Personal Bio

PhD Stanford University I BA North Central College, Illinois

Although I trained in developmental biology at Stanford University for my PhD and in physiology at the University of California at San Diego in my postdoctoral positions, I acquired an interest in anticancer drug development through my connections with the natural product and synthetic chemists at VUW. My major scientific contribution has been to identify the mode of action of two important compounds isolated from marine sponges, peloruside and zampanolide. These bioactive compounds disrupt the function of a cell’s cytoskeletal component, the microtubule, have a nanomolar antimitotic effect on cells, and have good potential for further development as anticancer therapeutics. I am also investigating the use of microtubule-targeting agents in the treatment of Alzheimer’s disease and multiple sclerosis. In addition to these agents that disrupt microtubule function, my current research is directed toward heparan sulfate compounds that inhibit the enzyme heparanase, which plays an important role in cancer cell metastasis.

Research interests

Mechanism of Action of Marine Natural Products: I am investigating the mode of action of microtubule-stabilizing agents isolated from marine sponges for development as anti-cancer drugs. We are also exploring the potential therapeutic use of these bioactive compounds in diseases of inflammation, such as multiple sclerosis, and in neurodegenerative diseases like Alzheimers Disease. I am currently focusing on interactions of these drugs with their primary and secondary protein targets, using semi-synthetic analogs to determine their structure-activity relationships.

Neurochemistry of Drug Abuse: I am also interested in the effects of MDMA (ecstasy), cannabis, and tobacco smoke extracts on brain neurochemistry. Currently we are investigating the links between cannabinoid receptors and opioid receptors and their effects on learning and memory.
