- Postdoc at LLNL, Physical & Life Sciences Directorate, Livermore, California (Dec. 2015 – present
- My research is advancing our understanding of soil viruses. Current work is applying SIP and NanoSIMS techniques with viromics to characterize soil viruses and virus-host linkages.
- Mentor: Steve Blazewicz
- Graduate Research Assistant, The Ohio State University (OSU), Columbus, Ohio (2015 – Dec. 2018). Previously the University of Arizona.
- Overall project focus is to quantify and predict thawing permafrost response to a changing climate, scaling from genes to ecosystem processes in Abisko, Sweden. My role is to help examine the viral ecology and the viruses’ metabolic potential and quantitatively relate it to biogeochemical fluxes
- Committee: Virginia Rich (adviser), Matthew Sullivan (co-adviser), Kelly Wrighton, and Michael Wilkins
- Graduate Research Assistant, Desert Research Institute (DRI)/University of Nevada, Reno (UNR), Nevada System of Higher Education, Reno, Nevada (2011 – 2013)
- Project focus was to better understand the microbial diversity, biogeochemistry, and specifically the nitrogen cycle physiology of bacteria in brine from Lake Vida, Antarctica. This work :used microbial culture techniques (aerobically and anaerobically) using isolates from this habitat to then study their roles in biogeochemical cycling, with a focus on N2O production. To :do this, I screened cultivars for genes and proteins of interest, quantified their biogeochemistry and used stable isotope techniques to identify isotopomers and isotopologues of N2O to :determine the source (abiotic or biological) and pathways involved in its cycling.

In particular, lectures and activities considered icy satellites, rocky planets in the Solar System, extreme Earth environments, and terrestrial exoplanets.
- I evaluated talks and posters for the biological sciences section of the undergraduate forum March 30, 2016. Prior to this, judges attended a two-hour training session. Applicants were rated on (1) poster presentation (if applicable) :including research content, visual graphics, grammar, and conclusions; (2) oral presentation including appropriate terminology, poise/presentation, knowledge of work, and organization/flow.
- The Ohio State University Viromics training course, Columbus, OH
- The course was held Feb. 8-9 and training included the iVirus pipeline part of the CyVerse infrastructure and MetaVir. With iVirus we learned how to quality check metagenomics sequences, assembly, VirSorter, and mapping the reads to contigs for coverage. MetaVir is a web server designed to annotate viral metagenomic sequences. With these tools, we were able to give our data ecological meaning.

- Sky School is 1-5 day Science programs for Arizona K-12 students at the 25-acre Mt. Lemmon campus. My fellowship was for the 2014-2015 school year. Programs focus on core UA science areas :such as sky island ecology, biology, geology, and astronomy and have been developed in collaboration with local school districts to meet Arizona State and Next Generation Science :Standards. I specifically bridge biology and astronomy and share the field of astrobiology with the students. Fellowship Responsibilities include participating in at least 4-5 Sky School :events in during each semester, in which leading daytime activities and participating in evening activities. Daytime activities are for a group of 5-10 students and include sample :collection, learning projects, and demonstrations. 3+ day trips include a science inquiry project, which is presented before they leave, and an in-depth learning experience on the :graduate fellows field of study.
- Director Dr. Alan Strauss
- March 14-15, 2015 I was a co-exhibitor for the Sky School booth at Science City part of the Tucson Festival of Books. It is the 2nd largest book festival and largest book and science :festival. Our booth had several meteorite samples and thin sections that students could view under the microscopes. We also had some neat giveaways to encourage and promote STEM :education. We also had material on the OSIRIS-Rex mission led by NASA. This huge festival draws a diverse group of people from all over the world. This year we got a special visit from :former Arizona congresswoman Gabrielle Giffords.
- On Feb. 23, 2015 from 7:30-3:30 I was a co-exhibitor for the Sky School both at Sahuarita middle school SciTech festival. There were 480 6th-8th graders that participated and went to each :booth to answer questions in their “passport”. The Shy School booth question was: How can meteorites give us information on the formation of the solar system. Our booth had several :meteorite samples and thin sections that students could view under the microscopes. We also had material on the OSIRIS-Rex mission led by NASA.

- Earth Week & SWESX coordinator, UA, Tucson, Arizona
- School of Earth & Environmental Sciences (SEES) hosted EarthWeek at UA. The SWES department had their own designated day full of oral presentations by undergraduate and graduate students. :In 2014, I was in charge of student recruitment for presentations for the SWES department. I reviewed oral & poster abstracts that were submitted, ordered food, created sessions, reserved :rooms, and judged posters. For 2015 I was chair of the SWES department and a member of the UA SEES EarthWeek. I continued my previous year's duties, along with acting as social chair for :the University; this included planning several trivia nights to encourage city-wide participation in EarthWeek.
- La Cima Middle School Career Shadow Day, Tucson, Arizona

- La Cima coordinator: Vaughn Croft (firstname.lastname@example.org)
- Saturday Science Academy coordinator, University of Arizona
- As the event coordinator I confirmed logistics for the event with Arizona MESA (a university-based outreach program). I planned the activity schedule, recruited activity leaders, :identified keynote speakers, arranged for activity supplies and student prizes, organized volunteers, taught activities to volunteers, ordered snacks for students, provided feedback to :volunteers, and led the event. The goal was to excite ~80 underrepresented middle school students about STEM fields, college, and sponsor future science-related events. In February 2014 :the theme was "Astonishing Astrobiology" and in November 2014, the theme was "A Geological Perspective on Life".
