Javier Apfeld

Roles & Affiliations: Javier Apfeld is an Affiliated Faculty member in Bioengineering and an Assistant Professor in the Department of Biology at Northeastern University. His lab focuses on understanding how the brain regulates aging and stress resilience in C. elegans, leveraging interdisciplinary approaches combining molecular genetics, microscopy, and engineering.

Education: PhD in Biochemistry from University of California, San Francisco (1999); BSc in Biology from MIT (1994).

Research: Key areas include protein oxidation dynamics, microbiome interactions, and lifespan regulation. Technologies used include biophysically-calibrated microscopy and automated lifespan analysis systems. Current projects explore intercellular protein oxidation regulation and microbiome-modulated resilience.

Publications: Over 20 peer-reviewed articles, including work on sensory decision-making in C. elegans and the SensorOverlord biosensor analysis tool. Recent high-impact studies focus on temperature-dependent stress defenses and lifespan scaling mechanisms.

Awards: NSF CAREER Award (2020), HHMI Predoctoral Fellowship (2015). Lab develops interdisciplinary tools for quantitative biology and trains students across biology, engineering, and data science.

Lab Activities: Recruiting undergrads, grad students, and postdocs. Current lab members include over 30 trainees. Alumni have transitioned to roles in academia, biotech, and medicine.
