个人简介

Dr. Neal received her Ph.D. from U.C. Los Angeles in 2013 after working in the laboratory of Dr. Carla Koehler. She then carried out her postdoctoral studies at U.C. San Diego in the laboratory of Dr. Randolph Hampton. She was the recipient of the Burroughs Wellcome Postdoctoral Diversity Enrichment Award and Ruth L. Kirschstein NRSA Postdoctoral Fellowship. Dr. Neal joined the faculty in 2018.

研究领域

Life is harsh, and hard on protein structure. Continuously-produced misfolded proteins represent a threat to proper cell and organ function. To survive this threat, organisms are equipped with quality control systems to maintain properly folded proteins; a process known as protein homeostasis. For the past two decades, it has become increasingly clear that protein homeostasis is critical to the health of cells and organisms. Defects in protein homeostasis underlie many of the most pressing maladies, including aging, cancer and neurodegenerative diseases. Our research strives to understand the basic biology of protein homeostasis and how organisms use quality control pathways to mitigate this universal biological stress. There are three questions that motivate our research: How do cells maintain protein homeostasis? How do changes in protein homeostasis lead to pathology? Can modulation of protein homeostasis be used to treat disease? Our research aim is to understand the cellular and tissue-specific roles of factors involved in protein quality control pathways, with a particular emphasis on the pathways that detect and specifically destroy these dangerous molecules. An understanding of these pathways allows us to define the mechanisms that protect the organismal proteome in health and disease, and eventually devise methods to harness cellular quality control to modify the proteome in the laboratory and the clinic. As a first step towards this goal, we are focused on discovering and studying proteostasis pathways in yeast, mammalian cells and zebrafish, allowing us to synergistically capitalize on the investigative strengths that each has to offer. We take advantage of the laboratory’s unique set of skills in genetics, biochemistry, functional genomics, cell and molecular biology to extend these lines of inquiry and to train the next generation of scientific leaders.
