nni, the collaboration would want to see the nni working groups identified this data gap and it goes to understanding the exposure from consumer products that have nano materials in them. and so there's plenty, there's a billion dollars, more than a billion -- billions that has been spent by the federal government on advancing nano technology, but none of that or very little of that money has gone to understanding the specifics of consumer product exposure, which is unique exposure. if you have a child out swinging a tennis racket and every time the child hits a ball, nano particles fly off and the child is breathing those in and those particles mirror asbestos, these are critical health and safety requests that we want to get at and are in the requests. >> you listed four categories as criteria for success. first is to develop robust test methods to determine and characterize human exposure to nano materials. what defines a robust testing method? >> that's what i leave to toxicologists. that's what this working group has been working on with money congress has been giving us and tha

>> through the nni working groups there's a good amount of interaction. our staff reports back. >> does nni mean other agencies work on nano with yourselves or that's pretty much the primary agency? what other agencies? >> department of defense, homeland security. there are many, many agencies as part of nni. >> okay. that's my questions. yield back by saying go rockets. >> the chair thanks the gentleman. the gentleman yields back. the chair recognizes mr. guthrie from kentucky, five minutes for your questions, please. >> thank you, mr. chairman. i was preparing for the hearing today, i talked about commissioner buerkle, showed up, it is you. glad to have you back. i didn't realize that you were in this role and always really enjoyed serving with you as mr. pompeo and i spent time in the state of new york, always fun to talk about you about what was going on with you back there. i have a question. on table saws. back when we were serving together table saw manufacturers in my district and i understand that the cpsc has begun a special study of national el

from the federal government for all agencies to work together commonly nni working groups and identify the data gap and it goes to understanding the exposure from consumer products that nano materials in them. and every time the child hits the ball come in the nanoparticles fire off in the near expresses. >> the robust message to characterize materials. what defines a robust testing method? >> that is what i leave to our toxicology spirit this is what we've been working on in conjunction with the national science foundation as well as manufacturers and agencies to help get the style. i can't decide what reaches that threshold but i think we've got the technical expertise that our staff level to make the determination. >> in your letter you expect to establish the research center with 12 senior scientist on the 15 technicians 10 postdoctoral students and 12 graduate students. these come from the current staff or outside? >> they would come from outside is part of the funding. >> how much expertise is the current staff have on these issues? they've been working since 2011. >> we have a t
