👨‍💻 I am a Research Engineer/Scientist in the OCTO and SATG (Office of the CTO and Software Advanced Tech Group) at Intel Corporation, Santa Clara (CA), where I work on research and development of software for Extreme Scale Graph Analytics. I previously worked as a Software Engineer at NCR Coproration. I graduated from Georgia Institute of Technology in Spring 2021 with an MS in Computer Science and a specialization in Machine Learning + Social Computing.

🔬 I collaborated with Prof. Srijan Kumar to develop HawkEye, a reputation system for Birdwatch (now called Community Notes), Twitter’s community-driven feature to address misinformation, which was the first research study on Birdwatch and was successful in influencing the Birdwatch platform. Our paper based on this work got published in ASONAM'21.

🚀 I interned with the Cloud Services Design Analytics group at IBM Research. I filed a patent based on my work and also authored a poster, which won the Best Poster (Honorable Mention) award at INFORMS'20

🍋 Prior to commencing my MS degree in Fall 2019, I worked as an Data Science (NLP Research) at Froot Research, (now acquired by Aarav Solutions). As one of the first few employees of an early-stage AI start-up, I 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.

🎥 I run a video podcast, 'Talking To The Moon', where I interview people across professions and walks of life and listen to the stories they have to tell. More about the idea behind the vodcast in this article.

💃🏻 Dancing is one of my hobbies (a few of my dance videos). I am an avid practitioner of Yoga and an ardent promoter of mental health awareness.

🎤 I am an active member of and VP of Public Relations for the iNCRedible Toastmasters Club. I am on Level 2 of the Presentation Mastery pathway.

📧 Feel free to drop me an email or DM me on Twitter; I love making new friends and am always open to interesting conversations!

My interests lie in Applied Machine Learning and Data Science, in which I am particularly fond of Computational Social Science/Social Computing. Projects involving graph datasets and graph analytics have been a common theme in my jounrey. I have lately also been interested in Graph Neural Networks and Data Centric AI.

Ontology learning process involves identification of concepts and the relationships between these concepts. Automated ontology learning based on ML/DL techniques identifies these triples but suffers from the problem of duplicate or simialr rrelationships. We propose a solution to identify simialr relationship so that the ontology can be fine-tuned.

We investigate the disparity between English and non-English language models and show that detection frame-works based on pre-trained large language models like BERT and multilingual-BERT systematically perform better on the English language. We demonstrate the promise of incorporating the information contained in images via multimodal machine learning to address this disparity.

We investigate the robustness of Birdwatch against adversaries and show that the current Birdwatch system is vulnerable to manipulation attacks. To overcome this vulnerability, we develop HawkEye, a cold-start-aware graphbased recursive algorithm, and show that it is more robust to such attacks.

We use statistical analyses and regression-based techniques to predict the resolution times of incident tickets. We employ techniques like dynamic rolling window, auto-regressive window-flip and artificial data creation handle data eccentricities.
