Biography

Jitendra Ajmera joined the Labs in 2005 as a senior research scientist. Prior to this, he was working as speech scientist at Reliance Infocomm, NaviMumbai, India.

He earned his Doctorate (Ph.D.) in Computer Science from Ecole Polytechnique Fédérale de Lausanne (EPFL), Switzerland in 2004. During this time, he was associated with IDIAP research institute, Martigny, Switzerland, as research assistant. He received his Bachelor of Technology (B. Tech) degree from Dept. of Electrical and Electronics Engineering, Indian Institute of Technology, Mumbai (IITB) in 1999.
