  • What We Do

    Here are a few of our current projects....

    Antibiotic Resistance, Pathogenicity and Survival

    A walk on the wild side

    Severe climate events, such as the recent massive floods associated with hurricanes and unprecedented snow packs, create environments that bring together bacteria that normally do not interact with each other. Since bacteria can and do readily exchange genetic material even across species, these events have the potential to create novel genetic combinations with increased human disease potential.

    Phage Therapy

    What doesn't kill you makes you stronger

    We recently became part of a larger project with Sandia National Lab, looking at ways to use phage to specifically target certain human pathogenic bacteria. Photo of phages infecting Pseudomonas aeruginosa courtesy of Kasandra Velarde.

    Radiation Survival Mechanisms

    Some like it hot

    Mechanisms of extreme radiation resistance remain elusive. We have created some of the most radiation resistant organisms known, and are investigating their unique characteristics. Photo of Halobacterium salinarum colony courtesy of Matt Ford (used with permission).

    Fingerprint Imaging

    What's a shedder?

    The goal of this project is to develop a safe, cost-effective portable field system for sensitive, interference-free latent fingerprint identification and DNA extraction. The system will be based on near infrared (NIR)-to-NIR upconversion luminescence from optimized nanoparticles (UCNPs) and be capable of capturing highly resolved fingerprint images under full ambient lighting, even on highly fluorescent surfaces. This is an interdisciplinary project, headed by researchers from South Dakota School of Mines and Technology and the University of South Dakota.

    M.S. student

    M.S. student

    Ashley was born and raised in New Mexico. She has been a microbiologist and virologist since she was 16, starting off collecting phages from the Rio Grande and culturing bacteria from plants. She received her BS in Biology from NMT and is currently an MS graduate student at NMT. Her project is in collaboration with Sandia National Labs, focusing of phage therapy, developing a phage cocktail that works against antibiotic resistant strains of Pseudomonas aeruginosa. She also has experience with soil, cannabis, and algal microbiology and phage work. She plans on working in government or industry after graduation. Outside of lab she has two dogs, plays guitar, and collects plants. You know when Ashley is working because heavy metal is blasting. Fun fact: Ashley broke her arm in a mosh pit last summer.

    M.S. student

    Kimberly is a dually-enrolled BS/MS student from Colorado Springs. When she began working towards her degree, she was uncertain of which specific field of biology she wanted focus on. However, after having the opportunity to participate in drug discovery research, she found her passion in microbiology and pathology. She has since transitioned from testing the effects of novel compounds on bacteria and fungi to examining how the environment influences the spread of antibiotic resistant microbes. Kimberly will be completing her BS in May of 2019 and continuing to work on her MS the following semester, hoping to graduate in 2020.

    Undergraduate student

    Heather is the youngest child of a military family. She grew up all over Germany and spent school vacations exploring Europe. She hopes her future career will allow her the opportunity to go back. In May of 2020, Heather will earn her B.S. in Biology at New Mexico Tech, and plans to continue her education by attending graduate school. Her primary interests include: soil microbes, genetics, and forensic science. She started research her sophomore year with Dr. Benjamin Duval on a project which examines the relationship between the soil microbial communities of invasive and native NM shrubs, with a paper soon to be published! Her project with Dr. DeVeaux has applications in the field of forensics. Heather is testing whether or not specially-engineered nanoparticles for fingerprint analysis affect the ability to extract viable DNA from those fingerprints. Heather loves sharks and if she can she'd love to be involved in shark conservation later in life.

    Undergraduate student

    Kasandra Velarde started research in the department in Spring of 2019. She has worked on various organisms, including Chlamydomonas reinhardtii and Pseudomonas syringae. She recently interned at the University of Georgia in the Plant Pathology Department working in plant immunology, summer of 2018. Currently she is working in conjunction with Ms. Chavez on phage therapy. She is pursuing a Bachelor’s degree in Biology and intends to pursue a Master’s in Microbiology. Outside of work she stays active in clubs and sports.

    BUT REMINDER: It’s time to B. cereus about getting this degree!

     
     
     
     

    Undergraduate student

    Raymond began working in the lab his freshman year in the fall of 2018, gaining experience and learning new things from his fellow peers. He is currently working on his Bachelor's degree in Biomedical Sciences and plans to graduate (he hopes) in 2022. When he’s not in the lab or working on papers for his classes, Raymond enjoys playing piano and guitar as well as participating in the Council for Climate Change Club and Techie Stand Up here at New Mexico Tech. Additionally, Raymond probably owns too many Metallica shirts for his own good.

    Undergraduate student

    In order to achieve his goals, Zumruck is currently pursuing a B.S. in Biology with the hopes that he can become a graduate student and study either microbiology or the medical sciences. By being part of this team he hopes to experience different fields and gain a better understanding of the dynamics that surround contributing to both research and a lab. His free time is spent engaged in club activities such as with the Engineers Without Borders club and their Guatemala Project as well as learning new recipes to cook. Though sadly he still has much to learn as evident by the burnt French toast he made the other day.

    Incoming Ph.D. student

    Completing her baccalaureate in computer engineering in 1986, Faye Schilkey's career spanned programming assembly line controllers for the automotive industry to real-time autopilot and guidance missile systems to IT, databases and bioinformatics software. For approximately the last 12 years Ms. Schilkey has specialized in next generation sequencing and bioinformatics technologies and leads multidisciplinary teams in productive research collaborations. She has worked at the National Center for Genome Resources since 1996 and has been the Director of the New Mexico IDeA Network for Biomedical Research Excellence (NIH NIGMS 2P20GM103451) Sequencing and Bioinformatics Core since 2007.
