OBJECTIVE

Quantitative finance and trading system research position in a high growth,

progressive, entrepreneurial enterprise that rewards innovation and can

benefit from requirements driven design synthesis.

TRADING SYSTEM DEVELOPMENT AND TRADING

National Grid, Senior Energy Trader: 2012 to present

. Developed and traded natural gas trading system.

. Analysis to support natural gas trading decisions.

Solytix Capital, Chief Strategist: 2000 to present

Developed, programmed, allocated capital and traded live the following:

. Found non-random chaotic behavior around 8-day cycle lognormal returns;

exploited cycle using price peaks and volume changes; traded system live

with real capital and returned over 50% annually for 2 years out of

sample.

. Neural-genetic algorithm techniques applied to uncovering cyclic behavior

of hedged index, sector, region and stock combinations.

. Developed system and traded cyclic behavior of volatility indexes

implemented with hedged index options.

. Applied index volatility system to individual stock and ETF implied

volatilities with hedged equity options.

. Volatility system extended to currencies.

. Index and equity arbitrage system based on co-integration relationship

between risk/reward parameters of each leg.

Online Trading, Inc., Birmingham, Michigan: 1998 to 2000

Developed, programmed and directed trading of system that:

. Filtered 6000+ stocks down to 400-600 trade candidates based on

fundamentals.

. Categorized trade candidates into industry sectors.

. Ranked sector performance relative to other sectors, intraday.

. Ranked breakouts of stocks in strongest sectors by tick.

. Directed floor traders to breakout candidates in real time.

. Floor trader risk management by monitoring return deviation and setting

trade size limits to maximize return and minimize drawdown.

Tools and Skills used to develop systems:

Artificial Intelligence, Expert Systems, Neural Networks, C++, C#, Visual

Basic, Excel, R, SQL

publication on the C5 Corvette

GENERAL MOTORS CORPORATION

Fifth Generation Corvette Synthesis/Analysis Manager: 1988-1997

Led a multi-cultural team of 50 BS, MS and PhD level synthesis/analysis

engineers responsible for the crashworthiness, durability, structural

dynamics, vehicle dynamics and fluid dynamics from competitive benchmarking

to production. Led the team to direct the design by developing vehicle

performance targets then using computational tools to determine specific

design criteria. The entirely new vehicle architecture was chosen and

refined based on this work before any hardware was built. This was the

most extensive use of synthesis/analysis techniques on a completely new

vehicle in GM. The many vehicle performance targets achieved by the first

hardware tested evidenced the success of this approach. I regularly

presented our approach to other groups in GM, industry conferences and

university lectures as an example of how to successfully set requirements

and lead design to those requirements using computer aided engineering

tools.

Some highlights of accomplishments as Corvette Synthesis/Analysis Manager:

$75M investment savings due to infeasible architecture avoidance.

Enabled very long lead tooling and development time required for

hydroformed rails by selecting architecture and final rail shape before any

hardware demonstration.

5 times stiffer body structure than previous generation at less mass

achieved in first hardware.

Front and rear crashworthiness worked at first hardware tests.

No "architecture changing" or "reinforcement adding" structure durability

problems.

80-minute body shop weld time reduction due to removal of less sensitive

welds.
