First person - Brandy Hyndman and Mathieu Crupi.

First Person is a series of interviews with the first authors of a selection of papers published in Journal of Cell Science, helping early-career researchers promote themselves alongside their papers. Brandy Hyndman and Mathieu Crupi are co-first authors on 'Differential recruitment of E3 ubiquitin ligase complexes regulates RET isoform internalization', published in Journal of Cell Science. Brandy is a Research Associate and Mathieu is a PhD student, both in the lab of Dr Lois Mulligan at the Queen's University Cancer Research Institute in Kingston, ON, Canada, investigating the ubiquitylation and trafficking of RET receptor tyrosine kinase isoforms.
