I received my BS in Animal Science and DVM here at University of Minnesota. I had research experience during vet school with various labs on campus focusing on Mycoplasma hyopneumoniae, influenza, and PRRSV. Additionally, I have done numerous field experiments during externships with various swine companies focusing on areas of swine production and health. My goals during my PhD is to better understand swine viruses and focus on virus survivability and inactivation.

My project's goal is to define the genetic basis of equine recurrent exertional rhabdomyolysis (RER), a painful musculoskeletal disorder characterized by rapid necrosis of muscle cells in response to strenuous exercise. RER has been conclusively shown to be a complex genetic disorder with dozens to hundreds of contributing alleles and complex environmental interactions. The first aim of this research is to develop a genetic risk model focusing on alleles of moderate to large effect that can be used to predict individual risk for developing RER and assist in breeding choices. The second aim is to identify underlying pathways and genes containing causative alleles as possible targets for therapeutic intervention.

My thesis is assesses the potential genetic component of Pituitary Pars Intermedia Dysfunction (PPID) in horses. This relatively common disease affects the aged horse population and has many current limitations in proper diagnosis and treatment. The goal of this research would be to identify a way to screen horses for potential PPID development and intervene at an earlier stage with diagnosis and treatment for better disease control.

My research focuses on leveraging emerging genomic and molecular tools to improve detection and characterization of tick-borne pathogens to ultimately help better understand the role ticks play in disease transmission. I have been actively working on developing novel strategies, employing realtime metagenomic and field-deployable biosurveillance approaches, to rapidly detect pathogenic agents from field-collected ticks while simultaneously generating genome-spanning sequence data for strain typing and phylogeny generation. The ultimate goal of these research efforts is to better inform public health surveillance efforts across a variety of vector-pathogen systems, and to develop a rapid and streamlined approach for metagenomic pathogen detection from field-collected samples with applications across a variety of field settings.

Bio
I graduated in May 2023 with my Bachelors of Science in Agricultural Business with a Management minor from the University of Minnesota - Crookston. My research experience includes working for Dr. Adam Mueller and Dr. Nathan Winkelman at Swine Services Unlimited Inc. out of Rice, MN. In this position, I was able to participate in multiple swine research projects at a variety of different levels. I helped with everything from trial administration, day to day observations, and final close outs. I have gotten experience with what it is like to work with different companies and carry out research in the field. This includes documentation, meetings, organization, statistics, and some data analysis to carry out the studies.
My research interest is centered around applied research. There is a uniqueness to each farm and what works for them. Sometimes what the science says works isn’t relevant for the farmer. I want to be able to work with the farmer on making the science relevant to them individually. I have been made aware of the educational gap between scientists and workers with my upbringing. I have found that many times people struggle to bring research findings and communicate them to the general public. I want to be able to bridge that educational gap through my education and research.

Research
My research focuses on developing a genetic predictive assay for autism assistance dogs in collaboration with the Department of Psychiatry and Behavioral Sciences at the University of Minnesota Medical School. The demand for autism assistance dogs is high and the wait to obtain a well-trained autism assistance dog can be 2-3 years or more. The success rate of assistance dogs trained at accredited organizations ranges between 30-50% and the cost of dogs who are released from programs is significant ($30,000+). The goal of this research is to determine specific assistance dog behavioral traits that correlate with positive outcomes for individuals with autism spectrum disorder and develop a prototype multi-marker genetic assay to predict overall success of a potential assistance dog before resources are invested.

I am studying production models and the association with changes in performance parameters (growth rate from birth to wean, survivability from birth to wean, growth rate from weaning to end of nursery phase) as well as differences in disease transmission frequency and microbiome diversity between the two populations. The production models are the conventional model of a litter of pigs being allowed to nurse from the birth sow, with cross fostering as required for litter size equalization compared to a novel model developed which allows pigs from eight to twelve litters to nurse from multiple sows.

Areas of research interest
I am a veterinarian with a background in public health and epidemiology. My ultimate goal is to advance understanding of the ways in which ecosystems, farm environments, and general agricultural management practices influence occurrence of disease in human and animal populations. To that end, my research interests involve the development of laboratory, computational, and statistical methods necessary to characterize potential risks of mobilization of antimicrobial resistance genes between pathogens at the human-animal interface. Currently, my research projects are being conducted in the U.S., Europe, and Africa.

Areas on research interest
I am interested in antimicrobial resistance genes from animal productions especially poultry production. My research focuses on determining an association between antimicrobial resistance patterns and antimicrobial usage within poultry farms in California to develop appropriate antimicrobial stewardship guidelines and best management practices.

Research
My research is the development of novel surveillance methods to enhance our understanding of epidemiology of swine infectious diseases, especially porcine reproductive and respiratory syndrome virus (PRRSV) and swine influenza virus (IAV-S), and advance the regional control of these diseases.

Area of research interest
My research is focused on characterizing circular RNAs in the field of veterinary medicine, looking into their potential as a future diagnostic and therapeutic tool for companion animals – on one hand utilizing them as biomarkers for canine malignancies and, on the other hand, experimentally navigating their immunogenic properties as immune boosters towards plausible vaccine adjuvants and immunotherapy- an area that to this date remains completely unexplored.
