Studies suggest the ER is involved in neurite outgrowth, neurotransmission, and synaptic plasticity; however, the cell biology of the neuronal ER remains under-investigated. These gaps are crucial because mutations in genes that shape the ER can lead to neurodegenerative diseases, such as Hereditary Spastic Paraplegia (HSP). The importance of understanding synaptic ER function is further highlighted by the fact that HSP disease progression originates at upper motor neuron synapses. Altered ER function is also linked to other neurological diseases, such as Alzheimer\u2019s Disease, making my research relevant to a range of neurological conditions.<\/p>\n<p>&nbsp;<\/p>\n<p>Using the <em>Drosophila<\/em> larval neuromuscular junction (NMJ) as a model synapse, my lab will explore three aspects of ER biology in healthy and diseased neurons: the relationship between ER structure and function, ER structural dynamics, and local regulation of synaptic ER function. These research areas encompass fundamental questions that undergraduates can access experimentally, while maintaining high relevance to human neurodegenerative diseases. Through this work, students will grow as independent researchers by learning to dissect complex biological pathways using genetic approaches, including RNAi and CRISPR-based screens.<a href=\"https:\/\/www.bates.edu\/faculty\/profile\/monica-quinones-frias\/fig-1_8-31-25-copy\/\" rel=\"attachment wp-att-8369\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8369 size-full\" src=\"https:\/\/www.bates.edu\/faculty\/files\/2026\/07\/Fig.1_8-31-25-copy.webp\" alt=\"\" width=\"2000\" height=\"530\" srcset=\"https:\/\/www.bates.edu\/faculty\/files\/2026\/07\/Fig.1_8-31-25-copy.webp 2000w, https:\/\/www.bates.edu\/faculty\/files\/2026\/07\/Fig.1_8-31-25-copy-400x106.webp 400w, https:\/\/www.bates.edu\/faculty\/files\/2026\/07\/Fig.1_8-31-25-copy-900x239.webp 900w, https:\/\/www.bates.edu\/faculty\/files\/2026\/07\/Fig.1_8-31-25-copy-768x204.webp 768w, https:\/\/www.bates.edu\/faculty\/files\/2026\/07\/Fig.1_8-31-25-copy-1200x318.jpg 1200w, https:\/\/www.bates.edu\/faculty\/files\/2026\/07\/Fig.1_8-31-25-copy-1536x407.webp 1536w, https:\/\/www.bates.edu\/faculty\/files\/2026\/07\/Fig.1_8-31-25-copy-200x53.webp 200w\" sizes=\"(max-width: 2000px) 100vw, 2000px\" \/><\/a><\/p>\n<h2>Publications<\/h2>\n<ol>\n<li>\n<div class=\"csl-bib-body\">\n<div class=\"csl-entry\"><span style=\"text-decoration: underline\"><strong>Qui\u00f1ones-Fr\u00edas, M\u00f3nica C.<\/strong><\/span>, Dina M.
