Topic: Ecology/Ecosystem Management/Ecoregions of Texas
Andrew Sipocz is the Region 4 Natural Resource Coordinator, where he develops and implements habitat management and restoration plans for the Texas State Parks in the Houston area. He has been employed by Texas Parks and Wildlife Department since 1990, previously as a habitat assessment biologist, moving to his current position in 2005.
Mr. Sipocz graduated from Purdue University in 1985 with a Bachelors of Forestry degree. He then received a Masters of Science degree in 1993 from Texas A&M University with field research and thesis studying wetland ecology and aquatic insects as food for coastal water birds.
His work with the Texas Parks and Wildlife Department has included assessment of all types of coastal plain and near shore environments in order to provide habitat restoration plans, predicting the impact of proposed development projects, advising scientific study groups, and conducing research on wetland functions.
Andrew Sipocz enjoys woodworking, canoeing, and gardening, and currently lives in Dickinson. He has two children; Isabel, age 8 and Peter, age 3. He also has a dog, Paten, who was named after a marsh grass.

Topic: Weather and Climate of Southeast Texas
Jonathan Brazzell is the service Hydrologist at the Weather Service Forecast Office in Lake Charles, Louisiana. He manages the Hydrology Program within the office, evaluates and implements the latest tools, trains staff on the use of those tools for flood forecasting, and evaluates flood prone areas to determine flooding potential by surveying elevations to buildings and roads.Being at a coastal office, quite a bit of the flooding comes from the Gulf, and Jonathan has been involved in storm surge modeling and efforts to improve those models. He also keeps track of all the geo-spatial information within the Lake Charles office and occasionally works the weather forecast desk.
Mr. Brazzell graduated from the University of Louisiana with a degree in Atmospheric Science. He received the Department of Commerce Silver Medal for performance during the 1997 Red River of the North Flood. He also received the Department of Commerce Bronze Medal for performance during a Tornado Outbreak in 2002 across the southern plains, and the director’s award for service improvement and team work.

Dr. Steven Lewis
Presentation Date: April 14, 2012
Topic: Introduction to Entomology
Dr. Steven Lewis is a biology professor at Lamar University in Beaumont.

He is also a recreational ornithologist and herpetologist.
Dr. Lewis received his PhD in Zoology from Texas A&M University. He also holds a Masters of Biology from Lamar University and a Bachelors of Environmental Science from the Lamar State College of Technology.
