His doctoral project will have a duration of three years, from October 2020 to December 2023. The project is funded by the University of Turin. His doctoral research is devoted to the Polish mystic Andrzej Towiański (1799-1878) and his Italian disciples.

After a vocational degree in graphic design (2015) and a one year of teacher training in History (2017), Tjalling received BA (2020) and RMA degrees (2022, cum laude) in Religious Studies, the last two both at the University of Amsterdam. During his RMA, he was a founding member of the HHP Student Association. His RMA thesis, supervised and assessed by Peter Forshaw and Liana Saif, was a reception history of elementals from the sixteenth to the late nineteenth century covering both natural philosophy and literature, investigating the significance of gender and its cultural transformations. His current PhD project at the HHP, supervised by Peter Forshaw and Wouter Hanegraaff, also deals with these beings, but instead mainly focusses on how they are embedded in the natural-philosophical context of the sixteenth and seventeenth centuries, now looking at the relationship between humanity and the natural world, and how understanding this aspect can contribute to the history and philosophy of ecology. His overall research interests include intermediary beings, alchemy, magic and Paracelsianism in modernity broadly construed (sixteenth to early twentieth century), and how these themes and schools of thought have influenced and have been influenced by things such as (natural) philosophy, spirituality, our relationship to the environment and other topics with a social component.
Brennan Kettelle holds a Research Master’s degree in Religious Studies, with a focus on Western esotericism (University of Amsterdam, 2021, cum laude), as well as a Master’s degree in Gender & Cultural Studies (Simmons University, 2018, cum laude). Her PhD project – supervised by Marco Pasi – investigates historical associations between the religio-mythic demoness Lilith and queerness within nineteenth-century literary, artistic, and occult discourses. Aiming to foster intersectional collaboration between queer studies and esotericism studies, Brennan is more broadly interested in examining both queer currents within esoteric literature, orders, and figures, as well as esoteric themes within queer subcultures, politics, and histories. As such, her current research also focuses on the lesbian-pagan poetess Renée Vivien (1877-1909), analyzing the occult influences of her queer, satanic oeuvre. Brennan’s other academic interests include nineteenth and twentieth-century occultism, sex magic, esotericism and politics, and conspirituality.
