Hi there!

I'm Itir Sayar

A PhD student in Computer Science at UMass Amherst, where I also completed my undergrad with BS degrees in CS and Neuroscience.

I build closed-loop wearable systems with neurophysiological sensing for everyday health and wellness.

My research spans designing unobtrusive sensing systems, running user studies for human data collection in daily-life scenarios, and building machine-learning models that close the loop between those signals and the people.

What I work on
01 · SENSE

Sense

Designing ubiquitous systems that capture physiological signals from people in everyday, real world scenarios.

EEGEDAEye tracking
02 · MODEL

Model

Developing machine-learning models, mainly self-supervised and multimodal methods, that turn physiological streams into reliable representations.

Self-supervisedMultimodalFoundation models
03 · UNDERSTAND

Understand

Connecting those representations to human cognition, emotion, and behavior, then closing the loop with systems that adapt to people.

Music Perception via Physiological Signals

Decoding musical factors such as genre, tempo, mode, and register directly from EEG and EDA signals.

Multimodal Physiological Sensing for Engagement

A deep-learning model fusing EEG, EDA, and eye tracking to model viewer engagement during educational content, treating engagement as a rich multimodal signal rather than a single self-reported number.

Undergraduate
2023 – '24
Lymphoma Survival Prediction via Radiomics

Honors thesis (Biomedical Imaging & Data Science Lab). An ML/radiomics pipeline for progression-free survival in DLBCL from 3D PET imaging. Submitted to the SNMMI AI 2023 Challenge.

Summer '23
Biologically-Inspired RL with TD3

At the BINDS Lab. Combined muscle memory with TD3 + dynamic gating, cutting computational cost ~60% while holding performance across long action sequences.
