One of my favorite descriptions calls it a “magical, natural, weed killing potion.” That particular potion certainly kills weeds, but […]

Although the title seems pretty straightforward, there are some flaws in the study design that preclude any broad conclusions from this research. […]

An introduction can be found here: On transparency, intimidation, and being called a shill. Since 2012, around two-thirds of my research funding has come from competitive grants. By competitive grants, I mean projects that I’ve developed […]
