Sara Anderson

I am an undergraduate pursuing a degree in Forensic Science at Arizona State University. Additionally, I am a student of Barrett, the Honors College, and I am currently working on an undergraduate thesis under the guidance of Dr. Gwyneth Gordon. We had the privilege of acquiring soil samples from the University of Tennessee Anthropological Research Facility in Knoxville. We are examining the elemental and isotope concentrations in the samples, especially those of carbon (C) and nitrogen (N). With this research we hope to shed some light on the kinds of chemical processes that occur in soil as a body decomposes on top of it.

In addition to the research I do in the Anbar Lab, I am on a research team as a part of a program called the New College Undergraduate Inquiry and Research Experiences. On this team, I work with Dr. Josep De Alcaraz Fossoul on a project that seeks to answer questions regarding fingerprint degradation over time and fingerprint age determination. I and another undergraduate on our team will be presenting our findings at the American Academy of Forensic Science in February 2018.

After I graduate, I hope to acquire a position in a crime lab and eventually work my way up to pursuing a career with the Federal Bureau of Investigation.

I am currently a senior majoring in Chemistry and minoring in English Literature at Arizona State University. Since Fall 2015, I have worked as an undergraduate researcher in the Anbarlab. During my sophomore year, I researched the iron (Fe) isotopic composition in pine trees and possible relationship to biomass burnings with Alyssa Sherry.

I presented the results of my summer research, “Forest Fires as a Possible Source of Isotopically Light Marine Fe Aerosols” at the American Geophysical Union (AGU) conference December 2016.

During the 2016/2017 academic year, I was awarded a NASA Space Grant fellowship. With the aid of this fellowship, I attempted to separate neutral calcium isotope species by liquid-liquid extraction.Recently, I attended a summer fellowship at Woods Hole Oceanographic Institution (WHOI). At WHOI, I had the opportunity to use an osmium- dating method to establish robust chronologies of three sediment cores in the South Pacific Gyre. I will continue studying Fe- isotopes in these clays in an attempt to reconstruct Fe sources to the South Pacific over the Cenozoic as my senior thesis. I will present the results of this research at the Ocean Sciences Meeting in February 2018.

Upon completion of my undergraduate degree, I plan to pursue a Ph.D. in chemical oceanography at a major university. After receiving her Ph.D., and completing my postdoctoral studies, I hope to have a career in academia where I can both teach aspiring young chemists and conduct novel research.


Lily Wayne

I graduated from Hamilton High School in Chandler, Arizona in 2016, and I am currently a sophomore at Arizona State University majoring in biochemistry. In the fall of 2016, I joined Dr. Anbar’s lab and worked with Wang Zheng on a project that studies how mercury cycles through the environment by measuring its isotope concentrations in various samples. Under the mentorship of Steve Romaniello, I also participated in a project that studies the progress of bone loss in patients by measuring changes in calcium isotope ratios in biological samples from astronauts. In 2017, I became a NASA Space Grant Scholar, and with this grant, I plan on exploring ways to measure bone density and the risk of developing bone diseases by using samples from past patients who have undergone hip surgery to study the relationship between calcium isotopes in the bone and blood.
