Research Interests

Dr. Voeltz's lab is interested in understanding how ER structure and dynamics are regulated and the role of ER contact sites in regulating the structure of other organelles in health and disease. Over the past several years her research has revealed surprising roles for ER contact in defining the position where mitochondria, endosomes and even membrane-less organelles like RNP granules undergo constriction and division. On mitochondria, the lab further discovered that both fusión and fission machineries co-localize to the same ER contact sites that they refer to as dynamic nodes. Her current research goals are aimed at unraveling the factors, functions, and mechanisms of ER-mediated organelle constriction, fission and fusion. Her lab further aims to forge a link between basic biology and disease. For example, she is studying how ER shaping proteins contribute to viral replication center formation and are probing whether ER contact sites serve as conduits for RNA virus trafficking through cytoplasmic organelles. Finally, her work is addressing how ER patterning by membrane shaping proteins during neuronal differentiation and growth guides the distribution of the associated microtubules and other organelles in health and disease.
