Data hub for environmental exposures

Question

[Lorenzo Fabbri]

I graduated a few months ago and I am now looking for PhD positions. I would like to improve my CV and learn new skills: since I will hopefully work on environmental health, I would like to work on a relatively small personal project linking GIS data and -omics data. I used GEO datasets before, but I never looked at the exposure (pollution, diet, etc...), and I am now facing some issues retrieving the needed data. Are you aware of any data hub where you can search for datasets based on the exposure? It would be nice if you can also filter data based on the geographical location (PM measured in, e.g. Seattle).
