My broad research interest is in biomarkers of environmental exposure. We have very little understanding today of what exposures lead to chronic illnesses such as cancer, diabetes, and Alzheimer’s. I focus on how we can use molecular indicators in human blood to show how certain human exposures can lead to differences in risk of chronic illnesses within a population. Specifically, I am looking at the relationship between small RNA transcripts, called microRNA, found in blood and onset of diabetes. In the era of “big data” analysis, I have found that it is also important to work on method development a priori for sensitive and reliable detection of these blood biomarkers.

Why I chose the Berkeley EHS program

I chose Cal EHS because of the fantastic opportunity to work on cutting-edge research with distinguished professors and mentors in a department that emphasizes the applied biological sciences. Here I am able to explore a variety of multi-disciplinary aspects of environmental health as well, and engage with students in related fields including engineering, green chemistry and molecular biology. There are also a myriad of resources at our fingertips on this campus, from use of state-of-the-art instrumentation to excellent courses on data analysis and interpretation. I knew that an education in EHS would help me expand my skillset as a scientist while allowing me to work with the intention of creating a positive impact in the scope of public health.
