Laboratory of Data Quality and Intelligent Security, Department of Computer Science, Rochester Institute of Technology

Trustworthy data.
Intelligent security.

We build the methods, models, and systems that make modern data infrastructure verifiable, resilient, and worthy of trust, from sensor networks at the edge to large-scale machine learning at the core.

Each bar is a week of federated-learning experiments in InteFL: 2,471 runs since March 2026.See the experiment record

For over 20 years the lab has trained 25+ researchers and released 11 open-source projects, and Dr. Reznik's publication record spans 181+ papers, books, and chapters.

Research areas

Six frontiers we're pushing in parallel.

Our work sits at the intersection of data quality, security, and intelligent systems, with a hard focus on what's deployable, measurable, and trustworthy.

  • Federated Learning

    Privacy-preserving model training across distributed clients: designing protocols, aggregation strategies, and threat models for collaborative ML without centralizing sensitive data.

  • Data Quality at Scale

    Provable quality metrics for streaming sensor data, with frameworks for evaluating fitness-for-purpose across heterogeneous sources.

  • ML System Security

    Adversarial robustness, model integrity, and runtime monitoring for ML systems deployed in safety-critical environments.

  • Edge Intelligence

    Neural network architectures and inference systems designed for the power, privacy, and reliability constraints of edge deployment.

  • Verifiable Mobile Security

    Building on the lab's shipped Android apps (Android System Security Evaluation and Detector of Unverified Apps on Google Play) into continuous verification for app supply-chain integrity.

  • Open-Source Tooling

    Releasing reproducible benchmarks, evaluation frameworks, and reference implementations the community can build on.

Projects

What we're shipping right now.

Open-source frameworks, peer-reviewed methods, and end-to-end systems, built by the current cohort and used by researchers beyond LDQIS.

Research projects

The software behind the lab's studies: frameworks, testbeds, and experiments with research questions and papers behind them.

Federated Learning, Agentic AI

InteFL

Knowledge Management Framework for Federated Learning

A configuration and execution framework for federated learning simulations built on Flower. Implements novel PID controller-inspired and Trust-based aggregation strategies alongside classical robust methods (Krum, Multi-Krum, Bulyan, RFA, Trimmed-Mean), adversarial attack scheduling, federated LLM fine-tuning with LoRA, and a wide range of medical imaging datasets. Published in IEEE Intelligent Systems, 2026.

Built with Python, Flower, PyTorch, LoRA

2,471 experiments run so far with InteFL

Agentic AI, Software Engineering

Sphragis

A pre-registered study of what coding agents learn from code review

A coding agent becomes useful once it knows how an organization writes software: its internal APIs, error-handling patterns, naming rules, and what its reviewers reject. Sphragis tests whether that house style can be learned at all from an organization's public code-review history, and what a declared boundary protects once it can. The study is pre-registered: its pass rule is fixed in code and its test window is sealed before collection. It is written as a Registered Report for MSR 2027.

Built with Python, PyTorch, Transformers, PEFT

Federated Learning, Intelligent Security

Pharos

A labeled fleet testbed for federated personalization

Public corpora lack what a disclosure boundary needs: objects that carry real classification levels and cross-cutting compartments. Pharos generates a labeled body of reporting in which two holders can be incomparable rather than merely ranked, so the personal/shared split in federated personalization can be measured rather than asserted. A static explorer lets anyone browse the corpus.

Built with Python, PyTorch, PEFT, OpenTelemetry

Federated Learning, Adversarial Robustness

Phalanx-FL

Full-stack robustness platform, forked from InteFL

A platform for stress-testing federated learning under attack: configure, run, and compare experiments across 9 aggregation strategies, 11 adversarial attack types, and 20+ datasets, all from a React + FastAPI + Celery web app with live, streamed run monitoring. InteFL remains the lab's canonical research framework; Phalanx-FL is its robustness and tooling proving ground.

Built with Flower, FastAPI, React, Celery

Agentic AI, Sensemaking

Ariadne

Sensemaking for nonatomic entities using AI coding agents

Evidence about a single entity is scattered across graph, relational, and text stores, and analysts lose the thread at every pivot between systems. Ariadne uses an agentic harness built on the Claude Agent SDK as one analytic interface over that infrastructure: a single agent traces an entity's evidence across heterogeneous stores into a cited analytic narrative.

Built with Python, Claude Agent SDK, Neo4j, MCP

Federated Learning, Quantum ML

QFL Privacy

When do variational quantum circuits keep federated training data private?

Federated clients share gradients instead of data, and on classical networks those gradients can be inverted to rebuild the training inputs. For variational quantum circuits the literature disagrees. This project maps where each claim holds, across encoding depth, trainable layers, batch size, and simulated IBM Heron device noise, using gradient-matching attacks on 4- and 8-qubit circuits. A course project for CSCI-739 Quantum Machine Learning, Fall 2026.

Built with Python, PennyLane, Qiskit, JAX

Federated Learning, High-Performance

Velocity-FL

Rust-core federated learning orchestration

A federated learning runtime with a Rust aggregation core and a Python-first interface. Eight paper-cited aggregation algorithms (FedAvg, FedProx, Krum, Bulyan, Geometric Median, and more), round-level and data-pipeline attack simulation, and aggregation kernels measured at ~92× the speed of pure Python.

Built with Rust, PyO3, Python

Agentic AI, Multi-Agent System

Kourai Khryseai

A multi-agent system with three interfaces

Ten specialized A2A-protocol agents (planner, coder, tester, reviewer, scribe, validators) collaborate in a shared group chat to plan, build, and ship code, with every step observable through OpenTelemetry. One backend drives three interfaces: a terminal CLI, a Pygame GUI, and a Ren'Py visual novel. Presented at North-East AI Agents Day 2026.

Built with MCP + A2A, CLI, Pygame, Ren'Py

Agentic AI tools

Open-source tools for working with AI coding agents such as Claude Code, built for the lab's own research and free for anyone to use.

Agentic AI, Developer Tools

techne

A Claude Code plugin marketplace

Plugins for Claude Code: skills for code repositories (toolchain audits, CI log review, adversarial pre-merge review, cross-repo drift) and for documents (papers, slides, bibliography verification), opt-in git guards, and a spoken Claude Code.
