Dr. Blake Wiedenheft

I like viruses. My career has been dedicated to understanding the mechanisms that viruses use to manipulate their hosts and the counter defense systems that microbes employ to defend themselves from infection. As a pre-doctoral fellow, my dissertation focused on the unusual viruses that infect thermoacidophilic archaea. In what was maybe the best Ph.D. project ever, I traveled around the globe collecting samples and isolate viruses from geothermal features located in some of the world's wildest places (e.g., Yellowstone National Park, Kamchatka Russia, etc.). The resilience of life in these seemingly inhospitable environments (i.e., +80C and ~pH3) fueled my curiosity to understand the genetic, biochemical, and structural basis for life at high temperatures.

Today I continue to be intrigued by the mechanisms of resistance but instead of high temperate my lab aims to understand how bacteria contend with pervasive viral predators. Our work focuses primarily on understanding the structural and functional basis of adaptive immunity in bacteria.

"My favorite question is “Why?”. I want to know not only how life works, but why it works the way it does. This question has been driving my scientific career through very diverse fields. I started my scientific path in Siberia, studying tick-borne pathogens. After completing my masters, I then earned a PhD in Molecular Biology developing anti-cancer drugs. It was a lot of animal work. No brag, just fact: now I can inject mice in the tail vein with my eyes closed. In 2018, I made an exciting switch to gene editing and became a part of Wiedenheft lab."


Andrew Santiago-Frangos

As a Ph.D. student, I studied the bacterial RNA chaperone Hfq, which facilitates the annealing of regulatory small RNAs (sRNAs), to mRNAs encoding stress response genes and virulence factors. My work showed that the unstructured, acidic C-terminus of Hfq mimics nucleic acids to regulate the binding, competition, and release of RNAs from Hfq’s structured N-terminus.

Phages have nefariously co-opted Hfq (Host Factor for phage Q-beta replication). I’ve been drawn to bacterial defense against phages, in the form of another RNA-guided genetic regulation pathway, the CRISPR systems. CRISPR is an adaptive immune system, that creates long-lasting, specific protection against previously encountered phages. I am fascinated by how CRISPR distinguishes self from non-self, as well as the creation of immunological memory when a bacterium initially encounters a given phage.


Artem Nemudryi

My passion is gene editing. I feel extremely lucky to work in science today, when we have power to alter DNA of all living organisms, including our own species. My scientific journey started with induced pluripotent stem cells and eventually led me to CRISPR/Cas9. I want to improve this technique and contribute to its advance to clinical applications. My dream is to see the world, where genetic diseases could be cured as easy as a runny nose.

I am an undergraduate student studying Biochemistry and Cell Biology/Neuroscience. I spend my time in the lab exploring Type III CRISPR systems through cloning, expression, and recombinant protein purification techniques. When I'm not doing research, I enjoy playing the piano and violin, hiking, skiing, and reading. 


Calvin Cicha

I am interested in improving algae bioproduct production through genetic modification, and better understanding the consequences of algae-virus interactions. Algae show great potential as a sustainable source of fuel and other useful bioproducts. I want to elucidate how algae metabolic systems process nutrients and how to manipulate these systems to produce desired products. Further, I am intrigued by how algae have evolved to survive in competition with lytic algae viruses.

I am passionate about the science and engineering behind water. For my undergraduate degree I studied various water bodies and did my senior research project testing for Volatile Organic Compounds in US Water Bodies. I then went on to work for a water company in their laboratory, working on sampling, testing and compliance.  While working I obtained a graduate degree in Environmental Science, with an emphasis in Civil Engineering. I continued to work in environmental compliance for the next several years and then took a break to be home with my kids. My family and I moved to Bozeman in the Summer of 2018. We have two young boys, ages 8 and 5, and a grandpa. For the last couple of years, I have been wanting to get back into the water industry, so when I saw that the Wiedenheft lab is researching SARS-CoV-2 in wastewater, I wanted to help and be a part of an amazing team.

During my Masters work here at MSU, I developed skills in Transmission Electron Microscopy (TEM) and the Cryo-EM workflow for both Single Particle & Tomography experiments. I have a great appreciation for the physics that govern the TEM and love solving the unique problems associated with optimizing new protocols, be it sample preparation or data collection. We are in an exciting time for the field of Cryo-EM as the associated technology is progressing rapidly, bringing more and more answers to complex biological questions within our grasp as scientists.

