Research Interests:

Dr. Hamilton has research interests in molecular biology of brain tumors, and neurodegenerative diseases. Research on pediatric brain tumors with Dr. Ian Pollack, a pediatric neurosurgeon has resulted in numerous publications.  In 2005 Dr. Hamilton formed the Brain Tumor Bank for adults.  Current brain tumor research uses IHC, FISH, LOH and mutation analysis on human tissues and correlation to prognosis.  He is Director of the Neuropathology Core of the Pittsburgh ADRC (2002-present) and Director of the Neuropathology Autopsy Brain Bank, which includes independently funded tissue banks for Movement Disorders, ALS and Late Life Mood Disorders.  Current work is focused on correlation of PiB amyloid imaging in vivo and brain pathology at autopsy and vascular factors in dementing diseases.  Dr. Hamilton also supervises the Neurohistology Laboratory which supplies paraffin-embedding, histology and staining services for many neuroscience laboratories at the University of Pittsburgh.  Dr Hamilton is the Case-of-the-Month Editor (1996-present) of Brain Pathology (journal of the International Society of Neuropathology).

Research Grants:

P50 AG05133-26    (PI: Lopez)                            3/30/85 – 3/31/10                     1.80 calendar months

Alzheimer Disease Research Center, Core C: Neuropathology

The three objectives of the Neuropathology Core are to (1) procure and bank brain from autopsies of ADRC patients and controls, (2) perform detailed neuropathologic analysis of all AD cases and (3) maintain well catalogued brain bank.Role: Core Director

Markers as Predictors of Outcome in Gliomas

The major goal of this project is to further characterize the molecular features of tumorigenesis in pediatric malignant gliomas.Role:  Co-Investigator

National Institutes of Health                                        $22,074

Novel Strategies for Brain Tumor Therapy

The unifying hypothesis of this program project grant is that novel therapeutic approaches that take into account the unique features of central nervous system (CNS) tumors will have utility for preventing tumor growth and inducing tumor regression, and will potentiate the effects of conventional treatment approaches, particularly radiotherapy, for inducing glioma cell killing. Role:  Co-Investigator

National Institutes of Health                                        $6,018

Pathways Linking Late Life Depression to Mild Cognitive Impairment and Dementia

The goal of this project is to investigate the relationships among late-life depression (LLD), cognitive impairment and progressive neurodegeneration.Role:  Co-Investigator

National Institutes of Health                                        $10,821

A Bi-Institutional Pilot Study of Vaccinations for Patients with Low Grade Glioma             

The goal of this project is to use tissues from the patient’s own brain tumor to stimulate an immune response.  Role:  Co-Investigator
