About me & research interests
I am a proud father and husband. I have always had a love for the environment and have been interested in how science and policy can shape our future. I love teaching and outreach, and believe it is our duty as scientists to shape the next generation. I use meta-omic approaches combined with other tools, such as stable isotope probing, to detect and characterize viruses and virus-microbe interactions in soil ecosystems. My passion is understanding the mechanisms viruses use to control microbial physiology and the ecosystem-level impact.
My research interests are:
Microbial Ecology, Virology, Environmental Science, Biogeochemistry, Astrobiology, Geobiology, Environmental Microbiology, Meta-omics, Climate Change, and Biotechnology
Major research themes include:
- How do microbial community structure and viruses affect biogeochemical processes and the functioning of soil ecosystems?
- How do climate change and other anthropogenic disturbances impact the structure and function of soil microbial communities, and how do these microbial responses feed back to ecosystem and global processes?
- How do viruses, microbes, and their interactions change among soil environments and in response to environmental change (e.g., permafrost thaw and drought)
- Can we predict microbial functions and virus-microbe interactions under certain soil environmental conditions?
- How can we use microbes and viruses for biotechnology to mitigate climate change and improve healthcare.

Current projects
I am working on two main projects with a diverse team from many Universities and National Labs.
1. Quantitative Viral Assessments for Improved Biomonitoring
LLNL LW-LDRD awarded to Gary Trubl
The goals of the LDRD are to (1) create a quantitative SIP-meta-omics pipeline to characterize single-stranded and double-stranded DNA and RNA viruses from a single soil sample and (2) use radioactive phosphate to quantitate and track virions persistence in soil.
2. Microbes persist: systems biology of the soil microbiome
DOE SFA; project lead Jennifer Pett-Ridge. Collaborators from Lawrence Berkeley National Lab, University of California Berkeley, Northern Arizona University, The Ohio State University, and Environmental and Molecular Sciences Laboratory/Pacific Northwest National Lab
The ultimate goal is to determine how microbial soil ecophysiology, population dynamics,
and microbe-mineral-organic matter interactions regulate the persistence
of microbial residues under changing moisture regimes
Objectives include:
- Apply SIP-metagenomics to delineate how changing water regimes shape activity of individual microbial populations and expression of ecophysiological traits that affect the fate of microbial and plant C
- Identify and quantify mechanisms of mortality in the soil microbiome (focusing on phage lysis and water stress) and their contribution to C turnover and the biochemistry of microbial residues
- Measure how the soil microbiome and its products (cell envelope, extracellular polymeric substances, exo-enzymes) interact with contrasting mineral assemblages to control both short- and long-term soil C persistence
- Synthesize genome-scale ecophysiological trait data, population-specific growth and mortality, and SOM chemistry to build models of microbial functional guilds and SOM turnover, to predict the long-aspired connection between soil microbiomes and fate of soil C
My role is to characterize soil viruses and virus-host linkages from SIP-metagenomics and track the phage impact from wet-up.

- 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.

Teaching, outreach, & other experiences
I have had to overcome many obstacles to get to where I am now and these obstacles have shaped my teaching philosophy and my ability to empathize with students who confront challenges during their academic careers. My goal as a mentor is to foster curiosity and academic growth while encouraging inclusiveness, unity and camaraderie. To promote diversity, equity, and adopt an inclusion mindset I have engaged in many mentoring and outreach activities as well as sought professional development courses. My plan is to continue with my education to recognize and mitigate all possible unconscious biases that I may have.
My two main mentor philosophies
- 1. Criticism and praise can only be constructive if they are detailed
- 2. Every task we ask students to complete is essentially a different task for different individuals

- 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.

- La Cima coordinator: Vaughn Croft (vaughn.croft@schools.pima.gov)
- 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".
- DRI representative, Marsfest 2013 in Death Valley National Park
- March 1–3, 2013 a festival celebrating extreme environments was held at Death Valley National Park to get the public involved in STEM activities. The agenda included presentations, booth expositions, and field trips (Badwater basin and other park sites). I presented posters to the public, showcased DRI, and collected samples on field trips with youth for viewing under a microscope. Attendees also camped at the park overnight and participated in astrological activities.
- Graduate outreach aid, University of Nevada, Reno for George L. Dilworth Middle School
- We visited weekly through the fall and episodically through the spring. Topics and activities included microbiology mysteries (e.g., 1854 cholera outbreak, 1993 Milwaukee Cryptosporidium outbreak), chemistry demonstrations (e.g., vinegar and baking soda, Coke and Mentos), and math lessons (e.g., calculating how much water we use in a year). Primary activities included interacting with students to solve science problems, working with students to develop STEM research projects, and participating in career day.
- International Stable Isotope Biogeochemistry summer course at Michigan State University (Summer 2012)An intensive one week course. Mornings were filled with lectures on the different types of Mass spectroscopy, carbon, nitrogen, and sulfur cycling, and the stable isotopes of C, H, O, S, and N. Afternoon and evenings consisted of lab rotations analyzing and interpreting samples.
