I'm a Ph.D. Student in the Dept. of Computer Science at Stony Brook University. I'm working as a Graduate Research Assistant at the PACE Lab. I'm advised by Prof. Anshul Gandhi and Prof. Erez Zadok. My research interests span across Distributed Systems and Peer-to-peer Networks.


I received B.Tech in Computer Science Engineering from the Indian Institute of Technology (IIT) Bhilai in 2022. I have previously worked as a part-time Software Engineer Intern for 2 years at DMLab, Chile.


Experience

  • Reliability of Server Components

    Supervisors: Dr. Anshul Gandhi and Dr. Erez Zadok

    • Reliability: Estimating reliability impact on server components due to workloads.
    • SSDs & HDDs: Built regression models for predicting the Remaining Useful Lifetime (RUL) of SSD/HDDs from SMART values. Models can predict RUL with an MAE of ∼13 days.
    • Per-job RUL impact: Building a model to estimate SMART values based on job profile and component load, and further predict per-job RUL impact on the component.
    • DRAM: Building a regression model to predict RUL of DRAM from DRAM error logs. Training on publicly available error logs datasets.
    • Novelty: Prior works employ classification models to predict whether a component will fail within a certain window, we use regression models to predict per-job impact on the RUL of the component.

  • Per-job Operational and Embodied Carbon Emissions

    Supervisors: Dr. Anshul Gandhi and Dr. Erez Zadok

    • Per-job Power Prediction: Tracking per-job resource usage in servers using perf-stat and blktrace, and predicting power consumption of each workload using ML models.
    • Evaluating ML models: Extensive evaluation of a wide variety of ML models with various power model formulations. The final XGBoost model could predict per-job operational power with ∼7% MAPE.
    • Embodied carbon: Built a model to predict embodied carbon emission from the server configurations.
    • Monitoring tool: Developed a resource monitoring tool to analyze the usage of server components in real-time and report per-job embodied share per-unit time.
    • ACCEPTED at HotCloudPerf 2024: Empirical Evaluation of ML Models for Per-Job Power Prediction - DOI.

  • Research Fellowship from Arista Networks

    Supervisor: Dr. Anand M. Baswade

    • Real-time IDS for WPA3: A two stage architecture for real-time intrusion detection for an enterprise scenario.
    • Attacks on WPA3 testbed: A new, open source dataset for attacks on WPA3-enabled device.
    • ML based IDS: A lightweight ML-based classifier for attack detection with high accuracy in real-time.

  • Research on SDN in Satellite Networks

    Supervisor: Dr. Anand M. Baswade

    • QoS aware routing: Developed an algorithm better than Dijkstra to find the shortest as well as QoS aware route in a Satellite Network.
    • Protocols for flow rule transfer: Developed protocols for flow rule transfer in SDN which ensure non-disruptive service during satellite handovers.
    • Visualizations: fybrrLink Visualization Tool : fybrrLink-VizTool.
