Moshe Mash, Ph.D.

AI Researcher · Multi-Agent Systems, Human-AI Collaboration & NLP

I am an AI researcher who studies how people and intelligent agents can work well together. My work brings together multi-agent systems, game theory, and machine learning, with an applied line of research in natural language processing and large language models.

My research follows three main directions. The first asks how humans and computer agents interact, coordinate, and reach agreements in shared environments, and how to design agents that act well alongside people. The second studies the people who build AI: how machine learning practitioners and data scientists work, and where they get stuck, so that tools can help at the right moment. The third develops LLM-based methods that extract structure and meaning from large collections of specialized text, for example predicting the authors of historical texts whose attribution has long been disputed.

I hold a Ph.D. in Software and Information Systems Engineering from Ben-Gurion University and was a postdoctoral fellow at Carnegie Mellon University. My work received the Best Paper Award at the ACM Conference on Economics and Computation (EC 2016) and was selected as a Communications of the ACM (CACM) Research Highlight (2018), with publications in JACM, AIJ, ACM TIST, CHI, IJCAI, and AAMAS.

Alongside research, I have more than a decade of hands-on industry experience taking AI systems from research to production. At Amdocs I designed and deployed, end to end, a churn-prediction system that saved millions of dollars; at DICTA I develop AI models for understanding large collections of text; and through MashInnovateAI, the AI R&D consultancy I founded, I help companies solve their core challenges with AI.

I have taught at five institutions, twice received Ben-Gurion University's Excellence in Teaching Award, and mentored students at Ben-Gurion University and Carnegie Mellon University. I serve as a reviewer for AAAI, IJCAI, AAMAS, KDD, CHI, EC, and ECAI.

Experience

Academic Positions

Postdoctoral Researcher

Carnegie Mellon University, Robotics Institute 2019–2022

Hosts: Prof. Reid Simmons and Dr. Stephanie Rosenthal

My research studied the people who build AI systems: how machine learning practitioners and data scientists work as they develop models, and where they get stuck. I developed DSWorkFlow, a framework that captures data scientists' workflows from Jupyter notebooks, reconstructs the order in which code was executed, and combines it with qualitative data, and used it in studies of data scientists building machine learning models (CHI). Building on that data, I developed a model that predicts stuckness from real-time indicators such as code artifacts, and an algorithm that times an intervention as close as possible to the onset of stuckness (VL/HCC).

I mentored computer science students. The research was funded by J.P. Morgan, which renewed the award for a second consecutive year based on the project's results.

Professional Experience

Principal AI Researcher & Founder

MashInnovateAI 2024–Present
  • Independent AI R&D consultancy: helps companies identify where AI can solve their core challenges, then designs and delivers the solution end to end, from proof of concept to production
  • Clients include technology companies integrating AI into their products and workflows, startups, and universities and academic research groups

AI Researcher

DICTA – The Israel Center for Text Analysis 2022–Present

I lead the center's NLP and LLM research on large collections of Hebrew and rabbinic texts: setting the research agenda, designing the methods, and taking systems from prototype to tools in active use by scholars. The work combines fine-tuned LLMs and custom text embeddings trained with contrastive learning for domain-specific corpora, powering information extraction, semantic search, text similarity, clustering, and question answering over long, complex documents, together with deep-learning models for morphological, syntactic, and semantic analysis of long documents at scale. I built the end-to-end training and inference pipeline, with tooling to analyze model outcomes and inspect the training process, and deployed the resulting document-understanding systems to production.

Example projects:

  • Authorship attribution: models that predict the author of texts with historically disputed attribution from textual signals alone, reaching high accuracy and resolving long-debated questions of authorship
  • Citation detection and cross-referencing: systems that automatically detect, extract, and link citations of classical sources across a large corpus, connecting documents that quote or paraphrase one another
