• I am a Health Decision Scientist excited by examining health outcomes, access to care, and value-based health care delivery research. My methods interests include decision science, mathematical modeling, economic evaluation and critical appraisal of clinical trials.

    I was lucky enough to have had a rewarding public health career spanning from field work to desk-based research. In Vietnam, I was an HIV prevention program officer at Abt Associates helping neglected but at high-risk female sexual partners of injection drug users. Our programs coached these women in negotiating safer sex, among other domestic and well-being skills, to eliminate the HIV infection. Alongside with other community-based health care interventions, I was always ruminating over how to obtain the best possible outcomes from the programs within a resource-restricted condition. Then I moved on with research on cost-effectiveness analysis and other economic evaluation methods for the valuation of a variety of health care programs. I applied this skill set in evaluating different management strategies for cervical precancer while being at the UTHealth Health Science Center at Houston and MD Anderson Cancer Center. Modeling the diseases, I developed a desire in further understanding the dearth of parameter inputs, inspiring me to join the SWOG Statistical Center at the Fred Hutch Cancer Research Center to learn about the diffusion of new cancer therapies and to conduct cancer care delivery research. I participated in the projects appraising the ultimate value of randomized cancer clinical trials in contributing verified evidence to the clinical guidelines. Experiencing multiple databases, large and small, I plan for research projects using clinically meaningful linked datasets. My career-long goal is to advocate for the usage of economic evidence to facilitate medical decision-making.
