PRINCIPAL INVESTIGATOR

B.A. Wesleyan University, Molecular Biology & Biochemistry, Physics

Ph.D. Johns Hopkins University School of Medicine, Molecular Biophysics

Alison Ringel is a T cell immunologist who seeks to decode how immune cells adapt to stress in healthy and diseased states. Alison graduated from Wesleyan University with degrees in Molecular Biology & Biochemistry (MB&B) and Physics. She joined the Program in Molecular Biophysics at the Johns Hopkins University School of Medicine for her doctoral research, where she worked under the mentorship of Dr. Cynthia Wolberger in the Department of Biophysics and Biophysical Chemistry. There, she studied molecular mechanisms that regulate the activity and specificity of chromatin-modifying enzymes using biochemical and structural approaches. For her postdoctoral studies, she joined the laboratory of Dr. Marcia Haigis in the Cell Biology Department at Harvard Medical School to study how metabolic stress impacts anti-tumor immune responses. She started as an Assistant Professor in the MIT Biology Department and Core Member at the Ragon Institute in January 2022. When she’s not at the Ragon Institute, Alison loves exploring the outdoors with her family and taking her dog for long walks around Jamaica Plain.

  • Claire McIntyre, PhD

    POSTDOCTORAL FELLOW

    B.Sc. University of Strathclyde, Immunology and Pharmacology

    M.Res. University of Glasgow, Biomedical Sciences

    Ph.D. University of Glasgow, Immunology

    Claire is an immunologist who is interested in how metabolism shapes the immune response in the context of cancer. Claire began her scientific career in Scotland (UK), first completing undergraduate studies in Immunology and Pharmacology at the University of Strathclyde, followed by a Masters in Biomedical Sciences at the University of Glasgow. Claire continued her studies at the University of Glasgow, starting her PhD in 2015, under the mentorship of Dr. Vicky Morrison. Here, she first gained an interest in unconventional γδ T cells, studying the role of beta2 integrin receptors in regulating γδ T cell responses. Claire then moved to Boston in 2019 for her postdoctoral studies, joining the lab of Professor Lydia Lynch at Brigham and Women’s Hospital/Harvard. Here, she began uncovering the metabolic pathways that regulate the functions of both pro- and anti-tumor γδ T cells, with the aim to identify new ways to target γδ T cells for cancer therapy. In 2024, Claire joined the Ringel lab to continue this work in collaboration with the Lynch lab. Outside of work, Claire enjoys baking and taking bike rides to explore the many parks around Boston with her family.

  • David Ye

    David Ye

    GRADUATE STUDENT, MIT BIOLOGY

    B.A. Swarthmore College, Biochemistry

    David is a Ph.D. student co-mentored by Dr. Alison Ringel and Dr. Bruce Walker. He is broadly interested in how metabolism affects the interplay between HIV and T cells. Specifically, he is intrigued by questions such as how different metabolic environments impact T cells’ ability to combat HIV infection, and what cellular and tissue environments that allow some patients to be able to spontaneously control HIV replication in absence of anti-retroviral therapy. Born and raised in Beijing, China, David travelled to Swarthmore College and earned his B.A. in Biochemistry with a minor in Gender and Sexuality Studies. During his undergraduate study, he worked in Dr. Liliya Yatsunyk’s lab, where he solved X-ray crystal structures of a form of non-canonical DNA structure named G-quadruplex and investigated their interactions with small-molecule ligands. His structural work aimed to understand the structural diversities G-quadruplexes to better develop therapeutics targeting them. In his free time, David enjoys rock climbing, exploring new restaurants and boba places with friends, and playing video games.

    Erika is a Technician in the Walker and Ringel labs at the Ragon Institute, where she works alongside Josh to explore the role of cellular metabolism on HIV infection and control. She went to Kenyon College for her undergraduate studies, where she majored in Molecular Biology and obtained a B.A. degree in 2023. Early in college, Erika joined Dr. Sarah Petersen’s lab, where she studied muscle pre-patterning requirements for proper peripheral nervous system development. She also briefly worked as a Summer Research Scholar in Dr. Robb Krumlauf’s lab at the Stowers Institute for Medical Research, where she researched the coupling of retinoic acid signaling and hindbrain segmentation in lamprey. Erika hopes to continue exploring her interests in biology and going to graduate school in the next two years. Outside of the lab, Erika enjoys playing sports, hiking, rock climbing, playing the piano, and cuddling with her cat, Momo.

  • Josh Acklin, PhD

    POSTDOCTORAL FELLOW

    B.S. University of Rochester, Microbiology and Immunology

    Ph.D. Icahn School of Medicine at Mount Sinai, Biomedical Sciences

    Josh is a viral immunologist who is interested in fundamental questions of how viruses shape immune responses, and how immune responses subsequently shape disease. Josh completed his undergraduate training at the University of Rochester in 2017, where he majored in Microbiology and Immunology. He then went on to receive a PhD in Biomedical Sciences from the Icahn School of Medicine at Mount Sinai in July of 2022 under the mentorship of Dr. Jean K. Lim. There, he focused on identifying ways in which viruses exploit the host immune response to enhance infection and pathogenesis. Josh is currently transitioning into a joint appointment between the Ringel and Walker labs at the Ragon Institute for his postdoctoral training. Here, Josh will work on two major projects: 1) He aims to better understand how cellular metabolism influences CD8 T-cell responses to HIV; and 2) He will focus on elucidating the relationship between lipid utilization and HIV-infection. Collectively, his work aims to better understand why some patients with HIV are capable of spontaneously controlling infection in the absence of therapy with the goal of identifying novel therapeutic targets. Coming from the concrete jungle, Josh spends his time outside of the lab biking around the greater Boston area, exploring nature in the Northeast. He also has an interest in the classics, and frequents museums and exhibits on ancient Greek architecture, culture, and art. Finally, Josh is very passionate about the role of science in public policy. He co-chaired March for Science NYC during his time in NY and plans to resume his science policy work in MA once he’s established himself in the lab here at Ragon.
