To AnnieAbout the AuthorNivaldo Tro,is a Professor of Chemistry at WestmontCollege in Santa Barbara, California, where he has been a faculty member since 1990. He received his Ph.D. in chemistry fromStanford University for work on developing and using opticaltechniques to study the adsorption and desorption of moleculesto and from surfaces in ultra high vacuum. He then went on tothe University of California at Berkeley, where he did post doctoral research on ultrafast reaction dynamics in solution. Sincecoming to Westmont, Professor Tro has been awarded grants fromthe American Chemical Society Petroleum Research Fund, fromResearch Corporation, and from the National Science Foundationto study the dynamics of various processes occurring in thin adlayer films adsorbed on dielectric surfaces. He has been honoredas Westmont's outstanding teacher of the year three times andhas also received the college's outstanding researcher of the yearaward. Professor Tro lives in Santa Barbara with his wife, Ann, and their four children, Michael, Ali, Kyle, and Kaden.In his leisure time, Professor Tro enjoys mountain biking, surfing, reading to his children, and being outdoors with hisfamily. vTro IC5 FM i-xxxv v4.0.1.indd 512/11/13 1:04 PM
