Dr. Brooke Mayer is currently an Assistant Professor in the Department of Civil, Construction and Environmental Engineering at Marquette University.  She graduated from the Environmental Engineering program at Arizona State University (B.S. – 2004, M.S. – 2006, Ph.D. – 2008), where she taught from 2008 – 2012.  Her research and teaching interests primarily relate to sustainable drinking water treatment and environmental microbiology.  Recent research projects have included:

  • Assessment of the removal and inactivation of emerging viruses using enhanced coagulation and ultraviolet disinfection
  • Development and validation of new techniques for detecting and quantifying infectious waterborne viruses
  • Use of titanium dioxide photocatalysis for the reduction of disinfection byproduct formation
  • Identification and evaluation of novel techniques for the removal and recovery of phosphorus from water and wastewater

Dr. Mayer has also taught a variety of engineering courses, including: Technology, Society, and Sustainability; Global Engineering; Statics; Engineering Business Practices; Numerical Methods; Unit Operations; and Environmental Microbiology.

E-mail: michael.dollhopf@marquette.edu

Mike Dollhopf is the Laboratory Manager for the Water Quality. He received a Master's degree from the University of Wisconsin – Milwaukee in the field of microbiology, with emphasis on environmental and molecular microbiology, biogeochemistry, and environmental studies. For his degree, he isolated and studied new species of metal respiring bacteria using electrochemical techniques. Mike is presently the Manager of the Hydraulics Laboratory, College of Engineering Lab Safety Officer, and Chemical Hygiene Manager for the College of Engineering. Besides work at UW-Milwaukee, he has worked at the Jet Propulsion Lab in Pasadena, CA developing sensors to detect signatures of life for placement on remote landers. Mike also worked at Michigan State University using bioaugmentation techniques for remediating field sites contaminated with chloroethene compounds using microbial consortia enriched in lab and then injected into the contaminated sites and monitored in situ using molecular techniques. Mike more recently worked at Florida State University, investigating metal reducing and other physiologically important microbes in salt marshes and coastal wetlands, and also was involved as chemical analyst for a water quality assessment of the Apalachicola Bay National Estuary Research Reserve. In the Marquette Water Quality Center, Mike is responsible for lab safety, upkeep, and instruction on proper use of lab equipment (ICP-MS, GCs, TOC analyzer, Kjeldahl apparatus, PCR cyclers, temperature-controled room, incubators, freezers), and graduate and undergraduate student supervision. Mike also enjoys working on the many projects proposed by undergraduate groups involved with testing contaminated water purification processes for use in underdeveloped countries. Mike is a Milwaukee native, and is enjoying life back in his hometown area with two young boys who he is proud to say are becoming rabid Packer fans.

Graduate Students

Allen Williams

Allen Williams
MS student
E-mail: allen.williams@marquette.edu

Allen is an MS student at Marquette University in the Department of Civil, Construction and Environmental Engineering. He is working with Dr. Mayer and Dr. Zitomer on nutrient removal/recovery from municipal wastewater treated using anaerobic bioreactors. Allen is reviewing current methods for ammonia and phosphorus removal and will be proposing pilot treatment studies for future research. Recovery of the nutrients and low energy usage are the main goals. Allen obtained his Bachelor of Science in Biological Engineering from the University of Missouri- Columbia (Mizzou) where he studied environmental engineering and water resources from 2008 to 2012. While at Mizzou, Allen performed research on soil/water conservation and rainfall. He also worked on phosphorus removal pilot study at a dairy processing plant for The Probst Group in 2012.

Current Project Title: Ammonia and Phosphorus Beneficial Use Processes and Technologies Evaluations

BSE student
E-mail: patrick.mullen@marquette.edu

Patrick has been an environmental engineering undergraduate student at Marquette since 2009, and plans to graduate in December 2013. He is currently working on a research project to improve the removal and recovery of phosphorus from natural water and wastewater using titanium dioxide photocatalysis. He has also constructed a bench-scale UV light reactor for the project and has begun testing samples to determine the extent of conversion of organic phosphorus to inorganic phosphorus. While at Marquette, Patrick has been a member of the Annex Bowling League and Club Ultimate Frisbee Team.
