Dr. Kim A. Anderson

Our research is focused in the field of environmental forensic chemistry which involves the application of chemical concepts to the interpretation, distribution, speciation, and bioavailability of chemicals in the environment (often litigious). We focus on persistent, bioaccumulative, toxic chemicals. We are working at several field sites, mostly throughout the state of Oregon, including the Portland Harbor Superfund Site, and several sites on the Willamette River. We work in several eco-system compartments: dominantly fish, surface waters and sediments. In addition, to classical techniques, we work on development and evaluation of in-situ techniques which mimic organisms, in order to better understand bioavailability. We also look at the effect of episodic events/inputs into an eco-system.


Dr. Siva Kumar Kolluri

Dr. Siva Kolluri obtained Bachelor of Pharmacy with honors from Birla Institute of Technolo­gy and Science, Pilani, India and Master of Technology (Biotechnology) in Bio-chemical engineering from Jadavpur University, Calcutta, India. He worked at the Indian Vaccines Corporation, New Delhi, India and Sanofi Pasteur, Lyon, France for four years. He obtained Ph.D. from Karlsruhe Institute of Technology, Karlsruhe, Germany in the laboratory of Prof. Martin Goettlicher. After postdoctoral training with Prof. Xiao-kun Zhang at Sanford Burnham Prebys Medical Discovery Institute in La Jolla, CA, he joined as faculty at OSU. The major focus of his research is the signaling of ligand activated transcription factors, and the regulation of cell growth and cell death.


Dr. Ivan Titaley

Ivan is a Postdoctoral Scholar working with Dr. Jennifer Field in Dr. Staci Simonich's laboratory. His primary project concerns the method development and analysis of neutral (volatile) per- and polyfluoroalkyl substances (PFAS) in landfill gas using thermal desorption coupled with gas chromotography-mass spectrometry (TD-GC-MS). His other projects included analysis of neutral PFAS in consumer products, and aqueous film forming foam (AFFF), as well as on the applications of computational chemistry or chemometrics in environmental chemistry. Ivan is originally from Indonesia and graduated with a B.A. in Chemistry from Berea College in KY in 2013 and with a Ph.D. in Analytical Chemistry from OSU in 2017. Before coming back to OSU in 2020, Ivan spent two years as a Postdoctoral Researcher at Örebro University in Sweden working on target, suspect screening, and non-targeted analyses of contaminated soils.


Jessica Scotten

I am a Faculty Research Assistant in Dr. Kim Anderson's Laboratory. I work with passive samplers, instrumentation, and manage the SRP Standards Store for the OSU SRP Chemical Mixtures Core. I graduated from OSU with a Bachelor's degree in Microbiology and a minor in Toxicology in 2019. I started working in the department as an undergraduate in 2016 and have been working for Dr. Anderson as a staff member since 2019. Most recently, I have been working with SARL to provide alkyl PAH standards for testing in zebrafish, performing method development in the lab, and helping the department create their first informational booklet. When I'm not working in the fume hood or trekking through muddy sites, I can be found backpacking, biking, and attempting to tire out my border collie.
