I came to know Prof. G. Rajasekaran through Sunday classes only. I learned many things from him. It helped me to qualified NET and GATE. Once, I faced difficulty in my Ph. D, and Prof. Rajasekaran tried to help me. That time I realized how much he cared for students. I am grateful to him. Unfortunately, his dream project INO did not complete in his lifetime. My deepest condolence to his family, friends and colleagues.
