Sundeep has been a wonderful mentor, and has always directed me to consider multiple aspects while looking at a problem - technically as well as at an inter-personal level! I have known him for about 2 years now, and he has helped me think critically while formulating an ML (research) problem, to meticulously analyze data, results, papers etc and much more! It was often fascinating to see the amount of time he would spend on giving detailed all round (technical, presentation, writing etc) feedback.
Further, my interactions with Sundeep has helped me understand more of what a PhD in ML would be like and what it would entail! It is nice to have someone who could share their rich first hand experience working/researching at top labs, large orgs and start-ups! More importantly, it was really helpful to have someone I could discuss deep technical problems related to machine learning research as well as someone who could provide suggestions on more broader career or educational directions!
