Beathaisnéis: Rugadh agus tógadh Ruairí de Fréin i mBaile Átha Cliath.
Ghnóthaigh Ruairí na céimeanna B.E. san Innealtóireacht Leictreach agus Dioplóma Iarchéime “Licentiate of the Royal Schools of Music” (LRSM) sa Cheol ó Ollscoil na hÉireann, Baile Átha Cliath, agus ón mBord Comhlachaithe na Scoileanna Ríoga Ceoil (The Associated Board of the Royal Schools of Music) i 2004 agus 2012.
Tá céim dochtúireachta bainte amach aige i “Signal Processing” leis an teideal “Adapting Bases Using the Synchronized Short Time Fourier Transform and Non-Negative Matrix Factorization” faoi stiúir an t-Ollamh Scott T. Rickard (matamaticeoir).
Chaith sé tréimhse i mbun taighde agus ag stiúradh mic léinn dochtúireachta agus máistreachta in Institiúid Teicneolaíochta Phort Láirge (WIT). Ghnóthaigh Ruairí deontas taighde ó Fondúireacht Eolaíochta Éireann (Science Foundation Ireland) chun taisteal go dtí Universidade Federal do Paraná i Brazil. I 2014 chaith sé tréimhse mar “Eolaí ar Chuairt” Marie Skłodowska-Curie, le Amadeus SAS i Nice sa Fhrainc. Tá sé ina Chomhalta Taighde Marie Skłodowska-Curie d’ollscoil KTH Royal Institute of Technology sa tSualainn anois.
Tá moll mór de pháipéir léannta foilsithe ar a thaighde innealtóireachta i mBéarla go nuige seo. Tá sé mar bhall de Chumann na nInnealtóirí agus de roinnt Institiúidí eile.
Is amhránaí traidisiúnta agus clasaiceach é Ruairí agus is ball é den ghrúpa amhránaíochta traidisiúnta iomráiteach “Concordia”. Bhí sé páirteach i riar mhaith dlúthdhioscaí mar amhránaí agus mar thionlacaí chomh maith le bheith gníomhach i gceolchoirmeacha san Eoraip agus níos faide i gcéin, mar shampla leis an ngrúpa 'the Keynotes', i “Will Ye Go To Flanders?” le Concordia i “Passetyme with Goode Companye” agus ceoldráma “The Invader” le Eric Sweeney.

Biography
Ruairí de Fréin received a Bachelors degree in Electronic Engineering from University College Dublin, Ireland, in 2004. He received his Ph.D., which he completed with the Sparse Signal Processing Group in the Complex and Adaptive Systems Laboratory in University College Dublin, Ireland, in 2010, under the supervision of Dr. Scott Rickard. His research interests include Sparse Signal Processing, Blind Source Separation, Non-negative Matrix Factorization and Time-Frequency Analysis.
He is currently a postdoctoral researcher in the Telecommunications and Software Systems Group in Waterford Institute of Technology and is funded by Science Foundation Ireland as part of the FAME ("Federated, Autonomic Management of End-to-end communications services") strategic research cluster and by a Technology Innovation Development Award.
In the past few years he has developed algorithms for Network Management and Self-Organization strategies for small cell networks, and monitoring techniques for Internet Protocol TeleVision (IPTV) in collaboration with IBM Tivoli and Alcatel Lucent.
Dr. de Fréin for the past several years has focused on Scalable Distributed Network Monitoring Methods, Formal Concept Analysis, Independent Component Analysis, Machine Learning and the application of Time-Frequency methods and sparse Signal Processing for the Blind Separation and Localization of more sources than sensors.
