Genetic risk predictions

Leveraging genome annotations and shared genetic factors across multiple diseases, we develop computationally efficient and statistically powerful methods to identify high risk individuals for better disease monitoring and prevention. We also investigate how non-genetic factors interact with genetic susceptibility to impact disease risks.
