Interview with a Park Scientist

Interview with a Park Scientist

To switch things up this week, I thought I would interview someone working for the National Park Service I think is a great person for who they are and what they do for Yosemite National Park. Though I do not directly report to her, she is someone I feel like I can easily talk to about anything regarding my internship or work at the park this summer! Rachel is considered the black bear expert of the park, though I could argue she’s the expert for the entire state!

Name, title:

Dr. Rachel Mazur, Branch Chief of Wildlife, Visitor Use, and Social Science


B.S. (Penn State), M.S. (SUNY College of Forestry), M.P.A. (Syracuse University), Ph.D. (U.C. Davis)

How long have you been working for the National Park Service?

I started with the National Park Service as an SCA intern in 1989.

What brought you to the Park Service and Yosemite in particular?

The former division chief of Resources Management and Science recruited to come to Yosemite for a detail. I enjoyed it and ended up applying for the job.

What is the coolest part about your work/research?

The coolest part of my work is getting to dabble in a broad range of wildlife restoration and research projects since the Yosemite wildlife program is very large and diverse.

Share a defining moment in your career.

A defining moment in my career came when I sat in a giant sequoia grove and watched two bear cubs nurse. It was absolutely stunning and reminded me to slow down and observe.

If you could begin a research project on any species, problem, or topic, what would it be?

I actually am working on a pet project outside of work. My friend Olotumi Laizer, a Maasai warrior from Tanzania, now lives and works at Yosemite. How and why did he move and what can we learn from each culture? That is the subject of a book we are writing.

Growing up, did you see yourself becoming a scientist?

When I was a kid, I wanted to work at the local five-and-dime variety store. Later, I wanted to be a landscape architect. Then I wanted to be a wildlife biologist. When my kids were little, I wanted to be a stay-at-home-mom. Now, I want to be a writer.

What do you like to do on your off time?

On my off time, I play with my kids. They are the center of my universe. Often, that means camping, swimming, or taking them to participate in wildlife projects.

(Mosaics in Science is an internship program that provides youth that are under-represented in the natural resource science career fields with science work experience with the National Park Service. 2014 data revealed that the National Park Service workforce is 18% racially diverse (African Americans, Hispanics, Native Americans, Asians, Pacific Islanders, others). In STEM fields, this number drops down to 3%, compared to the national average of 6%). Why is it important to have programs like Mosaics in Science that promote inclusion, diversity, and equity in the science field? 

Mosaics in Science is designed to let people know about jobs with the National Park Service. Bringing in a diversity of people is critical to our success because with a diversity of people comes a diversity of ideas, experiences, skills, and ways of doing things that continually improve the way we achieve our mission. I love interns, partly because I spent my first two years as an intern.
