Specialty/Research Focus:
Autoimmunity; Immunology; Neurobiology

Research Summary:
My research is aimed at understanding the roles of the innate and adaptive immune systems in health and disease. The organs of my interest are the two specialized filtration units, glomeruli and blood-brain barrier, of the kidney and brain respectively. Recently, our understanding of the immune system has undergone a substantial paradigm shift: researchers now recognize that the innate immune system, the body’s first line of defense, assesses the level of danger of a particular event and initiates an adaptive immune response that subsequently confers protection. My studies focus on the role of an important arm of the innate immune system, the complement cascade in inflammatory conditions such as glomerulonephritis and lupus. For both disease conditions, the perfect therapy remains an enigma. Using a gamut of techniques, we are attempting to define the molecular mechanisms involved and the resulting behavioral aberrations. Once molecular targets are identified, therapeutic strategies will be defined. I teach in UB’s Discovery Seminar Program, which is geared for first- and second-year undergraduates. The seminars are taught in a small-class environment to students who share common goals and similar interests, in ways that enhance their academic, civic and personal growth. I teach “The Yin-Yang of Biology” and “Brain: Day and Night,” and I teach as well in UB’s Honors College. I also mentor students through the CLIMB-PRO program. One of my recent students conducted research that resulted in a publication in the journal Kidney International.

Specialty/Research Focus:
Allergy and Immunology; Rheumatology; Immunology; Autoimmunity

Research Summary:
My research revolves around IL-14 and its role in immunological memory. Studies delve into 3 areas - vaccination, autoimmunity and lymphoid malignancies. The majority of my current work involves studies examining early events in Sjogren‘s syndrome. We have identified new autoantibodies that occur early in the course of the disease. We are examining mediators involved in the early injury to the salivary and lacrimal glands. We are studying events that result in the transition from the autoimmune disease to lymphoma.

Research Summary:
My primary research is in the field of biomedical ontology development. An ontology is a controlled, structured vocabulary intended to represent knowledge within a particular domain. Terms in an ontology have logical relationships to each other and to terms in other ontologies, to allow for reasoning and inference across the ontology. Biomedical ontologies allow annotation and integration of scientific data within particular fields of science and medicine, and their careful curation and logical structure facilitate data analysis. My work in biomedical ontology is strongly informed by my earlier experience in laboratory research in immunology, genetics, molecular biology and virology. My research group works on ontologies for both basic and clinical applications, in collaboration with researchers both at UB and other institutions. I led efforts to revise and extend the Cell Ontology, which is intended to represent in vivo cell types from across biology. We worked extensively to bring it up to community-accepted standards in ontology development, placing particular emphasis on improving the representation of hematopoietic cells and neurons. We are developing the Cell Ontology as a metadata standard for annotation and analysis of experimental data in immunology in support of the National Institute of Allergy and Infectious Diseases (NIAID) ImmPort Immunology Database and Analysis Portal and Human Immunology Project Consortium. We have also developed ways to use the Cell Ontology in support of the analysis of gene expression data linked to cell types and have contributed to the Functional Annotation of the Mammalian Genome (FANTOM) 5 Consortium‘s work on identifying gene transcription start sites across multiple cell types and tissues. My research team is also developing the Neurological Disease Ontology to represent clinical and basic aspects of neurological diseases in order to support translational research in this area. In collaboration with clinical colleagues at UB, we are initially focusing on Alzheimer’s disease and dementia, multiple sclerosis and stroke. We have as well developed a companion ontology, the Neuropsychological Testing Ontology, to aid in the annotation and analysis of neuropsychological testing results used as part of the diagnosis of Alzheimer‘s disease and other neurological diseases. I am a long-term member of the Gene Ontology (GO) Consortium and have a particular interest in the representation of immunology and neuroscience in the GO. I am also involved in UB’s contribution to the Protein Ontology and contribute as well to the work of the Infectious Disease Ontology Consortium, Immunology Ontology Consortium and Vaccine Ontology Consortium. I teach and mentor students at the master’s and doctoral levels, and advise undergraduate, graduate, and medical students in summer research projects as well.
