Research Statement

Ben Halland's overall research agenda is focused on two areas, evidence-based medicine and design and analysis for large-scale and high-dimensional non-linear regression problems. Ben’s evidence-based medicine research is directed towards using objective, quantitative evidence to inform decision making in health care, from tailoring therapies to individual patients, to estimating burden of disease, to using predictive analytics to improve diagnostic accuracy, to assessing effectiveness of interventions. Ben’s large-scale and high-dimensional non-linear regression research is largely directed towards methodology enabling the usage of computer simulations to study real systems of interest for which actual experimentation is difficult or impossible.

Academic Bio
