Points of Pride
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 Engineering at the Ohio State University and is led by Manoj Srinivasan.
A few years ago, we hosted the Dynamic Walking Conference (2015) at Ohio State.

I find passive voice indirect. I avoid passive voice when appropriate, but not always. In this context, I love the following comparison: "why did the chicken cross the road?" versus "why was the road crossed by the chicken?"
Here's a beautiful essay on how to write an article containing mathematics. The intended audience of this essay was MIT undergrads, but the lessons are broadly applicable. The part about language on pages 3-8 is especially compelling.

Good programming style. Here's one on MATLAB programming style guidelines, in which the author quotes regarding variable naming, "A rose by any other name confuses the issue."
The PLOS family of journals had series of essays called "Ten Simple Rules," covering various topics of general interest: ten simple rules for getting published, for getting grants, for reviewers, for selecting a postdoctoral position, for a successful collaboration, for making oral presentations, for a good poster presentation, for doing your best research, for graduate students, organizing a scientific meeting, etc. Here are all the ten simple rule essays in a single PDF file.
