About

My name is Haytham ElFadeel. I am a founder, self-taught machine learning scientist, engineering executive, and former alpine climber and cyclist.

From 2009 to 2017, I founded and led Kngine Inc., which aimed to solve the challenge of automatic knowledge acquisition, representation, and comprehension - basically ChatGPT before the GPT. My work focused on open-domain question answering, web-scale knowledge extraction, organization and representation, and natural language understanding.

In 2016, we built one of the precursors to BERT/GPT - a large foundational model that could answer questions. In 2017, Kngine Inc. was acquired by Samsung.

Before founding Kngine, I contributed to diverse research areas, including online handwriting recognition for Arabic, multilingual named entity recognition (NER), multi-kernel operating systems, and the development of a parallelism SDK for programmers.

From 2017 to 2020, following Kngine's acquisition, I led a research organization at Samsung Research as a Director, focusing on natural language understanding, open-domain question answering, and machine translation.

From 2020 to 2022, I worked at Meta as a Machine Learning Scientist and Senior Engineering Manager, leading multi-team organization and contributing to advancements in LLM, machine comprehension, and natural language understanding.

From 2022 to 2024, I served as a Senior Engineering Manager at Cruise (autonomous vehicles), where I led a organization responsible for :

Agent Simulation - model agent behavior, generating controllable and diverse road-user behavior in simulation.
Scenario Generation - using ML (e.g., Diffusion, GPT) to generate scenarios for uncovering AV issues and training the AV policy.
Applied Research - focused on the intersection of computer vision, simulation, and reinforcement learning (e.g., RLHF/RLVR, Noise Modeling, end-to-end perception, NeRF, 3D skeletons and animation).
Behavior Modeling - model ego behavior (planning) responsible for generating controllable and safe behavior.

Currently, I’m on a research sabbatical, conducting research in advanced ML/LLMs - exploring topics such as Autonomous Agents, Reasoning in LLMs, Reinforcement Learning, credit assignments problem, and some fringe topics in representation.

Outside of my professional endeavors. I was a semi-professional cyclist from 2015 to 2020 and a semi-professional alpine climber from 2020 to 2025.
