Principal Investigator

Kate Jeffrey   |

Dr. Kate L. Jeffrey is an Assistant Professor of Medicine at Harvard Medical School, an Assistant in Immunology at Massachusetts General Hospital, Faculty of Harvard Immunology and an associated researcher at the Broad Institute of MIT & Harvard. Kate grew up in Australia, performed her undergraduate studies (B.Sc (Honors)) at the University of Melbourne, Australia, and completed her Ph.D. in immunology with Professor Charles Mackay at the Garvan Institute of Medical Research in Sydney, Australia. She then worked as an Immunology editor with Nature Medicine in New York in 2007 before performing her postdoctoral research with Professor Sasha Tarakhovsky at The Rockefeller University in New York focusing on epigenomic regulation of innate immunity and inflammation. Kate is also co-founder of the New York Imagine Science Film Festival in New York City. She started her independent laboratory at MGH/Harvard in the summer of 2012.

Postdoctoral Fellows

Hajera Amatullah   |

Hajera joined the lab in October 2016 as a post doctorate fellow. Hajera did her Bachelor of Science in Biochemistry and Environmental Sciences at the University of Toronto, Canada followed by a Master of Public Health at the University of Toronto. Her masters work with Dr. Jeremy A. Scott looked at the mechanisms underlying air pollution-induced cardiorespiratory dysfunction in naïve and asthmatic murine models. She then completed her PhD in Physiology at University of Toronto under the supervision of Dr. Claudia dos Santos and her work revolved around investigating novel therapeutic targets in sepsis-induced multi organ failure.

Fatemeh Adiliaghdam   |

Fatemeh joined the lab in August 2016 as a post doctoral fellow. Fatemeh obtain her MD from Tehran university of Medical Sciences in Tehran, Iran followed by a Master of Public Health at the same university. She then moved to the US and did her first post doc in the Laboratory of Gastrointerstinal Epithelial Biology in MGH under the supervision of Dr Richard Hodin. Here she examined burn induced gut hyperpermeability in mouse models and how intestinal alkaline phosphatase (IAP) helps to improve gut barrier function in this context. In parallel, she examined how IAP as a regulator of gut barrier and anti-inflammatory enzyme could extend life span in Drosophila and C.Elegans in an aging model. In the Jeffrey lab, she is examining host antiviral responses to both pathogenic and symbiotic viruses. Fatemeh hopes to eventually complete her surgical residency in the US and be a physician scientist.

Outside of lab interests: Basketball, movie nights, dancing


Graduate Students

Hembly Rivas   |

Hembly is from Saugus, MA. She graduated from the University of Massachusetts, Boston in 2014 with a BS in Biology. Afterwards, she spent two years working in the laboratory of Dr. Marta Gaglia at Tufts School of Medicine studying viral host interactions of Kaposi’s Sarcoma-associated herpesvirus, specifically identifying viral factors that regulate host gene expression during infection. She started pursuing her PhD in the Department of Virology at Harvard School of Medicine in fall 2016 and joined the Jeffrey Lab in summer 2017. She is interested in understanding how resident viruses in the gut contribute to immune homeostasis and disease. If she’s not in lab, Hembly is likely reading, discovering new places to eat, or traveling.
