Professional Experience

2017/NOV - Present

In this role I am currently working on two funded research projects. The first concerns experimental research for the purpose of developing a statistical approach to analyze the behavior of aerodynamically unstable bodies during flight. The goal is to develop tools that can better inform aerodynamic simulation software when attempting to predict trajectories and attitudes of unstable bodies.

2014/JAN - 2017/NOV

Conducted experimental and computational analysis of laminar flow control devices, particularly dynamic roughness, for the purpose of projectile maneuvering, increased wing efficiency, and stall delay. This includes the study of the fundamental flow physics of distributed dynamic roughness.

2009/AUG - 2013/DEC

Proved both computationally and experimentally the ability for dynamic roughness to delay the development of a leading edge vortex on a rapidly pitching airfoil.

2007/AUG - 2009/AUG

Worked on a multidisciplinary research team which conducted testing and evaluation of inflatable structures to be used as temporary flood containment devices.

2005/AUG - 2007/AUG

Investigated the behavior of various materials under biaxial load conditions for potential use on the surface of a morphing wing.

2004/MAY - 2009/JUL

Conducted comprehensive field evaluations for research projects involving highway construction work practices and safety hazards, specifically the hazard of highway construction workers being injured or killed by construction vehicles or equipment.

Service Activities

AIAA Outreach

I have enjoyed helping organize several outreach events at STEM Nights in Monongalia and Preston County Grade Schools. We typically bring supplies to have the students build their own balsa and foam gliders. Our university chapter of AIAA volunteers their time and does a great job at these events.

SAE Reviewer

As a conference and journal reviewer I get to not only provide service to SAE International, but I also get to see the most cutting edge research being conducted first-hand.

MS Committee

I have served on several MS committees in the past, have recently graduate two great students, and am serving on one MS committee, currently.
