Research
My research focuses on the epidemiology and economics of Air Filtration Systems for large sow farms. My first project was focused on the risks associated with non-filtered back-drafted air. We were able to demonstrate that this event is an important cause of PRRVS introduction in filtered farms via retrograde air movement. My current project is related to the epidemiology and economics of the production improvements of these farms as a result of the PRRSV free status and in comparison to similar but non-filtered farms.

Research
I am researching anti-thrombotic therapy in dogs with primary immune-mediated hemolytic anemia. Thrombosis, or abnormal clotting, is one of the major causes of morbidity and mortality in dogs affected with this disease, and currently there is little data evaluating different medications to prevent clots from forming. This disease is fairly common and can be very hard to treat. I am conducting a controlled clinical trial evaluating anti-thrombotic therapy in dogs affected with this disease.

Research
Our lab is interested in the gene CD38 and its role in the pathogenesis of asthma. Previous studies from our lab showed that it is playing a role in hyper-responsiveness and inflammation, two of the cardinal features of asthma. Further it was shown that TNF-alpha induced CD38 expression is transcriptionally regulated by transcription factors NFK-B and AP-1 through MAPK pathway. My aims are to determine whether CD38 has a role in remodeling of airways, another feature of asthma and to find out whether CD38 is post-transcriptionally regulated by microRNAs.

Research
My research interests are focused on developing safe and effective therapies to prevent calcium oxalate stone recurrence, evaluating different approaches for gene therapy and the feasibility of these techniques in vitro. Medical therapy to dissolve calcium oxalate uroliths is currently unavailable. There are four major classes of enzymes and related proteins found primarily in plants, fungi and bacteria, able to degrade oxalate. My principal objective is to evaluate enzyme gene expression and activity in a feline kidney cell line, in order to identify potential candidates for future gene therapy applications in dogs and cats.

Research
My research is focused on creating Bayesian epidemiologic models to describe the within-herd transmission of swine Influenza A virus (IAV) with various conditions of the swine production system. The epidemiological model can serve as a tool to bridge unconnected pieces of information obtained from several places in order to provide insights into the underlying process of the IAV transmission. With the goal of developing an effective IAV surveillance scheme, Bayesian epidemiological models are proposed to describe and predict the IVA transmission within the swine herd conditional to piglet production batching, gilt replacement, and vaccination programs. Swine producers and veterinarians can adopt such candidate schemes in designing and implementing production management which mitigate and perhaps eliminate the swine IAV.

Research
Swine Dysentery, caused by Brachyspira hyodysenteriae is a mucohemorragic diarrheal disease of grower-finisher pigs, responsible for significant economic losses globally. In addition, B. pilosicoli causes porcine intestinal spirochetosis, a chronic muco-diarrheal disease, and “B. hampsonii” causes a mucohemorrhagic diarrheal disease which is clinically indistinguishable from Swine Dysentery. Largely disappearing from the U.S. in the late 1980s, the disease has re-emerged across U.S. swine herds during the 2000s. My research involves validation of antimicrobial susceptibility testing techniques, their implementation for studying antimicrobial susceptibility patterns and investigation of potential resistance mechanisms of Brachyspira species. It also involves molecular genotyping, phylogenetic analyses and molecular epidemiological studies to help elucidate the diversity, distribution, dissemination and potential evolutionary patterns of these pathogens. Broadly, I am interested in developing and implementing techniques useful in the diagnosis, prevention, control and treatment of porcine Brachyspira infections.

My research focuses on the prevalence investigation of Staphylococcus aureus including methicillin resistant Staphylococcus aureus (MRSA) in pig and swine veterinarian in U.S to evaluate colonization and infection patterns. We also have determined the predominant S.aureus genetic types using spa typing and MLST methods from isolates to understand the current distribution of this pathogen in pig industry.

My area of research is investigating intra-articular therapies for management of osteoarthritis in the horse, through use of measuring indirect immunologic biomarkers in synovial fluid. Specifically, my current investigation is focused on the intra-articular medication: autologous conditioned serum (more commonly known as 'IRAP').

Awards

Research
A correlation between the gray coat color and melanoma development has long been recognized with up to 80% of gray horses older than 15 years developing melanoma. Both graying and melanoma formation have been linked to a duplication in the Syntaxin 17 (STX17) gene, with the STX17 genotype affecting melanoma grade and severity in the Lipizzaner breed. An ASIP mutation, responsible for the bay/black coat color modifies melanoma risk in gray horses, with increased melanoma severity potentially due to an increase in MC1R pathway signaling. We have identified a population of gray Quarter Horses (QH) that appear to have a decreased melanoma risk. The objective of our study is to determine if the decreased incidence of melanoma in gray QH is related to decreased MC1R signaling resulting from the MC1R chestnut coat color allele. Identification of genetic factors that result in altered melanoma susceptibility will allow for more accurate assessment of prognosis and metastasis risk in horses with dermal melanomas.

My research focus is on the epidemiology of PRRS virus in swine herds with an interest in risk factors of infection including spatial and temporal analysis and mapping. We have worked to develop a database of 10 production companies, of approximately 300 sow herds, representing nearly 1,000,000 sows in 14 states. Using this database, we have designed field trials to understand the effect of PRRS vaccination on the frequency and variety of PRRS viruses detected in air within a region. I have also conducted several trials on the role of oral vitamin D3 supplementation in suckling and post-weaned pigs and the response in performance and immune function.

Research
Osteosarcoma is the most common primary bone malignancy affecting children, adolescents and young adults. Additionally, osteosarcoma is commonly found in canines, with approximately 10,000 new cases each year. The complex biology of osteosarcoma and tumor heterogeneity makes it challenging to identify effective new gene targets and therapeutic agents. We have found that a unifying feature of osteosarcoma is the overexpression of miR-17-92 microRNAs. We have deciphered that deregulation of 14q32miR/cMYC network leads to overexpression of miR-17-92 in osteosarcoma. This deregulation is associated with poorer outcomes in osteosarcoma and is preserved in naturally occurring canine osteosarcoma suggesting a conserved disease mechanism. Upregulation of miR-17-92 miRNAs contributes to osteosarcoma progression by targeting potential tumor suppressor osteosarcoma driver genes such as PTEN. Additionally, our studies show that the prodrug Minnelide inhibits cMYC expression and downregulates miR-17-92 miRNAs. Together, our data suggests that upregulation of miR-17-92 miRNAs contributes to osteosarcoma progression and Minnelide reduces tumor burden in osteosarcoma by inhibiting miR-17-92 expression.

Research
Alteration in gut microbiome has been shown to contribute to bowel dysfunction and gut barrier disruption. We have recently demonstrated that morphine treatment results in significant disruption in gut barrier function leading to increased translocation of gut commensal bacteria. Gut microbiome plays an important role in maintaining gut homeostasis. However, the effect of morphine on gut microbiome has not been investigated. Citrobacter rodentium is a natural mouse pathogen that models intestinal infection by enteropathogenic Escherichia coli (EPEC) and enterohemorrhagic E. coli (EHEC) in humans and causes attaching and effacing (A/E) lesions and colonic hyperplasia. My research focuses on the effects of morphine treatment on host mucosal immunity, gut microbiota, and bacterial virulence in a Citrobacter rodentium-mouse model. My research will expand understanding of effects of morphine on the microbiome-neuroimmune axis, and of its role in the gut homeostasis.
