Hi, I'm Roshan
I am a scientist and an engineer with broad interests, from behavioural neuroscience to automotive engineering. I take a hands-on approach to learning and believe the best way to pick up a new skill is by building something with it.
I earned my bachelor’s and master’s degrees in Biotechnology from IIT Kharagpur. After that, I moved to Austria for my PhD in Prof. Joesch’s lab at the Institute of Science and Technology Austria, where I studied the visual systems of invertebrates. You can find an overview of my PhD research here. If you’re more technically inclined, feel free to check out my thesis or the paper I co-authored.
I’m currently working as a postdoctoral fellow at National Centre for Biological Sciences Bangalore in the lab of Prof. Vatsala Thirumalai where I am studying the development of motor circuits in zebrafish.

My PhD project
For my PhD, I studied how the invertebrate visual system guides locomotion; in simpler terms, how do fruit flies see and walk. Yes, I am aware of the irony of studying how fruit”flies” walk.
On closedloop visual experiments
To study the visual system, I built a closed-loop behavioral setup that allowed us to present visual stimuli to a walking fruit fly and update the stimulus in real time based on the fly’s position and orientation. Stripping away the scientific context, the goal was essentially to display a pinwheel disc to the fly. Read more...
