HHMI recognizes early-career scholars

Josefina del Mármol

del Mármol is an assistant professor of biological chemistry and molecular pharmacology at Harvard Medical School. The del Mármol lab uses structural biology, electrophysiology and neurogenetics to understand how olfactory receptors translate the chemical complexity of the environment into interpretable neuronal signals that enable robust odor-driven behavior. She received a National Institutes of Health MOSAIC K99/R00 Pathway to Independence award, the Polak Young Investigator Award by the Association for Chemoreception Sciences and the Blavatnik Regional Award in Life Sciences. She was recently named a Pew Biomedical Scholar.

Elizabeth Johnson

Johnson is an assistant professor of molecular nutrition at Cornell University. Her lab focuses on how specific nutrients promote the development of the infant gut microbiome and impact infant health. Johnson’s work will better inform caregivers about nutritious food for their babies to support lifelong, microbiome-dependent health. In 2022, Johnson was named a Pew Biomedical Scholar, and she was named a NIH National Institute of General Medical Sciences Judith H. Greenberg Early-Career Investigator Lecturer and a CIFAR Azrieli Gobal Scholar in the Humans & Microbiome Program in 2021.

Juan Mendoza

Mendoza is an assistant professor of molecular engineering at the University of Chicago, Pritzker School of Molecular engineering. His lab studies cytokine-related interactions outside and inside of cells and aims to find new ways to improve immunotherapies by using small molecules or engineered proteins. As a postdoctoral scholar, he was awarded an NIH National Cancer Institute Career Development Award and fellowships from the Helen Hay Whitney Foundation and the Damon Runyon Cancer Research Foundation. In 2019, the International Cytokine and Interferon Society gave him the Milstein Young Investigator Award for his contributions to the field. In 2022, he was elected to the ASBMB Nominating Committee.

Judith Simcox

Simcox is an assistant professor of biochemistry at the University of Wisconsin–Madison. The Simcox lab works to identify novel lipids in the circulation, determine how their production is regulated and discover how these plasma lipids function in metabolic disease. In 2017, she was awarded the American Heart Association Postdoctoral Fellowship for her work on circulating lipids as a fuel source for the heart during cold exposure. More recently, she was named an Emerging Investigator by the University of Illinois Chicago in 2020. The ASBMB recently announced that she will receive the 2024 Walter A. Shaw Young Investigator Award in Lipid Research.
