Twitter Inc's vice president for corporate development and strategy, Rishi Garg, has resigned. Garg's resignation is the latest in a recent string of departures from the company including that of CEO Dick Costolo.

Garg, whose role put him in charge of the mergers and acquisition strategy, announced his departure after a tenure of 13 months.

"After an amazing ride as Twitter's VP Corporate Development and Strategy, I'm saying farewell today," he tweeted Friday.

"Our team has built a stronger Twitter with a dozen acquisitions in the last year. Hats off to @dickc for admirable leadership, humour, energy, and trust," Garg tweeted.

"I can't wait to witness the company's next chapter. I'm off to pursue some exciting new projects; more soon! #staytuned," the tweets read.

Twitter did not immediately announce a replacement for Garg, whose departure comes just two week after Costolo announced he was stepping down as the company's CEO.

Costolo has been replaced by co-founder Jack Dorsey on an interim basis.

Other high-level departures over the last 18 months include product chief Daniel Graf, COO Ali Rowghani, and CFO Mike Gupta.

Before joining Twitter, Garg was the M&A chief for fellow Jack Dorsey company Square.
