Steve Cappell

I am interested in understanding the precise molecular events that allow cells to transition from G1 to S phase and enter the cell cycle. Specifically, I use quantitative and systems-level approaches to study the roles of CDKs and the ubiquitin ligases APC and SCF in regulating the G1/S checkpoint


Sean Collins

I am interested in understanding how cells use molecular signaling components to process spatial information from their environment. In particular, I am using systematic genetic approaches and automated imaging to study the directional sensing and chemotaxis of human immune cells.


Lin Gan

My research interests are understanding mTOR signaling and nutrient sensing from a global perspective as well as elucidating the mechanism of nutrient sensing at the molecular level


Arnold Hayer

Collective endothelial cell migration Collective cell migration is required for morphogenesis during development and for repair following injury. Directional signals guiding collective cell movement are thought to be transmitted mechanically between cells via cell-cell junctions. Using monolayers of primary human endothelial cells (HUVEC) as a model system, I study how forces applied to the junction locally by one cell are sensed by its neighbor and converted into biochemical signals.


Ariel Jaimovich

After being transcribed, mRNA can go through a variety of processes that control its translation into protein. I'm interested in using a variety of tools to visualize mRNA in fixed and living cells in order to learn more about the various aspects of translation regulation


Seth Malmersjo

I am interested in the molecular mechanism of mast cell secretion. Mast cells are key players in acute allergic reactions and allergic asthma. Upon activation by antigen stimulation, mast cells release their granule content, such as histamine.


Sabrina Spencer

I am interested in when and how cells choose between proliferation and quiescence. I have established time-lapse microscopy and automated tracking of cells expressing various cell cycle markers. Using this system, I am able to track individual cells through time as they approach this decision point and observe which cells choose to commit to another round of the cell cycle and which do not under various conditions and perturbations. I hope this work will extend our current understanding of the proliferation-quiescence decision and its deregulation in cancer.


Hee Won Yang

I am interested in understanding the signaling network in systems level. How signaling proteins induce signaling cascades, cross-regulate, and are correlated with each other.

Mingyu Chang

The rate of cell division is largely dictated by the amount of time individual cells spend in a non-dividing state before entering a cycle of cell division. My research focuses on dissecting the signaling pathways regulating cell-cycle entry.


Gautam Dey

I am developing fluorescent reporters to measure real-time changes in translation rates (regulated via untranslated regions of mRNA molecules or UTRs) in single cells. We are currently applying these reporters to the investigation of gene-specific translation control in the mammalian cell cycle. In a separate project, I am using the evolutionary history of the protein-coding human genome to identify conserved modules in signaling pathways and discover novel functions for uncharacterized human proteins.


Kyuho Han

Development of real-time translation reporter with single cell resolution to tackle mTOR pathway-mediated mRNA translation regulation.


Akiko Seki

How do cells response to extracellular stimuli? How are the signals beautifully orchestrated inside of a cell? To understand the questions, I'm studying 2 signal-induced cellular responses. One is looking at primary cilia disassembly by growth factor signal using single-cell imaging techniques. Another project is investigating how mTORC1 is activated by amino acid stimulation using biochemical approaches.


Amy Winans

During maturation, hippocampal neurons form a single axon and multiple dendrites. My work assesses the role of trafficking in this axon specification decision. Specifically, I'm examining the selective trafficking of Kinesin 1 into certain neurites and well as actin waves that move up and down the neurites of polarizing cells.
