Another PhD defence @UEF Aerosol Physics Group: Irfan Muhammad defending his thesis on modelling aerosol effects on climate. Pontus Roldin (the Opponent) doesn’t let him off easy. And @harrikokkola.bsky.social (the Custos) sweating there in the middle.

Lejish Vettikkat doing excellent job with defending his doctoral thesis on the emissions of biogenic VOCs. Siegfried Schobesberger acting as a custos as a first time (and doing it like a pro!). Prof Steffen Noe is running the show as an opponent. 👌
