What in your life drew you to your current field of study?

A series of accidents...

Throughout my career, I have had the great fortune to have many incredible mentors, both men and women, who have opened doors and shown me the way to a world of discovery. The first such accidental guidance came from a high school teacher in Mexico, who disrupted (without knowing) my intentional path to art school by sharing his passion for science. As I set to follow this newfound path, I initially thought I wanted to be biologist until I met the man who would eventually become my graduate advisor and who lead me through the discovery of environmental geochemistry research. In a side-conversation after class, early in my senior year, he invited me to participate in an oceanographic research cruise on the St. Lawrence Estuary (Canada). Following the collection of a large number of water and sediment sampled, he invited to work in the lab as an undergraduate research scholar for the rest of the year. With a published peer-reviewed publication by the time I graduated, I was hooked. What then followed was years of fieldwork in remote locations (Canadian Tundra/Taiga, Greenland, North Atlantic, boreal and tropical lakes, the Arctic) and in the lab developing the necessary expertise to unveil untold stories of human impact and global change in multiple environments.

I find it particularly amazing that from a few millionth of a gram of a substance you detected in deep sediments, you could reconstruct the history of contaminant transport or natural vegetation shifts in an aquatic system, or the health history of inhabitants in surrounding metropolis. Finding the right tool, and looking through the right magnifying glass, is what really drives a lot of what I do. I think that there are still so many conundrums in trying to explain the natural world around us that we don't run a risk of getting bored any time soon.

Being able to communicate the mysteries of nature to future scientists, educators, policy makers, and the general public gives this activity even more relevance. However, as I evolved through my career and particularly my leadership experience, I have recognized the need for building interconnections across all fields of research and education, to create deeply meaningful knowledge and better-prepared global citizens. Decades later, I find ways to reunite my initial attraction for art and humanities with my long-standing love for science and technology. The beauty of academia is that is it a place where knowledge is constantly created, accepted norms tested and challenged, and creativity valued at the highest level. I couldn’t have “stumbled” in a better place and wish to share my love of learning with generations of students.

What do you hope your students gain from studying or working with you?

Because of my administrative role, I do not formally teach classes presently. However, I still enjoy working 1:1 with graduate students (when working as advisees in a graduate program) or with student workers as professional mentees. No matter the relationship, I will always encourage students to reflect on their experience in a larger context, identify the leadership skill they are developing while at the university, and integrate diverse mode of thinking in their problem solving. Because I have benefited for years from the generosity of my mentors, I am always happy to commit time and shared experience with students.

What are you passionate about in your personal life?

Intellectual and physical challenge. Since I can remember, I have been active in sports and exploring the outdoors. My fieldwork has been a source of “adventure” for years, and it combined the physical and intellectual challenge I so love. Since I have switched to an administrative role, I have had to redirect my need for physical challenge and found an outlet in triathlon and road race competitions. What I also discovered as a result was a community of like-minded people who support each other, their surrounding community, and engage in larger conversations of health in our society. My life is richer today because of my wonderful teammates and friends with whom I share extraordinary achievements. In addition, I find that the physical challenges I face help me focus on my goals in a more intentional way.
