Sreedher's work on science popularisation (including space technology) through radio was when I first met him, over three decades ago. His outstanding work in science and education in AIR was taken further when he joined IGNOU, and worked on Gyan Darshan and Gyan Vani. Here, and later in CEMCA (an offshoot of COL), he used and further honed his capabilities in educational communication. His pioneering efforts in community radio resulted in India's first such station in Chennai, and let on to some exemplary projects.
