Work Experience

2024 July – present: Data Scientist III at Ericsson, Bengaluru.
Working on Knowledge distillation techniques of LLMs to SLMs and fine-tuning SLMs to create a more refined model suited for specific use cases.

2022 March – 2024 June: Data Scientist II at Ericsson, Bengaluru.
Worked on Trustworthy AI, Responsible AI and Explainable AI techniques. Implemented ChatBot using RAG technique to deal with telecommunication data using AWS Claude model with dockerization and interfacing with vertical database. Developed automated compliance detection system for AI systems to adhere to trustworthy AI guidelines. Contributed in the development of an in-house python package for application of explainability on various data using various explainable techniques like SHAP, LIME, etc. Implemented anomaly detection on time series telecom data, eventually bringing new business to the company.

2021 February – 2022 February: Research Investigator at Syngene International Limited, Bengaluru. Responsibilities include analysing real-world datasets to build useful machine learning models for multiple clients in various domains, including bioinformatics and chemistry.

Research

Currently, my role in Syngene International involves building machine learning models for chemoinformatics data. Before this, I obtained a Ph.D. in Computer Science from Machine Intelligence Unit of Indian Statistical Institute, Kolkata. My research interests are in Data Engineering, Data Science, Data Analysis, with a focus on designing algorithms, data pre-processing techniques and pipelines using machine learning algorithms.

• Designed a system based on Boolean networks that analyses biological networks.
• Invented an over-sampling algorithm for an ensemble learning classifier for effector proteins.
• Designed a novel graph based system to predict the effect of toxins on unknown metabolic pathways.
• Developing deep learning and ensemble models for the identification of effector proteins.
