Tim received a BS degree in civil engineering from Loyola Marymount University (LMU) in 1967 and MS and PhD degrees in environmental engineering from Stanford University in 1971. Upon graduation from Stanford, Dr. Haug joined the LMU faculty as Assistant Professor of Civil Engineering and Environmental Sciences. He retains his association with LMU as Adjunct Professor, specializing in applied microbiology for environmental engineers and scientists.

Tim has authored over 120 publications on a variety of environmental subjects. He is author of the books Compost Engineering - Principles and Practice (1980) and The Practical Handbook of Compost Engineering (1993). He has served on the Editorial Board for BioCycle, Journal of Composting and Recycling since 1988 and on the Water Environment Federation's Editorial Advisory Board for the Biosolids Technical Bulletin. He is the 2008 recipient of the U.S. Composting Council's Rufus Chaney Award for research excellence and service to the composting industry. He became a Diplomate of the American Academy of Environmental Engineering in 2001.

Dr. Haug is currently Deputy City Engineer with the Bureau of Engineering, City of Los Angeles. He oversees 250 people who deliver the City's Wastewater Capital Improvement Program. In this role, he has worked with teams of people who stopped ocean discharge and implemented beneficial use of biosolids in the 1980's, expanded the wastewater system to full biological treatment in the 1990's, and implemented thermophilic digestion and pasteurization to achieve exceptional quality status for the City's biosolids in the early 2000's. Today, these teams are rebuilding the secondary sewer system and major outfall sewers, enhancing water reuse by microfiltration and reverse osmosis treatment, and retrofitting the City's reclamation plants for nutrient removal. In 2000 and 2004, Bureau projects won the American Academy of Environmental Engineers award for Superior Achievement and Excellence in Environmental Engineering.
