Meet EPA Researcher Justin Conley, Ph.D.

Justin Conley is a postdoctoral researcher investigating the toxicity of endocrine disrupting chemicals and new approaches for water quality monitoring.  When he is not in the lab, he is busy brewing beer and exploring the outdoors.

EPA research Justine Clonley stands on top of a mountainMeet EPA Researcher Justin ConleyTell us about your background.

I grew up in eastern Kentucky on the Ohio River in a fairly industrial part of the state. For undergrad I went to a really small college in western North Carolina called Warren Wilson College. I was an environmental studies major pretty much from the beginning and was formally introduced to environmental toxicology through my undergraduate research project. After undergrad I worked a bunch of seasonal jobs, like field biology and environmental education, and I travelled for a while. I went back to school and got my M.S. in environmental science at the University of Tennessee at Chattanooga where I studied pharmaceutical residues in river water. From there, I continued on the path of studying chemicals in the environment. I moved to Raleigh and got my Ph.D. in environmental toxicology at NC State studying the movement and toxicity of selenium in aquatic food webs.  After I finished, I came here to EPA as a postdoc where I have been focusing on endocrine disruption and water quality monitoring.

When did you first know you wanted to be a scientist?

I was always interested in the natural world as a kid, but I took more classes in art than in science. When it came time to go to college though, I knew I wanted to do something applied. I liked being outside so I thought I might like studying environmental science.  That led me to Warren Wilson College, which had a highly rated undergraduate environmental science program.  I had a good introduction to research there and that started me on the path I’m on now. I liked how conducting research was technical and difficult, but also rewarding to see a project through to completion.

How does your science matter?

The group I work with here at EPA does a really good job of doing research that translates well to the risk assessment side of regulatory agencies. Our work shows the adverse effects of exposure to chemicals along with their dose response relationships. This research can be used—not only by EPA, but also other regulatory agencies across the U.S., Europe, and other parts of the world—to help determine if a chemical we test should or shouldn’t be used in, for example, consumer products or agricultural settings.   

What do you like most about your research?

I like that we produce results that can help determine how chemicals are regulated and used.  I believe our efforts have a positive effect on environmental and human health.

If you could have dinner with any scientist, past or present, who would it be?  What would you ask him or her?

From an environmental science standpoint, the first name that comes to mind is Rachel Carson. She clearly had a big impact on the advancement of environmental science, particularly the study of chemicals in the environment and raising awareness of the negative aspects of some of these exposures that we created. I would just be curious about her perception of how well we are doing as a scientific and regulatory community. 

If you weren’t a scientist, what would you be doing?

I would probably be brewing beer. I do a lot of brewing as a hobby so maybe I would be running a brewpub and brewing craft beers. I love the process and have always thought it could be a fun alternative that is still science related.  Either that or something outdoors. I like to spend a lot of time outside. I’ve had seasonal jobs in the past where I’ve taken people on hiking and backpacking trips, so some sort of guide outside where I can take people around and show them pretty places would be fun.

If you could have one superpower, what would it be and why?

The first thing that comes to mind would be flying. I would love to be able to just take off—and it certainly would make my commute to work much easier.

Any advice for students considering a career in science?

I think that as you work towards being a professional scientist, you spend quite a lot of time writing and speaking. Early on in your training, try and make a dedicated effort to get public speaking experience, get comfortable with presenting, and learn how to write well. How well you are able to put your ideas out there, present them, and put them into context can have a large impact on your career. 

What do you think is our biggest scientific challenge in the next 20/50/100 years?

Ideally, we are moving towards a system where we have chemicals that are effective, but benign and do not cause adverse effects. Living in a world where chemicals are not causing unintended and detrimental impacts would be the gold standard.  The problem is that we have already created legacy chemicals that are in the environment and will be there for a very long time, if not effectively forever.

Whose work in your scientific field are you most impressed by?

There are many people who do very good work, but I would acknowledge Lou Guillette.  He had a personal impact on me and produced a very extensive and strong body of research related to reproductive toxicology and physiology.  He studied alligators primarily, but he was a really great scientist in terms of relating human and ecological health.  He was highly regarded and I have learned a lot from reading his body of work.  

You’re stranded on a desert island with a community of other survivors – what is your job?

I am the one who makes all the beer! Either that, or I like building things and I do pretty well with tools, so maybe I’m the one who builds the hut.
