On 19 March 2018, a tornado hit Jacksonville State University’s campus. The tornado caused widespread damage across the entire campus and the surrounding neighborhoods. The tornado was a direct hit through the quad, library, and almost all major buildings.
The Remote Sensing Center was asked to provide post tornado damage assessment of the campus buildings. We (Tim Leopard, Chris R. Simpson, and I) flew a series of flights over the campus. We wish JSU the best; we hope these helped.
The Civil Engineering CE 260 “Surveying” instructor for the Fall of 2017 asked me to give a guest lecture and flight demonstration of UAVs for civil engineering applications. The class began with a short lecture (CE260-UAV) and then transitioned to Bryce Lawn for a demonstration flight over the University of Alabama’s old chapel building. My laboratory took the photos and created a 3D reconstruction of the building suitable for civil engineering analysis.
We concluded with an aerial class photo.
Thank you to the CE 260 class and the Civil Engineering department, especially Profs. Graettinger and Stogner.
For reference, the full raw flight video is here. The careful viewer should note that this flight was conducted in accordance with FAA regulations and University of Alabama requirements. Please don’t replicate this flight without first talking to UA compliance, UA Grounds, and the Tuscaloosa ATC tower.
Today, we learn the basics of aircraft inlet design.
This November, I was asked to provide a substitute lecture to a senior level propulsion class (AEM 408). For this lecture, I attempted to provide the basics of inlet design by discussing the relevant physics and constraints.
Inlet fan face total pressure was introduced as a way to quantify the performance of an inlet and to diagnose common issues.
The concept of boundary layer growth with the inlet’s adverse pressure gradient was reinforced from an earlier Aerodynamics I course.

At the University of Alabama, I taught the GES 554 course Partial Differential Equations from 2014-2017. The course investigated theory, classification, formulation, relevancy, analysis, and solutions of PDEs. Both analytical and computational methods were studied with a special focus on PDEs commonly seen in engineering.

In the Fall of 2016, I taught AEM 313 Aerodynamics I.
Objectives: Introduction to subsonic aerodynamics, including properties of the atmosphere; aerodynamic characteristics of airfoils, wings, and other components; lift and drag phenomena; and topics of current interest.
Required Book: Fundamentals of Aerodynamics, John Anderson, McGraw-Hill, 5th ed, 2010
We will cover subsonic and transonic topics in the textbook. Selected topics and sources supplement the text.
