Ola Hekselman is a Faraday Institution Entrepreneurial Fellow in the Department of Materials. Her primary research interests are in solid-state chemistry and electrochemistry, with a focus on new materials and technologies for energy applications. 

Ola's research concentrates on low-temperature chemical and electrochemical routes for lead recycling from lead-acid batteries. Ola's interests extend to material discovery for solid-state Li-ion batteries. This ranges from polymer, ceramic and hybrid electrolyte systems to organic electrodes. Ola combines her expertise in inorganic and organic synthesis with characterisation methods to tailor electrochemical, chemical and mechanical properties of the next-generation battery materials.

Before joining Dr David Payne's group and the RELAB project in December 2017, Ola was a Research Associate working with Dr Ainara Aguadero. Between 2014 and 2016, she was a Research Fellow in the Department of Materials at the University of Oxford, where she held an Academic Visitor position until 2017. Ola obtained her PhD in 2014 under the supervision of Prof. Peter G. Bruce at the University of St Andrews.
