STEM Women of DNREC



They are engineers, biologists, scientists and leaders at the Department of Natural Resources and Environmental Control. They are also women in STEM fields, who work in the science, technology, engineering and mathematics sectors. On February 11, as we mark International Day of Women and Girls in Science, Outdoor Delaware talked with some of DNREC’s “STEM Women” and here’s what they had to say about their work and their advice to girls and young women interested in STEM fields.


Lindsay Hall
Environmental Engineer, DNREC Division of Waste and Hazardous Substances

What are your duties at DNREC?

I am a member of the Remediation Section. My colleagues and I provide regulatory oversight of an investigation and, if warranted, remedial actions on properties with potential or confirmed hazardous substance release(s) into the environment.

Sometimes, I participate as part of a team that visits a property and collects samples of environmental media, such as soil, groundwater and surface water. For my sites, I evaluate the laboratory data generated for the samples to determine whether long-term exposure to any substances on the property will potentially pose an unacceptable risk to human health and/or the environment.

More often, I review work plans and reports submitted to DNREC by environmental consultants. For each site, based on a comprehensive evaluation of the sample data and risk calculations, I will develop a plan of remedial action establishing the steps required to mitigate the identified unacceptable exposures and provide oversight and review to confirm the successful implementation of the measures.

Why did you choose your field?

I enjoy the challenge of the practical with diverse technical and logistical problem solving. But most importantly to me is that environmental engineering affords me the opportunity to make a tangible and positive lasting impact on the world. I take pride in my contribution to protect the health and welfare of future generations so that they can safely enjoy living, working or playing in that space.

What do you love about it?

I love that each site is different and presents its own set of nuanced challenges about which to think critically and work through.

For my redevelopment sites, I’m a contributing member of the multifaceted team required for the successful completion of a construction project. I am proud of my role to ensure that human health and the environment are considered, evaluated and protected during the planning and implementation of traditional construction activities. To me, it is always fascinating to hear about the different perspectives of each business sector, municipality and governmental body with interests relevant to the project while also working with a network of professionals.

What advice do you have for young women who want to enter the field?

Take advantage of internship or job shadowing opportunities. Involvement in engineering organizations can help you to network and foster relationships with engineering professionals. Remember to have confidence in your abilities and make your voice heard. Engineering remains a very male-dominated field, but your knowledge, perspective and experience are as valid and valuable as the contributions of anyone else. Take and get comfortable in your seat at the table!


Angela Marconi
Director, DNREC Division of Air Quality

What are your duties at DNREC?

I oversee the division, which is made up of about 60 professionals. Our staff is made up of engineers, scientists, planners, technicians and support staff. Air Quality is responsible for a variety of activities including monitoring the air for pollutants, issuing alerts when we may have high levels of ozone and particulate matter, updating air quality regulations and permitting/compliance/enforcement work for emissions from all types of facilities throughout the state.

Why did you choose your field?

I chose engineering because I enjoyed math and science in high school. I chose the environmental field because of my interest in preserving our natural resources and creating a sustainable future.

What do you love about it?

I love solving (or making progress toward solving) hard problems. Many types of engineering deal with limited systems, however when working on environmental issues, the system involves many variables that interact with each other and that results in very challenging problems. It is satisfying when we are able to make progress toward improving peoples’ life experience and achieving sustainability.

What advice do you have for young women who want to enter the field?

When I chose to study engineering, people gave me advice about surviving college. But, that’s just the start.

I’d tell women to think of engineering beyond just your education. It is a way of approaching problems to find the best answer and there are many ways to apply that skill as a career.


Caitlynn Mitchell
Environmental Laboratory Scientist, DNREC Division of Water

What are your duties?

My duties include both field and laboratory work. In the field, I help to collect a variety of different samples, such as surface water, fish and the occasional sediment sample. For the fish samples, I process the fish tissue, which is then tested for chemical and toxic analyses.

Another project that I work on is the National Aquatic Resource Surveys (NARS) which entails taking measurements, evaluating and collecting samples from Delaware streams, lakes and coastal waters.

In the laboratory, I perform several chemistry and microbiology tests. In addition to this, I generate, review and analyze data produced by the chemical and biological tests that I run. Managing my time between working in the field and in the laboratory is challenging some days, especially when the weather does not want to cooperate, but I enjoy being both outdoors collecting data and samples, as well as being in the laboratory processing and testing samples.

Why did you choose this field?

I have always had a deep love and respect for the ocean as well as fresh waterbodies. After writing a paper in a college English class on Turritopsis dohrnii (the immortal jellyfish), I became fascinated by the creatures and science hidden in the ocean. So, I switched my major to marine science. In this major I learned a lot about the ocean, and fresh and brackish waterbodies. Majoring in marine sciences eventually led me to my current career field.

