Introduction

I am currently the Program Manager for the Robotics Research Group (RRG) at The University of Texas at Austin and a Lecturer in the Department of Mechanical Engineering at UT.

I completed my undergraduate studies at Southern Methodist University in 1993. After spending 2 years teaching at St. James School in St. James Maryland, I was accepted to the PhD program at UT. I earned my doctorate in Mechanical Engineering in 2002 with an emphasis on the modeling, simulation, and operation of redundant serial chain manipulators. I since earning my Ph.D, I have been teaching graduate and undergraduate courses and performing research in the area of robotics. My complete CV is available here (pdf).

Research Interests

Robots are no longer the industrial monoliths we carefully segregate from ourselves behind laser curtains or in metal cages. They are increasingly sophisticated devices found in a multitude of geometric configurations working in complex (compact, unstructured, dynamic, etc.) environments, often interacting with humans as well as other manipulators. I have a background that is well suited to contributing in this domain and have had the opportunity to participate in a variety of pioneering projects. As the Program Manager of a research group that averages more than $1M in funding per year, I have had the opportunity to participate in every phase of research from proposal writing to deployment. This experience has helped me to develop a broad technical foundation, a larger view of the research trends, and a leadership approach that allows a program to succeed in a competitive (and growing) area....

Teaching Philosophy

In 10+ years of teaching, my philosophy has evolved from a list of lofty ideals - and implementation guesswork - to a set of pragmatic principles that have led to success in the classroom. A combination of positive feedback from students (I have averaged a 4.38/5 instructor rating on my student evaluations at UT.) and constructive criticism from my peers has contributed to my growth as an instructor. In addition, my enjoyment for teaching has encouraged me to accept a wide variety of teaching experiences, ranging from the high school Physics classroom where I taught 3 AP students to a semester at the University of Texas at Austin where I taught over 250 prospective engineers. My broad interest in the sciences has also led me to teach diverse topics - from high school Earth Science to Advanced Robot Dynamics for UT graduate students. Along the way, I cultivated a teaching philosophy based on the core principles detailed below - principles that guide me each semester as I strive to help students understand, communicate, evaluate, apply, and make positive scientific contributions and technical developments in their communities...

Research Background

My research background has given me a skill set that impacts a variety of robotic and related domains. My graduate research focused on real-time, task-based resource allocation for redundancy resolution of high Degree-of-Freedom (DOF) manipulators. The objective was to develop a general decision making strategy for modular, reconfigurable systems where tasks were not predetermined. To describe the manipulator's environmental interactions, I considered multiple task representations including constraint-based, impedance, and ellipsoidal models. Additionally, I implemented and tested over 30 criteria derived from kinematic, dynamic, compliance, and obstacle models to evaluate and improve performance.

I developed the critical boundaries concept to determine which criteria were relevant in a given operational state. The resulting algorithm selected (and weighed) a subset of criteria used to determine locally optimal joint-space configurations. For example, if a system is at payload capacity, I include a minimize joint torque criterion. I then explored a variety of potentially real-time optimization techniques, including gradient projection and direct search methods. Finally, I simulated the developed algorithms - known as a Decision Making System - on a 10-DOF chain, completing a set of random and dexterously challenging activities.
