What do you love about being a scientist?
My favorite part of being a scientist is the systematic approach we employ to answer questions. Yeah, we can use a variety of techniques to get at our answers, but the process of collecting and interpreting the data must follow the same basic rules! I’d also add, that I am particularly fond of being a geoscientist because of the combination of lab and field work (the best of both worlds)!
What do you do?
I could be classified as a Paleontologist, Geochemist, and/or Paleoclimatologist. Which I choose to call myself depends on who I am talking to (obviously, I go for Paleontologist when talking to young kids for the instant cool-points)! The reason for the multitude of possible names is that I apply a variety of techniques to answer questions about the climate. In particular, my research focuses on the timing and nature of climatic changes in Earth’s history and their relationship to how carbon is stored and distributed on the Earth (e.g. in the atmosphere as CO2 or stored in rocks as fossil fuels).
What are your data, and how do you obtain them?
I use fossils and their geochemical signals to understand the climate in the geologic past. The fossils I work with most are conodont elements (small tooth-like structures that make up the feeding apparatus of a marine eel-like organism). These fossils are composed of the mineral apatite which acts as a good record for the geochemistry of the water in which the conodont animal lived. From these tooth-like structures, I measure the oxygen isotopic ratios (the relative abundance of 18O relative to 16O). The oxygen isotopic ratio is dependent (in part) on the temperature of the water. By documenting changes in the oxygen isotopic ratio through time, I can infer changes in water temperature through time.
I also work with carbon isotopic ratios (the relative abundance of 13C to 12C) in marine limestones. These values can be used to reconstruct the distribution of carbon on the Earth’s surface. By looking at changes in the carbon isotopic value through time, I can infer changes in the global carbon cycle and therefore atmospheric carbon dioxide (CO2) levels.
How does your research contribute to the understanding of climate change or to the betterment of society in general?
In addition to my scientific research I also teach undergraduate students at SUNY Potsdam. I always make sure my research informs how and what I teach. This is especially true for the Climate Change course I teach. That course focuses on how scientists know what they know and what types of evidence informs our understanding about climate. My hope for students completing that course is that they will come out of it with the knowledge and background to understand climate change.
What advice do you have for aspiring scientists?
Make sure you do what you love. Your job should be fun. That doesn’t mean every aspect of it will be a blast, many of the things I do can be tedious, but there is something very satisfying about setting out to solve a problem, collecting the data, and interpreting the data. For students interested in pursuing graduate education, the most important advice I can give is to make sure you can work with your advisor. I had a great advisor and it made graduate school a great experience.

I hate to say it, but that first photo reveals the locality they’re collecting data at. While conodonts aren’t technically vertebrates, they are still very valuable. Poachers are a real threat. Could you crop the photo to at least exclude the horizon? Maybe focus on the paleontologists’ faces/torsos?
Hi, Bob – This is the photo that Dr. Quinton gave us for her post to showcase her and her research. The location is only referred to by the state and the formation – both of which are quite expansive. The same can be said about many images online referring to fossils or rocks. At Time Scavengers, we know the educational value of all fossil finds, especially microfossils as several members of our team actively study them. Feel free to email us through our contact form if you want to discuss this further. Best, Jen
