Mae Rhodri yn Athro mewn Cryfder a Chyflyru Pediatreg ac yn Gadeirydd y Ganolfan Datblygiad Corfforol Ieuenctid ym Mhrifysgol Metropolitan Caerdydd. Mae ganddo hefyd swydd cyswllt ymchwil gyda Phrifysgol Technoleg Auckland ac mae'n gymrawd ymchwil i Sefydliad Technoleg Waikato. Mae ei ddiddordebau ymchwil yn ymwneud ag effaith twf ac aeddfedu ar ddatblygiad athletau tymor hir a'r mecanweithiau niwrogyhyrol sy'n sail i addasiadau hyfforddiant mewn ieuenctid. Mae'n uwch olygydd cyswllt ar gyfer y Journal of Strength and Conditioning Research ac fel golygydd cyswllt ar gyfer y Strength and Conditioning Journal. Yn 2016, derbyniodd wobr Hyfforddwr Cryfder a Chyflyru'r Flwyddyn am Ymchwil ac Addysg gan Gymdeithas Cryfder a Chyflyru'r Deyrnas Unedig (UKSCA) ac yn 2017 dyfarnwyd iddo wobr Ymchwilydd Ifanc Eithriadol y Flwyddyn Terry J. Housh gan y Cryfder Cenedlaethol. a Chymdeithasu Cyflyru (NSCA). Ef yw Cadeirydd presennol Grŵp Diddordeb Arbennig Datblygu Athletau Hirdymor yr NSCA, a rhwng 2011-2015 bu'n Gyfarwyddwr Bwrdd ar gyfer UKSCA.
