About me
I am a medicinal chemist with a PhD in organic chemistry. I have worked in both academic and industrial settings doing teaching, basic research and applied research mostly in the area of drug discovery.

I currently work for a small company that collaborates with academic labs to pursue drug discovery research and to help them secure funding, such as SBIR grants, that would be otherwise unavailable to them.

I have been actively editing Wikipedia for more than ten years. I try to improve Wikipedia by creating, updating, correcting, organizing, and copyediting articles related to organic chemistry, particularly heterocyclic compounds and natural organic compounds. To get a better idea of my interests, just take a look at some of the articles I have started or this list of the most recent of the ~8000 chemical structure images I have uploaded, or see my contributions.

With my wife and kids, I live in suburban Pennsylvania.


Some nice people have taken the time to give me these pretty things. Thanks.

Pyromorphite
Pyromorphite is a mineral species composed of lead chlorophosphate: Pb5(PO4)3Cl, sometimes occurring in sufficient abundance to be mined as an ore of lead. First distinguished chemically by Martin Heinrich Klaproth in 1784, it was named pyromorphite by Johann Friedrich Ludwig Hausmann in 1813. It is usually green, yellow or brown in color, with a resinous lustre. Crystals are common and have the form of a hexagonal prism terminated by the basal planes, sometimes combined with narrow faces of a hexagonal pyramid. Other forms include crystals with a barrel-like curvature and globular or reniform masses. Pyromorphite is part of the apatite group of minerals and bears a close resemblance physically and chemically with two other minerals, mimetite and vanadinite. This focus-stacked photograph, merged from 26 separate images, shows a sample of pyromorphite extracted from the Resuperferolitica Mine in Santa Eufemia, in the Spanish province of Córdoba. The sample measures 3.5 cm × 3.0 cm × 1.5 cm (1.38 in × 1.18 in × 0.59 in).Photograph credit: David Ifar
