Ongoing Projects / New Work

I have several projects on trace minerals in soil, crop productivity / grain nutrient content, and human health. This involves research on… (i) the impact of zinc deficiency in the soils of Nepal on child stunting and human zinc status, (ii) the influence of soil mineral concentration on crop mineral concentration in Uganda, with implications for measurement of mineral intake, (iii) the link between soil selenium concentration and human selenium status in Malawi, and possibly (iv) the human health implications of arsenic contamination in Pakistan’s groundwater

Opioid deaths 2007-2017

I’m beginning new work modeling opioid addiction, opioid overdose and opioid-related mortality in the Midwest. We will model the effect of local economic/ demographic factors (e.g. poverty), infrastructure (e.g. proximity to highways), health and drug environment (e.g. pill mills, rehabs), and opioid-relevant policies (e.g., police forces with naloxone) on opioid abuse and overdoses. We also plan to leverage high-frequency addiction correlates to model and predict addiction rates at high geographic and temporal resolution, enabling rapid identification of opioid abuse hotspots. More maps here.

Monthly Avg Windspeed in Cebu, Philippines

I have a few other projects measuring variation in child health in poor countries, due to seasonality (Uganda), weather shocks (Tanzania), or policy shocks (India), temperature variation (global), or typhoon exposure (Philippines).
