I recently graduated with an MS in Computer Science (specializing in Machine Learning) from Georgia Tech and am working as a Software Engineer at NCR.

I am currently working with Prof. Srijan Kumar as a graduate student researcher. We are developing a reputation system for Birdwatch , Twitter’s new notes-based, community-driven feature to address misinformation. Apart from designing new note-ranking metrics that would be robust against manipulation attacks, we are also quantifying user reliability in writing and rating notes

I had a great time working as a Research Intern in Summer 2020 at IBM Research, working with the Cloud Services Design Analytics group. The internship was a very fulfilling and fruitful experience with the following outcomes:

  • A patent filed with the USPTO (first-author)
  • A poster published at INFORMS2020 : "Best Poster (Honorable Mention)" Award
  • Productionized model, contributing to 30M USD cost-savings

    • Prior to commencing my MS degree in Fall 2019, I worked in NLP Research and Engineering at the AI startup Froot Research, where I was one of the first few employees and was mentored by the founder Amit Gautam.

    I earned a Bachelor's degree in Computer Engineering in 2017 from Vishwakarma Institute of Technology, Pune, where I was advised by Dr. Manasi Patwardhan.

    In my spare time, I like learning and shooting dance videos. You can see a few of them on my YouTube channel. I practice Yoga everyday and am an ardent promoter of mental health awareness.

    Research Interests

    My research interests lie in Applied Machine Learning particularly in Natural Language Processing and Knowledge Graphs. I am especially interested coupling ML/NLP/Graph Learning with social media, online communites and with computational social sciences.

    Selected Projects
    3DSP Do Scientific Ideas Originating from more Prestigious Universities Spread Faster?
    Rohit Mujumdar, David Kartchner
    (Data Science for Epidemiology, Fall 2020. Georgia Tech)
    Keywords: epidemiology, microsoft academic graph, natural language processing, epistemiology

  • Investigated the imbalance in the spread of ideas across academic research networks caused due to differences in academic prestige using disease spread models adapted from epidemiology. .
  • Assessed if idea spread is driven by connectivity amongst original authors or the explicit prestige of their institution
