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.

Samantha Delapena, M.S. (Project Manager)

Samantha’s career has been driven by a long-time awareness and concern for environmental issues. She received her B.S. in Biology at San Diego State University. Upon graduating from SDSU, Samantha worked at the Global Change Research Group, where her interest in air quality emerged while involved in an investigation on carbon dioxide flux on the Arctic tundra in Barrow, Alaska. She built on this interest and experience during her studies at University of San Francisco, where she completed her M.S. in Environmental Science while conducting field studies related to the ecology of the San Francisco Bay. Upon completing her M.S., Samantha joined the Berkeley Air team where she has applied her analytical expertise to cookstove related field studies in Cambodia, Laos, China, Guatemala, Honduras, India, Nepal, Zambia, Ghana, and India studying cookstove emissions and training local field teams in fuel consumption study techniques.

Madeleine Rossanese (Fellow, Project Associate and Data Analyst)

Madeleine joined Berkeley Air full-time following her bachelor’s in Molecular and Cell Biology and Interdisciplinary Human Rights from the University of California, Berkeley. During her undergrad, she worked as a part-time Berkeley Air intern starting in May of 2016. Madeleine has completed assisted and independent research in small molecule cancer drug discovery, phenotypic and genotypic variation at the border of small mammal speciation events, the epidemiology of Sudden Oak Death in the Berkeley Hills, and protocol in private practice pediatrics. She has volunteered with anti-sex trafficking initiatives in the Bay Area and served as the UC Berkeley’s American Medical Women’s Association chapter President for two years. Her work at Berkeley Air keeps her engaged with her passion for understanding epidemiological trends in diverse populations.

Ricardo Piedrahita, Ph.D., (Senior Research Associate)

Ricardo is a senior research associate with Berkeley Air Monitoring Group, having joined in early 2017.  His primary research interests are cookstoves and household energy use in the developing world, low-cost air quality monitoring, and pollution exposure assessment and modeling.  His dissertation research was part of REACCTING, a project in Northern Ghana performing personal, microenvironmental, and regional air quality measurements as part of a cookstove intervention study.  He has lead development of improved exposure monitoring systems, including a Bluetooth-based proximity sensing system.  He received a BS in Mechanical Engineering at UC San Diego, and later an MS and Ph.D. in Mechanical Engineering at CU Boulder.  He lives in Boulder, Colorado.

Kara Fleisher (Business Manager, Project Accountant)

Kara has been Berkeley Air’s Business Manager for nearly 3 years, during which time she has distributed more than 57,000,000 cute animal videos and at least 3 podcasts about true crime or hard science fiction throughout the company. She is a Bay Area native, and holds a B.A. in Cultural Anthropology from San Francisco State University. Among many hobbies, Kara enjoys DJing, painting, karaoke, and dancing to electronic/funk/hip-hop/disco music.

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).
