Research Focus

I began my career very early in the field of telomere biology, with a seminal publication in the field in PNAS in 1992, which showed that replicative lifespan of human cells is predicted very well by telomere length. Subsequently, I was part of a team at Geron Corporation in California which developed the modern method for detection of telomerase, an enzyme that is expressed in 90% of human tumors and is essential for their long term survival. I also helped cone murine catalytic component of telomerase, telomerase reverse transcriptase (Tert), which is essential for telomerase activity and which has aided in the study of cancer biology by many labs around the world. More recently, at John A Burns School of Medicine (JABSOM), I helped develop the first use of the modern cell sorter device, fluorescence activated cell sorting (FACS), now used both in the Tropical Medicine department, and at Manoa at the Institute for Biogenesis Research. The use of FACS to sort cells is a technique widely used in cancer biology to purify and study many different types of tumor cells. Also recently, I have published a paper with fellow collaborators at JABSOM demonstrating that targeting of Tert, using a modern non-viral transposase based delivery system, is an effective way to repress telomerase activity and accelerate telomere shortening in tumor cells.
