Current research focuses on particles, aerosols, and droplets in air, their manipulation and the chemical transformations they undergo in the presence of electric fields, all towards a common goal of improving the environment and protecting human health. The work of my research group falls both within the natural science realm, such as understanding the natural ageing of bioaerosols in the atmosphere, as well as within the engineering realm, such as innovating and optimizing novel gas purification processes. I have taught for more than 20 years, including courses in air quality engineering, thermodynamics, heat and mass transfer, and power and energy production. I hold an S.B. degree in aeronautical and astronautical engineering from MIT and M.S. and Ph.D. degrees in mechanical engineering from University of California, Berkeley.
