Magna Cum Laude

Professional 2000 - Present US Army Ben t Laboratories Watervliet, NY

Experience Mechanical Engineer

Performed advanced engineering work, in the areas of vibration suppression and

advanced composite structures, to support research and development

efforts on large caliber gun systems. In charge of the Advanced

Composites Launcher Laboratory and considered to be Benet s resident

expert on advanced composite materials. This involves contributing, to

some degree, to all programs using advanced composites at Benet.

Responsible for simulated proof testing of mortar baseplates. This involved

determining the test methodologies and hardware for applying the

simulated firing load and validating the test output. Currently baseplates

for all mortar systems are undergoing simulated proof testing instead of

live fire proofing. In the first two years alone this effort saved over two-

million dollars.

Leader of the Composites Thrust of the Durable Gun Barrels MTO. This thrust

was responsible for developing a robust, cost effective, production

capable system for manufacturing composite gun barrels with high-

tension overwraps. Duties included helping to get the MTO funded by

briefing at various levels, determining which materials would be used,

procuring the necessary equipment, manufacturing and evaluating stub

tubes of various configurations, and firing a full scale gun tube with a

high tension overwrap. The technology being developed by the MTO

was used on the SDD program of FCS-MCS. This work led to receiving

the 2008 US Army Research and Development Achievement Award.

Responsible for manufacturing the composite containment structure for the the

electromagnetic railgun launcher program. This included overseeing the

manufacture of stub tubes and full size launchers in-house as well as

component material selection and inputs to the cross-sectional design of

the launcher. This program is utilized the wind in tension process

developed by the Durable Gun Barrels MTO. Two meter and four meter

railguns were manufactured and successfully test fired.

Responsible for the composite tube support for FCS MRAAS. Besides standard

design and fabrication work this also included selection of manufacturing

process and selection / procurement of the necessary materials. The tube

support was successfully fired in Summer 2003 and was the first major

composite component manufactured at Benet in over five years. This

work led to receiving the 2004 US Army Research and Development

Achievement Award.

Responsible for the non-destructive evaluation (NDE) of all composite structures

at Benet. This includes performing/overseeing acoustic emission, modal

impact and ultrasonic inspection testing of structures ranging from

composite tube supports to stub and full size composite overwrapped gun

tubes.

Served as acting Unit Supervisor for the Modeling and Simulation Unit of the

Technology Division from Oct 2003 to Jan 2004. The Modeling Unit is a

20-person team that also includes two fatigue labs and a firing range.

Some of the activities during this time frame included employee

evaluations, workload adjustments and acquiring of new personnel.

1995 - 2000 Rensselaer Polytechnic Institute Troy, NY

Researcher

Experimentally validated a method to predict the response of plate structures to

excitation by piezoelectric actuators. Extended the existing method to

include composite materials and various boundary conditions. Designed

and maintained the lab s web site.

1992 - 1999 USAF Palace Knight Program

Mechanical Engineer

Part of the USAF Palace Knight Program to increase the number of Ph.D.s in the

Air Force s research labs. Involved time at both Rensselaer and USAF

Research Lab (AFRL/VSDV).

May 1999 Rensselaer Polytechnic Institute Troy, NY

Consulting Engineer

Consulted with the Sailplane Project to experimentally determine the natural

frequencies of the T-tail of the RP-3 sailplane.

1997 - 1999 UTECH Products, Inc Albany, NY

Computer Consultant

Provided consulting services as needed in the research and development

department of a medical software and products company.

Maintained the existing NT and Novell networks. Interfaced the NT domains and

the Novell network. Designed and maintained the company web sites.

Wrote install routines and help files for the company's software.

Performed Year 2000 compliance testing of the software. Assembled

specialized PC s for customers and installed and configured them on site

with UTECH s software. Interfaced the PC's with endoscopy systems in

procedure rooms. Ran the company s booth at the 1998 SGNA Trade

Show. Handled tech support calls from customers.

Appointed acting Director of R&D, after the previous Director of R&D left in

Andrew Littlefield -3-

February 1999.

1996 - 1998 Smart Sites, Inc. Rutland, VT

Web Site Developer

Designed and maintained web sites for customers. Trained customers in

maintaining their own web sites. Backup Administrator for the

company s server.

1996 Troy, NY

Test Engineer

Contributed in the fabrication and testing of a composite speed skiing helmet for a

member of the US Speed Skiing Team.

1994 - 1995 USAF Phillips Lab Edwards AFB, CA

Mechanical Engineer

Worked at the Applied Composites Branch of the Space & Missiles Technology

Directorate of Phillips Lab (OL-AC PL/VTSC).

Project Officer for the branch s participation in the MSTI-2 and 3 projects.

Managed resources to produce an all-composite antennae mast.

Point of contact for the Low Cost Composite Space Structure project. Performed

design and analysis for both the breadboard and flight boom. Oversaw

fabrication of the breadboard boom.

Developed a way of fabricating isogrid cylinders. Received a team award for this

activity.

Developed, instituted, and maintained an inventory database program for the

composites lab.

Recognized as the branch s computer hardware, software, and CAD expert. Set up

and maintained a Windows for Workgroups network over the existing

Novell network.

1992 - 1994 Rensselaer Polytechnic Institute Troy, NY

Researcher

Conducted research to support Master s project. Designed and fabricated

composite I-beams with embedded shape memory alloy actuators.

1990 - 1992 Rensselaer Sailplane Project (RP-3) Troy, NY

Fuselage Group Leader

Responsible for fabrication and installation of composite structures for the

fuselage. Performed the conceptual design for the landing gear. Various

types of composite materials including graphite, Kevlar, and fiberglass

were used to fabricate the parts. Fabrication methods included room

temperature curing wet lay-ups and prepreg lay-ups in an autoclave.

1991 Rensselaer Polytechnic Institute Troy, NY

Design Engineer

Developed a vacuum forming process for the creation of prototype composite parts

and final molds, from a CAD model. Process reduces the time required

for making a master mold from several weeks or months to a day or two.
