My experience is considerably different from the typical researcher – I come from a background in restaurant and retail management, having worked as an assistant store manager, general store manager, and district manager in well-known companies including Burger King and Starbucks, as well as independent restaurants like Menchanko-Tei. These seemingly disconnected employments have given me the complex ability to multi-task and maximize my time, which have been instrumental in my scientific career.
While juggling multiple responsibilities in my numerous jobs, I completed my BA and MA degree in Biotechnology at Hunter College, working with Dr. Paul Feinstein in characterization of odorant receptors in mouse olfactory neurons. Subsequently, I completed my PhD at Columbia University with Dr. Liza Pon working on identification of novel actin-mitochondrial interactions in regulation of cellular health and lifespan in the yeast model organism, S. cerevisiae. Throughout my research career, I also invested my time in developing my pedagogy, working as a teaching assistant and adjunct professor at several high schools, Kaplan, Hunter College, Columbia University, and College of Mount Saint Vincent.
In the Dillin lab, I work on investigating the impact of cellular stress responses on aging and vice versa. Primarily, I am focused on dissecting how quality control mechanisms dedicated to preserving the quality of organelles change during the aging process. Specifically, I am interested in quality control machineries involved in promoting the function and integrity of the actin cytoskeleton and the endoplasmic reticulum. Through large-scale genetic screens, my team is focused on mapping out the genetic architecture of cytoskeleton and ER homeostasis, and hope to eventually tie these webs together to identify inter-organelle quality control mechanism.
