Welcome, but be careful
Welcome to Wikipedia. Here are suggested readings: WP:SECONDARY and WP:COI. The gist of these guidelines are: If you have questions, many editors can offer advice. Happy editing.--Smokefoot (talk) 23:58, 10 February 2018 (UTC)
 * Wikipedia prefers citations to reviews and books, not primary journal references (tens of thousands appear annually). Citing secondary sources is the encyclopedic style.
 * Do not cite yourself or your colleagues. It's called conflict of interest.  Many new editors cite themselves mainly.  That behavior is inappropriate.   I can see that you added several references to your early work.  Probably the best way to deal with your COI and primary literature predicament, is to put those references on the Talk page and invite other editors to evaluate the historical record.  I might move them and ask for comments from others (probably none since no one here seems to care much about organic materials).
