Timeline

  1. 2018–2020

    Research at VIT-AP

    He works as a Research Assistant at VIT-AP's Artificial Intelligence and Robotics Center from 2018 to 2020.

  2. 2022

    An open hotword detector

    In 2022, he coauthors EfficientWord-Net, an open-source hotword detection engine that detects hotwords in real time from one or a few training samples.

  3. 2022–2024

    Financial misinformation research

    From 2022 to 2024, he works as a Research Assistant in the Data Mining Lab at Illinois Institute of Technology. In 2023, he coauthors a survey of online financial misinformation that reviews its types, sources and impacts.

  4. 2024–2025

    Research Engineer at Ai2

    He works as a Research Engineer at Ai2 from 2024 to 2025. In 2025, he coauthors Olmo 3, a family of fully open language models.

  5. 2025

    Fin-Fact benchmark

    In 2025, he coauthors Fin-Fact, a benchmark for multimodal financial fact-checking and explanation generation. It contains 3,369 financial claims with truthfulness labels, rulings and textual and visual evidence.

  6. 2025

    Multimodal claim verification

    In 2025, he coauthors a study introducing multi-hop multimodal claim verification. It presents MMCV, a dataset of 15,000 claims paired with multimodal evidence, and reports that multimodal language models struggle as reasoning hops increase.

  7. As of October 2026

    Research Engineer at Stealth

    As of October 2026, he is a Research Engineer at Stealth and works on LLMs focused on long-context understanding.
