Alex Damian
Also known as Alexandru Damian
Alex Damian is a mathematician and MIT assistant professor who studies how neural networks learn and how their training algorithms behave. He earned a mathematics BS at Duke University and a PhD in applied and computational mathematics at Princeton, where Jason Lee supervised his work. He coauthored work on PULSE in 2020, which generates detailed faces from low-resolution images, and MeZO in 2023, which reduces the memory needed to fine-tune language models. After a Kempner Research Fellowship at Harvard, he joined MIT's Mathematics and EECS departments in 2026. He was named a 2026 AI2050 Early Career Fellow for a project that develops mathematical methods for choosing neural network training procedures.
Timeline
-
2016
An Angier B. Duke scholarship
A graduate of Devon Preparatory School in Pennsylvania, he receives an Angier B. Duke Memorial Scholarship for undergraduate study at Duke University in 2016.
-
2020
PULSE generates detailed faces
At Duke University, he coauthors PULSE in 2020 as part of Cynthia Rudin's team. The system searches images made by a generative adversarial network to create detailed faces that match a low-resolution input when reduced in size.
-
2022
Learning representations with gradient descent
With Jason Lee and Mahdi Soltanolkotabi, he coauthors Neural Networks can Learn Representations with Gradient Descent at the Conference on Learning Theory in 2022. For problems with low-dimensional structure, the work shows how gradient descent trains a two-layer neural network to learn representations relevant to its task.
-
2023
MeZO for language models
He coauthors Fine-Tuning Language Models with Just Forward Passes at NeurIPS in 2023. The team introduces MeZO, an optimizer that fine-tunes language models using forward passes with the same memory footprint as inference.
-
2024
Transformers learn causal structure
With Eshaan Nichani and Jason D. Lee, he coauthors How Transformers Learn Causal Structure with Gradient Descent at ICML in 2024. On a designed learning task, they prove that a simplified two-layer transformer trained with gradient descent learns to encode a hidden causal graph in its first attention layer.
-
2025
A doctorate at Princeton
After a BS in mathematics at Duke University, he completes a PhD in Princeton's Program in Applied and Computational Mathematics, supervised by Jason D. Lee. His final oral public examination in June 2025 presents Foundations of Deep Learning: Optimization and Representation Learning, a thesis on representation learning and optimization dynamics.
-
2025
Kempner research fellow at Harvard
In 2025, he becomes a Kempner Research Fellow at the Kempner Institute for the Study of Natural and Artificial Intelligence at Harvard University. He studies how training methods, including stochastic gradient descent and Adam, shape the representations learned by neural networks.
-
2026
An AI2050 fellowship
In 2026, he is named an AI2050 Early Career Fellow. His project develops a mathematical theory of how optimizers interact with neural network architectures, with the aim of deriving effective training procedures automatically.
-
Since 2026
Assistant professor at MIT
In 2026, he joins MIT as an assistant professor with a shared appointment in the Departments of Mathematics and Electrical Engineering and Computer Science through the Schwarzman College of Computing. He is also a member of LIDS and studies the mathematical foundations of deep learning, including optimization dynamics and representation learning.
