A rapidly expanding Durham research company that relies mostly on government public-health contracts is adding more office space to house its growing workforce.

SciMetrika's revenue will more than double this year to $12 million, fueled mostly by contracts from the Centers for Disease Control and Prevention and other federal agencies, said CEO Jean Orelien.

The company's work includes conducting a survey of health providers' satisfaction for Medicare and Medicaid, studying the effectiveness of carbon monoxide detectors and increasing access to childhood vaccines and immunizations.

Orelien, a native of Haiti who founded the company in 2001, now wants to tap new markets helping health insurers, corporations and the U.S. military improve medical care. He projects that revenue could rise to more than $100 million within the next five years.
