Participation of academic scientists in relationships with industry.

Relationships between academic researchers and industry have received considerable attention in the past twenty years. However, current data on the prevalence, magnitude, and trends in such relationships are rare. In a mailed survey of 3,080 academic life science researchers conducted in 2007, we found that 52.8 percent have some form of relationship with industry. Life science faculty with industry research support were more productive than faculty without such support on virtually every measure. However, we also found a significant decrease in industry support of university research, which could have major consequences for the academic life science research sector.
