Seth Bloom

Seth Bloom

Postdoctoral Fellow - sbloom@mgh.harvard.edu

Seth joined the Kwon Lab in July 2016. He is an Infectious Diseases fellow in the combined Massachusetts General Hospital and Brigham & Women’s Hospital program. He earned a BA in Biology from Washington University in St. Louis, Missouri, in 2004, performing his undergraduate thesis work on influenza virus. Seth stayed at Washington University for his MD/PhD training and Internal Medicine residency, focusing his research on the role of commensal intestinal bacteria in a mouse model of inflammatory bowel disease. In the Kwon lab, his current work involves understanding interactions between bacterial microbiota and mucosal lymphocytes in the female genital tract, with a focus on how these interactions may influence risk of primary HIV infection. Outside of the lab, Seth enjoys running, hiking, spending time with family, and international travel.

Maud Deruaz

Maud Deruaz

Instructor in Immunology - mderuaz@mgh.harvard.edu

Maud is an Instructor in Immunology who joined the Kwon lab in October 2018. She obtained her Ph.D. in Biochemistry from the University of Geneva, Switzerland, during which she identified and characterized chemokine binding proteins from tick saliva. She then moved to Boston to pursue her interest in learning immunology from the perspective of pathogens. During her postdoc in the laboratory of Prof. Luster at MGH, she focused on the role of lymphocytes trafficking in HIV dissemination following intravaginal exposure in humanized mice. She is now poised to utilize this model to look at the role of microbiota in HIV intravaginal acquisition. Outside the lab, Maud enjoys spending time with her family, baking and embracing Boston’s cult of running.

Crystal Rawlings

Crystal Rawlings

Postdoctoral Fellow - crawlings@mgh.harvard.edu

Crystal is a postdoctoral fellow who joined the Kwon Lab in 2012 and received her Ph.D. in 2018 from the Harvard Biological & Biomedical Sciences program. Her thesis encompassed the investigation of HIV-1-associated alterations in the metabolism of vitamin A by human intestinal dendritic cells, as well as the effect of therapeutic retinoic acid supplementation on disease progression in HIV-1-infected individuals. She continues in the lab as a Research Fellow, moving her work toward publication and while maintaining her role as lab birthday celebration coordinator. Prior to moving to Boston, she worked as a technician and lab manager at the Benaroya Research Institute in her hometown of Seattle, WA. Crystal earned her BS in Biology and minor in Chemistry from the University of Washington while competing in Division I swimming. Outside of the lab, she now expends excess energy on her road bike with the Harvard University Cycling Association and maintains an open-access repository of gastronomic recommendations.

Upasana Das Adhikari

Upasana Das Adhikari

Postdoctoral Fellow - udasadhikari@mgh.harvard.edu

Upasana joined the Kwon Lab as a postdoctoral fellow in December 2018. Before moving to Boston, she was a Signgene Fellow doing her Ph.D. in a collaborative project between the Hebrew University of Jerusalem and Max Delbruck Centre of Molecular Medicine in Berlin. During her Ph.D., she studied the gut epithelial stem cell regeneration addressing the crosstalk between reserve and active stem cells. This led her to become fascinated by the three amigos of the gut: the epithelium, Gut Associated Lymphoid Tissue, and the microbiome. In the Kwon Lab, Upasana will study the cause of the misbalance of these interactions during HIV progression to halt the viral replication in the gut reservoir. In her free time, she loves to dance salsa and bachata!

Matt Hayward

Matt Hayward

Postdoctoral Fellow - mhayward2@mgh.harvard.edu

Matt proudly joined the Kwon lab as a Research Fellow in October 2017 to investigate the interplay between commensal microbes and tissues of the vagina in relation to HIV acquisition. From studying enteric pathogen, Salmonella enterica for his PhD, to elucidating the role of microbial communities in human health and disease for his first postdoc, Matt has maintained a focus on the microscopic. With extensive experience in both the wet-lab and dry-lab environments he has developed both pipetter’s shoulder and programmer’s slouch. In 2015, Matt was the lucky recipient of a Marie Curie Fellowship to pursue a project at EMBL Heidelberg with Prof Peer Bork on the relationship between the commensal microbes of the human gastrointestinal tract and colorectal cancer development. In his free time Matt can be found either pumping iron in the gym or with his nose stuck in a musty old book.

Muntsa Rocafort

Muntsa Rocafort

Postdoctoral Fellow - mrocafortjunca@mgh.harvard.edu

Muntsa joined the Kwon Lab as a postdoctoral fellow in February 2019. She finished her Ph.D. in Microbiology at Universitat Autonoma de Barcelona in 2018 working on the gut microbiome and HIV-1 infection at the AIDS Research Institute IrsiCaixa in Barcelona (Catalonia). Before that, she did an MsC in AIDS Treatment and Pathogenesis and an MsC in Bioinformatics. After spending almost all of her Ph.D. sitting in front of the computer, Muntsa joined the Kwon Lab ready to focus on wet lab work. Her aim is to decipher the role of phages on the changes occurring in the gut microbiome during HIV-1 infection. In her free time, she loves drawing, reading thrillers and cuddling around with her 2 cats.
