Ph.D.: Jorge Galan, Ph.D., Yale University
Postdoc: Jeffery Cox, Ph.D., UCSF
Interests: My lab is broadly interested in regulation of host innate immune responses in macrophages during intracellular bacterial infection and the macrophage/Mycobacterium tuberculosis host- pathogen interface. We are particularly interested in how Mtb gains access to the macrophage cytosol and the consequences of cytosolic access on innate immune outcomes. We are also working to understand how mitochondrial damage alters innate immune outcomes; in particular, we want to know why human mitochondrial mutations confer susceptibility to mycobacterial infection. We ask these questions via bacterial and mammalian genetics in macrophages ex vivo and in a mouse model of infection.

Ph.D.: Christian Tschudi, Ph.D., Yale University
Postdoc: Nevan Krogan, Ph.D. and Christine Guthrie Ph.D., UCSF
Interests: My lab studies post-transcriptional regulation of gene expression during the innate immune response in macrophages. We are broadly interested in how RNA binding proteins and components of the spliceosome are functionally specialized in response to pathogen sensing. We are currently working to understand how members of the SR and hnRNP families of splicing regulatory proteins control the maturation and stability of innate immune mRNAs. We also want to know how alternatively spliced protein isoforms perform distinct roles in innate immunity. Additionally, we seek to understand how intracellular bacterial pathogens like M. tuberculosis manipulate host gene expression by investigating secreted effector proteins that traffic to the macrophage nucleus.

POSTDOCTORAL FELLOW
Ph.D.: Brigette Huber, Ph.D., Tufts University
Interests: How does our immune system “know” when, or when not, to mount a proinflammatory response? I’m interested in gaining a better mechanistic understanding of the genetic and environmental factors involved in this question. To this end, my current work interrogates how mutations causing mitochondrial dysfunction dysregulate our immune system. I’m currently focusing on the role of LRRK2, a Parkinson’s disease associated kinase, on the innate immune system during M. tuberculosis infection.

Cory Mabry
GRADUATE STUDENT, MEDICAL SCIENCES
NIH/NIAID F31 Fellow
B.S. Texas A&M University
Interests: I am interested in host pathogen interactions and how pathogens exploit the host’s immune system to prolong infection. I am working to understand how Mycobacterium tuberculosis regulates the host immune pathways through manipulation of pathways associated with inflammatory responses.

B.S. Baylor University
Interests: I am interested in nuclear paraspeckles and the role they play in regulating the innate immune response in macrophages.
Lily Ellzey
GRADUATE STUDENT, TAMU Interdisciplinary Graduate Program in Genetics
B.S. Angelo State University
Interests: I am interested in how pathogens and innate immune pathways induce cell death within host cells and how those various forms of cell death ultimately impact the immune outcomes. In particular, lipid oxidation and pathways associated with the generation of mitochondrial ROS are of interest to me.
Morgan Chapman
GRADUATE STUDENT: MD/PhD program
B.S. Texas A&M University
Interests: I am interested in understanding the role RNA plays in coordinating the immune response, to minimize immunopathology and immunocompromisation. I am focused on two projects; the first, looks at on how alternative splicing by the splicing factor hnRNPA2B1 affects the mobilization of Type I and Type II interferon responses to Mycobacterium tuberculosis. The second, investigates the role of the nuclear RNA exosome in regulating nuclear and cytoplasmic type I interferon responses.

Interests: I am interested in cancer-associated mutations in splicing factors and how they impact innate immune gene expression.
Jacob (Jake) Davis
GRADUATE STUDENT, MD/PhD Program
B.S. University of Oklahoma, Medical Humanities Scholars BA-MD Program
Interests: I am interested in how interplay between infectious diseases and the immune system can determine disease outcomes. Specifically, I am interested in how Mycobacterium tuberculosis can manipulate innate immune pathways to evade host defenses and prolong infection. I am studying the role of LRRK2, a large multi-functional kinase with mutations implicated in Parkinson disease, inflammatory bowel disease, and susceptibility to mycobacterial infection, in regulating pathways of innate immunity.
