Turning brainwavesinto understanding.

I'm Tanvir Hossain Ovi, an EEG and brain-computer interface researcher. I build deep-learning systems that decode cognition, emotion, and identity from brain signals, and I study how immersion reshapes the way we think.

Inside the work

01 · Signal

Faint, noisy, and different in every person.

Scalp EEG is a few microvolts of brain activity buried under eye blinks, muscle, and line noise. Every head reads it a little differently.

Research focus

Five questions about the signals we carry

My work sits at the intersection of signal processing and deep learning. I'm mostly asking what EEG can tell us about the mind, and where it quietly stops being able to.

01

Cognitive Load & Immersive Environments

I compare 360° VR and 2D laptop viewing to see how immersion changes mental workload. Theta-alpha ratio and engagement index do most of the talking.

02

EEG Biometrics & Security

Different EEG frequency bands carry different kinds of information. Some are good at reading what a person is doing, others are better at recognizing who they are. I'm trying to find exactly where that split happens.

03

Emotion Recognition & Personalization

EEG-based emotion recognition tends to fall apart when you test it days or weeks later. I build phenotype-aware models that adapt to each person's neural patterns instead of correcting everyone the same way.

04

Imagined Speech & Accessibility

Decoding imagined English and Bangla speech from EEG, aimed at assistive communication tools for people with limited motor control.

05

Intracranial EEG & Reliable Evaluation

I model cross-channel structure in intracranial EEG and design recording-level evaluations that prevent windows from the same recording leaking across train and test sets.

From signal to system

Inside the experimental setup

Both conditions of the cognitive load study used the same 14-channel dry EEG headset, so the only variable was the display: a 2D laptop screen or a fully immersive VR headset.

Moments along the way

Second in a cohort of 63 in Electrical and Electronic Engineering, and a habit of finishing near the top that started well before university.

Selected builds

Tools I built and use

I build web apps around problems I run into, from practising Japanese to keeping shared expenses and graduate applications organised.

Japanese speaking and recall practiceLive

Kotoba

I built Kotoba to learn the Japanese introduction for my TMU interview. Word cards, audio and sentence-building practice turn a script into short daily sessions. Fading prompts and timed rehearsal help me practise speaking without reading every line.

Mess & meal management PWALive

Haowa Bhobon

A shared-mess operations app: daily meals on and off, per-member bazar (grocery) tracking, duty rosters, bills, and an automatic month-end settlement that splits every taka across members.

Let's talk about EEG, BCI, or a research collaboration.

Reviewing one of my graduate applications, or just curious about phenotype-aware EEG models? I'd love to hear from you.
