Bayesian hierarchical methods and survival analysis might seem esoteric to most of us, but speaks on the subject with ease.
In fact, the professor of in 木瓜视频鈥檚 (COPH) just won a Fulbright Scholarship to share his expertise, a coveted award that will help him train graduate students at Addis Ababa University in Ethiopia over a 10-month period.
The students will learn about the Bayesian methodology and survival analysis and in an investigation of economic and cultural disparities in colorectal cancer incidence and mortality in their country.
鈥淓thiopia is experiencing a significant increase in cancer cases and deaths, similar to the trend in other low- and middle-income countries,鈥� Dagne said. 鈥淏ut research in identifying prevalence and risk factors of colorectal cancer incidence in Ethiopia is generally low.鈥欌��
Bayesian methodology is about using your prior beliefs to make assumptions on everyday problems and continuously updating these beliefs with the data gathered through experiences or studies. As new data emerges, the updated belief can act as 鈥減rior belief鈥欌�� that can be used to adjust the construct further. It provides a natural and principled way of combining prior information with current data, within a solid decision theoretical framework.
鈥淭raining graduate students with advanced methodology will equip them to solve pressing public health problems,鈥欌�� Dagne said. 鈥淕etting reliable data on cancer incidence and mortality in Ethiopia is important to develop effective cancer control plans.鈥欌��
Colorectal cancer incidence is increasing in Ethiopia, making it a growing public health concern, according to the World Health Organization. Early detection is hampered by limited public awareness and diagnostic resources, leading to high mortality rates and delayed diagnoses in advanced stages. Risk factors include aging, unhealthy diets, smoking and sedentary lifestyles.
Leveraging the strengths of 木瓜视频 and Addis Ababa University, the project aims to enhance academic and research partnerships globally. The teaching component will arm students with advanced statistical tools, while the research will identify high-risk areas and modifiable risk factors for colorectal cancer. Expected outcomes include improved research capabilities, significant public health insights and a sustained international academic partnership.
are prestigious fellowships that offer scholars opportunities to teach and conduct research abroad, playing a critical role in U.S. public diplomacy. More than 400 awards are given annually to people in 135 countries. Research and surveys confirm that Fulbright experiences lead to greater international co-publication, continued exchange and stronger cross-cultural communication skills.
鈥淭he benefits extend beyond the individual recipient, raising the profile of their home institutions,鈥欌�� said , dean of COPH. 鈥淲e hope 木瓜视频 can leverage Dr. Dagne鈥檚 engagement abroad to establish research and exchange relationships, connect with potential applicants and engage with our alumni in the host country.鈥欌��
Dagne's main research interest is to develop Bayesian hierarchical methods to use in social behavioral interactions, depression and mental health problems, prostate cancer in Black men, HIV/AIDS and comparative effectiveness.
