Jonathan Clayton, DVM, Ph.D.

The Clayton Lab is studying host-microbiome interactions in humans and nonhuman primates. We are using nonhuman primates as a model for studying the effects of variations in dietary fiber and other dietary compounds, as well as lifestyle factors associated with modernized society, on the microbiome and metabolic health.

Dr. Clayton received his Doctor of Veterinary Medicine (D.V.M.) and his Doctor of Philosophy (Ph.D.) in Comparative and Molecular Biosciences from the University of Minnesota. For his Ph.D. thesis research, he used nonhuman primates as a model system for studying the effects of emigration and lifestyle disruption on the human gut microbiome. During his Ph.D., Dr. Clayton founded the Primate Microbiome Project (PMP) with the intended purpose to develop a systematic map of variation in microbiome structure and function across all primates and to relate this to primate health, evolution, behavior, and conservation.

The Clayton Lab are currently extending our research to explore in detail causal mechanisms for microbiome-modulated metabolic diseases including diabetes and obesity, as well as neurological/behavioral diseases such as stress. We do this using both in vitro and in vivo experiments, including, but not limited to, next-generation sequencing, anaerobic and aerobic culture, germ-free mouse models, and marmoset models.

Kate Cooper, Ph.D.

Dr. Kathryn (Kate) M. Cooper joined the School of Interdisciplinary Informatics at UNO in 2015 and has been a member of the UNO Bioinformatics Research group since September 2005. Her research has focused on application of network science to biomedical data; including network modeling of gene expression data can be functionally interpreted to further understand cellular systems. She has also worked work on developing structural filters in high performance computing environments for analysis of large biological networks; this work explores the relationship between known graph theoretic properties and potential function in protein protein interaction networks as well as correlation networks. She has also collaborated on projects exploring how graphs can be effective tools for modeling systems in broader areas of biomedical and health informatics, such as the spread of infectious disease and the modeling co-occurrence of terms in food products labels. Her current research interests are exploring the impact of diet on the microbiome for prevention of disease using consumer health informatics.

Guoqing Lu, Ph.D.

Dr. Lu’s group is interested in a broad spectrum of bioinformatics problems, ranging from sequence analysis, genome comparisons, to system-level biological interactions. His research spans both theoretical and applied bioinformatics, with a focus on comparative genomics and evolutionary informatics. Dr. Lu’s lab has a number of ongoing research projects, which include the pathogen-host-drug interaction networks at the systems biology level and the invasive species-native community interactions and feedback at the ecosystem level. His lab developed and is currently maintaining several bioinformatics systems, including Phylomarker and FluGenome.

Kiran Bastola, Ph.D.

Dr. Bastola goal as a teacher is to enable students to discover new possibilities and develop skills that open new doors of opportunity. My research is highly interdisciplinary and lies at the intersection between computational and biological sciences with an emphasis on integrating and analyzing large biomedical data sets. I believe, while research provides an opportunity to change the world, teaching and mentoring provide opportunities to make lasting impacts on individuals. Research area of interest include Mitochondrial Biology, Public Health Genomics and Pharmacognosy.

 

 

Martina Clarke, Ph.D.

Dr. Clarke’s research areas include: user-centered design, usability evaluations of health information technology, needs assessment, and clinical workflow analysis. In other words, her research is focused on integrating information technology into healthcare in a way that does not negatively impact clinicians and patients.Her research focuses on reducing documentation burden among care providers, specifically, shared living providers and other direct support professionals.

Paul H. Davis, PhD

Dr. Davis interested in Toxoplasma gondii, which is a zoonotic human parasite with worldwide distribution. Approximately 30% of the U.S. population is chronically infected with T. gondii, frequently acquired from infected cats or ingesting undercooked meats.

In addition to its classical association with fetal malformation and abortion (a leading cause of congenital neuropathy, affecting >1/1000 live births in the US), toxo­plasmosis also afflicts the growing ranks of immunocompromised individuals (cancer and transplant patients, as well victims of HIV). Following infection,bradyzoite cysts invade and permanently reside within tissues, and are completely resistant to chemotherapy. 

Recently, studies suggest that chronic parasite infection affects human behavior; thus the need to more closely examine this parasite stage is increasing. Our research involves studying the formation of this intra-tissue bradyzoite cyst using genomic and genetic approaches, both in vitro and in vivo.   

Moreover, the causative agent of malaria, P. falciparum, shares a close genetic relationship to T. gondii, the latter of which is a frequently used model for malaria research. Due to the ease of growth and genetic manipulation, we utilize T. gondii to investigate several recently tested compounds showing anti-parasitic activity in vitro, in an attempt to develop novel anti-malarial treatments

Jordan Rowley, Ph.D.

Principles of 3D Chromatin Organization
Chromatin is deliberately arranged in the 3D nucleus so that genomic loci can influence each other long-range. The organization of chromatin is altered during development, in response to hormonal signaling, and after heat shock, indicating that the nucleus is a dynamic environment. Abnormal 3D chromatin organization is implicated in diseases such as aberrant limb formation, cancer, and embryonic lethality. My overall goal is to discover mechanisms driving the establishment and dynamics of 3D chromatin organization. Specifically, Dr. Rowley aim to elucidate how looping, insulation, and transvection occur.
