Sai Krishna Rallabandi

Am a PhD student in Language Technologies Institute at Carnegie Mellon University working with Prof. Alan Black. I actually consider myself the CTO of Alan Black Research Lab. I will design most of the pipeline in our submissions to speech related challenges so you know whom to blame if CMU doesnt do well. Talk to me if you want to be a part or take up a significant portion from me for a particular challenge.

Most of my thought process right now is occupied with excitement for PhD at CMU. I am fortunate to have fellowship by Facebook for same.

CV: Sai Krishna (Updated September, 2019)
Statement of Purpose (2018): PhD, CMU (Thanks Shrimai, Sunaina, Pallavi, Sumit, Khyathi and a thousand others!! who helped turn my rubbish into this)
Statement of Purpose (2016): PhD, CMU I got into MLT

Productivity Reports: I was also a Masters student at CMU prior to my PhD admission. To me a Masters degree is about synthesis of existing knowledge. Hence I have dealt it as in industry. This means keeping productivity as a first class object
