I collaborate with various scientific groups in my research lab, but I primarily focus on oncology and experimental hematology research. I am mainly interested in the application of medicinal chemistry, virtual screening and cheminformatics. I also participate in projects across other disciplines and focus areas.

I received my doctorate in chemistry from Harvard University and then spent 19 years in the discovery field of migraine and antimicrobial drugs. From my experience in the pharmaceutical industry, I moved toward utilizing and optimizing the technology and tools that streamline efforts in drug design. For example, I led technology groups in protein modeling, computational chemistry, structural biology and combinatorial chemistry. I later served as a project manager for the University of Cincinnati Drug Discovery Center and direct the College of Medicine’s Compound Library.

I began working at the Cincinnati Children’s Hospital Medical Center in 2013, after more than 25 years of experience in the field of drug discovery. My role at the Cincinnati Children’s Hospital Medical Center has been to employ these tools and expertise to assist others in their research studies. I’ve always been interested in working with numerous collaborators and investigators to 1) identify the most effective methods of discovering biologically active small molecules and 2) advance these findings toward the clinic. My research has been published in numerous respected journals, including Oncotarget, PLoS ONE, Methods in Molecular Biology, Cell Chemical Biology and Nature Communications.

PhD: Harvard University, Cambridge, MA, 1987.
