ORAU’s Director of Human Resources Mae Mosley, D.B.A., has been a staple of employee relations at ORAU for more than six years. In this role, she manages talent management services, talent development and performance, employee relations and diversity; and the impossible task of remembering almost every employee’s name. 

As her career has evolved to executive advisor on employee diversity, employee relations and employee compliance, a career in human resources seems like it has always been a natural fit. Mosley did not enter the workforce intending to become the HR guru she is today, though. When asked why she chose to work for a STEM-related company she explained that her roots began in a STEM field.

“It may surprise some to learn that my early career began with a degree in Industrial Engineering. I worked for a major manufacturing company in Wisconsin, but I gravitated to human resources because I had excellent people skills and genuinely enjoyed being around everyone. Even though I am not currently in a STEM position, it has always been a passion for me. Whenever possible, I sneak a few Industrial Engineering techniques into the HR world.”

As an HR professional, Mosley uses the problem-solving skills of an engineer to solve exciting, new challenges each day.

“I have a very challenging job at ORAU. No day is ever the same as the one before it. Employee relations is a field of practice within the human resources discipline and a great deal of my role requires me to engage with people and reach resolutions to issues and concerns.”

But Mosley is up for the challenge because, to her, the people make the job worthwhile.

“I happen to enjoy what I do. The key to being successful at employee relations is having a genuine concern for people and ensuring adherence to consistent and unbiased practices. Whenever I complained about getting out of this line of work, my mentor would say, ‘If not you, then who?’ As long as I believe I am the best at it, I’ll keep doing it.”

Mosley draws her infectious enthusiasm for people from role models such as Mary McLeod Bethune, Mary Church Terrell, Maya Angelou and Nelson Mandela, but most of all, her inspiration comes from her mother.

“My greatest role model was my mom, Mrs. Earnestine Richmond. She was a true leader who set the example for her family and everyone around her. She was never short on words or wisdom. It is very rare that one can grow up exposed to someone like my mom. She was courageous, consistent and persistent. She taught us there is always something to aspire for, so why not go for it? Perhaps that is why I pursued my doctoral degree at this stage of my life. It was something to aspire for, so why not go for it?”

In the spring of 2019, Mosley successfully defended her oral dissertation and earned her doctoral degree in business administration from Lincoln Memorial University Tennessee.

In addition to her current position at ORAU, Mosley owns MDM HR Consulting, a human resources consulting and training firm. She holds multiple certifications, two associate degrees, a bachelor’s degree in business and management communication and a master’s degree in business and human resources management from Concordia University Wisconsin.
