Gyda'r cadeiriau ymchwil hyn daw Rhwydweithiau Ymchwil Cenedlaethol. Rydym wedi sefydlu tri, un ym mhob un o'r meysydd 'her fawr' a nodwyd yn Gwyddoniaeth i Gymru. Mae staff Llywodraeth Cymru, mewn cydweithrediad â'r prifysgolion ymchwil-ddwys ar draws Cymru, wedi cytuno ar ffurf a chwmpas y Rhwydweithiau hyn. Mae'r trefniadau ar waith ar gyfer eu lansio'n ffurfiol - ym Mhrifysgol Bangor ganol fis Mawrth.
Along with these research chairs, come three National Research Networks. We have established one in each of the ‘grand challenge’ areas identified in Science for Wales. Welsh Government staff, working with the research-intensive universities across Wales have agreed the form and coverage of these Networks. Arrangements are in hand for a formal launch for these  - at Bangor University, in the middle of March.
