Research Associate or Postdoctoral Fellow at Tufts University, Graduate Sciences and Medical School Campus, Boston
Overview: A high proportion of the elderly suffer from age-related loss of vision. We elucidate relationships between environmental stress, physiologic stress responses, protein quality control and eye function in order to discover mechanisms of aging, and nutritional and other means to delay age-related vision impairments such as age-related macular degeneration and cataracts. Projects are mature and much data is already available. Tufts Medical Center is a highly collaborative and productive environment in downtown Boston, within ~20 minutes from Harvard, MIT, Boston Univ. The lab is funded by NIH, USDA, several foundations.
Position Description: We seek outstanding candidates with a recent PhD in Biochemistry or a related discipline to work on one of the following funded projects:
1) Discovering novel stress-induced ubiquitin and autophagy enzyme interactions in response to glycative stress.
2) Regulatory mechanisms of eye lens differentiation,
3) Elucidate interactions between dietary glycemia, metabolomics, microbiome, AMD, cataract, and aging in animal studies and/or human populations, including planning randomized intervention studies.
The following are important: training in biochemistry or a related discipline, bioinformatics, histology, analyzing large data sets, animal husbandry. Candidates should have at least two English language first authored papers and 1 year of experience. A 2 year commitment is required. Preference will be given to candidates who have permits to reside in the USA. All candidates must have or obtain a suitable visa.
