EPR: Illuminating the dance of electrons, unlocking the secrets of molecular choreography
Christiane R. Timmel
Professor of Chemistry
Why did you start with EPR research? and/or Who is your favorite EPR researcher?
I was drawn to EPR research largely due to the influence of Professor Keith McLauchlan, FRS, a luminary in time-resolved EPR and spin polarization phenomena. Keith's remarkable scientific contributions, recognized by multiple prestigious awards including the Gold Medal of the IES and election to the Royal Society, were matched by his generosity as a mentor. His guidance was pivotal when he bequeathed part of his lab to me and invested time in my experimental training, selflessly nurturing my skills alongside Peter Hore, another McLauchlan protégé. Keith's approach to mentorship, focusing on fostering talent for the collective good rather than personal gain, made him a true role model. I aspire to emulate not only his scientific excellence but also his dedication to empowering the next generation of scientists.
What if you were a faculty job candidate today with EPR expertise? Make your case.
As an EPR expert, my vision is to establish a multidisciplinary EPR center at a forward-thinking university. My tenure at Oxford coincided with an EPR renaissance, where the field flourished, particularly in new materials research like photovoltaics and LEDs. Collaborating with esteemed colleagaues, we created a world-class EPR facility—a pinnacle of my career. I aspire to replicate this success, showcasing EPR's capabilities to colleagues, nurturing new talent, and integrating EPR's rich potential into diverse research streams. It's a mission that I'm passionate about continuing.
Give us a high-level elevator pitch why EPR is a hot topic today?
EPR is a dynamic field integral to numerous research areas such as medicine, quantum computing, and materials science. Its relevance is underlined by a substantial rise in scholarly impact, underscoring its indispensability in science departments globally. EPR's unique leverage lies in exploiting electron spin properties, granting profound insights into quantum phenomena. Its versatility extends from probing protein architectures and their interactions to propelling innovations in green chemistry and molecular electronics. With the rapid evolution of technology, EPR is key for any research entity seeking to lead in scientific innovation. Indeed, understanding the molecular world is intrinsic to EPR, making it not just a scientific tool but a fundamental aspect of scientific inquiry itself. If science is our business, EPR is our currency.
What is your favorite EPR experiment and why?
My favorite EPR experiment is time-resolved EPR, which studies photogenerated spin polarization. This technique is particularly fascinating when paired with optical spectroscopy, showcasing EPR's strength in collaborative, multidisciplinary investigations akin to teamwork in science.
What are experiments of the past worth revisiting to solve today's problems?
In addressing today's scientific challenges, there's a wealth of EPR experiments from the past that serve as a valuable resource. The beauty of EPR research lies in its strong foundations, which need no reinvention but rather a robust dialogue across generations and disciplines. Time-resolved EPR and spin polarization, alongside techniques like RYDMR (Reaction Yield Detected Magnetic Resonance), are just some examples of areas ripe for revisitation. Pioneering works from the '70s, '80s, and '90s by notable scientists such as Fessenden, Feher, Hoff, Hore, Kaptein, Kothe, Levanon, Lubitz, Norris, McLauchlan, Molin, Pedersen, Salikov, Takui, Möbius, van der Waals, Wasielewski, and Weber, have established a comprehensive library of techniques and theoretical frameworks. This treasure trove is now at the disposal of a new generation of EPR researchers, who can harness these classic studies to propel time-resolved EPR into a new era and solve contemporary problems with time-honored wisdom.

EPR: Directly imaging cellular oxygen levels to outsmart cancer and unlock new frontiers
Martyna Elas
Professor of Chemistry
Give us a high-level elevator pitch why EPR is a hot topic today?
EPR spectroscopy is useful tool for structural studies, oxidative stress and oximetry and many more.
What is your favorite EPR experiment and why?
There are many examples - in the oximetry field the first experiments were cleverly designed, like Subczynski et al 1986. More recent achievements I admire are large scale oxygen imaging experiments like hypoxia boost irradiation Gertsenshteyn et al, 2023.
