I am an analytical chemist, although I just graduated with a masters degree in paleontology.
I support the charity Awareness, Respect, Compassion (arcnow.org). Started by Jee Jee Kim, an alum of George Washington University, ARC collects donations of knitted and crocheted winter clothing for people of all ages and also small crocheted/knitted toys for kids. These items are sent to Life Funds for North Korean Refugees, a Japanese organization that helps the people who have escaped from the communist state. The charity also collects items, such as cat/dog mats and beds, for the Washington Humane Society in Washington, D.C. Jee Jee also supports the Pine Ridge Emergency Youth Shelter in South Dakota and the Family Crisis Center Inc. of Prince George's County in Maryland.
Since 2009, I have donated 641 crocheted and knitted items to charity. I had supported two other charities, but they no longer function as they did. ARC is currently the primary charity I support.
