I am a controls engineer who greatly enjoys working with small aircraft and developing algorithms that enhance their autonomous capabilities. In recent years I have gained considerable experience in the areas of embedded software development for autopilots, state estimation using IMU, airspeed, and optical flow sensors, and attitude control of small multi-rotor and fixed-wing aircraft using both quaternions and Euler angles. More recently, I have been able to make use of my doctoral research techniques in industry, where I originally employed stochastic optimal control to perform robust, optimal control and coordination of small, fixed-wing unmanned aerial vehicles (UAVs) for vision-based target tracking. My general interests include optimization-based control of autonomous vehicles, state estimation, regression, and embedded software development for autopilots.

Postdoctoral ResearcherUc Santa Barbara Sep 2014 - Jul 2015Santa Barbara, Ca, UsStudied the problem of using multiple continuously rotating quadcopters equipped with directional antennas to perform localization and tracking of a moving radio frequency (RF) source. Employed a particle filter that utilizes a motion model inspired by the tumble and run behavior of bacteria and also directly incorporates the directional received signal strength (RSS) measurements of the radio signal emitted by the RF source, which is made possible by learning the RSS measurement likelihood function offline. Wrote Python scripts and assembled quadcopters to perform live flight experiments that verify the efficacy of the proposed approach, which achieves an average position estimation error on par with that of commodity GPS receivers. -
Graduate Student ResearcherUc Santa Barbara Sep 2009 - Sep 2014Santa Barbara, Ca, UsStudied the problem of visually tracking and estimating the position of a randomly moving ground target with a small, fixed-wing Unmanned Aerial Vehicle (UAV) equipped with a gimbaled camera. Used probabilistic planning techniques to generate control policies that are robust to unpredictable target motion and unmodeled system dynamics while enabling the following autonomous flight behaviors: 1. One UAV with a limited sensing region to maintain visibility and proximity to the ground target 2. Multiple UAVs to flock together in order to distribute the sensing task amongst group members 3. Two UAVs to optimally coordinate in order to gather the best joint vision-based measurements of the ground target’s position.Derived a policy generation technique along with an essential robust regression scheme to circumvent the computational challenges associated with the dynamic programming solution to the stochastic optimal coordination of two UAVs, which is a moderate dimensional Markov Decision Process. Validated control policies through either Monte Carlo simulations or live flight experiments.

Undergraduate Student ResearcherNasa Dryden Flight Research Center May 2007 - Jul 2007Implemented a system to monitor and characterize the current draw behavior of model aircraft servos aboard a small rotary-winged UAV in order to verify the structural integrity of the aircraft servos and linkages. Designed a circuit board that monitors the current draw using sense resistors in conjunction with an embedded microprocessor.

Undergraduate Student ResearcherNasa Dryden Flight Research Center May 2006 - Jul 2006Designed a global range data acquisition system for the scientific missions of small UAVs. Utilized a PC104 CPU module to acquire sensor data from a custom-designed printed circuit board and communicate over the horizon using an Iridium modem. Implemented the design using Montavista Linux, Embedded C, and OrCAD.
