Professor Weng Kee Wong Named Yushan Scholar by Taiwan’s Ministry of Education

Professor Weng Kee Wong has been named a 2021 Yushan Scholar by Taiwan’s Ministry of Education. This prestigious award, named after the highest mountain in Taiwan, is bestowed upon top international scholars who are recruited to teach or perform research at Taiwanese universities. As an award recipient, Wong will receive grant support for three consecutive years, allowing him to spend three months each year doing research at the National Cheng Kung University in Tainan, Taiwan. There, he will collaborate with computer scientists, engineers, and data scientists to develop effective, nature-inspired metaheuristic algorithms for applications in statistics.

“My focus is to find various kinds of cost saving experimental designs for accurate inference using different types of high dimensional nonlinear models in the biomedical sciences,” says Wong. He explains, “these powerful and assumption-free algorithms are general optimization tools and are widely used in artificial intelligence, engineering and computer science but seem greatly under-used in statistical research.” Wong hopes that his research will increase the use of these types of algorithms for solving optimization problems in statistics.

Professor Wong hopes to begin his work in Taiwan in June.

Additional recognition for Professor Tom Belin's community-partnered research

Bringing additional recognition to the Community Partners in Care (CPIC) study, which investigated strategies for disseminating evidence-based care for depression in under-resourced areas of Los Angeles through social-service agencies and other community-trusted locations, the most recent issue of the journal Psychiatric Services has highlighted a 2017 article on long-term outcomes from the CPIC study as one of fourteen "Editor's Choice" articles on the theme of "Engaging People with Lived Experience in Mental Health Services and Research" that the journal has published in the past ten years. Professor Tom Belin, who served as the chair of the CPIC study's Design Committee, was listed fourth among the article's 28 co-authors (encompassing 16 academic partners affiliated with UCLA or RAND and 12 community partners affiliated with local non-profit organizations, notably including Healthy African American Families in South Central Los Angeles and Queenscare Health and Faith Partnership in Hollywood and downtown Los Angeles). Previous recognition for the CPIC study included the Team Science Award of the Association for Clinical and Translational Science as well as specific mention as a high-quality study in a 2015 Cochrane Collaboration review of 58 studies of community-coalition interventions. (Citations follow below for both the "Editor's Choice" article and a publication led by Professor Belin on methodological considerations in the CPIC study.)

Joint UCLA-Harvard study led by PhD student Jay Xu finds substantial racial/ethnic disparities in years of potential life lost attributable to COVID-19

A joint UCLA-Harvard study, led by UCLA Biostatistics PhD student Jay Xu, quantified
racial/ethnic disparities in years of potential life lost (YPLL) attributable to COVID-19, finding a consistent pattern across states of non-Hispanic Blacks and Hispanics experiencing disproportionately high and non-Hispanic Whites experiencing disproportionately low COVID-19-attributable YPLL.

The team comprised of researchers at the UCLA Fielding School of Public Health and the Harvard T.H. Chan School of Public Health. UCLA faculty on the study include Tom Belin (Biostatistics), Ron Brookmeyer (Biostatistics, Dean of the UCLA Fielding School of Public Health), Marc Suchard (Biostatistics, Human Genetics, Computational Medicine) and Christina
Ramirez (Biostatistics).

Using years of potential life lost – an epidemiological quantity that measures mortality via the difference between an upper reference age (75 for this study) minus age at death if positive and 0 otherwise – to measure mortality, Xu’s team analyzed COVID-19 mortality data from the National Center for Health Statistics as of December 30, 2020, characterizing YPLL-based
disparities in two ways: (1) estimating percentages of total YPLL by race/ethnicity, contrasting them with their respective percent population shares, and (2) estimating age-adjusted YPLL rate ratios (RR) – anchoring comparisons to non-Hispanic Whites – in each of 45 states and the District of Columbia (D.C.).

To estimate these quantities, an adaptation of a novel Monte Carlo simulation procedure to
quantify the uncertainty of YPLL-based estimates that was recently developed by Xu, Belin, and Ramirez [1] was used. For comparison, Xu’s team also calculated the corresponding percentages total deaths and age-adjusted mortality rate ratios. The results of the analysis revealed that racial/ethnic disparities in the COVID-19 mortality burden are generally greater in magnitude when measuring mortality in terms of YPLL compared to (age-irrespective) death
counts, reflecting the greater intensity of the disparities at younger ages. Xu’s team also found substantial state-to-state variability in the magnitudes of the estimated racial/ethnic disparities, suggesting that they are driven in large part by social determinants of health whose degree of association with race/ethnicity varies by state.

The associated paper is currently undergoing peer review, but a preliminary non-peer reviewed report is available on medRxiv, accessible here.

Crystal Shaw Wins Award For Individual F31 Fellowship

Congratulations to Crystal Shaw for the National Institute of Aging (one of the branches of the National Institutes of Health) awarding $119,456 through June 2023 for an individual F31 fellowship to support Crystal's Ph.D. studies and dissertation research. The award emerged from an April 2020 grant application Crystal prepared entitled "Link, transport, integrate: a Bayesian data integration framework for scalable algorithmic dementia classification in population-representative studies".

The proposed project, which builds on her Graduate Student Researcher role with Professor Elizabeth Rose Mayeda in the UCLA Department of Epidemiology, involves using modern statistical-computing strategies to bridge multiple data sources to enhance the utility of population-based surveys for research on Alzheimer's disease and other precursors of dementia. Department of Biostatistics mentors on the project include Professor Tom Belin, Professor Donatello Telesca, and Professor and Dean Ron Brookmeyer, and Crystal also arranged for the mentorship team to include Jennifer Manly, Ph.D., a Professor of Neuropsychology in Neurology at Columbia University, an internationally recognized Alzheimer's disease researcher with specialization in the role of diagnostic tests in understanding cognition.

In her leadership role of the Biostatistics Student Association, Crystal has graciously offered to make herself available to other students who might similarly be interested in applying for similar training fellowships. So along with congratulations, thanks to you, Crystal, for your efforts on our collective behalf!
