When it comes to computer science education in developing countries, the gap between the best education and the average is large. The gap between knowledge provided and required to reach current research level is even larger. To bridge this gap and expose professionals to the best minds in the computing business, TCS has organised 'TCS Excellence in Computer Science Week (TECS)'. TECS is the third in the series being organised at the TRDDC (the R&D arm of TCS) in Pune from January 4 to January 8, 2005. This year's theme is security modelling and the company has brought under one roof the biggest names in this area, said Sachin P Lodha, scientist, TRDDC. Amir Pnueli, professor for computer science at the New York University and winner of ACM Turing Award for his seminal work introducing temporallogic into computing science and programme and system verification was the main speaker. Prof Butler Lampson from Microsoft Research, Cambridge US, Prof John Mitchell from Stanford University, USA, Prof Xavier Leroy from INRIA France and Prof Josyula R Rao from IBM Research, T J Watson Centre, USA are the experts who are talking on security modeling. They are providing participants an overview of the latest techniques of computation security. Participating to the even is strictly by invitation and there are only 75 seats on offer. This time, TCS got 25 applications from overseas to participate at the week-long programme that exposed participants to cutting edge research. The TECS Week is organized by TCS. For participants from developing countries, funding is provided by the International Institute for Software Technology.
