My calendar (office hours: WTh 5-6 PM)

I work on developing learning based methods mostly for audio processing (music, speech, and other sounds). I have interest in Physics, so I work with Physicists to develop learning based methods for problems in computational Physics too.

I received my B.Tech. and Ph.D. degrees in Electrical Engineering from the Indian Institute of Technology (IIT) Kanpur, India. My Ph.D. thesis was titled “Analysis of Pitched Polyphonic Music for Source Transcription”, where I worked on analyzing music audio to identify and transcribe different instruments/voices playing simultaneously. During postdoc at Oxford University (UK), I developed speech recognition systems using linguistic principles, with applications in automatic language teacher and speech recognition for low-resource languages. At Amazon in Boston (USA), I worked on audio classification for developing Alexa home security system, with research focusing on classification with imbalanced data.

Research interests:

  • Machine learning for audio signal processing
    • audio retrieval: multi-label classification
    • melody estimation: transfer learning
    • speech recognition: confidence estimation
    • music analysis: explainable AI
  • Machine learning for Physics
    • generative modeling, normalizing flows, adversarial learning
  • Time series analysis on sensor data
    • Sensor calibration: domain adaptation, semi-supervised learning
