Research interests/plan

I am interested in precisely defining and characterizing the lipids that comprise the brain and retina. We know that at the onset of brain disease and retinal degeneration the component lipids begin undergoing changes, where some disappear, some are reduced, some increase, and some appear for the first time.

My research is centered around mass spectrometry. I extract the lipids of interest and analyze them by conventional mass spectrometry or by MALDI (imaging) mass spectrometry. I have access to two colonies of mice that have been genetically altered so that they now have characteristics of two blinding eye diseases, Age-related macular degeneration (AMD) and retinitis pigmentosa (RP). 

My long-term research plan is to isolate retinas and the underlying retinal pigment epithelium from these mice, as well as those of normal mice, and create lipid profiles of these tissues at the onset of the disease, as well as at various times following disease progression. Regulation of these changes must involve enzymatic activity, so I would like to follow these changes in parallel studies where I define changes in proteins (enzymes). This will require me to initiate mass spectrometric techniques for proteomics, as well as my current work with lipidomics. 

Once characterization has progressed, I wish to compare my results with changes in human degenerative diseases. I can have access to human donor eyes from NIH-sponsored eye banks in which some samples will be normal tissues, while others will be tissues expressing retinal degeneration.  

I hope to define initial causes of these diseases, moving from a mouse study to human analysis, where my results can suggest possible means of intervention to prevent, slow, or halt these pathological conditions.
