Here's the short abstract of the article in SciDev.net: "India should be inspiring science and technology graduates to stay in the sector, rather than building new institutions."
In a study he conducted at IIT-Madras (where he surveyed both faculty and students), Kamath explored the factors behind S&T graduates' career choices. Here's his rather bleak summary of 'economic, non-economic and institutional' reasons behind why students leave S&T careers:
To begin with, students report being de-motivated by uninspiring classroom environments. They criticise textbooks as being sluggish and out of touch with reality.
Many students report that internships, which are supposed to give them hands-on experience of industry, only fuelled further disinterest or indifference towards an S&T career. Many claim they faced a bureaucratic work environment and outmoded infrastructure in the S&T organisations they are sent to, which stonewalls their creativity.
Even seemingly minor factors, like the quality of pre-placement presentations, sway students' minds. Students observe that wealthier multinationals, even many homegrown corporations, are conscious of the attractive power of good presentations and have visibly invested in them, in contrast to presentations by many government-run R&D labs or even private S&T organisations.
And however much teachers strive to make S&T or R&D more appealing and relevant, the long time it takes to gain recognition in a research career leave students uninspired. In today's highly connected and informed world, finding alternative professions or academic opportunities that offer faster recognition — in India or beyond — is easy.
There's also a somewhat more extended summary of Kamath's work.
