Letourneau receives prestigious NSF GRFP Fellowship. Congratulations to Jeff Letourneau, MGM Graduate Student in Lawrence David’s lab, on being awarded this fellowship. The NSF Graduate Research Fellowship Program recognizes and supports outstanding graduate students in NSF-supported science, technology, engineering, and mathematics disciplines who are pursuing research-based Master’s and doctoral degrees at accredited United States institutions. Jeff is interested in understanding how complex communities of microbes cooperate and compete in the breakdown of dietary fiber in the human gut. In his research, he is using in vitro models to explore how habitual fiber consumption and gut microbiome composition affect an individual’s capacity to derive health benefits from fiber supplementation. He is also leading an upcoming human study to test the effects of increased fiber intake on behavior and cognition.

Marchuk receives 2019 Research Mentoring Award for basic science research. Douglas Marchuk, James B. Duke Professor, has been announced as the 2019 recipient of the School of Medicine Basic Research Mentoring Award. The Research Mentoring Awards were created in 2009 to honor outstanding research mentors in the Schools of Medicine and Nursing. Winners of this award demonstrate excellence in numerous aspects of mentoring, including accomplishments of individual mentees, programs implemented by the mentor, or by exceptional creativity in mentoring.
Doug was nominated for this award by his current and former students, fellows, and faculty colleagues who highlighted the various ways in which Doug has mentored trainees and junior faculty alike. Doug was co-Director of the University Program in Genetics and Genomics from 2002-2009 and director from 2009-2014, as well as the founding Director of the Division of Human Genetics. He has been the course director of the Human Genetics course (MGM732) for many years and founded the highly impactful grant writing course (MGM702) that has benefited students across the basic sciences and engineering departments. In his own lab, Doug has mentored many undergraduates, graduate students, MSTP students, and postdoctoral fellows. His trainees have gone on to successful careers in academic research, academic administration, patient advocacy, and medicine. Doug is also a staunch supporter of his faculty colleagues, particularly junior faculty, advocating for their research programs and professional development and serving on tenure committees. Doug’s tireless dedication to education, mentoring, training, and science is inspiring.
This well-deserved award will be presented to Doug by Dean Mary Klotman at the annual Spring Faculty Meeting to be held at the Doris Duke Center, Duke Gardens on Wednesday, May 8th at 5pm.

Edgar will attend the Fungal Genetics Conference in Asilomar, CA this March. To read more, click here.
Lowe announced as Whitehead Scholar. Craig Lowe, PhD, Assistant Professor, was awarded a Whitehead Scholarship by the School of Medicine. Craig is the tenth MGM Faculty Member to receive this prestigious distinction. The Lowe Lab is working to understand the genetic basis of vertebrate adaptation and disease. We are especially interested in understanding the genetic differences that underlie unique aspects of human biology. Some of these genetic differences have given humans unique and wonderful abilities, but other parts of our genome leave us predisposed to certain diseases and disorders.

Brown and Gibbs received perfect scores on F31. Hannah Brown and Kyle Gibbs, two MGM graduate students received a perfect score of 10 on their most recent F31 submission. The title of Hannah’s project is, “Defining pH-Sensing in fungal virulence.” The research funded by this grant aims to explore how microbial organisms sense and respond to a change in environment in order to infect and cause disease. Specifically, I will study the human fungal pathogen, Cryptococcus neoformans and its ability to adapt to the more alkaline and warmer environment of the human lung as a way to understand this response. By better understanding how these pathogens manipulate themselves in order to better infect and coexist with the host, we aim to define new strategies to treat and clear microbial infections. The title of Kyle’s project is, “STAT3-dependent manipulation of host transcription and immune responses by Salmonella.” The research funded by this grant aims to determine both (1) how a novel Salmonella effector, SarA, drives the activation of the host transcription factor STAT3, and (2) how activation of STAT3, with accompanying host transcriptional changes, alters the host cell physiology to accelerate theintracellular replication of Salmonella, and thereby increase the virulence of sarA-containing Salmonella strains. Determining how SarA assembles a host signaling complex to phosphorylate STAT3 could provide a model for both other uncharacterized bacterial effectors and poorly characterized signaling by cytokine receptor intracellular domains. Understanding how, and to what end, SarA activates STAT3 during infection could open research into host-directed treatments for both infectious diseases and autoimmune disorders that are regulated by STAT3 signaling. Congratulations to both of them on this exciting news!
Dr. Matt Scaglione arrives at Duke on January 1, 2019. Matt Scaglione is currently an Assistant Professor in the Department of Biochemistry at the Medical College of Wisconsin and will arrive at Duke January 1, 2019 in the Center for Neurodegeneration and Neurotherapeutics and the Department of Molecular Genetics and Microbiology. From Al La Spada, the center director: “Matt’s postdoctoral work was done with Hank Paulson at the University of Michigan and focused on how proteins are selected for degradation by the chaperone-ubiquitin-proteasome system, with an emphasis on how this regulates the accumulation of pathological protein aggregates. Since starting his own lab in 2013, Matt has begun using the amoeba Dictyostelium discoidium as a model system to study an inherent mechanism of resistance to polyglutamine-driven protein aggregation. He has discovered a chaperone protein that uses an amyloid decoy domain to interact with polyQ-expanded proteins and target them for degradation by the proteosome. More recently, he has identified a chaperone protein that forms a biomolecular condensate via phase-phase separation can prevent protein aggregation in Dictyostelium. These are fascinating stories that have potential clinical implications for neurodegenerative diseases. Matt is using a variety of genetic and biochemical approaches and is extending his studies to mice and human cells.”
Jen-Tsan “Ashley” Chi, MD, PhD, Associate Professor in the Department of Molecular Genetics and Microbiology and lab recently published new findings on unmasking blood doping in athletes. Read more about the findings in the Duke Today news release. Read the published research here.
Davey awarded an AHA Fellwoship. Lauren Davey, Phd, a postdoctoral fellow in the laboratory of Raphael Valdivia, was awarded an American Heart Association Research Award. Lauren’s research focuses on Akkermansia muciniphila, an intestinal bacterium that eats mucus produced by its host. Colonization with Akkermansia is associated with health and its abundance is inversely correlated with cardiovascular disease risk factors such as diabetes and obesity. Akkermansia is a promising candidate for a novel probiotic, however, it remains poorly characterized. To better understand this fascinating bacterium, I am developing genetic tools to study the molecular mechanisms of mucin degradation, intestinal colonization, and interactions with other bacteria that inhabit the mucus layer. Using a combination of high-throughput DNA sequencing and colonization models, I am working towards identifying genetic factors required for Akkermansia survival in vivo. By investigating how Akkermansia interacts with the host and other gut microbes, I hope to contribute to efforts to leverage microbial ecology as a treatment for cardiovascular disease and obesity.
