Indian software firm Infosys continues to suffer the departure of its top-level executives as senior vice president S Goparaju Goparaju is all set to leave the firm.

Goparaju, senior vice-president & head of Infosys Labs, quit the firm after rendering 25 years of service to the second largest software firm of the country.

It may be noted here that Infosys Labs is the research & development (R&D) division of the company. Goparaju also headed the company's intellectual property cell. Most recently, he was inducted into the firm's executive council.

Infosys declined to offer a reason for Goparaju's exit, except saying that the executive's last day at the firm would be December 27.

A spokesperson for the firm said, "We would like to thank Subu for his contribution and leadership, especially in building Infosys Labs. Savio D'Souza, will manage Infosys Labs's Service Differentiation Platforms group, and Dr Anindya Sircar will manage the IP cell."

Both, D'Souza and Sircar will report to Chandrashekar Kakal, the global head of business IT services at the firm.

Goparaju's departure comes just a month after the departure of Stephen Pratt, head of utilities & resources for the firm's North America business. It also marks the seventh major exit from the executive council in just six months.
