Rolf Halden, Ph.D., P.E., is Director of the Center for Environmental Security at the Biodesign Institute, Professor in the School of Sustainable Engineering and the Built Environment at Arizona State University and Senior Sustainability Scientist at the Global Institute of Sustainability. His research labs are housed in the Center for Environmental Biotechnology at the ASU's Biodesign Institute. Rolf received a Master's in Biology (Diploma, 1992) from the Technical University of Braunschweig, Germany, and a Master's (1994) and Ph.D. (1997) in Civil Engineering from the University of Minnesota. Prior to joining academia, Rolf was project engineer at the Lawrence Livermore National Laboratory, where he directed the construction and operation of physical and biological groundwater treatment systems. He has served on the Maryland State Water Quality Advisory Committee, the Food and Drug Administration's Nonprescription Drugs Advisory Committee, and a National Research Council committee of the National Academies.

Dr. Halden's research explores the connection between anthropogenic activities, environmental quality and human health. His research relies heavily on the use of mass spectrometric tools (e.g., LC-MS/MS, MALDI-TOF) for applications in environmental proteomics, bioremediation and public health engineering. Ongoing projects focus on:

 

Research Faculty

Dr. Benny Pycke
Research Faculty
Email: bpycke@asu.edu

Benny investigates the fate of bioactive organic chemicals and nanoparticles from personal care products in the natural- and built environment. He researches their effects on human health and microbial communities, and he develops remediation technologies to remove these recalcitrant chemicals from our waste streams. His research relies on both analytical instruments (e.g., LC/MS and LC/MS/MS) and molecular microbiology tools (e.g., T-RFLP, DGGE, qPCR, FISH, and flow cytometry).

Dr. Bhagyashree Manivannan
Postdoctoral Associate
Email: Bhagyashree.Manivannan@asu.edu

I am exploring the world of peptides and proteins using MALDI-TOF, liquid chromatography and tandem mass spectrometry at the Biodesign Institute, Arizona State University. At our, Centre for Environmental Security Mass Spectrometry Facility, we intend to analyze environmental and biological samples for candidate biomarkers to address the global human and environmental health issues.

Yegamabram

Dr. Manivannan Yegambaram
Postdoctoral Associate
Email: Manivannan@asu.edu

I am involved in quantitative and qualitative analysis of proteins, peptides and small molecules at the Mass Spectrometry Facility, Center for Environmental Security, (Biodesign Institute at the Arizona State University). In our laboratory, the experimental approaches for protein mass spectrometry include sample preparation, gel and off-gel electrophoresis and analysis of proteins/peptides associated with human and environmental biosecurity using MALDI-TOF MS and LC-MS.

Arjun Venkatesan
Doctoral Research Associate
Email: avenka21@asu.edu

Arjun's research involves identification of emerging contaminants and the role of human society and the built environment in the redistribution of these potentially harmful substances in the environment and in biota. His research seeks to evaluate risks posed by anthropogenic chemicals and improve communication with the public to arrive at a more transparent and responsible management of chemicals in the U.S., thereby addressing ecological, human health, and societal issues.

Graduate Researchers

Hansa Done
Doctoral Research Associate
Email: hansa.done@asu.edu

A student of the Biological Design PhD program, Hansa is concerned with protecting the efficacy of antibiotics for use in human health. The focus of her research is the unnecessary usage of antibiotics in aquaculture and the associated microbial resistances that may develop due to continued exposure to sub-lethal antibiotic concentrations. Her work utilizes mass spectrometry (LC-MS/MS) as well as molecular tools to understand the true consequences of antibiotics in the natural environment.
