ADA Postdoctoral Fellow

Greg is an American Diabetes Association (ADA) postdoctoral fellow studying connections between sex hormones, mitochondrial metabolism, stress signaling, and epigenetics in macrophage inflammatory responses. He grew up enjoying the outdoors and playing sports in the Village of Greenwood, NE, and attended Nebraska Wesleyan University in Lincoln. Inspired by the amazing & supportive faculty, he became interested in research at the interface of molecular biology, chemistry, and the immune system. He spent two summers in Rob Kuchta’s lab at the University of Colorado in Boulder, synthesizing dNTP analogues and measuring their incorporation into DNA by human and viral polymerases to understand enzyme fidelity. He also spent one summer in Nilabh Shastri’s lab at UC Berkeley as part of the Amgen Scholars Program studying the mechanisms by which intracellular peptides are processed for presentation by MHC Class I molecules to CD8 T cells. After graduating with degrees in Biology and Chemistry, he joined Mark Schlissel’s lab at UC Berkeley to study molecular mechanisms by which gene expression is regulated in the developing immune system as part of the Molecular & Cell Biology graduate program. In the Saijo Lab, Greg enjoys paying forward the scientific mentorship he received by mentoring UC Berkeley undergraduates and getting them excited about science at Berkeley and beyond. Outside of lab, Greg enjoys carbohydrates and jogging.

Laura Craciun
(she/her/hers)
lcraciun4@berkeley.edu
Elizabeth Roboz Einstein Fellowship 2017
University of California Dissertation-Year Fellowship 2020

Laura is a sixth year PhD candidate in the Molecular and Cell Biology program. She grew up in a small town outside of New York City, which she then moved to for college at New York University. In college, she studied both neuroscience and art. Her research career began in Dr. Adam Carter’s lab, where she was lucky enough to observe cutting-edge techniques that got her hooked on neuroscience. As a BP-ENDURE fellow, she continued to expand her neuroscience research by spending a summer in Dr. Barry Conner’s lab at Brown University, and another summer with Dr. Ronald Holz at the University of Michigan. Now at Berkeley, she studies how astrocytes can shape neural circuits during development and how perturbing this role can lead to diseases like autism. She has additionally started a project that explores the role of transition metals during neuroinflammation in collaboration with Chris Chang’s lab, in the hopes that at least one of these projects will work out before graduating. Outside of lab at Berkeley, Laura is involved with Getting into Graduate School, the McNair Scholars Program, and the MCB Inclusion Leaders, which are programs that aim to create a more equitable scientific community. Her other non-lab related hobbies include but are not limited to: talking about animals, reading fantasy novels, pretending to be outdoorsy, and tasting wines to prepare for the vineyard she fantasizes about owning one day.

Madeline Arnold
(she/her/hers)
madeline_arnold@berkeley.edu
ARCS Scholar 2017
NSF-GRFP Fellow 2018

Madeline is a fourth year PhD student in the Molecular and Cell Biology program. She grew up in rural Wisconsin, where she picked up a love of fresh black raspberries and quiet snowy days. She went to Carleton College in Minnesota, and became interested in research after taking a genetics lab class and later working with yeast in Dr. Stephan Zweifel’s lab. She then moved to the DC area to gain more research experience as a postbac at the NIH, working with mice and zebrafish to understand the pathophysiology of inborn errors of metabolism and develop gene therapies. Now in the Saijo lab, Madeline is interested in understanding how the immune system impacts brain development and behavior, and examining sex differences in this context. She’s also interested in the sociology of science and understanding which voices are heard or unheard in science, and how the way we study and talk about science impacts people. As a queer white woman, she aims to use her privilege to make STEM research and teaching more inclusive. Madeline serves on UC Berkeley’s CCRT committee working on prevention and response to sexual harassment and assault, the iMCB Conference Team, and recently started the MCB Distance Learning Task Force to address the challenges of remote learning. Outside of lab, Madeline enjoys cooking elaborate meals, gardening, cooperative board games, car camping, ceramics, Ultimate frisbee, and social dancing.

Matt Davis
(he/him/his)
mattd@berkeley.edu
NDSEG Fellow 2020

Matt is a PhD candidate in the Helen Wills Neuroscience Institute. He grew up in a rural area near Columbus, Ohio before moving to Atlanta, Georgia to attend Emory University. In 2017, he completed his B.S. in neuroscience and behavioral biology while working in the labs of Donna Maney and Kim Wallen. There he studied the neuroendocrine bases of song learning in developing zebra finches, and the influences of estrogens on behaviors of songbirds and humans. Now, Matt is melding molecular, systems, and evolutionary neuroscience into his research. He is interested in how embryonic microglia shape specific circuits that encode social behaviors of mice, as well as how inter-species variation in social behavior has resulted from the evolution of developmental mechanisms that shape brain architecture. Matt himself is a highly social creature, and recently started giving lessons in basic brain science to local first graders. He’s often engaged in friendly contests of frisbee and soccer, shares guitar grooves with his fellow jam rock and metal enthusiasts, and enjoys adventuring in the mountains.

UNDERGRADUATE STUDENTS:

Kevin Fang
Kevin is currently a senior majoring in Molecular Cell Biology (Immunology track) and Economics. He is working on his honors thesis with Matt to study how microglia affect the development of neural circuits. Outside of the lab, Kevin enjoys playing tennis, trying new restaurants (the world ending put a dent in these plans), and watching sports with friends.

Rida Khan
Rida is an Integrative Biology major working on her Honors Thesis with Greg to understand how stress influences macrophage mitochondrial morphology and inflammatory responses. She is currently applying to medical school.

Sandra Muroy, PhD 2019
Sandra joined the Saijo lab in 2017 and her dissertation work focused on elucidating the function of a completely novel transcriptional repressor of microglial inflammation – PHD finger protein 15 (Phf15). Her worked showed that Phf15 regulates both the antiviral response and pro-inflammatory cytokine production under basal and signal-dependent (Toll-like receptor) activation and controls the magnitude and duration of the microglial inflammatory response. The function of this repressor may be important in neurodegenerative conditions like Parkinson’s disease and Alzheimer’s disease where microglia-driven neuroinflammation has emerged as a key driver of pathology. Currently, Sandra is independently consulting on various projects providing bioinformatic analysis of high-throughput sequencing data.
