Ongoing Projects / New Work
I have several new projects on trace metals in soil/groundwater, crop productivity / grain nutrient content, and human health. This involves research on… (i) the impact of zinc deficiency in the soils of India and Nepal on child stunting and human zinc status, (ii) the differential impact of soil nutrients vs. maize genotype, in shaping maize zinc status in Uganda, (iii) the impact of arsenic contamination in Indus Valley groundwater on human health in Pakistan, (iv) the impact of unexploded ordinance on trace soil nutrients, agricultural productivity, crop nutrient status and human welfare in Cambodia.

I’m beginning new work modeling opioid addiction, opioid overdose and opioid-related mortality in the Midwest. We’d like to modeling 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.
Working with Zoe Plakias, Arnab Nandi, Mike Vuolo, Mark Patridge
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), or temperature variation (global).
Working with Felix Naschold, Tanvi Rao, Joshua Wilde, Zoe McLaren
Additionally, you can find some of my blogs at Chris Barrett’s research group blog, Economics That Really Matters. I also moderate a geospatial data repository for agricultural economists, stored here. More can be found on the importance of soils within this Nature collection.
