I develop, evaluate, and apply exposure assessment methods to gain a better understanding of occupational and non-occupational exposures to chemical, biological and radiological agents. I am a certified industrial hygienist (CIH) with 20+ years of experience in professional practice that informs my research, teaching and service.

I especially enjoy leading and working with interdisciplinary teams in answering complex questions involving the anticipation, recognition, evaluation, and control of health hazards.

Since 2021, I have served as deputy director of the Midwest Center for Occupational Health and Safety, the NIOSH-funded education and research center.

Awards & Recognition

  • Member, Delta Omega Honorary Society in Public Health
  • Fellow, American Industrial Hygiene Association, 2014

Professional Associations

  • Past Board Chair, American Conference of Governmental Industrial Hygienists
  • Member, American Industrial Hygiene Association
  • Member, International Society of Exposure Science
  • Diplomat, American Board of Industrial Hygiene


Research Methods/Techniques

In my research, I employ a range of laboratory and field empirical and statistical methods to identify inputs to accurate decision making that will lead to more accurate exposure estimates. I generate models and model inputs that are applied to unprecedented scenarios, such as the Deep Water Horizon explosion and disaster.

Academic Interests and Focus

My academic interests and teaching focus include the anticipation, recognition, evaluation, and control of health hazards, particularly work related health hazards and associated exposures. I bring these interests, research, and practical skills to the courses that I teach.

Teaching Areas

Occupational health, industrial hygiene, exposure science


I teach courses in occupational health and safety, exposure science and industrial hygiene, including PubH 6150: Interdisciplinary Evaluation of Occupational Health and Safety Field Problems; PubH 6172: Industrial Hygiene Applications; and PubH 6193: Advanced Topics in Human Exposure Science. I strive to build a safe environment that encourages my students to make inquiries, identify best practices, and apply them. I use interactive teaching methods, such as hands-on exercises and case studies. I apply my own research and practice experiences to help cultivate the next generation of outstanding industrial hygienists. I also use my industry network to create opportunities for students to gain exposure to, and experience in, diverse work environments to reinforce classroom learning.

Community Engagement

My service roles provide excellent opportunities to collaborate with others and magnify the impact of our work through shared learning. My work is largely research-to-practice oriented and relies on input from industry partners, which highlights knowledge gaps requiring more fundamental research and continues to connect academia to industry.

I co-founded and am director of the University of Minnesota Exposure Science and Sustainability Institute, which delivers research and training to our industry partners.
