First person – Tiantian Ji and Lina Zhang

First Person is a series of interviews with the first authors of a selection of papers published in Disease Models & Mechanisms (DMM), helping early-career researchers promote themselves alongside their papers. Tiantian Ji and Lina Zhang are co-first authors on ‘ Dynamic MAPK signaling activity underlies a transition from growth arrest to proliferation in Drosophila scribble mutant tumors ’, published in DMM. Tiantian and Lina are both PhD students in the lab of Yan Yan at The Hong Kong University of Science and Technology Clear Water Bay, Hong Kong. Tiantian is investigating tumor heterogeneity and dynamic signaling activity during tumor progression, and Lina is investigating the mechanism of dynamic MAPK signaling during fly tumor development.
