How do the visual mechanisms that underlie learning and cognition develop during early childhood, and what rules govern their developmental trajectory? This is a fundamental open question in developmental neuroscience and one with direct consequences for how we identify and support children at risk for reading difficulties and neurodevelopmental conditions.
The Functional Vision Lab addresses this question from both ends: controlled psychophysics to isolate basic visual mechanisms, and large-scale studies in diverse school populations to reveal heterogeneity in neurodevelopmental trajectories, ultimately informing precision screening and intervention tools that reflect the full spectrum of neurodiversity.
The FVN Lab is growing. We welcome curious, cross-disciplinary researchers who care about equity in science and want to make a real difference in children's lives.
We uncover the developmental principles that govern how core visual mechanisms such as crowding, attention, temporal encoding, and early visual representation emerge and integrate during early childhood, shaping the trajectory of learning and cognition.
We investigate the visual and neurodevelopmental mechanisms behind reading difficulties. Our work has shown that children with dyslexia show differences in visual encoding but no deficit in spatial attention, helping resolve two decades of ambiguity in the field.
We design gamified online assessments that can be administered broadly across languages and socioeconomic backgrounds, making early screening for reading difficulties accessible to all children.
To understand the intersection of basic visual mechanisms and neurodevelopmental conditions, and to use that understanding to create effective early screening tools and evidence-based therapeutic and remediation programs.
To conduct rigorous research in large and demographically diverse populations, with the belief that inclusive science can bridge health and education disparities for children worldwide.
Great science comes from diverse perspectives and genuine collaboration. Meet the team.

Dr. Ramamurthy is a developmental cognitive neuroscientist and vision scientist whose work sits at the intersection of functional vision and the development of cognitive abilities in neurodiverse populations. Trained across optometry, psychophysics and cognitive neuroscience, she studies how functional vision develops in early childhood and how variability in visual mechanisms shapes learning trajectories in cognitive abilities such as reading.
The lab sits at the intersection of basic visual science and real-world learning outcomes. Our research spans fundamental mechanisms, developmental trajectories and scalable tools that can reach children across diverse populations.
We work on understanding the developmental principles that govern how functional vision develops in early childhood.
We study how variability in early visual mechanisms maps onto the development of cognitive skills and onto the spectrum of neurodevelopmental profiles. This gives us the insights needed to move toward precision intervention.
We translate basic science into tools that are rapid, equitable, and built to work across languages and socioeconomic backgrounds.
Precisely controlled experiments measuring perception, attention and visual processing with millisecond-level accuracy. The foundation of our mechanistic work.
Recording eye movements and fixation patterns to understand how children and adults allocate attention and navigate visual information during reading and related tasks.
Neural recordings that reveal the timing and nature of visual processing, allowing us to localise where in the brain and at what stage differences arise.
Child-friendly, browser-based assessments designed to engage young participants while collecting high-quality data. Built for scale and accessibility across diverse settings.
Large-scale studies in schools and communities, testing whether lab-based findings hold in real-world, demographically diverse populations.
Formal models that generate testable predictions about visual mechanisms and developmental trajectories, bridging behavioural findings with neural and computational theory.
India offers a uniquely powerful scientific context: a vast, multilingual, multi-script population with enormous variation in educational environments and socioeconomic backgrounds. This diversity is not just an opportunity for scale but a genuine scientific advantage for testing what is universal in visual development and what is shaped by experience.
The lab will pursue large-scale developmental studies in Indian school populations, building normative data on functional vision across age groups and linguistic contexts. Clinical partnerships will allow us to validate measures against gold-standard assessments and understand how visual processing differences relate to broader neurodevelopmental profiles.
The long-term goal remains unchanged: to translate rigorous basic science into tools and knowledge that genuinely help children who are struggling, wherever they are.
The lab actively welcomes new partners. If your work intersects with ours, we would love to hear from you.
Teaching and mentorship are central to how the lab works. Below is Maha's teaching philosophy and journey, shaped by work across India, Canada and the US.
Maha's teaching began right after her optometry degree in India, teaching neuroanatomy and physiology to pre-med and optometry students. At the University of Waterloo she tutored physiological optics and colour perception, and built a set of demonstrations to help students grasp concepts in perception and optics. The through-line across these experiences has been designing active learning that reaches students from very different starting points.
Teaching full undergraduate courses at UMass Boston, where many students were first-generation or returning after a break, required rebuilding the syllabus around example-building and demonstrations. Assignments asked students to generate their own examples for each concept; pre- and post-class quizzes surfaced where reinforcement was needed; informal conversations before class served as ongoing check-ins. This kept the curriculum responsive to where each student actually was.
These experiences taught her to read a classroom's starting point and reshape teaching accordingly. She carries the same approach into graduate mentoring and into the teaching she does at IIT Gandhinagar today.
Science communication, writing, community work and other activities that sit at the edges of the lab, but are just as important to who we are.
Maha enjoys being in nature and traveling to learn about people, their worldviews and ways of life.
She also paints, writes poetry, plays musical instruments, throws pottery, practices natural farming, hikes, cooks, and generally tinkers.
Maha writes about her travels and ongoing work. Older pieces are being digitised.
