Kudos!!

hiding hydrides say hi

September 2026

Ryan Donnelly’s recent work on crystallography of a cobalt-hydride was written up for feature by the Chemistry Department. Great work Ryan!! https://chem.yale.edu/posts/2026-09-17-yales-microed-brings-hidden-hydrogen-into-focus

teaching awards for Olga and Ryan

August 2026

Very proud of Olga Zubarieva and Ryan Pinard, who won departmental teaching awards yesterday, and Chandler Woo who was the co-organizer of the Yale Chemistry Symposium. Three superstars reaching their second year of graduate school!

Dana's paper on iron-salen complex

July 2026

Congratulation to Dana, whose paper on a reduced iron-salen complex was published today in Chemical Communications. This was totally her idea and execution, which is really impressive! She showed that a complex in the formal iron(I) oxidation state is better described as iron(II) with a one-electron reduced (non-innocent) salen ligand. This was accompanied by a very thorough computational analysis including a new calibration set that is particular for salen complexes of iron. A very thorough story - well done!

Hydride and Seek

June 2026

Congratulations to Ryan Donnelly, whose outstanding crystallographic paper has appeared in ACS Central Science. Ryan compared the structures of a cobalt-hydride complex using neutron, X-ray, and electron diffraction with various types of refinement. He found that electron diffraction actually gives better location of the hydride than quantum refinement with X-ray data. So, even though the most attention has been paid to the small size of crystals for electron diffraction, another advantage is its ability to locate H atoms accurately!

Also, big kudos for the article title, which is another demonstration of Ryan’s punniness. 

Teddy will be Chair

June 2026

Congratulations to Teddy Gerard for being elected co-chair of the 2028 Gordon Research Seminar on Metallocofactors. He will be teaming up with our longtime collaborator Ira Mathe to organize and run this prominent student conference. It will be great!

Dana wins Goldwater Scholarship

March 2026

A huge congratulations to Dana Feldman, who has won a Goldwater Fellowship. This is a super-selective program that recognized the top 454 undergraduates in all STEM fields in the U.S. Wow!

Poster award for Ryan

February 2026

Congratulations to Ryan Donnelly, who won a poster prize at the Bruker-MIT Symposium on Crystallography. He presented his work comparing data on a new compound using neutron, X-ray, and electron diffraction methods to determine the best way to locate hydrides. Great job Ryan!

Two papers from Dana

February 2026

A massive congratulations to Dana Feldman, who has recently had two first-author publications published during her third year of undergraduate study at Yale. The first, in Chemical Communications, was the result of summer research in 2024 with Ulf-Peter Apfel in Bochum, Germany, and explored metal-salen complexes in gas diffusion electrodes. The second, in Journal of the American Chemical Society, was the result of summer research in 2025 with Cyrille Constentin in Grenoble, France, and explored the control of electrocatalytic CO2 reduction by cobalt complexes. Dana is working on research in our group that will lead to several more papers. Great job, Dana!!

Welcome to Kaeden

February 2026

Welcome to Kaeden Teindl, who has joined the Holland Group for postdoctoral research after Ph.D. work at the University of British Columbia with Eva Nichols. We look forward to further development of our electrocatalysis programs with benefits from Kaeden’s expertise and enthusiasm!
