Ramdhan Hidayat

Background in Physics (BSc) and Data Science (MSc). Preparing for PhD-level research while building evaluation-driven AI systems, data pipelines, and agent tooling.

Research Interests & Focus Areas

  • Agent Architectures & Skill Optimization: Designing inspectable agent workflows, reusable skill artifacts, and evaluation loops that improve behavior without relying on ad hoc prompt tweaking.
  • LLM Evaluation & Alignment: Studying behavioral failure modes such as sycophancy, reward hacking, prompt bloat, and noisy benchmark selection.
  • Reinforcement Learning & World Models: Exploring how agents learn, plan, update internal representations, and make decisions under uncertainty.
  • Text & Multilingual Networks: Using graph theory and NLP to map semantic, rhetorical, and behavioral structure across languages.
  • Human-Centered AI Systems: Building tools that reduce cognitive load while keeping decisions, provenance, and failure modes visible.

Selected Projects

  • Bayesian Evolutionary Skill Optimization: Research prototype for optimizing LLM agent skills with Bayesian surrogate modeling, acquisition-based candidate selection, validation gates, and Pareto-style trade-offs.
  • Resume Optimizer: LLM job-application pipeline with conversational UX, Supabase-backed state, and provenance/event tracking.
  • LLM Text Network Analysis: Graph and NLP pipeline for extracting semantic structure from multilingual text datasets.
  • SycoBench: Benchmarking and evaluation work around sycophancy and behavioral tendencies in language models.