In the Wiedenheft lab, I research prokaryotic immune response, hoping to use Cryo-EM to examine this process in situ at high resolution with visual proteomics experiments.

Trevor Zahl

I am fascinated by interactions between parasitic genetic elements and their hosts. Specifically, I am interested in how we can steal the machinery that mediates these interactions and apply it to improve today's human experience. Currently, I am focused on interrogating the function of a wildly diverse group of prokaryotic argonautes (pAgos). I hope we can harness the various biological roles of pAgos to usher in the next generation of genome editing and molecular diagnostic technologies.

Andrew Scherffius

I am originally from Bozeman, but in the fall of 2021, I returned to Montana after ten years living in Colorado and abroad, to work as a laboratory technician in the Wiedenheft Lab. My background is in the humanities, including in the history of medicine. During graduate work at McGill University, I became interested in the practice of medicine, at which point I pivoted and started studying the sciences. As I have plotted my path to medicine, I have become increasingly interested in basic research and how curiosity in the lab transforms into broader, sometimes clinical progress. In the Wiedenheft Lab, I get to learn not only about viral diagnostics and therapeutics, but also how scientists approach never-before-considered problems. In the process, I am incredibly grateful to be a part of an incredibly generous and brilliant team.

Dr. Royce Wilkinson

I enjoy the interface between chemistry and biology. I've worked in labs doing organic synthesis to natural product isolation to protein biochemistry. One of the basic outcomes of scientific research is the identification and characterization of biological entities (natural products, proteins/enzymes, etc.) and adapting them as tools for use in the lab or to bring a benefit to society. CRISPR-based genome editing is one of the latest 'headline producing' examples of the ways that basic scientific research can lead to paradigm shifts in the way we do science or live our lives.

 Will Henriques


I am interested in the interplay between genomes and their environment. I was carried into the Wiedenheft lab by a desire to understand the architecture of the transcriptional programs executed by genomes in response to salient stimuli – threat, feast, famine, etc - and how those programs are updated, hijacked, and hacked.


Lab Alum

MaryClare (MC) Rollins


I am fascinated by the biology and ecology of bacteria and their viruses. I want to understand how complex interactions between bacteria and phage have been shaped by billions of years of co-evolution, and how these interactions affect larger ecosystems. I'm currently working on structure/function studies of bacterial adaptive defense systems.

Reece Erickson

I’m interested in the evolutionary battle that’s occurring between bacteria and their viruses.  I’m especially fascinated in the interactions between bacteria and bacteriophage in structured communities such as biofilms. The bacterial defense mechanisms, like CRISPR, that our lab specializes in are very important for bacterial resistance to viral infection, and I’m extremely excited to have the opportunity to merge bacteriophage, CRISPR, and biofilm research into a single project.

Gabby is a Cell Biology & Neuroscience undergraduate at MSU. She has a strong passion in using CRISPR/Cas9 methodology to treat neurodegenerative illnesses & yield environmentally-efficient biofuel. When not in the lab you can find her backcountry snowboarding, mountain biking, doing mountain landscape photography, & playing guitar in the local band ‘Pacific People’. 

Ian Novak

I am an undergraduate studying Biochemistry and Biological Engineering and I was drawn to the Wiedenheft Lab because of the obvious passion the lab demonstrates for microbiological research and CRISPR systems.  Recently, I've been learning about some very neat science having to do with phage isolation and annotation and I'm more than excited to continue down this path of investigation.  When not busy with school work, you might find me training with the Bridger Biathlon Club, practicing my violin or relaxing in a park slacklining and reading Tolkien.  

Dominick Faith

My name is Dominick Faith, I grew up about five hours north of Bozeman in Kalispell Montana. I will be going into the junior year of my undergraduate studies here at MSU, and I am majoring in Cell Biology and Neuroscience. I first heard about CRISPR during a presentation my classmates were doing in a biology class I took last year. Upon doing further research on the subject I became truly fascinated with the CRISPR technology and needed to know more about it, that's where the Wiedenheft lab came in. I am currently in the sponge stage of the lab where I do my best to absorb any information that comes my way from everyone in the lab. And I'm loving every minute of it.

Paul Van Erp

I'm interested in molecular machines aka proteins. Nature has optimized these tiny Nano-machines during the eons of evolution. By understanding how these machines work in exhaustive detail we will be able to design our own in the future. (This technology can then be used to create bonsai-animals, because who doesn't want a tiny sperm whale for your aquarium, or dog-sized mammoth running around the Living room)
