Service Area Leads

John Eyraud

In college I began applying my passion for data to the field of economics. This led to a career focused on helping federal agencies understand the economic implications, costs, and benefits of major policies and regulations they develop. I feel fortunate to have had so many opportunities to support effective and affordable regulations throughout my career at ERG.

Calvin Franz

At ERG, our economic projects often take us into uncharted territory where standard, regularly collected data are few or unavailable and the analytic path to answer our client’s questions is not obvious. This is exactly where I like to be! I find it deeply satisfying to explore new territory, address unique challenges, and use my expertise and creativity to develop approaches that provide meaningful, defensible results.

Naida Gavrelis

I am passionate about doing all we can to protect people’s health and well-being and the environment in which we live. I have devoted my career to addressing health risks encountered in our communities and workplaces. I strive to solve problems using common sense and sound science.

Arlene Levin

I was thrilled when I started working for ERG and found that I could apply my passion for environmental and occupational health by working for government agencies that promote and protect the health of individuals, workers, and the environment. This nexus has allowed me to pursue incredibly interesting work across myriad health-related topics and to help my clients plan, develop, and implement successful programs and initiatives.

Lou Nadeau

Agencies tend to manage what can be readily measured, but with a large toolbox of analytical and data collection techniques and some creativity, so much more is possible! I am proud and inspired to apply my program evaluation and economic valuation expertise to help agencies manage better—by providing them with valid, reliable data to enhance decision-making and by effectively communicating this information to my clients, their stakeholders, and upper management.

Valerie Overton

In today’s world, pioneering innovative solutions requires collaboration between subject experts, information technologists, and communicators. I’m proud to be part of an organization that is built around that concept and has empowered me to propose forward-looking ideas and develop cutting-edge solutions to meet our clients’ present and future needs.

Aylin Sertkaya

Economic analysis has been my field ever since my early 20s, when I first discovered its complexities, potential, and power. At ERG, I’ve had the good fortune to work with great colleagues and clients to research issues and develop solutions for a wide variety of highly consequential public health questions. It has been a consistent joy to do work that is not only impactful but also a path of continuous learning and deepening.

John Wilhelmi

Clean air, safe workplaces, a stable climate for generations to follow—these are just some of the ideals that motivate my daily work. I strive to bring the best available science to our nation’s current and emerging environmental health and occupational safety issues. Solutions are important to me. Whether proposing air pollution controls to reduce community air toxics exposures or identifying engineering controls to address occupational hazards, I seek common sense and actionable solutions that benefit the health and safety of our population and workforce.