What do you love about it?

I love that my field requires a lot of hands-on work in addition to jobs that keep me thinking, troubleshooting and solving problems. I never get bored because there are always new things to do and to learn. For instance, like learning how to run tests to analyze the amount of silica in a waterbody or how to back up a boat trailer to launch the boat (still working to perfect this skill, but I’m determined). I also love that I get to work with such smart, helpful and talented people every day.

What advice do you have for young women who want to enter the field?

Speak up, be sure that your thoughts and observations are heard and acknowledged. Also, own up to mistakes, learn to laugh about them, then move on and work to correct them. Your mistakes will not define you, they will only help you to grow and give your coworkers something to laugh at you (I mean with you…) about.


Holly Niederriter
Mammal Biologist with the DNREC Division of Fish and Wildlife

What are your duties at DNREC?

Over my 20 years with DNREC, I have managed projects with bog turtles, diamondback terrapins, frogs, salamanders, osprey and beach-nesting birds such as piping plovers and American Oyster Catchers. At this time, my primary focus is on bats and Delmarva fox squirrels.

In my position, I propose and manage projects (and grants) for the species I am responsible for with the intent of collecting data and conducting actions to protect those species and secure their future in our state and beyond. Some examples include creating nesting habitat for diamondback terrapins and then monitoring to see if the turtles used the sites (they did), deploying acoustic detectors throughout the state to determine where bat species are most abundant and translocating Delmarva fox squirrels from hearty populations in Maryland to good, but unoccupied, habitat in Delaware with the goal of making them a common species here.

Why did you choose your field?

I love animals, spending time outdoors and I wanted to do something meaningful with my time.

What do you love about it?

I love working with and learning about wildlife (even though many of my projects do not include much hands-on work like you would get in a zoo or as a veterinarian) and working with so many passionate, intelligent, and dedicated people. I get to do a wide variety of projects, have a great deal of autonomy in my job and get a mix of field work and office work. No two days are alike in this position.

What advice do you have for young women who want to enter the field?

To try a variety of classes in college until they find the best fit, talk to people doing the jobs they think interest them and try getting summer jobs or volunteering in their field.


Alison Rogerson
Environmental Scientist, DNREC Division of Watershed Stewardship

What are your duties at DNREC?

As an environmental scientist working with wetlands, my job changes every season and every year. The program I work with is science and research-based, focused mainly on tracking how many acres of wetlands Delaware has, how healthy they are, what’s hurting them, working to improve how people understand and treat wetlands and developing new ways to help wetlands do their important jobs.

Field work is an important part of my job, mostly in the summer, which means getting muddy. It is important to take the information we collect and do something meaningful with it to help improve wetlands; writing reports, looking at maps, evaluating data and turning it into something everyone can understand and use. Education is also very important in my role, so I work at events where I talk to thousands of kids and landowners about wetlands.

Why did you choose your field?

I always loved animals and wildlife but knew I didn’t want to be a vet or work in a zoo. While searching for college majors I discovered wildlife management, which I studied for my bachelor’s degree, with a minor in Water Resources Management because I was already interested in wetlands. After working several internships and traveling, I realized I wanted to focus more on the habitat supporting wildlife rather than focusing on certain species, so I returned to school for a master’s degree in wildlife ecology and a thesis studying salt marsh bird populations in Maryland.

What do you love about it?

I love being part of the solution and going to bed knowing that I’m helping the environment and the people who benefit from the natural services it offers (like clean water, a peaceful place to kayak or healthy fish to catch). If I can help people stay connected to the natural world around them and see the benefit in small acts of natural resource stewardship, then I consider it a step forward. I also enjoy the variety of work that I do and the places I go. One day I’ll be on a boat in the Inland Bays and the next I’ll be wading up a stream off the Brandywine River. I enjoy putting in a hard day’s work in the field getting muddy or in the office being productive.

What advice do you have for young women who want to enter the field?

I would say don’t stress about figuring out exactly what you want to do. There are so many options out there and you shouldn’t feel pressured to know what suits you best right away. It’s ok to try things out and decide to go a slightly different direction. Higher education is definitely important but maybe you need to explore a few areas first so you don’t rush into the wrong thing.

I also recommend being strong in multiple areas, so you are trained with a trade and a skill. Lastly, know your worth and choose what makes you happy and satisfied. It is a difficult balance, but you can pursue your professional interests and goals while also living out your personal life. There are no limits; anything is possible if you want to make it happen.
