An expanding section. To date, my most significant contribution has been to Henri Moissan, which included a significant expansion and reorganization of content, and the updating of numerous references. I have also contributed to biological exponential growth, osteopontin, and Apolipoprotein E.
I'm currently working on an expansion of electric light as part of the WikiProject Vital Articles 30kB Drive, and have been updating incandescent light bulb in the process. A lot of material on there is poorly sourced. I encourage you to join.
