My name is Sabrina. I am a current student in OSCAR program for summer 2018. My work is about investigation and fate of emerging contaminants in Gunston Cove of Potomac river in Alexandria.

We extract micropollutants from water, sediment and fish samples and use liquid chromatography-mass spectrum (LC-MS/MS) method to analyze the extracts. We solid phase extract the micropollutants from water samples and use QuEChERS to extract them from sediments and fish and then run the extracts in the LC-Ms/MS instrument and we analyze the results.

After that, we apply the KABAM model to predict the bioaccumulation of chemicals in organisms’ tissues. More interestingly, the work is collaborative, and this gives me a good opportunity to interact with people with different background and be involved in group work.

This research is the best experience in my academic pathway because I feel that I absorb lot of information related to my field and I am surrounded by a huge, friendly and experienced team working with me in the lab. Moreover, this research involves lot of data analysis and use a lot of literature resources where I learn more about my research and related topics and I develop skills in data analysis and time management. I learn from every single step I process, and I strengthen my experience in the lab work, I interact with people with high experience and I learn to work under pressure of time which I can apply in my daily life as well. I, also, should admit that this research is a guide for me to pursuit my graduate program in the same field of study.
