Movement Lab - Manoj Srinivasan

We are interested in understanding the movement of things: humans, other animals, and machines.

Some central scientific questions are: Why do animals move the way they do? And how do they do it so well? We are interested in obtaining a simple and tractable, yet complete, theory of legged locomotion and sensorimotor control in humans and other animals -- a theory that will reliably predict how an animal will act in a novel situation (say, humans on the moon), how the animal will respond to perturbations (say, stepping on a banana peel), or how we should design better wearable robotics such as robotic prostheses and exoskeletons and other biomechatronic assistive devices. We use a mixture of mathematics, modeling, computation, and experiments.

The Movement Lab is located within the Department of Mechanical and Aerospace Engineering at the Ohio State University and is led by Manoj Srinivasan.

We hosted the Dynamic Walking Conference (2015) at Ohio State.

Prospective students and post-docs:

While we always welcome emails from all students and others from near and far, we may not consider taking on additional students at this point, for the next 6 months. We realize that writing a letter of application to a faculty member takes time, effort, and research, and we provide this information so that you can allocate your attention and resources most effectively.
