Presented a seminar to the UCSD Electrochemistry Society Student Chapter
I had a great time presenting some work, both old and new, to the UCSD ECS student chapter. It was great sharing some uses of NMR for energy materials, as well as promoting a recent paper published with the very talent Schoetz group at UIUC about deconvoluting cyclic voltammograms to uncover reaction mechanisms!

DTU Alliance Fellowship
I was recently awarded funding for a PhD project in collaboration with Rachel Huang at EPFL to study transport processes in redox flow batteries.

Otto Mønsted Fond Travel Award
I was grateful to receive a travel grant from the Otto Mønsted foundation to support my attendance at the ENC in Pacific Grove, CA. This award enabled me to share ideas and receive feedback from colleagues on a study of large-scale decoupling in liquid NMR.

New Paper on Quantitatively Deconvoluting CVs to Understand Charge Storagage Mechanisms
A new paper was published as a tutorial for disentangling charge storage mechanisms by analysing cyclic voltammograms across multiple rates. I was very glad to collaborate again with Prof. Schoetz at UIUC and her incredibly talented team. The paper is open access and links to code and GUIs to perform the analysis yourself on your own data. Hopefully this is of great use to the electrochemistry community at large!

Danish NMR Meeting 2026
I had the opportunity to present work from a recent paper from my postdoc, co-led by Prof. Oscar Nordness, at the 2026 Danish NMR meeting. Here, I got to meet many colleagues in the Nordic NMR community and showcase some nice electrophoretic NMR results.

Hiring in the MR-e group
The MR-e group is hiring a PhD student to study energy materials (primarily electrolytes) using a combination of NMR spectroscopy and electrochemistry. The project involves using NMR methods to probe ion transport and ion interactions, in addition to developing operando methodologies to understand these phenomena further under non-equilibrium conditions. The deadline to apply is November 7th 2025. Please view the posting (https://efzu.fa.em2.oraclecloud.com/hcmUI/CandidateExperience/en/sites/CX_2001/job/5903) for full details!

Starting as Assistant Professor in DTU Chemistry
Today I have begun my faculty journey, starting as a new assistant professor in the chemistry department at the Danish Technical University (DTU). My group, the Magnetic Resonance and Electrochemistry (MR-e) Lab, will combine the worlds of magnetic resonance tools like NMR spectroscopy and MRI with electrochemical methods for the purpose of studying battery materials. Our goal is to build a deeper understanding of electrolytes by non-invasively probing them under non-equilibrium conditions, thereby enabling us to capture valuable insights of systems not at rest.

Two ACS Macro Letters Papers Published
Two separate co-author papers have just been published in ACS Macro Letters, one led by Rahul Sujanani, and the other by James Bamford. Rahul's study investigates the influence of polymers under moderate hydration conditions, far from the well-studied extremes of rigorously dry, and highly swollen. In this we show the changes in conductivity and ion transport as a function of hydration, controlled by a bespoke setup, designed by Phong Ngyuen. This work demonstrates a crossover point in the relationship between hydration and conductivity that is defined by the hydration number of lithium ions. In James' study, we show that lithium ion transport in a polymer with a pendant imidazole group can be improved by quaternization of the imidazole to imidazolium. This improvement is maintained even after Tg normalisation, and is further punctuated by an inverse-Haven ratio greater than 1.

Presentations at SCUM and AIChE
In a very busy week, I had the opportunity to present at both the Southern California Users of Magnets (SCUM) meeting, and the American Institute for Chemical Engineers (AIChE) annual meeting. At SCUM 2024, I presented some of the new work from our group using spatially-resolved NMR methods for direct measurements of thermodynamic phenomena, namely partitioning. I demonstrated this capability through measurements of the octanol-water partitioning coefficients of different solutes, in addition to using NMR profilometry to visualise intensity maps of water moving across membranes. At AIChE, I was proposing my research vision as a faculty candidate. AIChE was an excellent opportunity to meet and network with my peers across a range of disciplines, I always cherish attending talks outside of my comfort zone! For anyone I met this week, please stay in touch. I'm always happy to discuss research, especially ways to incorporate NMR spectroscopy into your work!

Harrison's Electrochimica Acta Paper Published
A study borne from my PhD work investigates the effects of mass transport and its interplay with electrochemical kinetics for aluminium-organic batteries. The study purports that there are two competing mechanisms in aluminum-quinone batteries, one that exists under high flux of intercalants, and the other under low flux. The mechanisms are dubbed concurrent and sequential, with these names relating to the ordering of the two-step electronic reduction and corresponding charge compensation. The concurrent mechanism occurs when the electrochemical Damköhler number is small (e.g., under high flux or low rates), and is ordered as electronic reduction-complexation-electronic reduction-complexation; the sequential mechanism by comparison occurs under conditions where the Damköhler number is large, and is ordered electronic reduction-electronic reduction-complexation-complexation. The key difference is that the uncompensated semiquinone form (after the first electronic reduction) is reduced at lower discharge potentials than the ionically compensated semiquinone. These mechanisms can be considered like putting on socks and shoes, you can go sock-shoe-sock-shoe (concurrent, small Dael), or sock-sock-shoe-shoe (sequential, large Dael). This study has consequences to any multielectronic organic electrodes, and tests multiple methods to affect Dael, all to the same conclusion.
