About Me

I am an AI Applied Scientist with expertise in developing and deploying enterprise-scale Generative AI systems. I have hands-on experience in architecting AI-based solutions and multi-AI-agent systems with a strong emphasis on safety, robustness, and responsible deployment.

I obtained my Ph.D. in Computer Science at Washington State University where I was advised by Professor Jana Doppa. My general research interests are in robust and trustworthy machine learning. My PhD research focused on developing efficient algorithms and theory to improve reliability and safety of deep learning algorithms across diverse domains. My research work includes:

  • Robustness and reliability of deep learning models for the time-series domain with diverse applications including mobile health, smart grid management, human activity monitoring, and agriculture automation.
  • Trustworthy machine learning for sequential data.
  • Uncertainty quantification for robust and effective Human-ML collaborative systems using conformal prediction.

Projects

Tech lead in AIRefinery

I am a Technical Lead in the design and deployment of AI Refinery™ agentic AI systems that translate advances in generative modeling and reasoning into production-ready platforms, enabling organizations to transform raw AI capabilities into reliable business solutions. I contribute to building and evaluating scalable multi-agent workflows that support complex enterprise decision-making across diverse application domains. This work is complemented by the development of an SDK that allows organizations to build, customize, and securely deploy agentic AI applications across cloud and on-premise environments.

Robustness and reliability for deep learning models

My research develops deep learning algorithms for the safe deployment of machine learning models operating under real-world perturbations such as noise, temporal shifts, and distributional distortions. I design robust training objectives and similarity measures that improve model reliability when standard distance metrics fail under natural or adversarial transformations of the input space. I also investigate methods for detecting out-of-distribution inputs to prevent overconfident predictions in safety-critical environments. I have also worked on theoretically grounded uncertainty quantification techniques, including conformal prediction, to enable calibrated and trustworthy decision-making in human-AI systems.
