Details on Experience:
1. PhD Dissertation Research:
My PhD. skillset is currently in the area of simulating two dimensional reacting flows. My
current research focus includes, but is not limited to: counter-flow flames, co-flow combustion,
shear flow, and reactive flat plates. All simulations are currently done using laminar based codes
with highly refined grids. A major amount of effort was used in including detailed chemical
mechanisms and diffusion models. I use mainly the finite volume package, OpenFOAM, to
develop my own solvers, both compressible and incompressible. I also have limited experience
with Vulcan, and Spark-2D which were developed by NASA. I will be pursuing both codes in the
remainder of my second year of graduate school. In early November 2011, I passed my oral
comprehensive exam, and am now a PhD. Candidate.

2. Aerojet Ballistics Intern:
Aerojet is a company that mainly builds rocket motors . As a ballistics intern I participated
in numerous propellant simulation tasks. I was treated as a fully capable employee and trusted
with multiple engineering problems. During my summer I learned to fully simulate propellants for
the prediction of rocket performance. I also worked to develop a gas generator that will be used
as the ignition source for the scramjet of the University of Virginia s Hy-V flight experiment. The
development of the gas generator will be the subject of my independent senior thesis as well as
the topic of an AIAA journal publication. In the report written by my supervisor, Mark Friedlander,
he stated:
Ryan is a self starter and needs minimal instruction to proceed with an assigned task. He is
logical and thorough in his approach to problem solving. He is observant and astute. He is never
afraid to ask well thought questions.
W orking for Aerojet was an unforgettable experience. It broadened my engine ering education by
giving me valued experience in predictive simulations and numerical analysis.

3. Sounding Rocket Payload Experiment:
I served as Program Manager for a sounding rocket payload experiment that is facilitated
by The NASA Wallops Fight Facility, and is an expansion of the RockON Sounding Rocket
W orkshop. The objective of our experiment was to integrate shear sensors that use
interferometer technology into a sounding rocket utilizing the resources that the RockON
experiment had to offer. My responsibilities included organizing team meetings between my
school and other participating parties, taking the role of overall technical advisor to payload
design and integration, overseeing fiscal budgeting and funding, and making executive decisions
to assure the efficiency and success of our team. For the experiment I completed conceptual,
preliminary, and critical design reviews as well as drafted funding propo sals in combination with
overseeing the complete design of our payload.

Research Assistant at The University of Virginia s Aerospace Research Laboratory
4.
The Virginia Space Grant Consortium is a prestigious institution which appropriates funding
to exceptional students seeking to do faculty advised research for summer internships. My
accepted proposal was based on studying the aspects of program management and then
implementing what skills I learned during the school year. This experience is particularly unique,
as most engineering students rarely learn how a program is properly drafted, designed, and
executed. I started the summer with the construction of the website for the Hy-V Flight
Experiment which is now available at:
www.mae.virginia.edu/HyV
It was also essential that I study modern compressible flow, due to the fact that the program that I
managed dealt with hypersonic engines known as scramjets. I also acquired enough usage time
with the software programs: Solidworks and Matlab to become extremely proficient with each.

5. RockON Sounding Rocket Workshop
The RockON Sounding Rocket Workshop was facilitated by NASA Wallops Flight Facility.
The workshop s goal was to build and integrate a fully functional payload into an Orion sounding
rocket within a time period of one week. Through the careful guidance of those running the
workshop, my team assembled the payload circuit board with instrumentation ranging from
pressure taps to Geiger counters. The payload was then integrated and launched in the sounding
rocket. The experiment was a complete success. From this workshop I was able to obtain a
greater understanding of the sounding rocket process, familiarize myself wit h different types of
data acquisition, and receive unique mechanical instruction on payload assembly and integration.

6. Student Program Manager for the Hy-V Flight Experiment
The Hy-V Program is a scramjet flight experiment that I have been involved with for the
past two and a half years. The research opportunities that the program offers revolves around the
field of hypersonics, an area of study rarely experienced during the first year s of undergraduate
studies. In this program I have researched critical re-entry speeds of sounding rockets,
hypersonic inlet designs, modern compressible flow, and program management. Acting as
program manager for the experiment s student team required that to be able keep up with modern
day organizational tools, effectively communicate with others, and understand every technical
component each of my team members were involved with. My experience as program manager
has also created unique opportunities for me to write proposals for funding and research, present
at a mission initiation conference at NASA Wallops, and attend graduate research design reviews.
I believe that The Hy-V Program has been able to take my skills and potential to new heights; I
can now confidently interact with engineering teams, respond quickly and efficiently to
complicated questions, and effectively lead a design team to bring out its full potential.

7. Test Engineer Intern at ATK
The summer of 2007 I was brought to ATK to work specifically on the free jet testing for
4
The University of Virginia s Hy-V Flight Experiment . Here I participated in cabin installation and
shakedown for facility buildup, performed instrumentation configuration and checkouts, and
scramjet installation. The working scenarios required heavy development of my mechanical skills,
as I was constantly working with both technicians and test engineers that required quick, hands -
on involvement. I participated in a wide range of pre-test and post-test activities that became
essential to the completion of heavy tasks assigned to small groups. In the report written by my
supervisor, Richard Stone, he stated:
Ryan is reliable, enthusiastic, and thorough. He maintains focus and discipline even while
working tedious tasks for extended periods of time. He learns quickly.
W orking for ATK was an unforgettable and life changing experience. I quickly adapted to living an
independent lifestyle, while at the same time brought my full efforts forward to assist the people at
ATK.
