Lead Data Scientist at MITRE

Using my skills from both school and previous jobs– Discrete Event Simulation, System Dynamics,

Agent Based Modeling– Data Analysis and Processing– Statistical Analysis and

Systems Engineering Techniques– Data Visualization

Problems I help solve:– How can we use math and statistics to better

serve Veterans waiting for benefits?– Can simulations help us to plan how clean up

America’s nuclear waste more safely, effectively, and within a reasonable cost?

– How can we make use of data and models to run our own organization more effectively?

– Can predictive analytics be used to help increase child welfare?
