Explore trends in tobacco use worldwide and by country for the years 1980 to 2012 with our new interactive data visualization tool. Use the settings below the graphics to focus on a demographic category or measure of interest (e.g., location, year, age, sex, metric).

Data analysis is a complex process with frequent shifts among data formats and models, and among textual and graphical media. We are investigating how to better support the life cycle of analysis by identifying critical bottlenecks and developing new methods at the intersection of visualization, machine learning, and computer systems. Can we empower users to transform and clean data without programming?

In this talk, Dr. Welch will 1) define overdiagnosis: the detection of an “abnormality” that would have otherwise never become evident during the individual’s lifetime; 2) describe the proximate mechanisms for overdiagnosis: a) changing rules, b) seeing more, c) looking harder, and d) stumbling onto things; 3) explore the evidence for overdiagnosis and subsequent harm; and 4) consider approaches to mitigate the problem.

This talk examines the crowdsourcing phenomenon during natural disasters and other crisis events.

Countries in the Arab world -- from Saudi Arabia to Mauritania to Yemen -- have made some significant health gains over the past two decades, including increases in life expectancy and swift reductions in child mortality. But the rise of chronic diseases, diet-related risk factors, and deaths from road injuries during the same period threatens that progress.

This seminar reports on reproductive history interviews with 1,014 Tibetan women 40 years of age and older living at altitudes of 3,000+ meters in Gorkha and Mustang Districts, Nepal, as well as on ethnographic data from the regions. 

In countries with limited vital registration, adult mortality rates are frequently estimated using siblings’ survival histories (SSH) collected during nationally representative surveys such as the Demographic and Health Surveys. Such data may underestimate adult mortality because of reporting errors and omissions of deceased siblings. Dr.

Dr. Jewell’s arrival as an Assistant Professor at Berkeley in 1981 coincided with the peak of the HIV epidemic in the San Francisco Bay Area. From that moment on he was involved in many studies of the epidemiology of AIDS and subsequently intervention and treatment trials. He will discuss some of the statistical challenges associated with population studies of HIV and how methods developed to study the epidemic turned out to have much broader application.

This talk will highlight some of the benefits and challenges associated with harnessing the temporal structure present in many datasets.
