Mimi Xie Passed Qualifying Exam

Anthony is the newest postdoc in the lab. Anthony comes to us from the MIT Mechanical Engineering PHD program.

We have a number of new additions to the lab including postdocs Jasmin Imran Alsous and Nat Clarke, graduate students Anna Yeh and Jaclyn Camuglia, undergraduates Prateek Kalakuntla and Jennifer Nwako, and technician Vardges Tserunyan.

Congratulations to graduate student, Mimi Xie, for her publication “Intracellular signalling and intercellular coupling coordinate heterogeneous contractile events to facilitate tissue folding” in Nature Communications. In the paper, Mimi showed that cells exhibit three classes of contractile events, unconstricting, unratcheted, and ratcheted. Mimi demonstrated that cells undergo transitions between different classes of contractions, going from unconstricting or unratcheted contractions to ratcheted contractions. A transcription factor that regulates this developmental stage is important for the proper order of contractile events. It is important for cells to generate ratcheted contractions because this promotes cooperation between cells.

Congratulations to postdoc, Soline Chanet, for being awarded an EMBO Long-Term Fellowship.

Congratulations to Jaci Camuglia and Anna Yeh on passing their Ph.D. candidacy exams! Excited to see what research directions we go in over the next few years.

Congratulations Mimi Xie for publishing her work “Loss of Gα12/13 Exacerbates Apical Area-dependence of Actomyosin Contractility” in Molecular Biology of the Cell! Mimi showed how apical actin density can depend on apex size. Suppressing this dependence is important to coordinate contractility across a tissue.
