When discussing the Navyâs top science and technology (S&T) priorities with military, government and industry leaders, Chief of Naval Research Rear Adm. Mat Winter reflected on his college days at the University of Notre Dame. âWhen I graduated from Notre Dame 30 years ago, many of the things that the Navy had in the âpetri dishâ back then, so to speak, are being used today throughout the fleet,â said Winter. On Jan. 13, Winter gave the keynote address at the Surface Navy Associationâs 28th Annual Symposium, held in Crystal City, Virginia.
