    Our lab seeks to dissect the interplay between redox processes and age-dependent changes in tissue function in the nematode C. elegans, in order to shed light on the association between the dysregulation of the cellular redox environment and many human diseases of aging.

     

    Our research focuses on redox processes that span increasing levels of organismic structure—from the molecular to the cellular and organismic levels. We study how oxidation affects the function of proteins and signaling pathways at the molecular level, using molecular biology and CRISPR-Cas9 genome editing. We probe how protein oxidation is regulated at the cellular and tissue levels, using genetically-encoded protein oxidation sensors that we monitor via ratiometric fluorescence microscopy in live animals. We use system-biological tools to integrate how redox control affects organismic traits, including lifespan.

     

  • Opportunities

    We are recruiting curious, enthusiastic and hard working budding scientists to join our team!

    Graduate students

    Graduate students from Biology, Bioengineering, and other graduate programs at Northeastern University are eligible to join the lab. We have several rotation projects available, which can be tailored to the specific interests of the student. Please contact Javier if you are interested.

    Undergraduate students

    Undergraduates interested in using molecular-genetic approaches to study the mechanisms that regulate lifespan in the nematode C. elegans should contact Javier to discuss possible projects. Please submit your CV, transcript and a brief paragraph detailing why you want to work in our lab.

    Postdoctoral fellows

    We are looking for candidates interested in combining experimental and theoretical approaches to study the regulation of protein oxidation at molecular and cellular levels. Please send Javier your CV, a copy of a first-author manuscript or draft, and a cover letter describing your research experience and future goals.

    Laboratory technician

    We are looking for a new lab manager and technician, since Will Heath moved back to the west coast, after three years in our lab. Please see the job description and apply via the Northeastern portal.

    We are super excited that our CAREER proposal "Intercellular regulation of protein oxidation during aging" was funded by the National Science Foundation's Division Of Integrative Organismal Systems! To learn more about this project, please read's Tim Briggs interview with Javier.
    We published a book chapter in Methods in Molecular Biology with Prof. Scott Alper where we argue that worms are an excellent organism to model human diseases.    Here is the abstract: Numerous approaches have been taken in the hunt for human disease genes. The identification of such genes not...
    Congratulations to our undergraduate student Sean Johnsen, who received this award! The Matz Co-op Program, generously funded by NU alumnus Robert Matz and his wife Eileen, supports NU undergraduates in six-month research co-ops in the labs of NU faculty who work in the area of biotechnology....
    We just published our first preprint in bioRxiv: Age-dependence and aging-dependence: The case of neuronal loss and lifespan in a C. elegans model of Parkinson's disease. By Javier Apfeld and Walter Fontana. The main point of this work is to call attention to untested assumptions regarding the...
    We are so happy that Alex has found a permanent home in the Vascular Biology Program at Boston Childrens Hosptial. He will be working under the direction of Drs. Robert D'Amato and Mehrdad Khajavi, using zebrafish to study angiogenesis.
    Congratulations to our undergraduate students Hannah Tam, Julian Stanley, Sarah Brennan and Stephanie Stumbur, each of whom received one of these awards! Honors Early Research Assistantships offer undergraduate Honors students the opportunity to work as research/lab/production/studio assistants...
    We are so happy to move to our fully renovated new lab space! It is right next door to our temporary space.
