Research

Membranes are the bags that hold cells together. Within eukaryotic cells (like yours and mine), sub-compartments are formed by organelle membranes to allow specialized structures. The Ader Lab seeks to uncover how cells build and maintain these compartments. Projects in our lab investigate how cells maintain their existing compartments during dynamic cellular processes (such as nuclear envelope remodeling during mitosis) as well as how cells build compartments from scratch (such as plasma membrane biogenesis in fungal meiosis). We approach these investigations using a variety of techniques, such as live-cell fluorescence microscopy and correlative light and electron microscopy (CLEM) of the model yeast, S. Pombe.
