Berkeley Air team


David Pennise, Ph.D. (Technical Director, Co-Founder)

David co-founded and helped grow Berkeley Air, in line with his commitment to create a sustainable, healthy world. He manages the technical activities of the company and leads the service delivery team in providing monitoring and evaluation services and tools. He has conducted and managed air pollution research, carbon monitoring studies, and training workshops related to household energy, health, and climate throughout the developing world. His peer-reviewed publications have focused on household air pollution monitoring, modeling, and study design; fuel use; greenhouse gas emissions monitoring and methods; and atmospheric chemistry.

David holds a Ph.D. in Environmental Health Sciences from the University of California, Berkeley, an M.S. in Environmental Sciences from the University of North Carolina at Chapel Hill, and a B.S. in Chemistry from Rensselaer Polytechnic Institute.


Dana Charron, M.B.A. (Managing Director, Co-Founder)

Dana brings a passion for tackling environmental problems at home and as far away as Antarctica. She has managed projects and founded new initiatives in both the private and non-profit sectors, including the Household Energy and Health program at the Center for Entrepreneurship in International Health and Development (CEIHD) and the Woodwise Consumer Initiative at Co-op America. Through more than 15 years of experience, she has developed expertise in household energy, forest products, environmental analysis, and entrepreneurial and sustainable business practices. Dana has particular interests in 1) using scientific approaches to catalyze social change; 2) building entrepreneurial organizations; and 3) aligning sustainability with the profit motive to achieve success.

Her skills include strategic planning, market research, writing and editing, group facilitation, stakeholder engagement, budgeting, and employee and contractor management. She has cross-cultural business experience in East Africa, China, Australia/New Zealand and Europe, and is fluent in French and German. She holds a Masters in Business Administration from the University of California at Berkeley and a B.A. from Wellesley College.


Michael Johnson, Ph.D (Senior Scientist)

Michael has worked extensively on field-based methodologies to quantify greenhouse gas reductions achieved by improved stove projects, with an emphasis on monitoring instrumentation and study design. He has conducted stove emissions monitoring in Mexico, El Salvador, Kenya, and India, and worked on several air pollution studies, including exposure assessments of biomass stove users, wildland firefighters, and public transport commuters. His peer review publications include four on greenhouse gas emissions and stove performance testing, and several others on indoor air pollution, exposure assessment, and characterization of monitoring instruments. Michael has a Ph.D. in Environmental Health, Science, and Policy from the University of California, Irvine, an M.S. in Science Education from Oregon State University and a B.A. in Physics from Colorado College.


Charity Garland, M.S. (Field Sciences Analyst)

Charity’s career has been driven by a long-time awareness and concern for environmental and health issues. She received her B.S. in Environmental Chemistry at University of California, Santa Cruz. Upon graduating from UCSC, Charity worked at Pacific Northwest National Labs, where her interest in air quality emerged while involved in an investigation of the atmospheric transport of pollutants across the Puget Sound. She built on this interest and experience during her studies at University of California, Berkeley, where she completed her M.S. in Atmospheric Analytical Chemistry while conducting field studies related to convective storm chemistry and space-based greenhouse gas measurements aboard NASA research aircrafts over the United States. Upon completing her M.S., Charity joined the Berkeley Air team where she has applied her analytical expertise to cookstove related field studies in Vietnam, India, and Benin, studying cookstove emissions and training local field teams in fuel consumption study techniques.


Peter Pagnucco, B.A. (Project Accountant)

Peter has managed finances for small to medium-sized private companies and non-profit organizations that seek to improve the health of our communities both near and far. Prior to joining Berkeley Air in 2012, he was involved with affordable housing/urban design and sports nutrition companies. Peter holds a B.A. in Philosophy from Tufts University and is a graduate of the National Outdoor Leadership School (NOLS). A New York native, he’s called the Bay Area home since 1991 and has enjoyed the music scene, bountiful outdoor opportunities and diversity of its peoples.


Dr. Nap Hosang, M.D., M.B.A., M.P.H. (Co-Founder)

Nap is a Lecturer in the Maternal and Child Health Program at the School of Public Health, UC Berkeley. He is also Chair of the Interdisciplinary MPH Program and a faculty sponsor for the School’s Health Environment and Development program and the International Health Specialty Area.

Before joining the Berkeley faculty in 1989, Dr. Hosang was on the medical faculty at the University of the West Indies, Jamaica. He is a practicing obstetrician (Kaiser-Permanente) with special interests in perinatal outcomes, breastfeeding and uterine fibroids domestically, and the management of maternal and child health services in developing countries. His teaching emphasizes leadership development and management training in public health education.

Dr. Hosang is a founding member of the Bay Area International Health Interest Group, a UC Berkeley, UC Davis, UC San Francisco, and Stanford collaborative that promotes educational activities for students with interests in Global Health. He also co-founded the Center for Entrepreneurship in International Health and Development (CEIHD).
