    Bio I have a background in the execution of molecular biology research as a former laboratory technician for 5 years during and following my undergraduate degree in molecular, cellular, and developmental biology. I also have a background in epidemiology and statistics through my MPH at UC Berkeley during which time I mastered the application of meta-analysis and systematic review techniques to infectious diseases topics, in particular in my masters thesis on HIV directly observed therapy. In addition, my years at Stanford as an internal medicine resident, infectious diseases fellow, and immunocompromised infectious diseases fellow have further developed my desire to address important translational questions that will improve the clinical outcomes of the patients that I care for on the stem cell transplant service. I hope to find therapies that might safely and effectively supplement and even take the place of antibiotics for prophylaxis and treatment of GVHD and infectious complications.

    Postdoctoral Research Fellow, Infectious Diseases

    Bio Arianna I. Celis Luna is a postdoctoral fellow in the lab of Dr. David Relman. Her research will investigate the role of the GI microbiome on iron absorption during pregnancy. She aims is to elucidate a functional role for the microbiome during this critical time period by combining metatranscriptomic and metametabolomic data from in vivo samples with biochemical data from in vitro samples. She hopes to shed light on how iron-deficiency anemia, still affecting ~50% of pregnant women in developed countries, can be more efficiently treated or prevented.

    Arianna received her Ph.D. in Biochemistry from Montana State University in 2018. She worked in the lab of Dr. Jennifer DuBois where her research focused on how, at the molecular level, bacteria build iron into the versatile molecule known as heme and break it apart again. Her work examined how these reactions are critical for both pathogenic species, such as Staphylococcus aureus, and the resident bacteria of the digestive tract.

    Arianna?s work encompasses 6 published papers in journals like the Journal of the American Chemical Society, the Journal of Biological Chemistry, and ACS Biochemistry. She has presented her work in several conferences, including Gordon Research Conferences and the ASBMB Annual Meeting, and at Montana State University as part of the Kopriva Science Seminar Series after receiving the Kopriva Graduate Student Fellowship.

    Postdoctoral Research Fellow, Infectious Diseases

    Bio Throughout my scientific training, I have focused on building an interdisciplinary background in molecular parasitology, biochemistry, immunology, and public health to provide me with the skills needed to pursue development of a successful malaria vaccine. My PhD research at Harvard centered on understanding immune responses to the developing transmission stages of malaria. By providing the first evidence for natural immunity to immature transmission stages, this work supports interrupting development and maturation of these parasites as a novel approach to transmission-blocking vaccine design. During my postdoctoral fellowship and in the future, I hope to continue researching host-pathogen interactions with applications to malaria vaccine development, while also being involved in global health work in the field. Currently my work focuses on understanding mechanisms of natural immunity to malaria and immune tolerance, particularly in the context of gamma delta T cell and monocyte responses.

    Current Research and Scholarly Interests Studying the host-microbiome relationship in very early-onset inflammatory bowel disease via microbial DNA sequencing and analysis. Evaluating expression of antimicrobial peptides and other immune mediators in human stool via mass spectrometry in collaboration with the Elisa lab on campus. Another project focuses on the gut and skin microbiome in children with severe acute malnutrition in Bangladesh (in collaboration with Gary Darmstadt).
