We warmly welcome you to e-Science 2007, the 3rd IEEE International Conference on e-Science and Grid Computing sponsored by the IEEE Computer Society’s Technical Committee for Scalable Computing. This year event hosted by the Centre for Development of Advanced Computing (C-DAC) building on the success of previous two meetings:e-Science 2005 in Melbourne, Australia and e-Science 2006 in Amsterdam, The Netherlands. The organisation of e-Science 2007 in Bangalore has been championed by Srinivasan Ramakrishnan, Director General of C-DAC on behalf of the Indian IT and Supercomputing community. Bangalore with its booming growth in information technology, telecommunication, and bioinformatics, housing several premier research institutions in science and technology is truly the science hub of the country. Soaked in the rich tradition of Karnataka, Bengaluru offers something for everyone-music and dance concerts (Western and Indian), dramas, exhibitions, carnivals, conferences and more. It is our pleasure to welcome you to Bangalore!

e-Science 2007 is an important conference for the international e-Science community as it provides a forum for all e-Science and Grid researchers, developers and users and those who are just curious to see the project results and become aware of the progress made in this area.

The conference program comprises of keynote talks, peer-reviewed research papers, workshops, an industry track, tutorials, and a poster and research demo session.

We are extremely fortunate to have three distinguished Keynote speakers representing North America, Europe, and Asia: Professor Mark Ellisman of The National Center for Microscopy and Imaging Research (NCMIR) at the University of California San Diego in the USA, Professor Thomas Fahringer from the Institute of Computer Science at the University of Innsbruck in Austria, and Professor Xiaoming Li from the School of Electronic Engineering and Computer Science at Peking University in China.

The selection of top quality papers from large submissions requires extra effort and commitment to ensure that a high standard of refereeing is enforced consistent with truly international conferences. As a result special thanks are due to the Steering Committee, the Program Committee (chaired by Geoffrey Fox and the large team of program committee members who handled the refereeing of the submitted papers). The program committee Chair and Vice Chair (Kenneth Chiu) have coordinated peer-reviews of all submitted papers and selected 60 top quality research papers out of 206 submissions from all over the world for presentation at the conference.

We would like to extend our appreciation to our colleagues who have supported and guided the conference towards success. At the outset, we would like to thank our honorary chairs N. Balakrishnan, A.K.Charavarti and S.Ramakrishnan for their support and encouragement. We thank Dick van Albada for coordinating the organisation of 4 satellite workshops. We appreciate the efforts of the chairs of various workshops and their PC members for attracting and selecting top quality papers for presentation at the conference. We thank Dan Katz for organising and managing the poster and research demo session along with Prahalad Rao, Sathish Vadhiyar and Mark Baker for soliciting and selecting high quality tutorials from international researchers, Madhusudana Rao for the excellent management of the conference website, and publicity coordinators (led by Heinz Stockinger) for helping us reach a broader community. We thank Thomas Baldwin and Patrick Kellenberger for their support in ensuring the publication of the conference proceedings in record time.

As we all know, the local arrangements are a key aspect of any event. We thank Bindhu Madhava and Rao Aiyagiri for serving as organising chairs and managing all local aspects along with the organizing committee members. Efforts of K. Kalyansundaram in managing conference finances are highly appreciated. Special thanks to S.Sadagopan for coordinating industrial sponsorship, Radha Nandhkumar, Cho-Li Wang and V. Sundarajan for conference publicity, Subrata Chattopodhyay and Prabu Kumar for conference registration and M.R.Rajagopalan for organizing the industry track.

Ultimately, however, the success of the conference will be judged by how well the delegates have participated, learnt, interacted and established contacts with other researchers in different fields. The committees and the sponsors have provided the funding, the venue and the environment to allow these objectives to be achieved. It is now up to all of us to ensure that the conference is an outstanding success.

Finally, we wish everyone a successful, stimulating and rewarding meeting and look forward to seeing you again at future e-Science conferences including e-Science 2008 in Beijing.

Enjoy your visit to software city Bangalore and incredible India!
