Accessibility & HCI researcher · PhD candidate, University of North Texas

Interfaces that work for the people they usually leave out.

I design and study programming tools for blind and low-vision users and for learners with ADHD, then ship them so real people can use them.

Three threads, one question.

How do we make computing usable for people it usually leaves out? I work on that question from three sides.

Blind & low-vision access

Making block-based programming environments like Google Blockly work with keyboards, screen readers, and audio cues, so visual programming isn't only for sighted students.

ADHD & programming

Studying how learners with ADHD experience programming, and building adaptive tools that reduce distraction and help with planning and debugging.

Human-computer interaction

The method behind both: co-design, surveys, usability studies, and qualitative analysis, so what gets built is grounded in how people really work.

    Focusly, an adaptive block-based programming tool for learners with ADHD

    The core of my dissertation. Focusly adds a hint system, a task breaker, a progress summarizer, a focus timer, and a reward system on top of a block-based editor, each one shaped by survey data from adults with ADHD. A co-design study is underway.

    Accessible Blockly for blind and low-vision programmers

    Research Assistant work in the DiscoverABILITY Lab: an extension-based accessibility framework for Google Blockly with keyboard navigation and an audio cue system whose sounds change with nesting depth. Funded by Google's Blockly Accessibility Fund.

    AI-AC, an accessibility checker for any website

    A published Chrome extension that scores a page per disability profile instead of one flat list. A local rules engine mapped to WCAG 2.2 runs free; an optional AI vision pass reads a screenshot the way a person sees it and catches text baked into images, meaning carried by colour alone, and mismatched alt text.

    Strangers Connect, real-time video chat

    A full-stack app that connects people worldwide: peer-to-peer WebRTC video, Socket.io signalling, end-to-end encrypted messaging, dark and light themes.

I care most about the moment something finally clicks for a learner who was told the subject wasn't for them.
Vamsi Krishna Kosuri

I'm a fourth-year PhD candidate in Computer Science at the University of North Texas, advised by Dr. Stephanie Ludi in the DiscoverABILITY Lab. I expect to graduate in May 2027.

My research asks a stubborn question: the tools we build for programming and learning assume a certain kind of user, so what does it take to make them work for everyone else? That takes me from screen-reader semantics and audio interfaces to the lived experience of neurodivergent students, and to shipping real tools like AI-AC.

I move between research methods and engineering because good accessibility needs both: evidence about people, and software that actually runs. I'm from Visakhapatnam, India, and I speak Telugu and English.
