As the newest Queen’s National Scholar, Diane Orihel is settling in at the university.

The QNS in Aquatic Ecotoxicology, Dr. Orihel’s research looks into the fate and effects of contaminants in the environment. Specializing in freshwater ecosystems, she uses an ecosystem approach to ecotoxicology.

“Traditionally, toxicology has focused on short-term assessments of the direct toxicity of a chemical on a model organism,” she explains. “Such experiments are informative but that’s not what actually happens in the real world. The real world is complex – contaminants released from smoke stacks or sewage outfalls often change as they enter and move through aquatic ecosystems, and affect not only individual plants and animals, but whole food webs. By using an ecosystem-based approach to ecotoxicology, I unravel the intricacies of how chemicals behave in our lakes and wetlands and the impacts they have on everything from plankton to fish.”  

As the QNS, Dr. Orihel is jointly-appointed to the School of Environmental Studies and Department of Biology. It’s an ideal set up she explains and was one of the biggest draws for coming to Queen’s. Her work, she says, while grounded in science, is always framed in terms of environmental policy.

“All of my research starts with the question: what is the policy need and what are the scientific  data required to address that policy need?” she says. “Being able to have a foot in the Department of Biology and a foot in the School of Environmental Studies is a very good match for me because that’s what I do. For me, science doesn’t stop at the scientific publication. I work hard to bring my science to the public and to engage decision makers, so that together we can make strides toward solving our most pressing environmental problems. ”

For example, her research has already contributed to: linking atmospheric mercury deposition and methylmercury concentrations in fish; understanding nutrient recycling and toxic algal blooms in freshwater lakes; and probing the degradation of a common flame retardant in the natural environment.

Another advantage Queen’s offered Dr. Orihel is its proximity to the Queen’s University Biological Station (QUBS). A mere 45-minute drive north and she is immersed in her research environment. At the same time Dr. Orihel is excited to be working with some of the leading experts in water issues, in Canada and around the world, at Queen’s.

I've spent more time than many will believe [making microscopic observations], but I've done them with joy, and I've taken no notice those who have said why take so much trouble and what good is it?

Antonie van Leeuwenhoek

It's a parts list... If I gave you the parts list for the Boeing 777 and it had 100,000 parts, I don't think you could screw it together and you certainly wouldn't understand why it flew

Eric Lander

What is true for E. coli is also true for the elephant

Jacques Monod

The world becomes full of organisms that have what it takes to become ancestors. That, in a sentence, is Darwinism

Richard Dawkins

Shall we conjecture that one and the same kind of living filaments is and has been the cause of all organic life?

Erasmus Darwin

Nature proceeds little by little from things lifeless to animal life in such a way that it's impossible to determine the line of demarcation


Cells let us walk, talk, think, make love, and realize the bath water is cold

Lorraine Lee Cudmore

In the distant future I see open fields for far more important researches. Psychology will be based on a new foundation, that of the necessary acquirement of each mental power and capacity by gradation. Light will be thrown on the origin of man and his history

Charles Darwin

It is my belief that the basic knowledge that we're providing to the world will have a profound impact on the human condition and the treatments for disease and our view of our place on the biological continuum

J. Craig Venter

Imagine a house coming together spontaneously from all the information contained in the bricks: that is how animal bodies are made

Neil Shubin

A grain in the balance will determine which individual shall live and which shall die - which variety or species shall increase in number, and which shall decrease, or finally become extinct

Charles Darwin

The stuff of life turned out to be not a quivering, glowing, wondrous gel but a contraption of tiny jigs, springs, hinges, rods, sheets, magnets, zippers, and trapdoors, assembled by a data tape whose information is copied, downloaded and scanned

Steven Pinker

We wish to discuss a structure for the salt of deoxyribose nucleic acid. (D.N.A.). This structure has novel features which are of considerable biologic interest

Rosalind Franklin

We are biology. We are reminded of this at the beginning and the end, at birth and at death. In between we do what we can to forget

Mary Roach

The systems approach to biology will be the dominant theme in medicine

Leroy Hood

I've always been interested in animal behavior, and I keep reading about it because it's so surprising all the time - so many things are happening around us that we neglect to look at. Part of the passion I have for biology is based on this wonderment"

Isabella Rossellini

Because all of biology is connected, one can often make a breakthrough with an organism that exaggerates a particular phenomenon, and later explore the generality

Thomas Cech

Nothing in Biology makes sense except in the light of evolution

Theodosius Dobzhansky

Biology is now bigger than physics, as measured by the size of budgets, by the size of the workforce, or by the output of major discoveries; and biology is likely to remain the biggest part of science through the twenty-first century

- Freeman Dyson

Nothing can be more incorrect than the assumption one sometimes meets with, that physics has one method, chemistry another, and biology a third

- Thomas Huxley
