First Person is a series of interviews with the first authors of a selection of papers published in Disease Models & Mechanisms, helping early-career researchers promote themselves alongside their papers. Elin Schoultz and Ellen Johansson are co-first authors on ' Tissue architecture delineates field cancerization in BrafV600E-induced tumor development', published in DMM. Elin is an MD, PhD student in the lab of Mikael Nilsson at Sahlgrenska Centre for Cancer Research, Gothenburg University, Gothenburg. She has a great interest in the thyroid gland in particular, and the mechanisms of tumor development, progression and treatment associated with epithelial carcinomas in general.
