I am a PhD student studying in the US and I am interested in finding research-grants relevant to the research area to which I have recently switched to, viz. computational geometry problems in robotics.
As of now, I don't want to apply for a grant, but I want to get an overview for what kinds of problems do public and private research grants get offered to researchers in my field.
While googling I stumbled upon grants.gov on which different government agencies post funding opportunities relevant to their interests, and that this database is searchable by keyword.
The NSF website is also very useful. However their grant solicitations like this one seem quite open-ended and are not more specific on what kinds of problems need to be solved, (but please correct me if I am wrong, I am still exploring this website! :-D )
Are there similar "messaging-boards" where private companies, interested in funding university research for a relevant problem post their funding opportunities? If not, how do you efficiently find such grants ?
I am interested in this because I feel private companies will be more specific on what kinds of problems they encounter and would like to be solved.
